Answer:
-1/8
Step-by-step explanation:
The given expression is y⁻³
We want to find the value of the expression when y = -2
Thus;
At y = -2, we have; -2⁻³
According to law of exponents, x⁻⁴ = 1/x⁴
Thus; -2⁻³ = -1/2³ = -1/8
Answer:
p = 72
q = 18
Step-by-step explanation:
Complementary means they add to 90o
p + q = 90
p = 4*q
Substitute 4q for p
4q + q = 90 Combine
5q = 90 Divide by 5
5q/5 =90/5
q = 18
p = 4q
p = 4*18
p = 72

Answer:
Perimeter of trapezoid = 6x - 1
Step-by-step explanation:
a trapezoid has two bases (x and 2x) and two sides ( x+2 and 2x-3)
To find the perimeter you add all both bases and both sides
Perimeter of trapezoid = x + 2x + (x+2) + (2x-3); add x's
Perimeter of trapezoid = 6x + 2 -3 ; subtract the numbers
Perimeter of trapezoid = 6x - 1
Answer: 8.5, 4, 8, 4, 20.5
Explanation:
Mode : 4
Median : 8
Mean : (8.5 + 4 + 8 + 4 + 20.5)/5 = 45/5 = 9
Range : 20.5 - 8.5 = 12
