Answer:

<h2>(5x - 4)(5x + 4)</h2>

Step-by-step explanation:

25x^2-16=5^2x^2-4^2=(5x)^2-4^2\\\\\text{use}\ a^2-b^2=(a-b)(a+b)\\\\=(5x-4)(5x+4)

A father gave his son 5/7 of his monthly allowance keeping the rest for a previous debt. The son spent 5/7 of what his father ga
lesya [120]

M = Monthly Allowance.

N = 5/7 of M (Monthly Allowance)

5/7 of 5/7 of M = 9.60

5/7 * 5/7 * M = 9.60

Rearrange the formula to find M

M = 9.60 / (5/7) / (5/7) = 18.816

<h2>Monthly Allowance = $18.816</h2>

What is the equation of this line?
andrew-mc [135]
One way to write a line is y=mx+b, where b is a number, m is the slope of the line, and y and x are variables that you can plug numbers into. We know that we have two points, (0,5) and (10,0). To find the slope of a line, we can use the equation
\frac{y_{2}-y_{1}}{x_{2}-x_{1}} =  \frac{y_{1}-y_{2}}{x_{1}-x_{2}}
Plugging this in for our points, we get \frac{0-5}{10-0} = -5/10=-1/2 as our slope (we get -1/2 by dividing both -5 and 10 by 5 from the previous fraction), making our equation y=(-1/2)x+b. Plugging a point in to find out what b is, we get 0=(-1/2)10+b=-5+b. Adding 5 to both sides to separate the b, we get 5=b, making our equation y=(-1/2)x+5. To find out what x is for (x,2), since the y value comes second, we can plug in 2 into our equation to get 2=(-1/2)x+5. Since we want to solve for x, we have to separate it. Subtracting 5 from both sides, we get -3=(-1/2)x. Since we can multiply -1/2 by its reciprocal (switching the numerator and denominator) to get 1 (and therefore x on the right sides as 1*x=x), we multiply both sides by -2 to get 6=x, making the point (6,2)
