Answer:

-4y - 7x^3 + 2

Step-by-step explanation:

So first lets combine the y terms together, doing this we get:

-4y + 1 - x^3 - 3x^3 + 1 - 3x^3

Now lets combine the terms with x^3 together

-4y + 1 - 7x^3 + 1

Lastly, lets add the constants

-4y - 7x^3 + 2

x = 375 and y = 6300. Option C.

Step-by-step explanation:

From the given data we need to find the value of x and y.

First, we will find out the ratio of area and the force.

$\frac{Area}{Force} = \frac{125}{1875} =\frac{150}{2250} =\frac{175}{2625}$ = $\frac{1}{15}$

So,

$\frac{x}{5625} = \frac{1}{15}$

or, x = $\frac{5625}{15}$ = 375

Again,

$\frac{420}{y} = \frac{1}{15}$

or, y = 420×15 = 6300

Hence,

x = 375 and y = 6300.

“Your salary is $25,000 and you will be receiving a 2.5% pay increase this year. What will your new salary be?”

Naddika [18.5K]

If your current salary is the 100%, and you get a 2.5% increase, that means the new salary would be 102.5% of 25,000. This percentage could also be written as 1.025, which you would multiply to 25,000 to get your new salary.

1.025 · 25,000 = 25,625

Therefore, your new salary would be $25,625
