Complete the equations of the line through (-9,7) and (-6,-3)
lbvjy [14]
In point slope form, the equation is y-7=(-10/3)(x+9).  In slope-intercept form, it is y=(-10/3)x-23.

First find the slope of the line.  The formula for slope is
m=(y₂-y₁)/(x₂-x₁)

Using our points, we have 
m=(-3-7)/(-6--9) = -10/3

Plug this into point slope form:
y-y₁=m(x-x₁)
y-7=(-10/3)(x--9)
y-7=(-10/3)(x+9)

Using the distributive property:
y-7=(-10/3)*x+(-10/3)*9
y-7=(-10/3)x-90/3
y-7=(-10/3)x-30

Add 7 to both sides:
y=(-10/3)x-23

=Given that f(x) = -22 +1 and g(x) =(f +9) (0)2find:2+1'7O 3O 2O undefined, you can't put a 0 in the denominatorO-3
Tasya [4]

f(x) = -x^2 +1

g(x) = 2 / (x+1)

Find (f+g) (0)

We can find f(0) + g(0)

f(0) = -0^2 +1 = 1

g(0) = 2/(0+1) = 2/1 = 2

f(0) + g(0) = 1+2 = 3

Why is 6/8 greater than 5/8 but less than 7/8?
Phoenix [80]
Because if you draw a three pies and cut all of them into 8 pieces and shade 6 in one, 5 in the other, and 7 into the last one, you will see that there is a bigger piece shaded in the one with 6 shaded than the pie with 5 shaded. And less shaded than the one with 7 shaded. Hope I helped :)
