Answer:

C. y = -2x - 1

Step-by-step explanation:

y = mx + b

The slope is going down so that means that the m will be negative.

We are left with two choices:

y = -2x - 1

y = -2x + 1

Check the graph again to find what point does the line intersect the vertical line (y-axis). That hits in (0, -1) or -1.

So the only answer applicable is option C.

Factor by using the perfect-square trinomial formula. <br><br> 100x^2+20x+1

a_sh-v [17]

To factor first multily 100 and 1 and get 100

then find what 2 numbers multiply to get 100 and add to get 20

the numbers are 10 and 10

so
split the center term up
100x^2+10x+10x+1
group
(100x^2+10x)+(10x+1)
undistribute
(10x)(10x+1)+(1)(10x+1)
undistribute/reverse distributive property
(10x+1)(10x+1)
(10x+1)^2
