X^{2m+n} * x^{n-m} / x^{m+2n}

Step-by-step explanation:

When bases are same for exponents in division, subtract exponents.

When bases are same for exponents in multiplication, add exponents.

Any base with power or exponent of 0 is 1.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

correct answer is b. 27/8
