Answer:
x=19, y=-5
Step-by-step explanation:
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
Point Form:
(19, -5)
Equation Form:
x=19, y=-5
Hope this helps.
Answer:
-10
Step-by-step explanation:
9^-8 x 9^-2 = a^b
We know that x^y * x^z = x^(y+z)
9^-8 x 9^-2 = 9^(-8+-2) = 9^(-10)
a= 9
b = -10
Answer: y=(3)/(2)x+5
Step-by-step explanation:
Answer:
C. 10cm
Step-by-step explanation:
First we can rearrange the equation to solve for length (l):
V = lwh
Divide both sides by wh:
l = V/(wh)
Substitute in known values:
l = 1200/(15x8)
l = 1200/120
l = 10cm

Answer and Step-by-step explanation:
When multiplying two numbers (or variables) of the same exponent, the solution would have the exponents adding each other:
When dividing two numbers (or variables) of the same exponent, the solution would have the exponents subtracting each other:
When a number with an exponent is being raised to an exponent, the solution would have the exponents multiplying each other:
When there are two variables in parentheses and an exponent on the outside, the exponent will power both variables:
