Answer:
x = 5
Step-by-step explanation:
y = -4x + 5 4x + y = 10
substitute the y in the second equation with
(-4x +5).
4x + (-4x + 5) = 10 then add like terms.
x + 5 = 10 solve for x.
10 - 5 = 5 make sure to check your answer.
5 + 5 = 10
Based on the given information, let x represent the grade for the fifth quiz.
(79+88+95+71+x)/5=85
(333+x)/5=85
333+x=425
x=92
Jackson would have to earn a 92 on his fifth quiz to earn an average of 85.
9x^4 -225y^8
= 9(x^4 - 25y^8)
= 9(x^2 + 5y^4)(x^2 - 5y^4)
