The equation 201.50=f+6.50(21) represents the cost of printing the shirts at a second printing company. Find the solution to the

AveGali [126]

Answer:

f = 65

Setup cost = 65

Step-by-step explanation:

Given the equation : 201.50=f+6.50(21)

Solving for f:

201.50 = f + 136.50

201.50 - 136.50 = f

f = 65

The equation above is written in the form a slope intercept function where,, 6.50 is the gradient and X equals the number of shirts, The total cost of printing is 201.50

f is the intercept and represents the initial fee or setup cost. Hence, the setup. Cost = 65

What does the line y=-2x+5 look like?

Usimov [2.4K]

$\huge{\boxed{\text{D}}}$

This line is in the format $y=mx+b$ , where $m$ is the slope.

A horizontal line has a slope of $0$ .

A vertical line has an undefined slope.

A positive slope makes the line go upwards and to the right.

A negative slope makes the line go downwards and to the right.

Maggie needs to spend at least six hours each week practicing the piano. She has already practiced three and one fourth hours th

vfiekz [6]

Answer:

three and one fourth + 2x ≥ 6

Step-by-step explanation:

Let

x -----> the minimum number of hours he needs to practice on each of the two days

we know that

needs to spend at least seven hours each week practicing the drums

$3\frac{1}{4}+2x\geq 6\ hours$

Convert mixed number to an improper fraction

$3\frac{1}{4}\ hours=\frac{3*4+1}{4}=\frac{13}{4}\ hours$

substitute

$\frac{13}{4}+2x\geq 6\ hours$

Subtract 13/4 both sides

$2x\geq 6-\frac{13}{4}$

$2x\geq \frac{11}{4}$

Divide by 2 both sides

$x\geq \frac{11}{8}$

therefore

The minimum number of hours he needs to practice on each of the two days is $\frac{11}{8}\ hours$
