Answer:

[tex]f(x) = 15x - 200[/tex]

Step-by-step explanation:

Given

[tex]Earnings = \$10[/tex] per hour for 40 hours, weekly

[tex]Additional\ Hour = \$15[/tex] per hour over 40 hours, weekly

Required

Determine f(x)

From the question, we have that

x represents hours worked

Earnings in 40 hours is: 40 * 10 = $400

Hours over 40 will be: x - 40

So, earnings during this time will be: (x - 40) * 15

Total earnings is:

[tex]f(x) = 400 + (x - 40) * 15[/tex]

[tex]f(x) = 400 + 15x - 600[/tex]

[tex]f(x) = 15x - 600 + 400[/tex]

[tex]f(x) = 15x - 200[/tex]

Answer:

y-b/m = x

Step-by-step explanation:

y = mx + b

~Subtract b to both sides

y - b = mx

~Divide m to both sides

y-b/m = x

Best of Luck!

Answer:

6 . x = 24

Step-by-step explanation:

Answer:

The answer is B. Hope this helps!

Step-by-step explanation:

105 degrees is from a b to d and a b to c is 75 and 105 - 75 =30.

Answer:

30*

Step-by-step explanation:

If ABD is 105* then it would be <ABC+<CBD=105*. We know that <ABC is 75* so we can fill that in. 75*+<CBD=105*. Then we solve.

75* + <CBD = 105*

-75*                  -75*

<CBD=30*

So that's how I got it.

Answer:

X=6

Step-by-step explanation:

Well it’s already a proportion so you cross multiply

2(x)=3(4)

2x=12

Solve for X

isolate the variable by dividing 2 on both sides

x=6

X=6

Answer:

They will probably say NO

Step-by-step explanation:

Add to find the total number of response.

10 + 4 = 14

Find the probability of someone saying yes or no.

4 / 14 ≈ 0.29 or 29%

10 / 14 ≈ 0.71 or 71%

As you can see, saying NO is more likely than saying YES.

Best of Luck!

Answer:

The equation of the line is 4y = -x + 19

Step-by-step explanation:

Firstly, we need to get the slope of the line;

Since it is through two points; we have the slope as;

y2-y1/x2-x1 = (5-3)/(-1-7) = 2/-8 = -1/4

Mathematically, we can write the equation of a straight line line as;

y = mx + c

So we have;

y = -1/4x + c

y = -x/4 + c

To complete the equation, we need the value of c.

we can choose any of the points and insert the x and y value

Thus;

3 = -7/4 + c

c = 3 + 7/4

c = 19/4

So our equation becomes;

y = -x/4 + 19/4

Multiply through by 4

4y = -x + 19

Answer:

y-3= -1/4 x (x-7)

Step-by-step explanation:

Find the slope of the line between  

( 7 , 3 )  (7,3)  and  ( − 1 , 5 )  (-1,5)  using  m = y 2 − y 1 x 2 − x 1

m=y2-y1x2-x1 , which is the change of  y/ y  over the change of  x/ x .

Answer:

6

Step-by-step explanation:

3+6=9 9x7=63

Answer: 6

Step-by-step explanation:

You can set the unknown number as x and then you would add 3 to x and multiply that by 7.

The equation would be 7(x+3)=63

7(x+3)=63

7x+21=63

7x=42

x=6

The answer is 6

Step-by-step explanation:

lol sorry for this I just needed to answer one more question

Answer:

k =-2

Step-by-step explanation:

Using the slope formula

( y2-y1)/(x2-x1) = m

( k- -1)/( -10 - -8) = 1/2

( k+1)/ ( -10+8) = 1/2

( k+1) /-2 = 1/2

Multiply each side by -2

( k+1) /-2 * -2 = 1/2 * -2

k+1 = -1

Subtract 1 from each side

k+1-1 = -1-1

k = -2

Answer:

K= -5 because -10 divided by -5 which is K gives u 2

Answer:

16

Step-by-step explanation:

[tex]\sqrt{256} \\=\sqrt{16 * 16} \\=16[/tex]

Answer: 16

Step-by-step explanation: √

256=16

at least that's the positive square root

−16

is also a square root of 256.

16²=(−16)2=256

By definition, the principal square root of a number is the positive square root. The term "the square root" is commonly used to refer to the principal (positive) root though there are usually two roots.

Answer:

Step-by-step explanation:

It is helpful to realize that the exterior angle is equal to the sum of the remote interior angles:

  146° = (5y+3)° +(4y+8)°

  135 = 9y . . . . . . . . . . . . . . divide by °, subtract 11

  15 = y . . . . . . . . . divide by 9

∠abc = (4y+8)° = (4·15 +8)° = 68°

∠bac = (5y+3)° = (5·15 +3)° = 78°

∠acb = 180° -146° = 34°

Step-by-step explanation:

Answer

C

Step-by-step explanation:

Answer:

To be able to find the unit rate that each person earns for their craft, you have to divide the amount each person earns by the number of units:

Alex: $36/3=$12 per unit

Carmen: $75/5=$15 per unit

To find the amount of birdhouses that Alex will need to sell in order to make as much as Carmen does when she sells 12 scarves, first you have to determine the amount that Carmen earns when she sells 12 scarves:

$15*12=$180

Now, you need to divide $180 by the price per unit Alex earns to find the amount of birdhouses that he needs to sell:

$180/$12=15

This means that Alex needs to sell 15 birdhouses to make as much as Carmen does when she sells 12 scarves

Step-by-step explanation:

For number 3 its B because pie = irrational

Answer:

For number 2 the answer is J.

For number 3 the answer is B.

Step-by-step explanation:

2. f(x)=2x+10

f(-8)=2(-8)+10

f(-8)=(-16)+10

f(-8)= -6

3. Pi is an irrational number so 32 with pi will also be irrational.

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1) [/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (-3, -1) and slope 2

The equation is

Answer:

4 Months, and the Total amount is 280

Step-by-step explanation:

60 + 55m = ?

200 + 45m = ?

60 + 55 = 115 + 55 = 170 + 55 = 225 + 55 = 280

200 + 45 = 245 + 45 = 290 + 45 = 235 + 45 = 280
