5x³ + 8x² - 7x - 6
1)
x + 2 is a factor because when using synthetic division, the remainder is zero.
-2 | 5 8 -7 -6
<u>| ↓ -10 4 6 </u>
5 -2 -3 0 ← remainder is zero
2)
x + 2 is not a factor because when using synthetic division, the remainder is not zero.
-1 | 5 8 -7 -6
<u>| ↓ -5 -3 10 </u>
5 3 -10 4 ← remainder is not zero
I am pretty sure this is the answer.
Answer:
The slope is 0
Step-by-step explanation:
m= (y2-y1)(x2-x1)
y2 is -3, y1 is -3
x2 is 1 and x1 is -9
m= -3-(-3)/1- (-9)
m=0/10
m= 0
Answer:
Line W'X' is 4 times longer than line WX.
Step-by-step explanation:
When we dilate a figure by a scale factor, the side length increases by that scale factor. If the length was 1 before the dilation, and the scale factor is 2, the length would be 2 after the dilation because 1*2=2. Assuming that WX and W'X' are sides of the figure because no image was provided, the dilated side should be 4 times longer.
