Answer:
-2, and 3
Step-by-step explanation:
-x² +x +6 = 0 is the same as
x²-x-6=0
but, x² -Sx+P=0
think what 2 numbers have the sum =1 and product = -6 that will be -2 and 3 witchh are your zeros
or you can use the graph or quadratic formula to solve
The scale factor which used to perform the dilation was 0.4
Step-by-step explanation:
If point (x , y) is dilated about the origin by a scale factor k, then
- Its image is point (kx , ky)
- If k > 1, then kx > x and ky > y
- If 0 < k < 1, then kx < x and ky < y
∵ Δ RST is dilated about the origin O to create Δ R'S'T'
- Assume that the scale factor is k
∵ Point R is (3 , 9)
∴ x = 3 and y = 9
∵ Point R' is (1.2 , 3.6)
∴ kx = 1.2 and ky = 3.6
∵ x = 3 and kx = 1.2
- Substitute x in kx to find k
∴ k(3) = 1.2
∴ 3k = 1.2
- Divide both sides by 3
∴ k = 0.4
To check your answer use the y-coordinates of R and R' to find k
∵ y = 9 and ky = 3.6
- Substitute the value of y in ky to find k
∵ k(9) = 3.6
∴ 9k = 3.6
- Divide both sides by 9
∴ k = 0.4
∴ The scale factor is 0.4
The scale factor which used to perform the dilation was 0.4

The copy machine makes 105 copies per minutes.
Step-by-step explanation:
Given,
Copies printed by photocopy machine = 735
Time taken by machine = 7 minutes
To find the unit rate in terms of minutes, we will divide the copies printed by machine by the time taken.
Copies printed in one minute = 
Copies printed in one minute = 105 copies
The copy machine makes 105 copies per minutes.
