Answer:
C
Step-by-step explanation:
6(a+b) + 2z = -8 ; divide by 2
3(a+b) + z = -4
a+b+z = 2; subtract z from both sides
a+b = 2-z; substitute a+b into equation 3(a+b) +z = -4
3(2-z) +z = -4; distribute
6 - 3z+ z= -4 ; subtract 6 on both sides
-3z + z = -4 -6 ; combine like terms
-2z = -10; divide both sides by -2
z= 5
3(a+b) +z = -4; substitute z by 5
3(a+b) +5 = -4; subtract 5 from both sides
3( a+b) = -4 -5; combine like terms
3(a+b) = -9; divide both sides by 3
(a+b) = -3
Answer:
f(x) = .8 (215 - .45 x)
f(x) = .8 (215 - .45 * 75) = .8 ( 215 - 34) = .8 (181) = 145
Answer:
f (0) = 0
Step-by-step explanation:
As <em>Domain = {all whole numbers}
</em>
Range is <em>R = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
</em>
then f (0) = 0 which is its largest place value digit.
Answer:
C: 0.5
Step-by-step explanation:
The probability of any outcome is the long-term relative frequency of that outcome. Probabilities are between zero and one, inclusive (that is, zero and one and all numbers between these values).
