I need to sketch a graph for each line. y = 4x-5 How would I solve and graph this

So you need to find the slope and the y- intercept. So, the slope is always the coefficient on the x. In this case it is 4. The y-intercept is the other number. In this case it is -5. So the slope is 4 and the y-intercept is -5. On your graph (the y axis) find -5. Then you go up 4 and to the right 1 because of four were a fraction it would be 4/1. Keep going up four and right one a couple times. Then reverse it. Go down 4 left 1. That as a fraction would look like -4/-1. Then connect your points and make it a line!

Violet contributes 12% of her $55,700 annual salary to her 401(k) plan. What is her pretax income?

NikAS [45]

You have that:

- Her contribution from her salary to her 401(k) plan, is: 12%.
- Her annual salary is: $55,700.

Then, to solve this problem and calculate her pretax income, you must following the steps below:

1. You must calculate the amount that Violet contributed to her 401(k) plan. So, you have:

12%/100=0.12

($55,700x0.12)=$6,684

2. Now, you must subtract her annual pay ($55,700) by the amount obtained ($6,684), as below:

Pretax income= $55,700-$6,684
 Pretax income=$49,016

What is her pretax income?

The answer is: Her pretax income is $49,016

Answer:

$445$

Step-by-step explanation:

$\text{Profit}=\text{Price}-\text{Cost}\\\text{Profit}=2.75-50=2.25\\\text{In order to make back the starting amount we need to sell n lots of widgets.}\\2.25n\geq 1000\\n\geq \frac{1000}{2.25}\\n\geq 444.444444\\\text{You can't sell a fraction of products, so you need to round it up to the nearest number.}\\n=445$
