Answer:
m = 
Step-by-step explanation:
Given
+
= 
Multiply through by 15 to clear the fractions
15 is the lowest common multiple of 3, 5 and 15
10 + 9m = 31 ( subtract 10 from both sides )
9m = 21 ( divide both sides by 9 )
m =
= 
Answer:
f(4) = 9
Step-by-step explanation:
You just need to substitute 4 in for x.
f(4) = 5(4) - 11
f(4) = 20 - 11
f(4) = 9
Answer:
The measure of ∠D = (Q) = 28.81
Step-by-step explanation:
Tan(Q) = perpendicular/ base
In this case perpendicular is BC and base is DC
BC =25 DC = 45
Tan(Q) = BC/DC
Tan(Q) = 25/ 45
Tan(Q) = 5/ 9
(Q) = tan^ -1 (0.55)
(Q) = 28.81
