Answer:
84
Step-by-step explanation:
45 + 39 = 84
Hello,
Yes,
imagine 2 rights triangles having the hypotenus in commun.
Multiply 8/3 by 3/5 and get 8/5
(79 + 93 + 91 + 68 + x) / 5 = 80
(331 + x) / 5 = 80.....multiply both sides by 5
331 + x = 80 * 5
331 + x = 400
x = 400 - 331
x = 69 <=== he would have to make at least a 69
The answer is B.
Slope-intercept line is written as:
y=mx+b
m=slope
b=y-intercept
4 is the y-intercept because the line crosses the y-axis at 4.
The slope is -2 over 5, because slope is written as y over x.
So, if you start at the point at the 4, count 2 spaces down and 5 spaces right. The line crosses the point exactly, which is how you know the slope is accurate.
