Answer:
y = 2x – 13
Step-by-step explanation:
Use Slope formula to get the slope
(y2-y1) / (x2-x1)
(-7--1) / (3-6)
(-6)/(-3)
2
Then plug-in the value of slope and any one coordinate in Point-Slope formula:
y- y1= m(x-x1)
y - -1 = 2( x - 6)
y + 1 = 2x - 12
y = 2x - 13
You have to solve the exponent in the parentheses first:
(2^4)^2
(16)^2
=256
Writing and solving an equation of ratios is the way to go here. See if you can figure out why the following is correct:
x+3 x
----- = -------
12 x+3
Then (x+3)^2 = 12x, and x^2 + 6x + 9 = 12x, so that x^2 - 6x + 9 = 0
This is the square of (x - 3). Thus, x-3 = 0, and x = 3.
The value of x is 3.
Answer:
6 miles
Step-by-step explanation:
Divide to find unit rate 30 ÷ 4
Multiply answer: answer × 45
= 6 miles
whole equation should look like this: 30 ÷ 4 × 45 = 6
