Answer:
A
Step-by-step explanation:
substitute the values from the replacement set into the right side of the equation to find which values of x make the equation true.
x = - 32
+ 5 = - 8 + 5 = - 3 ← True
x = 8
+ 5 = 1 + 5 = 6 ≠ - 3 ← False
x = 32
+ 5 = 8 + 5 = 13 ≠ - 3 ← False
the solution is therefore x = - 32
Answer:
m = 10 , n = 5
Step-by-step explanation:
using the cosine and tangent ratio in the right triangle and the exact values
cos45° = and tan45° = 1 , then
cos45° = =
=
( cross- multiply )
m = 5 ×
= 5 × 2 = 10
-----------------------------------------
tan45° = =
= 1 , then
n = 5
Answer:
9 students on the committee are males
