What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The linear equation is given below.
y - 4 = 1/2 (x - 1)
Convert the equation into a slope-intercept form. Then we have
y - 4 = 1/2 (x - 1)
y - 4 = x/2 - 1/2
y = x/2 - 1/2 + 4
y = x/2 + 7/2
The equation in the slope-intercept form will be y = x/2 + 7/2. Then the slope of the equation is 1/2.

Which situation involves a change modeled by a positive number but an end result modeled by a negative number? A.Leo enters an elevator on the second floor and goes down four floors. B. A plane, flying at an altitude of 300 feet, descends 50 feet. C. Irene is scuba diving at –30 feet. She swims 10 feet toward the surface to watch a school of fish. D. April owes her brother $5. On Friday, she gets $10 for her allowance.
Answers
The positive number but a negative result would be :
C. Irene is scuba diving at –30 feet. She swims 10 feet toward the surface to watch a school of fish.
The positive value is she swam 10 feet up to the surface, but she is still below the surface, which would be a negative result.
The situation that would involve a change that is from a positive number but ended in a negative number is option C.
This option tells us that at the negative number she was 30 feet below the surface of the water, while at positive number she was 10 feet up the water surface.

Answer:
x = 350 gallons (amt of 60% solution that must be added)
Step-by-step explanation:
Amt of 60% solution = x gallons ; Amt of active ingredient = 0.6x gallons
Amt of 15% solution = 100 gallons ; Amt of active ingredient = 15 gallons
Amt of 50% solution = 100+x gallons ; Amt of active = 50 + 0.5x gallons

Active ingredient: 0.60x + 15 = 50 + 0.50x
0.10x = 35

noAlex is drawing rectangles with different areas on a centimetre grid he can draw 3 different rectangles with an area of 12cmsquared a) How many different rectangles could alex draw with an area of 11cmsquared? B)Give a reason for ur anwser
Answers
Answer:
Alex can only draw a rectangle with an area of 11 cm²
The reason for the answer is that 11 is a prime number
Step-by-step explanation:
We are told that Alex is drawing rectangles with different areas on a centimeter grid, and he can draw 3 different rectangles with an area of 12 cm²
We have the minimum grid length of centimeters = 1 cm, since we assume that only integers can be used.
That is to say:
12 = 1 x 12
12 = 2 x 6
12 = 3 x 4
These are the 3 different rectangles with an area of 12 cm²
Now we have to find how many rectangles Alex could draw with an area of 11 cm²
11 = 1 x 11
Therefore, only one factorization is possible. Which means that you can only draw a rectangle with an area of 11 cm²
The reason for the answer is that 11 is a prime number, which means only the common factor of 1 and the number itself, that is, 11.
Terry bought some gum and some candy. The number of packs of chewing gum was one more than the number of mints. The number of mints was three times the number of chocolate bars. If gum cost 6 cents a pack, mints cost 3 cents each, and chocolate bars cost 10 cents each, how many of each confection did he get for 80 cents?
Answers
Answer:
Hi!!
Step-by-step explanation:
7 = chewing gum
6 = mints
2 = chocolate
Answer:
number of packs of chewing gum is 7
number of mints is 6
number of chocolate bars is 2
Step-by-step explanation:
number of packs of chewing gum → x, cost 6¢
number of mints → y = x-1 =3z, cost 3¢
number of chocolate bars → z = y/3 = (x-1)/3, cost 10¢
put in equation 6x + 3y +10z = 80 plug in term of x
6x +3(x-1) +10((x-1)/3) =80 multiply each side by 3
18x +9(x-1) +10(x-1) =240 distribute
18x+9x-9+10x-10 =240 combine like terms
37x-19 = 240 add 19 in each side
37x =259
x = 7
plug into y = x-1 = 7-1 = 6 so y=6
and z = y/3 =6/3 =2 so z = 2

PLEASE HELP ... how many students are in each van? And how many students are in each bus ?
Answers
Answer:
7 students in each van and 52 students in each bus.
Step-by-step explanation:
v = no of students in van, b = no of student in bus
High school A ⇒ 3v + 6b = 333 ---------- Equation (1)
High school B ⇒ 11v + 6b = 389 ------------ Equation (2)
Solve equation (1) & (2) simultaneously :
11v + 6b = 389
3v + 6b = 333
----------------------- MINUS
8v + 0 = 56
v = 56 / 8
v = 7
Put v = 7 into Equation (1) to get b:
3v + 6b = 333
3 (7) + 6b = 333
21 + 6b = 333
6b = 312
b = 312 / 6
b = 52
So there are 7 students in each van and 52 students in each bus.
Evaluate this expression for a = 3 and b = 4.

Determine and prove which lines are parallel.: Need by Tuesday!! Thanks!
Answers
If the gradients are not the same, then there will be a point, which intersects. That contradicts the statement that theclines have no points in common.
Step-by-step explanation:
Parallel lines are lines that have the same gradient.
Because parallel lines have a fixed distance between each other,it means they will never meet, no matter how long they are extended.
Since parallel lines have the same slope by definition, they will never intersect. Parallel lines continue, literally, forever without touching.
Prove:
Suppose that there are two lines, line l and line m, which have no points in common. Both lines are in the same plane.
If the gradients are not exactly the same, then there will be a point, which intersects. That contradicts the first statement (which says l and m have no points in common), therefore the gradients must be the same in order for l and m to have no points in common.
Scores of an IQ test have a bell-shaped distribution with a mean of 100 and a standard deviation of 20. Use the empirical rule to determine the followinWhat percentage of people has an IQ score greater than 120?
Answers
Answer:
Percentage of people with IQ greater than 120 is 84.134%
Step-by-step explanation:
First thing we do here is to calculate the
z-score
Mathematically;
z-score = (x-mean)/SD
here, x = 120, mean = 100 while SD = standard deviation = 20
z-score = (120-100)/20 = 20/20 = 1
The probability we want to calculate is;
P(x > 120) or P(z >1)
we proceed to use the standard score table to get this;
From the standard score table ;
P(z >1) = 0.84134
which is in percentage = 84.134%

Good luck on your website
Answer:
C. 31.4 cm
Step-by-step explanation:
→The formula for finding the circumference of a circle is:
C = 2πr
→However, it states that we use 3.14 for π:
C = 2(3.14)r
→The "r," is the radius, which is a straight line from the perimeter to the center. In this case, it is already given to us as 5 cm.
C = 2(3.14)(5)
C = 31.4
