Answer:

Alright well to find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept substitute in 0 for x and solve for y

X-intercept: (9/13, 0)

Y-intercept: (0, 1/2) Hope this helps :)

6x + 5y=-13
y=-7x+9

6x + 5(-7x +9) =-13
6x -35x + 45 = -13
-29x + 45 = -13
-45. -45
-29x = -58
/-29
x = 2

y = -7x + 9
y = -7(2) + 9
y = -14 + 9
y = -5

What is the solution of this system of linear equations? 3y = x + 6 y – x = 3

Greeley [361]

Hello :
<span>3y = x + 6 ...(1)
y – x = 3...(2)
by (2) : y = x+3...(*)
subsct in (1) :
3(x+3) = x+6
3x-x= -9+6
2x= -3
x=-3/2
subsct in (*) : y =-3/2 +3 =3/2</span>

I need to find the parent function and compare and contrast the domain and range of the parent function.

denpristay [2]

The parent function is f(x) = x^3 with domain = all real numbers and range = all real numbers.

The given function is f(x) = x^3 - 2 with domain = all real numbers and range = all real numbers.
