Answer: y = 2x

Step-by-step explanation:

y=mx+b

m is the slope. so if the slope is 2 we can fill in 2 for m.

y = 2x + b

now we are going to plug in the point they gave us (1, 2) to find b.

1 is the x coordinate of the point and 2 is the y coordinate. so we put 1 in for x and 2 in for y.

2 = 2(1) + b

2 = 2 + b

b = 0

so our equation is y = 2x + 0, or y = 2x

Which best explains whether point G can be the centroid?

wariber [46]

The answer is C.

FG = 6
FC = 18
so
GC = 12

12:6 = 2:1

rewrite f(x)=x^2+8x-20 in the form that would most easily help you identify the zeros of the function

Snowcat [4.5K]

Answer:

f(x) = (x-2) (x+10)

Step-by-step explanation:

f(x)=x^2+8x-20

Factor the right hand side

What 2 numbers multiply to -20 and add to 8

-2 * 10 = -20

-2 + 10 = 8

f(x) = (x-2) (x+10)

Then we can use the zero product property to help us to find the zero's
