Which point(s) are solutions to the inequality -x - 2y > 3? Select all that apply.
A. (-1, -2)
B. (1, -2)
C. (-2, -1)
D. (2.-4)
(-1, -2), (-2, -1) and (2, -4) are solutions to the inequality
The given inequality is:
-x - 2y > 3
To know which of the points given as options are the solutions to the given inequality, substitute the given points into -x - 2y, anyone that gives a result greater than 3 is a solution to the inequality
For (-1, -2)
Substitute x = -1, and y = -2 into -x - 2y
-(-1) - 2(-2)
= 1 + 4
= 5
Since 5 > 3, (-1, -2) is a solution to the inequality
For (1, -2)
Substitute x = 1, and y = -2 into -x - 2y
-(1) - 2(-2)
= -1 + 4
= 3
Since the result is not greater than 3, (1, -2) is not a solution to the inequality
For (-2, -1)
Substitute x = -2, and y = -1 into -x - 2y
-(-2) - 2(-1)
= 2 + 2
= 4
Since 4 > 3, (-2, -1) is a solution to the inequality
For (2, -4)
Substitute x = 2, and y = -4 into -x - 2y
-(2) - 2(-4)
= -2 + 8
= 6
Since 6 > 3, (2, -4) is a solution to the inequality
Therefore, (-1, -2), (-2, -1), and (2, -4) are solutions to the inequality

Answer:B
Step-by-step explanation:
Write a function that is passed in a positive integer, n, and sum up all the digits from 1 to n, doubling the even numbers. In other words, calculate and return the following sum. if n is odd: 1 (2 * 2) 3 (4 * 2) ... ((n - 1) * 2) n if n is even: 1 (2 * 2) 3 (4 * 2) ... (n - 1) (n* 2)
Answer:
Written in Python
def sums(n):
total = 0
for i in range(1,n+1):
if i%2 == 0:
total = total + i*2
else:
total = total + i
return(total)
Step-by-step explanation:
The function is written in Python
def sums(n):
This initializes total to 0
total = 0
This iterates through the integers that makes up n i.e. 1,2,3.....n
for i in range(1,n+1):
This checks if current digit is even
if i%2 == 0:
If yes, it adds the double of the digit
total = total + i*2
else:
If otherwise, it adds the digit
total = total + i
This prints the calculated sum or total
return(total)
To call the function from main, use the following:
print(sums(n))
Where n is a positive integer. i.e. [tex]n \geq 1[/tex]

questions are on the image below :)
Answer:
1. [tex]y = 3x[/tex]
2. [tex]y = -\frac{2}{3}x + 1[/tex]
3. [tex]y = -\frac{2}{3}x - 4[/tex]
4. [tex]y = 4[/tex]
5. [tex]y = x + 5[/tex]
6. [tex]y= \frac{5}{2}x[/tex]
7. [tex]y = -7x -16[/tex]
8. [tex]y = x + 4[/tex]
Step-by-step explanation:
The steps to solving these questions involve
1. Calculate slope using: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
2. Calculate the line equation using point slope formula: [tex]y - y_1 = m(x - x_1)[/tex]
We'll apply the steps above in solving 1 through 8
Solving (1):
When x = 0; y = 0
When x = 1; y = 3
i.e.
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (1,3)[/tex]
Calculate slope:
[tex]m=\frac{3 - 0}{1 - 0}[/tex]
[tex]m=\frac{3 }{1 }[/tex]
[tex]m = 3[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (0,0)[/tex] and [tex]m = 3[/tex]
[tex]y - 0 = 3(x - 0)[/tex]
[tex]y = 3x[/tex]
Solving (2):
When x = 0; y = 1
When x = 3; y = -1
i.e.
[tex](x_1,y_1) = (0,1)[/tex]
[tex](x_2,y_2) = (3,-1)[/tex]
Calculate slope:
[tex]m=\frac{-1 - 1}{3 - 0}[/tex]
[tex]m= -\frac{2}{3}[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (0,1)[/tex] and [tex]m= -\frac{2}{3}[/tex]
[tex]y - 1 = -\frac{2}{3}(x - 0)[/tex]
[tex]y - 1 = -\frac{2}{3}(x)[/tex]
[tex]y - 1 = -\frac{2}{3}x[/tex]
[tex]y = -\frac{2}{3}x + 1[/tex]
Solving (3):
When x = 0; y = -4
When x = -3; y = -2
i.e.
[tex](x_1,y_1) = (0,-4)[/tex]
[tex](x_2,y_2) = (-3,-2)[/tex]
Calculate slope:
[tex]m=\frac{-2 - (-4)}{-3 - 0}[/tex]
[tex]m=\frac{-2 +4}{-3 - 0}[/tex]
[tex]m=\frac{2}{-3}[/tex]
[tex]m=-\frac{2}{3}[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (0,-4)[/tex] and [tex]m= -\frac{2}{3}[/tex]
[tex]y - (-4) = -\frac{2}{3}(x - 0)[/tex]
[tex]y +4 = -\frac{2}{3}(x)[/tex]
[tex]y +4 = -\frac{2}{3}x[/tex]
[tex]y = -\frac{2}{3}x - 4[/tex]
Solving (4):
When x = 0; y = 4
When x = 4; y = 4
i.e.
[tex](x_1,y_1) = (0,4)[/tex]
[tex](x_2,y_2) = (4,4)[/tex]
Calculate slope:
[tex]m=\frac{4 - 4}{4 - 0}[/tex]
[tex]m=\frac{0}{4}[/tex]
[tex]m = 0[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (0,4)[/tex] and [tex]m = 0[/tex]
[tex]y - 4 = 0(x - 0)[/tex]
[tex]y - 4 = 0[/tex]
[tex]y = 4[/tex]
Solving (5):
When x = -4; y = 1
When x = -1; y = 4
i.e.
[tex](x_1,y_1) = (-4,1)[/tex]
[tex](x_2,y_2) = (-1,4)[/tex]
Calculate slope:
[tex]m=\frac{4 - 1}{-1 - (-4)}[/tex]
[tex]m=\frac{4 - 1}{-1 +4)}[/tex]
[tex]m=\frac{3}{3)}[/tex]
[tex]m = 1[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (-4,1)[/tex] and [tex]m = 1[/tex]
[tex]y - 1 = 1(x - (-4))[/tex]
[tex]y - 1 = 1(x +4)[/tex]
[tex]y - 1 = x +4[/tex]
[tex]y = x +4 + 1[/tex]
[tex]y = x + 5[/tex]
Solving (6):
When x = 0; y = 0
When x = 2; y = 5
i.e.
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (2,5)[/tex]
Calculate slope:
[tex]m=\frac{5 - 0}{2 - 0}[/tex]
[tex]m=\frac{5 }{2 }[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (0,0)[/tex] and [tex]m=\frac{5 }{2 }[/tex]
[tex]y - 0 = \frac{5}{2}(x - 0)[/tex]
[tex]y - 0 = \frac{5}{2}(x)[/tex]
[tex]y= \frac{5}{2}x[/tex]
Solving (7):
When x = -2; y = -2
When x = 2; y = 5
i.e.
[tex](x_1,y_1) = (-2,-2)[/tex]
[tex](x_2,y_2) = (-3,-5)[/tex]
Calculate slope:
[tex]m=\frac{5 - (-2)}{-3 - (-2)}[/tex]
[tex]m=\frac{5 +2}{-3 +2}[/tex]
[tex]m=\frac{7}{-1}[/tex]
[tex]m =-7[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (-2,-2)[/tex] and [tex]m =-7[/tex]
[tex]y - (-2) = -7(x - (-2))[/tex]
[tex]y +2 = -7(x +2)[/tex]
[tex]y +2 = -7x -14[/tex]
[tex]y = -7x -14 - 2[/tex]
[tex]y = -7x -16[/tex]
Solving (8):
When x = -3; y = 1
When x = 0; y = 4
i.e.
[tex](x_1,y_1) = (-3,1)[/tex]
[tex](x_2,y_2) = (0,4)[/tex]
Calculate slope:
[tex]m = \frac{4 - 1}{0 - (-3)}[/tex]
[tex]m = \frac{4 - 1}{0 +3}[/tex]
[tex]m = \frac{3}{3}[/tex]
[tex]m = 1[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (-3,1)[/tex] and [tex]m = 1[/tex]
[tex]y - 1 = 1(x - (-3))[/tex]
[tex]y - 1 = 1(x +3)[/tex]
[tex]y - 1 = x +3[/tex]
[tex]y = x + 3 + 1[/tex]
[tex]y = x + 4[/tex]

Questions – Impulse and Momentum
A 6.00 N force acts for 5.00 seconds on a 1.50 kg mass. Find:
A) The impulse which acted upon the mass.
B) What change in momentum is produced?
The value of the impulse will be 30 Newton-second. And the value of the momentum will be 30 kg-m/s.
What are impulse and momentum?A strong and ignorant passion or drive to act is known as an impulse.
A traveling body's momentum is measured as the combination of its mass and velocity.
A 6.00 N force acts for 5.00 seconds on a 1.50 kg mass.
Then the impulse is given as
Impulse = Force x Time
Impulse = 6 x 5
Impulse = 30 N-sec
Then the value of the momentum will be
P = m x dv
We know
F = ma
6 = 1.5a
a = 4 m/s²
Then the velocity will be
dv = a x t
dv = 4 x 5
dv = 20 m/s
Then the momentum will be
P = 1.5 x 20
P = 30 kg-m/s
More about the impulse and momentum link is given below.

Which of the following is closer to 8
√61
√62
√65
√66
Answer:
√65
Step-by-step explanation:
We know that √64 is 8
So, the square root of the number closest to 64 in the list will be the closest to 8
In the List, √62 = √(64-2) [difference of 2]
√65 = √(64 + 1) [difference of 1]
Since √65 has the least difference from √64, we can say that √65 will be the closest to 8 in the given list

a car travels at a rate of 120 kilometer per hour if 1 mile equals 1.6 kilometer which equation could be used to find the number of miles the car travels per hour ?
Answer:
75
Step-by-step explanation:
120 ÷ 1.6 = 75 since 1.6 kilometer per hour is 1 mile, the car travels 75 miles per hours
Answer:
The car travels 75 miles per hour
Step-by-step explanation:
Units of Length
The most common units of distance are millimeters, centimeters, meters, miles, and kilometers.
The equivalence from miles to kilometers is:
1 mile = 1.6 Kilometers
If we wanted to convert a given distance from kilometers to miles, we'd need to divide by 1.6, that is:
d(miles) = d(km)/1.6
The above equation can be used to find the number of miles given the number of kilometers.
If a car travels at 120 kilometers per hour, then in one hour it travels
d(km)=120
Thus, the distance in miles is:
d(miles) = 120/1.6 = 75
The car travels 75 miles per hour
The population of Laredo, Texas, was about 215,500 in 2007. It was about 123,000 in 1990. If we assume that the population growth is constant and t represents the number of years after 1990, write a linear equation
Answer:
y=5441t+123,000
Step-by-step explanation:
5441 is the population increase per year and 123,000 is when we start added the population increase. to get this equation i found the population increase between 2007 and 1990 which is 215,500-123,000 which is 92,500. to find the population increase per year you divide that by 17 which is the difference between 2007 and 1990 and you would get 5441.176. but since you can have part of a person i rounded it to 5441.
Answer: y=5441t+123000
We know the population was 215500 in 2007
We also know the population was about 123000 in 1990
So first we want to find the slope (m=y2-y1/x2-x1), we subtract those two numbers 215500-123000 and subtract 2007-19990. Leaving us with 92500/17, once you divide that you’ll get 5441.17647 . But since we are talking about people you round to the nearest whole number leaving us with 5441.
