Y=mx+b

First use the two point slope formula to find m

(y2-y1)/(x2-x1)
(2-0)/(-9-9)
2/-18
1/-9=m

Next use the point slope formula to find the answer

y-y1=m(x-x1)

y-0=1/-9(x-9)

Now use Distributive Property
y-0=1/-9(x)+1/-9(-9)
y-0=1/-9x+1

Your answer would be
y=-1/9x+1

Answer:

48 grams

Step-by-step explanation:

pretzels : peanuts : cheese sticks

8 : 5 : 1

64 g : ? g : ? g

grams of peanuts = 5*64 / 8 = 40 g

grams of cheese sticks = 64*1 /8 = 8 g

<u>grams of peanuts and cheese sticks</u> = 40 + 8 = 48 grams

X+8=-15 help again sorryyy

suter [353]

X by its self is always 1x

1x+8=-15 you have to get rid of 8 by subtracting on both sides

1x=-23 now get rid of 1 by dividing on both sides

x=-23

For the parent function y=√x what effect does a value of b = -2 have on the graph?

Jobisdone [24]

We have no idea how 'b' is related to the parent function, or to the graph,
or to anything else, so no answer is possible. From just the information
given in the question, 'b' has no effect whatsoever on the graph, or on
how much rain Chicago will get next week.or on how much my dog will
eat tonight.

Given f(x), find g(x) and h(x) such that f(x) = g(h(x)) and neither g(x) nor h(x) is solely x.

aniked [119]

Answer:

Please look at the different answers. I wasn't 100% sure what your expression was.

Step-by-step explanation:

If you mean 2/(5x-1) then g(x) will take the fraction into account with a constant 2 for the numerator and a variable for the denominator since that is where our variable is so g(x)=2/x.

Now h(x)=5x-1 since if you plug in 5x-1 into 2/x where x is you will get our original expression.

Now if you did mean (2/5)x-1 I would take notice of where the variable is which is in (2/5)x so g(x)=x-1 where h(x)=(2/5)x since if you plug (2/5)x in place of the x in x-1 you will get the original.

Please let me know if I didn't interpret your expression correctly.
