What is the slope of a line that is perpendicular to the line<br> v= -1/3x - 6
Amiraneli [1.4K]

Answer:

3

Step-by-step explanation:

the slope of a perpendicular line is the negative reciprocal of the original slope

a reciprocal is the inverse of a number, to find the reciprocal, just flip the numerator and denominator

in this cause, the slope is -1/3

the negative of it is 1/3 and the reciprocal is 3

A washer and a dryer cost $770 combined. The washer costs $70 more than the dryer. What is the cost of the dryer?
vazorg [7]
Let w = washer and d = dryer:

w + d = $770,
but w = d + 70, replace w with d+70
(d+70) + d = 770
2d + 70 =770
2d = 770 -70 = 700
and d=$350, then w=350+70 = 420

Prove that: 5^31–5^29 is divisible by 100.
ANEK [815]

Answer:

See explanation

Step-by-step explanation:

Consider the expression

5^{31}-5^{29}

First, factor it:

5^{31}-5^{29}=5^{29}\cdot(5^2-1)=5^{29}\cdot (25-1)=24\cdot 5^{29}

Note that

100=25\cdot 4

Then

5^{31}-5^{29}=24\cdot 5^{29}=6\cdot 4\cdot 25\cdot 5^{27}=6\cdot 100\cdot 5^{27}

This shows that number 100 is a factor of the expression 5^{31}-5^{29} and, therefore, this expression is divisible by 100.
