What are the coordinates of the point (10,-4) if it is reflected across the y-axis

the answer would be -10,4 because when something is reflected over the y axis the x-value becomes the opposite sign. when something is reflected over the x-axis then the y-value becomes the opposite

Answer:

(10, 4)

Step-by-step explanation:

The easiest way to understand it is to draw it. Please notice that the distance from Y axis is still 4, the point is just at the other side of the axis.

Answer:

$\frac{(x+5)(x+2)}{x(x-3)(x+3)}$

Step-by-step explanation:

The given expression is

$\frac{2x+5}{x^{2} -3x} -\frac{3x+5}{x^{3} -9x} -\frac{x+1}{x^{2}-9}$

First, we need to factor each denominator

$\frac{2x+5}{x(x-3)} -\frac{3x+5}{x(x+3)(x-3)} -\frac{x+1}{(x-3)(x+3)}$

So, the least common factor (LCF) is $x(x-3)(x+3)$ , because they are the factors that repeats.

Now, we diviide the LCF by each denominator, to then multiply it by each numerator.

$\frac{(x+3)(2x+5)-3x-5-x(x+1)}{x(x-3)(x+3)} =\frac{2x^{2}+5x+6x+15-3x-5-x^{2}-x }{x(x-3)(x+3)}\\\frac{x^{2}+7x+10}{x(x-3)(x+3)}$

Then, we factor the numerator, to do so, we need to find two numbers which product is 10 and which sum is 7.

$\frac{(x+5)(x+2)}{x(x-3)(x+3)}$

Therefore, the expression is equivalent to

$\frac{(x+5)(x+2)}{x(x-3)(x+3)}$

The area of a rectangular gymnasium is (5x+5x) square feet. If it is 5x feet wide, what is the length, in feet?

Amiraneli [1.4K]

Answer:

Step-by-step explanation:

Area = L x W gym area is (5x + 5x) ft² if W = 5x Find the L

Area = L x W divide both sides by W

Area/W = (L x W) / W

Area/W = L = Area/W

L = Area/W

= (5x + 5x) / (5x)

= 5x( 1 + 1) / 5x

= 5x(2) / 5x the 5x's cancel each other 5x/5x = 1

= 2 ft I got 2. I suspect the 12 was a typo and should have been 2
