Answer:

x = 0

Step-by-step explanation:

(x)=5x+19(x)=-2x+15

We move all terms to the left:

(x)-(5x+19(x))=0

We add all the numbers together, and all the variables

x-(+24x)=0

We get rid of parentheses

x-24x=0

We add all the numbers together, and all the variables

-23x=0

x=0/-23

x=0

Answer:

B. $f^{-1}(x)=\frac{x-4}{5}$

Step-by-step explanation:

To find the inverse of a function/equation:

Replace f(x) with y: y=5x+4
Switch x and y: x=5y+4
Solve for y: x-4=5y -> $y=\frac{x-4}{5}$
Write in standard inverse notation: $f^{-1}(x)=\frac{x-4}{5}$

I hope this helps!!

*IGNORE THE ANSWERS* This is 2nd grade math. I forgot how to solve these equations. Help:)

Mazyrski [523]

Answer:

a. 14

b. 7

Step-by-step explanation:

a. First we must add all the animals together,

Total Animals:

Birds: 6

Fish: 5

Mammals: 11

Reptiles: 3

Therefore our equation is:

6 + 5 + 11 +3 = 25.

Now, we must subtract by the number of mammals:

25 - 11 = 14

So our answer for a. is 14!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

b. So for this problem we must compute mammals + fish and than birds + reptiles. After we figure that out we must subtract them!

Mammals + Fish =

11 + 5 =

Next,

Birds + Reptiles =

6 + 3 =

Now, let us subtract them,

16 - 9 =

So our answer for b. is 7 more animals!
