Answer:

5x + 2y + 5z

Step-by-step explanation:

Step 1: Write out expression

3x + 4y + 5z + 2x - 2y

Step 2: Combine like terms (x)

5x + 4y + 5z - 2y

Step 3: Combine like terms (y)

5x + 2y + 5z

The answer is 5x+2y+5z

That’s the answer because:
You have to combine like terms to simplify so do:
3x+2x=5x
4y+-2y=2y
5z is the only z variable
So you get
5x+2y+5z

A local boys club sold 176 bags of mulch and made a total cost of $520.They sold hardwood mulch for $3.50 per bag and pine bark

ExtremeBDS [4]

Answer:

So here is the answer.

We represent h = hardwood and p = pine bark

Here is the equation: h + p = 176

2.75p + 3.50h = 520

Next, p = 176 -h (substitute)

2.75 (176-h) + 3.5h = 520

484 -2.75h + 3.5h = 520

3.5h-2.75h = 520 -484

0.75h = 36 (divide both by 0.75)

h = 48

Therefore, the number of hardwood sold is 48.

h + p = 176

p = 176-48

p= 128

The number of pine bark sold is 128.

Hope this helps :)

Write a function G whose graph represents a vertical stretch by a factor of two followed by a translation one unit up of

expeople1 [14]

G(x)=2x+1 , vertical stretch by 2 units and shifted 1 unit up

Given :

Original function f(x)=x

To find :

Function G whose graph is a vertical stretch by 2 and move one unit up

We use the given function to for vertical stretch and shifting up

for Vertical stretch multiply the factor by f(x)

f(x) becomes 2f(x)

so the function becomes 2x

$f(x)=2f(x)=2x\\$

For moving up , we need to add the units at the end of the function

f(x)+1

2x+1

Hence, G(x)=2x+1
