When Kim works 40 hours in a week, she earns $560. If she works only 35 hours, how much should she expect to earn?

9514 1404 393

Answer:

  a) 10(3x+2) ≤ 140; x ≤ 4

  b) no

Step-by-step explanation:

a) The area is the product of length and width. We want that product to be no greater than 140:

  10(3x +2) ≤ 140 . . . . your inequality

We can solve this by dividing by 10 first.

  3x +2 ≤ 14

  3x ≤ 12 . . . . . . subtract 2

  x ≤ 4 . . . . . . . . divide by 3; the solution to the inequality

__

b) If the length were 15, the area would be 10×15 = 150, which is greater than 140. The length cannot be 15 if the area is at most 140.

Answer:

£12083.52

Step-by-step explanation:

Given amount:

      Amount  = £14132.77

Percentage decrease = 14.5%

Solution:

To decrease the given amount by 14.5% implies multiply it by:

                [tex]\frac{100-14.5}{100}[/tex]  = 0.855

Now;

      Decreased amount  = £14132.77  x 0.855

      Decreased amount  = £12083.52

Answer:

1) (1,4)

Step-by-step explanation:

Translation is a type of transformation that moves every point in an object the same distance in the same direction.

The object is A (-1,3)

The translation is T(2,1)

Applying the translation will be;

A (-1,3) ---------- A' { -1 +2 , 3+1}  = { 1 ,4}

A' = (1,4)

Answer: The answer is D. the data distribution is skewed to the right.

Step-by-step explanation:

Since in the picture it is shown that everything is more to the left but the tail is on the right side so it would be skewed right.

Slope Intercept form = Y = mx + b

Answer:

[tex]y=2x+5[/tex]

Step-by-step explanation:

The original equation is [tex]y=mx+b[/tex]

Step 1: Define your variables.

In this case they are:

m=2 and x=5

Step 2: Plug in the variables.

I will do this step by step

[tex]y=mx+b\\y=2x+b\\y=2x+5[/tex]

And there you have it the equation for Slope Intercept Form.

I hope this helps.

Answer:

5. The slope is 1 and y intercept is -2 points to graph (0,-2) (1,-1)

6. The slope is 1/2 and y intercept is 3 points to graph (0,3) (1,4)

Step-by-step explanation:

Answer:

4/5 is the slope.

Answer:

0

Step-by-step explanation:

When a problem asks for the value of f(x), find the y value for the given x value. In this instance, since x = 8, y = 0.  

From the graph the value of f(8) is 0.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

From the graph we have to find f(8)

This shows that the values of function at x=8

Now, focusing on the x- axis we have keep point on x= 8 then move and where the line touches the functional line we get the result.

Hence, from the graph the value of f(8) is 0.

Answer:

t = [tex]\sqrt{\frac{-2(h-1)}{a} }[/tex]

Step-by-step explanation:

solve for t

h = -[tex]\frac{1}{2}[/tex]a[tex]t^{2}[/tex] + 1; multiply both sides by -2

-2h = a[tex]t^{2}[/tex] - 2; add 2 to both sides

-2h + 2 = a[tex]t^{2}[/tex]; divide by a

(-2h + 2) / a = [tex]t^{2}[/tex] ; take the square root

t = [tex]\sqrt{\frac{-2(h-1)}{a} }[/tex]

The first step is to use the Subtraction property of equality to combine the constant terms. Thus;

72 - 2x - 72 = 11 - 72

-2x = -61

The second step is to use the Division property of equality to isolate the variable to get;

-2x/-2 = -61/-2

Answer:

y=x+5

Step-by-step explanation:

You can tell by looking at the sequence that each number is five more than the previous. With that in mind, you know that, to find the next number in the sequence, you have to add five to the one before it.

Making x the previous number and y the next number in the sequence, you get the equation y=x+5

You can plug pairs from the sequence to check:

2= -3+5

2=2

7= 2+5

7=7
