(35/47)^0 worth 10 points

Explanation:

The rule is

x^0 = 1

where x is nonzero (ie, not equal to zero). So whatever number you raise to the zeroth power, the answer is always 1.

Let's see why this rule works

x^1 = x   ... raising something to the first power is itself

(x^1)/x = x/x ... divide both sides by x

(x^1)/x = 1 turn the 'x/x' into 1

(x^1)/(x^1) = 1 rewrite the second 'x' as 'x^1'

x^(1-1) = 1 ... subtract exponents

x^0 = 1

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
