Answer:5x+9-(2x+7+3x-15)=0

We add all the numbers together, and all the variables

5x-(5x-8)+9=0

We get rid of parentheses

5x-5x+8+9=0

We add all the numbers together, and all the variables

17!=0

There is no solution for this equation

Answer:

No Solutions

Step-by-step explanation:

Step 1:

5x + 9 = 2x + 7 + 3x - 15 Equation

Step 2:

5x + 9 = 5x - 8 Add and Subtract

Step 3:

9 = - 8 Subtract 5x on both sides

Answer:

9 ≠ - 8 9 cannot equal - 8

Describe the transformation that takes f(x)=x+1 to g(x) = -x+4. Will Mark Brainliest.

Answer:

Reflection across y axis

Translate up by 3 units

Step-by-step explanation:

Given

$f(x) = x + 1$

$g(x) = -x + 4$

Required

Describe the transformation from f(x) to g(x)

First, take a reflection of f(x) across the y axis.

So f(x) becomes f(-x)

$f(x) = x + 1$ when reflected

$f(-x) = -x +1$

Next, translate f(-x) up by 3 units to give g(x)

$g(x) = f(-x) + k$

Where

$k = 3$

$f(-x) = -x +1$

$g(x) = -x + 1 + 3$

$g(x) = -x + 4$

Hence, the transformation from f(x) to g(x) includes:

Reflection across y axis

Translate up by 3 units

At the beginning of football season, Coach Carnes takes inventory of the team equipment to see what he needs. He counts 24 footb

Leviafan [203]

Answer:

Step-by-step explanation:

To solve this, lets first find the number of footballs he still needs:

75-24 = 51

Now to find the number of packages, divide by 4, since there are 4 balls per package:

51/4 = 12 Remainder 3

Since there is a remainder, and the Coach MUST have at least 75, then we need to add a package to include the remainder:

12 + 1 = 13 Packages
