Answer:
(-2, -5)
(-1, -3)
(0, -1)
(1, -1)
(2, 3)
Step-by-step explanation:
To do this you simply put in an input for x and then solve and you will get your y.
We'll use
x= -2 for this input
y=2(-2)-1
y=-4-1
y=-5
(-2, -5) Is one ordered pair
We'll use
x= -1 for this input
y=2(-1)-1
y=-2-1
y=-3
(-1, -3) Is another ordered pair
We'll use
x= 0 for this input
y=2(0)-1
y=0-1
y=-1
(0, -1) is another ordered pair
We'll use
x= 1 for this input
y=2(1)-1
y=2-1
y=1
(1, -1) is another ordered pair
We'll use
x= 2 for this input
y=2(2)-1
y=4-1
y=3
(2, 3) is the last pair I'll use today.

Samantha invested $660 into an account that paid 3.5% interest compounded annually. Samantha did not make any additional deposits or withdrawals. What is the total amount of interest paid by this investment at the end of 5 years?
115.5 is the total amount of interest paid by this investment at the end of 5 years
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
Samantha invested $660 into an account that paid 3.5% interest compounded annually.
We need to find total amount of interest paid by this investment at the end of 5 years
A=P(1+rt)
A is final amount
P is principal amount
r is rate of interest
t is time
A=?,P=660,r=3.5%=0.035, t=5
A=660(1+0.035(5))
=660(1+0.175)
=660(1.175)
A=775.5
To check the total amount of interest paid by this investment at the end of 5 years
We need to find difference between initial amount and final amount
775.5-660
115.5
Hence 115.5 is the total amount of interest paid by this investment at the end of 5 years

Solve for x.
Answer:
x = 17
Step-by-step explanation:
Since 2 sides of the triangle are congruent then it is isosceles, so
The 2 base angles are congruent, both 29°, thus
11x - 65 = 180 - (29 + 29) = 180 - 58 = 122 ( add 65 to both sides )
11x = 187 ( divide both sides by 11 )
x = 17

Joe is traveling from one city to another. He is looking at a map and realizes that 4 cm represents 25 miles.He then used a ruler to measure the distance on the map between two cities that he is traveling. The distance between them is 160 cm. How far, in miles are the two cities apart?
Answer:
The two cities are 1,000 miles apart
Step-by-step explanation:
The key to solving this is in the scale given:
4cm represents 25 miles
4cm = 25 miles
∴ 1 cm = 25 ÷ 4 = 6.25 miles
Measured distance on map = 160cm
1 cm = 6.25 miles
∴ 160 cm = 160 × 6.25 = 1000 miles
∴ The two cities are 1,000 miles apart

use the subsitution method to slove the system of equations.Choose the correct ordered pair. x+3y=9 y=x-5
Answer:
(6, 1)
Step-by-step explanation:
We are given the equation for (y), [y=x-5]
So we can implement that in all the places the (y) are in the other equation.
x+3(x-5)=9
x+3x-15=9
add 15 to each side
4x=24
Divide each side by 4
x=6
Now we can apply our (x) into one of the equations.
y=(6)-5
y=1
So our solution is (6, 1)

Answer:
y = 2x - 7
Step-by-step explanation:
The question is asking for slope-intercept form, y = mx + a.
Given:
(1, -5) and (9, 11)
Find the slope (m) between the two points:
m = (y2 - y1) / (x2 - x1)
x1 = 1
x2 = 9
y1 = -5
y2 = 11
m = ( 11 - (-5) )/(9 - 1)
= 16/8
m = 2
y = 2x + a
Use one of the two points to find a (I will use (1, -5)):
-5 = 2(1) + a
-5 = 2 + a
-7 = a
a = -7
y = 2x + (-7)
y = 2x - 7

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,
They have $30.00 to spend between them.
let $x be the amount each contributed.
So, the equation to determine how each of them contributed
x = 30/ 5
x= $6.

Sam and Sara bought the same number of pencils. Sam put ¼ of his pencils in his pencil box and Sara put ½ of her pencils in her pencil box. If sam had put 5 in his box then how many pencils did sara put in her pencil box?
Answer:
10 pencils
Step-by-step explanation:
Given that:
Number of pencils bought by Sam and Sara are the same.
Let the number of pencils bought = x
Sam put 1/4 in his pencil box
Sara put 1/2 in her pencil box
1/4 of Sam's pencil = 5
That is ;
1/4 of x = 5
x /4 = 5
x = 20
Hence, number of pencils Sara put in her box
:
1/2 of 20
1/2 * 20
