Answer:

1: Slope intercept form is y=mx+b, where m is slope and b is the y-intercept. We can use this form of a linear equation to draw the graph of that equation on the x-y coordinate plane.

2: We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal. If we subtract the same number from both sides of an equation, both sides will remain equal.

A: For example: If you pay 30 dollars a month for your cell phone and 10 cents per minute of usage the monthly cost of using your cell phone would be a linear equation of a function, C, the monthly cost based on the number of minutes you use monthly.

Answer:

A = 12 ft

Step-by-step explanation:

Perimeter ( of SQUARE) B = 64

then each side = 64/4 = 16

AREA of SQUARE C = 400

side X side = 400

then side = sqrt 400

Now use Pyhtagorean Theorem to find leg of right triangle that is

side A Side B hypotenuse Side C

A^2 + 16^2 = (sqrt 400)^2

A^2 = 400 - 256

A^2 = 144 then A = 12 Ft

Evaluating a piece-wise function. 10 pts

kozerog [31]

1. Since -4 doesn’t equal -2, we will use the first function. All you have to do is plug in -4 to x, and you should get

-3

2. -2=-2, so we will use the second function to get the answer of

3

3. Once again we will be using the first function, so just plug 5 into the answer to get

-7.5

Hope this helped :)

What is the sum? StartFraction 3 Over x squared minus 9 EndFraction StartFraction 5 Over x 3 EndFraction.

V125BC [204]

The sum of the two fractional number, which consist in the variable <em>x</em> is in the polynomial function,

$f(x)=\dfrac{5x-12}{(x+3)(x-3)}$

<h3>What is the sum of fraction number?</h3>

Fraction number is the number which is a part of a whole number. It is written with a numerator and denominator.

Fraction number are written as,

$\dfrac{a}{b}$

Here (a) is the numerator and (b) is the denominator.

To find the sum of two fraction numbers, cross multiply both the numbers or find the least common factor as denominator.

The first fraction number given in the problem is,

$\dfrac{3}{x^2+9}$

The second fraction number given in the problem is,

$\dfrac{5}{x+3}$

Let the sum of these number is f(x). Thus,

$f(x)=\dfrac{3}{x^2-9}+\dfrac{5}{x+3}\\f(x)=\dfrac{3}{(x+3)(x-3)}+\dfrac{5}{x+3}\\$

Solve it further as,

$f(x)=\dfrac{3+5(x-3)}{(x+3)(x-3)}\\f(x)=\dfrac{3+5x-15}{(x+3)(x-3)}\\f(x)=\dfrac{5x-12}{(x+3)(x-3)}$

Thus, the sum of the two fractional number is,

$f(x)=\dfrac{5x-12}{(x+3)(x-3)}$

If the length of two sides of an isosceles triangle are 5 and 12 what is the length of the third side

svetoff [14.1K]

By definition, an isosceles triangle has 2 of the 3 sides with the same length. From this, we already know that the third side must be or 5 or 12.

We also know that, for every triangle, the sum of two sides must be always bigger than the third side, for any combination.

From this second affirmation, we know that the third side can not be 5, because:

$5+5$

From this, we conclude that the third side of an isosceles triangle with sides equal to 5 and 12 is equal to 12.
