3x12-12=24
3[26-2x9]=3[8]=24
The ? should be replaced with an equal sign because both sides equal 24.
A) Slope: (y2 - y1) / (x2 - x1)
You can use point (-1, -6) and (0, -8)
Slope = (-8 - -6) /(0 - -1) = (-8+6)/(0+1) = -2/1 = -2.
Slope = -2.
b) Point (0, -8) is the point such that x = 0, and y = -8, this point represents the vertical intercept of the equation. The point where the line cuts the y axis.
Answer:
D
Step-by-step explanation:
Distributive property: a*(b+c) = a*b + b*c
-7(8x - 3) + x = -7*8x - 3 * (-7) + x
= -56x + 21 + x {Bring the like terms together}
= -56x + x + 21 {Now, add the like terms}
= -55x + 21
