Given: 6x + 3 = 27

First what we do is to subtract 3 from both sides:

6x + 3 – 3 = 27 – 3

6x = 24

Then we divide both sides by 3:

6x/3 = 24/3

CAN SOMEONE PLEASE HELP ME!!!!
ira [324]

Answer:

A

Step-by-step explanation:

Just by looking at the graph you can eliminate some silly answers such as D and B, everything besides the slope is obvious at least:

The y int is -2

The line is negative

The standard parent function equation is just y = x with a slope of 1.

This graph is clearly a bit steeper than the normal parent function, so it has a slope that is great than -1, not less . So the only answer left is A

If you want to be sure, you can calculate the slope using rise over run and the slope should be somewhat close to -1.5 which is equal to -3/2

Thanks me later :)

H(x) = x^2+6 g(x) = 8x-5 <br><br> show that hg(x)=19 simplifies to 16x^2 - 20x + 3 = 0
Studentka2010 [4]

Answer:

h(x)=x²+6 and g(x)=8x-5

prove that hg(x)=19

Step-by-step explanation:

step 1: hog(x)=h[g(x)]

step 2: h(8x-5)

step 3: h(8x-5)= (8x-5)²+6

step 4: (8x-5)(8x-5)+6

step 5: 16x² +15x +6
