Answer:

$171

Step-by-step explanation:

(6+13)x9=

19x9=

171

Answer:

The answer is X=171

Step-by-step explanation:

9(6+13)=X

you use the distributive property

9x6+9x13=X

then you do

9x6 which is 54

54+9x13=X

then you do 9x13 which is 117

54+117=X

then you add it which equals 171

X=171

Answer:

[tex]\frac{1}{2}[/tex]h

Step-by-step explanation:

Let the total batch of cookies be x.

[tex]\frac{3}{5}[/tex]x = [tex]\frac{3}{10}[/tex]h

[tex]\frac{5}{5}[/tex]x = [tex]\frac{5}{3}[/tex] × [tex]\frac{3}{10}[/tex]h

x = [tex]\frac{15}{30}[/tex]h

x = [tex]\frac{1}{2}[/tex]h

Answer: No

Step-by-step explanation:

The domain consists of the numbers 6, 5, 6, 2

6 is repeated twice

The criteria for a function is that there are no repeating numbers in the domain

This does not follow the criteria, therefore this is not a function

Answer-No

Answer:

$246.75

Step-by-step explanation:

A student earns $11.75 for 1 hour

If she works for 21 hours this month then the total amount earned can be calculated as follows

= 11.75 × 21

= 246.75

Hence the total amount earned this month is $246.75

Answer:

yes i used a calculator for the last one

Answer:

A. The explanation of the rules are;

For the job offer for the Evergreen Landscape, Blake will have 9.75 times by the number of hours worked less the $25 for gas at the end of the week

For the job offer for the Just Jean, Blake will have 6.50 multiplied by the number of hours worked less the $5 for gas at the end of the week

B. The solution to the equations is that the number of hours Blake will work to have the same amount in both Jobs is 6.1538 hours

C. Blake should take the Job at Evergreen Landscape

Step-by-step explanation:

The amount Evergreen Landscape will pay Blake to mow lawn = $9.75

The amount Blake would spend to work per week on gas for work at Evergreen Landscape = $25

The amount Just Jean will pay Blake to work per week as a retail clerk = $6.50

The amount Blake would spend to work per week on gas for work at Just Jean = $5

Whereby, x = The number of hours that Blake will work in a week

y = The amount of money he will have end of the week, if he does not spend any money except gas

A. The given rules are;

y = 9.75·x - 25

y = 6.50·x - 5

For the job offer for the Evergreen Landscape, we have;

y = 9.75·x - 25

Blake has to put aside $25 out of his weekly earnings for gas

Blake will have 9.75 multiplied by the number of hours worked less the $25 for gas

For the job offer for the Just Jean, we have;

y = 6.50·x - 5

Blake will have 6.50 multiplied by the number of hours worked less the $5 for gas

B. The common solution of the both equations is given by equating both values of y as follows;

9.75·x - 25 = 6.50·x - 5

9.75·x - 6.50·x = 25 - 5

3.25·x = 20

x = 20/3.25 = 6.15385

x = 6.15385

The number of hours Blake will work to have the same amount in both Jobs = 6.1538 hours

C. Given that the number of hours Blake can work each week = 15 hours, we have;

For the job offer for the Evergreen Landscape, we have;

y = 9.75 × 15 - 25 = 121.25

The amount of money he will have end of the week = y = $121.5

y = 6.50 × 15 - 5 = 92.5

The amount of money he will have end of the week = y = $92.5

Therefore, given that by working 15 hours a week, Blake earns $121.5 on the Evergreen Landscape job and $92.5 on the Just Jean job, Blake should take the Job at Evergreen Landscape.

Step-by-step explanation:

Line parallel to the line y = -2/3 x + 8 also has the slope -2/3.

Since the line passes through (4, -5), we have (x - 4) written on the right side and (y + 5) on the left side.

Hence the equation is y + 5 = -2/3 * (x - 4). (B)

Answer:

Add up all the sides.

Step-by-step explanation:

Add up all the sides.

Add up all the sides of the triangle that is the perimeter.

Hope this helps plz hit the crown :D

Answer:

The slope of a line is change in Y / change in X. The slope of a horizontal line = 0, not undefined. The slope of a vertical line = undefined.

the slope of a virtual lin.e is change in Y / change in X

Answer:

[tex]x= \frac{-7+\sqrt{697}}{8}[/tex]

[tex]x= -\frac{7+\sqrt{697}}{8}[/tex]

Step-by-step explanation:

4(x+3)-4 = 81/2x +1

Add 4 to both sides

4(x+3) = 81/2x +5

Multiply both sides by 2x (This removes the division from the second half)

8x(x+3) = 81 +10x

Simplify

[tex]8x^{2}[/tex]+24x = 81 +10x

Subtract 10x from both sides

[tex]8x^{2}[/tex] +14x = 81

Subract 81 from both sides

[tex]8x^{2}[/tex] +14x -81 = 0

Solve using the quadratic formula

[tex]x= \frac{-b (+-) \sqrt{b^{2} -4ac}}{2a}[/tex]

a= 8, b= 14, c= -81

[tex]x = \frac{-14 (+-) \sqrt{14^{2} -4 *8(-81)} }{2*8}[/tex]  

Simplify

[tex]\sqrt{14^{2} -4 *8(-81)} = 2\sqrt{967}[/tex]

[tex]\frac{-14 (+-) 2\sqrt{967}}{2*8}[/tex]

Simplified Solution

[tex]x= \frac{-7+\sqrt{697}}{8}[/tex]

And

[tex]x=- \frac{7+\sqrt{697}}{8}[/tex]

I know this is confusing but I hope it helps. Keep in mind that (+-) means plus or minus. You might also look up what the quadratic formula is if you are not already familiar with it.

Answer:

Area = a²

Step-by-step explanation:

For a square, all 4 sides are equal. If a be the side of a square and A be its area. Then, the area of a square is given by :

Area = side²

or

Area = a²

Hence, the area of a square is square of the length of its side.
