Answer:
B
Step-by-step explanation:
(74+72+76+80+73+(AnswerB)75)÷6(total number of quizzes include the one she needed to take)=75(minimum average because she needs to get average of 75)
7^2 + 6^2 = h^2
49 + 36 = h^2
85 = h^2
√85 = h
h = 9.21m

Answer:
(-2, 4)
Step-by-step explanation:
y = -3x - 2
y = -x +2
=> -3x - 2 = -x +2
-3x + x = 2 + 2
-2x = 4
x = -2
-x + 2 = y
2 + 2 = y
4 = y
The Pythagorean Theorum formula is a(squared) + b(squared)= c(squared). If you plug in the numbers, the equation is 39(squared) + 80(squared)= c(squared). That simplifies to 1521+6400=c(squared). Adding results in 7921=c(squared). Finally, when you take the square root of both sides, you are left with 89=c (aka the hypotenuse)
