A^2+b^2=c^2
20^2+b^2=29^2
400+b^2=841
-400. -400
b^2=√441
b=21
Answer:
[1, 2.5]
Step-by-step explanation:
A rate of change on x- axis is defined as positive if the function increases as x does, and defined negative if y decreases as x increases.
Thus, we only need to see in which of those intervals [–2, –1] , [–1.5, 0], [0, 1]. [1, 2.5] the graph of the function goes only down if we look it from left to right.
The only one interval satisfying this condition is [1, 2.5].
Answer:
Step-by-step explanation:
x = the mom...y = joe
x = 3y - 2
x = 31
31 = 3y - 2
31 + 2 = 3y
33 = 3y
33/3 = y
11 = y <=== joe is 11
