Answer:
y=5
x=7
Step-by-step explanation:
When given an expression in the form a⁻ᵇ the expression is the same as 1/aᵇ where a and b are integers.
Solving the question by giving the equivalents of the expression:
Therefore (-j)⁻⁷ is the same as 1/j⁷
The value of x=7
k⁻⁵+m⁻¹⁰=1/k⁵+1/m¹⁰
Therefore the value of y is 5.
Answer:
radius is 7.5cm and the diameter is 15cm
Step-by-step explanation:
Radius = 7.5cm.
The diameter of a circle is twice the length of the radius.
Therefore the radius is 7.5cm and the diameter is 15cm!
Hope this answer helps you :)
Have a great day

31.5 x 1.8 = 56.7, and 56.7 / 1.8 = 31.5
Answer:
x = 3 or x = 2 or x = -1 or x = -5
Step-by-step explanation:
Solve for x:
((x - 3) (x - 2) (x + 1) (x + 5))/x = 0
Multiply both sides by x:
(x - 3) (x - 2) (x + 1) (x + 5) = 0
Split into four equations:
x - 3 = 0 or x - 2 = 0 or x + 1 = 0 or x + 5 = 0
Add 3 to both sides:
x = 3 or x - 2 = 0 or x + 1 = 0 or x + 5 = 0
Add 2 to both sides:
x = 3 or x = 2 or x + 1 = 0 or x + 5 = 0
Subtract 1 from both sides:
x = 3 or x = 2 or x = -1 or x + 5 = 0
Subtract 5 from both sides:
Answer: x = 3 or x = 2 or x = -1 or x = -5
