Answer:
The range of the function y = x2 is all real numbers, y, such that y ≥ 0. In the case of the function y = x2, the domain consists of all real numbers, because there is no number that, when plugged in for x into x2, would create an undefined expression.
Step-by-step explanation:
Answer:
5x + 1
Step-by-step explanation:
-5x - 1
to make -5x positive you have to divide both sides by -1
5x + 1
Hope this helps!!!
Using Substitute method:
Replace y value of equation 2 into equation 1:
4x + (x+6) = 1
Solve for x:
4x + x + 6 = 1
5x = 1 - 6
5x = -5
x = -5/5
x = -1
Pick any of the two equation, replace x with it's value -1 and solve for y:
y = (-1) + 6
y = -1 + 6
y = 5
Solution: (-1, 5)
