GCF of 20 and 8 is 4

4(5z - 2)

Sliva [168]3 years ago

Answer:

20z−8=4(5z-2)

Step-by-step explanation:

20z−8

20z can be written as 5 times 2 times 2 times z

8 can be written as 2 times 2 times 2

20z-8= 5 \cdot 2 \cdot 2 \cdot z- 2 \cdot 2 \cdot 2

Greatest common factor for 20z  and 8 is 2 times 2 = 4

Now take out 4 in common

20z−8=4(5z-2)

1. Identify the vertex and the y-intercept of the graph of the function y=-2(x+ 2)+2.
KATRIN_1 [288]

Answer:

Please let me know if your quadratic is y=-2(x+2)^2+2.

And if so your vertex is (-2,2) and your y-intercept is (0,-6)

Step-by-step explanation:

It says vertex so I'm thinking you meant y=-2(x+2)^2+2.  Please correct me if I'm wrong.

The vertex form of a quadratic is y=a(x-h)^2+k.  It is called that because it tells you the vertex (h,k).

So if you compare the two forms you should see -h=2 while k=2.

-h=2 implies h=-2.

So the vertex is (h,k)=(-2,2).

To find the y-intercept, set x=0 and find y.

y=-2(0+2)^2+2

y=-2(2)^2+2

y=-2(4)+2

y=-8+2

y=-6

So the y-intercept is (0,-6).

Solve the equation below.<br> 3(17x – 6.5) = 108
olga_2 [115]

Answer:

x=2.5

Step-by-step explanation:

3(17x – 6.5) = 108

Divide each side by 3

3/3(17x – 6.5) = 108/3

17x - 6.5 =36

Add 6.5 to each side

17x -6.5+6.5=36+6.5

17x = 42.5

Divide each side by 17

17x/17 = 42.5/17

x = 2.5
