8=108 degrees because 180-92=108
Answer:
Step-by-step explanation:
y=9x-1
8x-4y=92
substitute y=9x-1
8x-4(9x-1)=92
8x-36x+4=92
-28x+4=92
-28x=92-4=88
x=88/-28=22/-7 = -3.14
y = 9(-3.14) -1 = -28.26-1 = -29.26
Answer:
4x² - 20x + 16
Step-by-step explanation:
Given
(4x - 4)(x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
4x(x - 4) - 4(x - 4) ← distribute both parenthesis
= 4x² - 16x - 4x + 16 ← collect like terms
= 4x² - 20x + 16
V=πr^2h
h=4.5
r=6
v=22\7 x 6 x 6 x 4.5
v=509.142857
v=509cubic unit
Step-by-step explanation:
a. the domain ={-3, 0, 1, 2}
the range = {6, 2, 0, -3}
the relation is a function
b. the domain = {-1, 2, 1}
the range = { -4, 8, 4}
the relation is not a function
