Answer:

y = x - 2

Step-by-step explanation:

Parallel lines have the same slope, so the line will also have a slope of 1.

Plug in the slope and given point into y = mx + b to solve for b:

y = mx + b

-1 = 1(1) + b

-1 = 1 + b

-2 = b

Plug in b and the slope into y = mx + b

y = x - 2 is the equation

Y = 500(1 + r)^x; where r is the rate and x is the number of years.
500(1 + r)^2 = 551.25
(1 + r)^2 = 551.25/500 = 1.1025
1 + r = sqrt(1.1025) = 1.05

Therefore, the equation that represents y, the value of the item after x years is
y = 500(1.05)^x

Solve the following system of equations . y = - x + 7, \qquad 4x - 5y = 10 Write your answer as an ordered pair in the form(x,y)
Mnenie [13.5K]

Answer:

(5, 2)

Step-by-step explanation:

Lets substitute y = -x + 7 into 4x-5y=10

Then we can write 4x-5y=10 as 4x-5×(-x+7)=10,

4x-(-5x)-35=10

9x-35=10

9x=45

x=5, therefore, y= -5+7=2
