Answer:
-12w^3+32w^2-136w+80
Step-by-step explanation:
4(2-3w)(w^2-2w+10)
multiply first two:
(8-12w)(w^2-2w+10)
multiply:
8w^2-16w+80-12w^3+24w^2-120w
simplify:
-12w^3+32w^2-136w+80
Answer:
Step-by-step explanation:
4.5 is equal to nine halves because if you divide 9 you get 4.5
Answer:
-75 0 25 50
Step-by-step explanation:
Answer:y = - 2x + 17
Step-by-step explanation:
The equation of a line, represented in the slope-intercept form, is
y = mx + c
Where
Slope = m
c = intercept
Looking at the equation given,
y=1/2x + 8
Slope,m = 1/2
If a line is perpendicular to a another line, then the slope of one line is equal to the negative reciprocal of the other line. It means that the slope of the perpendicular line that passes through that passes through ( 4, 9 ) will be -2
To determine c,
We will substitute m = -2, y = 9 and x = 4 into the slope intercept equation,
y = mx + c. It becomes
9 = -2 × 4 + c
9 = -8 + c
c = 9 + 8 = 17
The equation becomes
y = - 2x + 17
