3/99 = 1/33
So 3 ÷ 99 = 1/33 = 0.030303030303, or 33%
Answer:
slope = 1.4
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = 5, 7) and (x₂, y₂ ) = (10, 14)
m =
=
= 1.4
The answer is C and D
First we must make one side of the equation zero, so we subtract 7 on both sides of the equation, making the equation 9x^2 - 6x - 6 = 0
Then we will use the quadratic formula to find the answers.
using the Quadratic Formula where:
a = 9, b = -6, and c = -6
and the formula is 6 +- ![\sqrt{6^{2} } -4 (9)(6) /2 (9)](https://tex.z-dn.net/?f=%5Csqrt%7B6%5E%7B2%7D%20%7D%20-4%20%289%29%286%29%20%2F2%20%289%29)
21. 6 miles
because
2.4/10 = x/90
The answer to (8+2-4) and (3-5) is 4
