-5(3v-2)+8v=5(v+5)<br> PLS HELP FAST
klio [65]

Answer:

v = -1 1/4

Step-by-step explanation:

1. -5 x -1 1/4 = 3 3/4

2. -5 x -2 = +10

3. 8 x 1 1/4 = 10

4. 5 x 1 1/4 = 6 1/4

5. 5 x 5 = 25

Now just substitute the values.

Hope that helps!

I'm new to this and I dont really understand this
agasfer [191]

Answer:

So starting off with 1a f(4)

We simply substitute x with 4 for the function

f(4)=2(4)-5

f(4)=8-5

f(4)=3

Next 1b, here it's a little different since you have to multiply the functions I think ( please correct me if I'm wrong).

gf(4), basically means functions g and f are being multiplied and their variables are being substituted with 4.

g(4)=4^2+3

g(4)=16+3

g(4)=19

and we also know from before that f(4)=3, so we'll do 19 times 3 which is 57

For the next two, I may be wrong, but I'm still going to try:

anything to the power of a negative is a fraction so for f^-1(x)=2x-5 we'll have 1/f(x)=x/2+5/2

And then for g^-1, we'll have 1/g(x)=\sqrt{x-3}  \sqrt{x-3}

Hope I helped :)

Written out numerically, it is 4x4x4. To work this out you multiply 4x4= 16 and then you have one more 4 to multiply by, so you multiply 16x4=64

Is this a proportional relationship?
Vesna [10]

Answer: yes, because it is a straight line and is on the origin and goes through the origin so it is a proportional relationship
