Answer: (3x + 4y)(3x + 4y)

Step-by-step explanation: So you are supposed to "unfoil". So you would find two numbers multiplied together to make 9x^2 which would be 3x. Then you would find two numbers that can be multiplied together to get 16y^2 which would be 4y. To check your work, you do 3x times 3x. Then 4y times 4y. Then 4y times 3x plus 3x times 4y. You get 9x^2 + 24xy plus 16y^2.

You are an hourly-paid employee who is paid on a weekly basis. You are making $23.13 per hour and work 40 hours per week. Taxes

Contact [7]

Answer:

578.13

Step-by-step explanation:

40hrs at 23.13 is 925.20

Federal 22% = 203.54

FICA 7.65% = 70.77

Sate 3% = 27.76

Subtract those taxes from the 925.20 and round the penny fractions up (.235 = .24) and you get 623.13 but then don't forget about your 401k retirement plan, 45$ every week, so subtract that and then you're 1k a week paycheck, which is really nice btw, is down to................ 578.13!!!!!!

The point-slope form of the equation of the line that passes through (–5, –1) and (10, –7) is . What is the standard form of the

kvasek [131]

Answer:

Point-Slope form: $y+1=-\frac{6}{15}(x+5)\\$

standard form: $2x+5y=-15$

Step-by-step explanation:

The standard form is given by: $Ax+By=C$

The point-slope form is given by: $y-y_1=m(x-x_1)$

Let's call $(-5,-1)$ as point $(x_1,y_1)$ , and

point $(10,-7)$ as point $(x_2,y_2)$

We also know that the slope $m$ is given by $m=\frac{y_2-y_1}{x_2-x_1}$

Let's find the slope:

$m=\frac{-7-(-1)}{10-(-5)}=-\frac{6}{15}$

1. So, point slope form can be written as:

$y-(-1)=-\frac{6}{15}(x-(-5))\\y+1=-\frac{6}{15}(x+5)\\$

2. Rearranging this equation and bringing all x's and y's to one side and the number to another side will give us the standard form. So:

$y+1=-\frac{6}{15}x-2\\y+\frac{6}{15}x=-2-1\\y+\frac{6}{15}x=-3$

But A, B, and C (standard form) needs to be integers, so to get rid of the denominator , we multiply the whole equation by 15. So we have:

$y+\frac{6}{15}x=-3\\15y+6x=-45$

We can factor out a 3, so it becomes:

$15y+6x=-45\\5y+2x=-15$

So standard form is $2x+5y=-15$

The original price of a pair of shoes is $42 the sale price is 20% off their original price what is the amount of original price

Svetlanka [38]

I am assuming ur looking for the sale price....

there are 2 ways to do this...

42 - 0.20(42) = 42 - 8.40 = 33.60 <== sale price

or

if it was 20% off, then u paid 80%...
0.80(42) = 33.60 <== sale price
