Answer:

x=2

Step-by-step explanation:

First. 7x+15−12x=12x+5−12x

−5x+15=5

Then subtract 15 from both sides

−5x+15−15=5−15

−5x=−10

After that divide both sides by -5 .

−5x

−5

−10

−5

x=2

Alecsey [184]

She would make $573.5 in a work if she sold $4,700 worth of merchandise

Step-by-step explanation:

The given is:

Mae Ling earns a weekly salary of $315 plus a 5.5% commission on sales at a gift shop
She sold by $4,700

We need to find how much she would make in a work week

∵ Mae Ling earns a weekly salary of $315

∵ She earns a 5.5% commission on sales

∵ She sold by $4,700 in that week

- Add $315 to the product of 5.5% and $4,700

∴ She made = 315 + (5.5% × 4,700)

∵ 5.5% = 5.5 ÷ 100 = 0.055

∴ She made = 315 + (0.055 × 4,700)

∴ She made = 315 + 258.5

∴ She made = 573.5

She would make $573.5 in a work if she sold $4,700 worth of merchandise

A T-shirt design company charges your team an initial fee of $25 to create the team's design. Each T-shirt printed with your des

Korvikt [17]

Answer:

Part A)

$C(t)=25+8t$

Part B)

$C(35)=\$305$

Step-by-step explanation:

We will let t represent the total number of t-shirts printed.

We are charged an initial fee of $25. So, for our linear model, our constant is 25. And each t-shirt printed costs an additional $8. So, for t t-shirts, it will cost an additional 8t dollars.

Part A)

So, from the above information, we can write the following function:

$C(t)=25+8t$

Where C(t) is the total cost for t shirts.

The 25 represents our initial fee and the 8t represents the cost for t t-shirts.

Part B)

So, if we have a team of 35 members, we will need 35 t-shirts.

Then the total cost will be given by:

$\begin{aligned}C(35)&=25+8(35)\\&=25+280\\&=\$305\end{aligned}$

So, it will cost a total of $305.

Anyone knows what’s is the answer for 5 ?

Andreas93 [3]

Answer:

f(x) = |x - 4| + 3

Step-by-step explanation:

Identify (from the graph) the coordinates of the vertex: (4, 3). That +4 tells us that the vertex of the basic function y = |x| has been translated 4 units to the right; that +3 tells us that the vertex has also been translated 3 units up. Consider y = |x-a| + b. Here, b = +3 and a=+4. Thus, the correct function is f(x) = |x - 4| + 3.
