Answer:

y=3/2x+3

Step-by-step explanation:

The equation is in y=mx+b format. m is the slope, or steepness of the line, while b is the y intercept (where the line crosses with the y axis).

The given line shows the y intercept; it's 3.

To find the slope, use this equation: y2-y1/x2-x1

Pick any two points and plug them into the equation. For example, use (0,3) (y intercept) and (-2, 0) (x intercept.)

now,

3-0/0-(-2)

3/2

the slope is 3/2.

Now, the line is

y=3/2x+3.

Step-by-step explanation:

since overtime is 1/2 the usual pay which is 8.25 or 8 1/4 then its 8 1/4 (divided) by 1/2 which is equal to 4.125 or 4 1/8 so: in 1 hour the workers get paid 4 1/8 dollars and in 8 hours its 8 x 4 1/8 which is equal to 33

    really hope this helps :) good luck

#Answer:

1 hour = $4.13 (rounded) . 1 hour = $4.125 (not rounded)

8 hours = $33.04 (rounded) 8 hours = $33 (not rounded)

Answer:

m=1/2

Step-by-step explanation:

When finding the slope of a line on a graph, I like to count the steps up/down and to the side between two of the line's points. For this line, we can see that it has points at (2,-1) and (4,0). To get from (2,-1) to (4,0), you need to count

"up 1, over 2"

1/2

Therefore, the slope is 1/2.

Answer:

G=32 I think,

Step-by-step explanation:

Hope it helps

Answer:

G = 32

Step-by-step explanation:

To do this problem, we first should rewrite the problem.

g + (-5) =27

Turns into

g - 5 = 27.

Then you can do the problem:

g - 5 = 27

 + 5   + 5

----------------

g = 32

Answer:

A

Step-by-step explanation:

This is a hopeless question. The best anyone can do is guess.

The only one that is completely wrong is C. It says that the more you watch TV the less snacks you eat. Not what the premise says.

D oddly enough could be. You might reach a pinacle and not want anything more. I don't think it is the intended answer, but it is possible.

B is hard to eliminate as well. There might not be any relationship at all or a very weak one. I think it should be eliminated because it most resembles C.

The answer is A. I think this is what you are intended to answer.

Answer:

30

Step-by-step explanation:

To find the determinant of a 3x3 matrix, you can use this method. (See picture.)

Start with the first number in the top row, and block off the row and column.  A 2x2 matrix will be left.  Find the determinant of this 2x2 matrix, and multiply it by the number in the top row.

Repeat for the other two numbers in the top row.  Add the first result, subtract the second, and add the third.

det A = -2 [(3)(-5) − (a)(0)] − 2 [(0)(-5) − (a)(0)] + b [(0)(0) − (3)(0)]

det A = -2 (3)(-5) − 0 + 0

det A = 30

Answer:

30

Step-by-step explanation:

x = 2, y = 7 and z = 6

so 4(x + y) —z = 4(2+7) - 6

= 4(9) - 6

= 36 -6

= 30

Answer – 7 years old

SOLVINGS

Let Kevin’s present age be ‘x’

In 56 years, Kevin’s age will be x + 56

In 56 years, Kevin’s age will be 9x

Therefore, x + 56 = 9x

Solving for x

x + 56 = 9x

9x – x = 56

8x = 56

x = 56/8

x = 7

The given question is incomplete

Here are some letters and what they represent. All costs are in dollars.

m represents the cost of a main dish.

n represents the number of side dishes.

s represents the cost of a side dish.

t represents the total cost of a meal.

Discuss with a partner: What does each equation mean in this situation? a. a.  m = 7.50

b. m = s + 4.50

c . ns = 6

d. m + ns = t

2. Write a new equation that could be true in this situation.

Answer:

t = 3m -n(s+1)

Step-by-step explanation:

Using the information we can describe the value of each letters

using a and b

        7.50 = s + 4.50

         s = 3

substitute s in c, we get

using equation d we have

so we an equation using the above data

t +ns = 3m - n

t = 3m -n(s+1)

The correct question is

Zena needs a salesperson. Salesperson A is offering his services for an initial $50 in addition to $5 per hour. salesperson B is offering her services for an initial $40 in addition to $7 per hour. When will the two coaches charge the same amount of money?

Let

x ----> the number of hours

y ----> the total charge

we know that

Salesperson A

------> equation A

Salesperson B

------> equation B

To find out when the two coaches charge the same amount of money, equate equation A and equation B and solve for x

7x+40=5x+50

7x-5x=50-40

2x=10

Step-by-step explanation:

i just did it on edg

The value of each coin (Nickels and Quarters) determines their number in a money sum

The correct option that gives the equation that can be used to solve for the number of nickels, n, is option;

0.05·n + 0.25·(36 - n) = 6

Reason:

The given equation can be presented as follows;

[tex]\begin{array}{|c|c|c|c|}&\mathbf{Number}&\mathbf{Value}&\mathbf{Total \ value}\\&&&\\Nickels&n&0.05&0.05 \cdot n\\Quarters&36 - n&0.25 & 0.25 \cdot(36 - n)\\&&&\\\mathbf{Total}&36&&6\end{array}\right][/tex]

From the above table, we have;

0.05·n + 0.25·(36 - n) = 6

Solving the above equation gives;

0.05·n + 9 - 0.25·n = 6

-0.2·n = 6 - 9 = -3

[tex]n = \dfrac{3}{0.2} = 15[/tex]

Therefore;

The equation that can be used to solve for the number of nickels, n, is; 0.05·n + 0.25·(36 - n) = 6

Step-by-step explanation:

Let x represent Ben's weight gain.

[tex]138 \geq 133 + x\\[/tex]

Subtract 133 from both sides

[tex]5 \geq x[/tex]

Therefore, Ben can't gain more than 5 points if he wishes to stay in the same weight class.

Answer:

[tex]x\geq -\frac{15}{2}[/tex]

Step-by-step explanation:

add 4 on both sides

leaves you with 15 on the right side

you then divide by negative 2

since you divide by a negative you have to switch the sign

Isolate the variable by dividing each side by factors that don't contain the variable.
