solve for y
2x−4y=10
-2x -2x subtract -2x from both sides
-4y = -2x +10
-4 -4 Divide both sides by -4 (coefficient on y)
y = -2/-4x + 10/-4
y = 1/2x - 5/2
the slope is the number on the x (coefficient)
and its 1/2
Answer:
C
Step-by-step explanation:
Given
x² - 6x + 9
Consider the factors of the constant term (+ 9) which sum to give the coefficient of the x- term (- 6)
The factors are - 3 and - 3, since
- 3 × - 3 = + 9 and - 3 - 3 = - 6, thus
x² - 6x + 9 = (x - 3)(x - 3) = (x - 3)² → C
Answer:
-22
Step-by-step explanation:
f(x) = -2x^2 - 4 for x = 3
f(3) = -2(3)^2 - 4
f(3) = -2(9) - 4
f(3) = -18 - 4
f(3) = -22
Answer: -22
