Answer:

this is a percent of change increase.

Step-by-step explanation:

you want to use the formula,

new value - original value

____________________

        original value               * 100

now that we wrote the formula down, you substitute the numbers in. 2 is the original value and 4 is the new value.

4 - 2

____

  2   * 100

2

_

2 * 100

now that we find the amount of change, we could do this in two ways. divide the fraction first then multiply that by 100 OR multiply the numerator by 100 first then divide that by the denominator.

first way :

2

_

2  * 100

1 * 100 = 100% increase

second way :

2

_

2  * 100

200

___

 2  = 100% increase

What is the equation of the line that passes through (-5, 7) and is parallel to the line y = 4x + 5?
Marysya12 [62]

Answer:

y=4x+27

Step-by-step explanation:

If a line is parallel, it would have the same slope, so you already have that.

Now, you need the y-intercept of the second line. You already have one point, so use that point and the slope to find the y-int. What you can do (since you know you have to go up 4 and over 1, add a 1 to the -5 until you get to zero. your y-int would be 7+20 since you've gone up 5x4)

your final answer (i think) should be y=4x+27, but I could be wrong :))

Leni [432]

Answer:

She worked 18 hours of overtime.

Step-by-step explanation:

If she works 40 hours per week and gets $200, subtract $380 - $200 = $180.

If you multiply $180 by 0.1 (which is 10% converted to a decimal), you get 18 which is your final answer.
