Answer:
6.15.
Step-by-step explanation:
3.75 + 2 2/5
= 3.75 + 2.40
= 6.15.
Since he can run 1/4 of a mile in 2.5 minutes, he will run a full mile in 4*2.5 =10 minutes, assuming he runs at a steady speed.
Answer:
W-2 form
Step-by-step explanation:
Answer:
The correct option is 3. The image of X is X'(6,2).
Step-by-step explanation:
means the dialation by scale factor 2 and the center of dilation is Z.
If a figure dilated by scale factor k and the center of dilation is (a,b), then
From the given figure it is clear that the coordinates of X are (4,0) and the coordinates of Z are (2,-2), so the coordinates of image are
The image of X is X'(6,2). Therefore the correct option is 3.
Answer: 15x² + 2x + 4
x = -2/3, 0, 1/2
Step-by-step explanation:
5x(3x + 2) - 4(2x - 1)
First, distribute:
15x² + 10x - 8x + 4
Combine like terms:
15x² + 2x + 4
This is your polynomial!
If you needed to solve for x, take your original factored polynomial and set each term equal to 0:
5x(3x + 2) - 4(2x - 1)
5x = 0
x = 0
3x + 2 = 0
3x = -2
x = -2/3
-4 = 0
No solution
2x - 1 = 0
2x = 1
x = 1/2
x = -2/3, 0, 1/2
Hope this helps!
