85%=85/100=0.85
'of' means multiply

85% of x equals 17 means
0.85 times x=17
divide both sides by 0.85
x=20

the number is 20

I’m still trying to do my work and trying to figure out this

swat32

The slope of a vertical line is undefined, D.

If you were to try to solve use something like the rise over run method, you would end up with a 0 in the denominator. Since dividing by 0 gives you an undefined result, the slope would be undefined.

What is the length of leg y of the right triangle?

xz_007 [3.2K]

Answer:

Step-by-step explanation:

We need to use the Pythagorean Theorem to solve this problem:

$a^{2} +b^{2} = c^{2}$ , where a and b are the legs of the right triangle and c is the hypotenuse

In this case, we already know b (b = 84) and c (c = 85), so we need to solve for a:

$a^{2} = c^{2} - b^{2} = 85^{2} - 84^{2} = 169 = 13^{2}$

Thus, a = y = 13.

Determine the range of the function? Y=2x(squared) +3

coldgirl [10]

The range of y = x^2 is the set of nonnegative numbers. The same applies to y = 2x^2 as well. Shift everything up three units to get y = 2x^2+3

So the range is the set of numbers y such that $y \ge 3$

The final answer is choice C.
