Answer:
the answer is X=8
Step-by-step explanation:
2(8)+4=20
Answer:
IQR: 20
Range: 52
Step-by-step explanation:
IQR = 88 - 68 = 20
Range = 100 - 48 = 52

-1 -1 - 1 = -2 3 3 - 2 = 1
-3 -3 - (-1) = -2 4 4 - 3 = 1
So, as you see y in increasing in regular constant intervals, when x also increases in regular constant intervals. => Δy / Δx = constant.
That is the result of a linear function, not an exponential one.
So, the true statement is given by the option <span>(A) No; the domain values are at regular intervals and the range values have a common sum 1. </span>
Answer:
not a solution
Step-by-step explanation:
y = -3/4 x +3
Is (3,2) a solution?
Substitute the point into the equation and see if it is true
2 = -3/4(3) +3
2 = -9/4 +3
2 = -9/4 +16/4
2 = 7/4
False
