Answer:
88
Step-by-step explanation:
this question is a question that involves the use of the statistical principles of finding average
let the summation of the six scores of the biology test be represented as ∑x
∴ ∑x÷ 6=74
∑x=74 × 6
=444
444 is the summation of all the scores of all the six biology scores reuben had
the next test would be his 7th
let y represent the score for the 7th test
therefore, 
= 76
444 + y = (76 × 7)
444 + y = 532
y=88
Reuben needs to score 88 to raise his average to 76
"Line L has an undefined slope" so line L is any vertical line.
Anything perpendicular to this vertical line will be horizontal. So line M is horizontal.
Horizontal lines are of the form y = k for some fixed number k. The only thing that fits is choice B) y = 7 where k = 7 in this case.
Choice A graphs out a diagonal line, choice C graphs a vertical line, while choice D graphs out a hyperbola. These facts are why we can eliminate these non-answers.
Answer: Choice B) y = 7
Answer:
Step-by-step explanation:
Important: Please use " ^ " to indicate exponentiation: 5(3x - 4)^2 is correct.
This is "five times the square of the difference between 3x and 4."
5.
the diagonal squared = base squared + altitude squared.
