The pythagorean theorem says that a² + b² = c²

You're given the b and the c so substitute the values in: a² + 12² = 15²

a² + 144 = 225; subtract 144 from both sides

a² = 81; square root each side

a = 9, or choice C

-9=-3(x+2)<br>solve for x <br>show steps
lianna [129]

SimplifyOkie dokie so first things first, you have to get rid of those parentheses! To do this you use the distributive property. -3(x+2) is the same thing as -3(x)+-3(2). that and you get -9=-3x-6. So you want to get x by itself to be able to find what x is, so you add 6 to both sides of the equation to get rid of the -6. So then you get -3=-3x. Then you must divide both sides by the coefficient of x, which would be -3. When you divide both sides by -3 you get -3/-3=x, which is the same thing as 1=x. Hope this helped!

What is the rate of change for the function f(x)=2x-3
Stolb23 [73]

Answer:

2

Step-by-step explanation:

f(x) = 2x - 3 is a linear function

The rate of change of a linear function is the measure of the slope.

The equation is in slope- intercept form, that is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x - 3 has slope m = 2

Thus rate of change = 2
