15. The answer that best fits the question would be the "First" option. the ( and ) are just things to say do the inner work first, then multiply.

16. The Third option is the answer that best fits the question. She is trying to find how many time she did something, so multiplication would be the answer.

Hope this helps!

Solve this system of equation using the substitution method<br><br> 2x + y = 5<br><br> y = x - 4

Amanda [17]

Answer:

$\boxed {\boxed {\sf (3, -1)}}$

Step-by-step explanation:

We are asked to solve this system of equations using substitution:

$2x+y=5\\y=x-4$

Since y is equal to x-4, we can substitute x-4 in the top equation.

$2x+(x-4)=5$

$2x+x-4=5$

Combine the like terms on the left side of the equation. 2x and x both have the variable x and can be added.

$3x-4=5$

Now, solve for x by isolating the variable. 4 is being subtracted and the inverse of subtraction is addition. Add 4 to both sides.

$3x-4+4=5+4\\3x=5+4\\3x=9$

x is being multiplied by 3 and the inverse of multiplication is division. Divide both sides by 3.

$3x/3=9/3 \\x=9/3 \\x=3$

x is equal to 3. Substitute 3 back into the bottom equation to find y.

$y=x-4\\y=3-4\\y=-1$

Points are written as (x,y). The solution to this system of equations is (3, -1).

Given ƒ(x) = 3x + 9, find x when ƒ(x) = 21. <br><br> A) 3 <br> B) 4 <br> C) 7 <br> D) 10

Alborosie

Answer:

B

Step-by-step explanation:

Replacing <em>f</em>(x) with 21, this is the equation

21=3x+9

First, subtract 9 from each side of the equation to get:

12 = 3x

Next, divide each side by 3 to get:

4 = x

So the answer is B.
