2x+8=20
2x=20-8
2x=12
12/2=x
6=x
Answer:
y = 1/2x -2
Step-by-step explanation:
The slope of the equation is over 1 and to the right by 2 so Rise/run = 1/2
The y-intercept is -2
.6% will be a decimal because when u move u only had to move two time to the right side
Answer:
When k(x) is 2x² - 5x + 3, k(-3) = 36.
Step-by-step explanation:
k(x) = 2x² - 5x + 3
Substitute the input of x.
k(-3) = 2(-3)² - 5(-3) + 3
Square -3.
k(-3) = 2(9) - 5(-3) + 3
Multiply 2 and 9.
k(-3) = 18 - 5(-3) + 3
Multiply -5 and -3.
k(-3) = 18 + 15 + 3
Add 18 and 15.
k(-3) = 33 + 3
Add 33 and 3.
k(-3) = 36.
