Line c passes through points (1, 14) and (7, 7). Line d is perpendicular to c. What is the slope of line d?
anyanavicka [17]

Answer:

6/7

Step-by-step explanation:

Your first step will be to find the slope of Line C. Using the slope formula of \frac{y_{2}-y_1 }{x_2-x_1}, the slope of Line C is \frac{7-14}{7-1} = \frac{-7}{6}.

If Line D is perpendicular to C, that means the slope is the negative reciprocal of Line C. So, that means the slope is 6/7.

The ordered pair (a,b) satisfies the inequality y>x+10. Which statement is true?
Morgarella [4.7K]

Answer:

b-a>10\\\\Difference\ of\ b\ and\ a\ is\ greater\ than\ 10.

Step-by-step explanation:

Ordered Pair: In an ordered pair (p,q) first value that is p represents x-value and second value(q) represents y-value.

Given\ inequality\ y>x+10\\\\Ordered\ pair (a,b)\ satisfies\ the\ inequality\\\\Hence\ x=a,\ y=b\\\\Substitute\ these\ values\ in\ the\ inequality.\\\\b>a+10\\\\\Rightarrow b-a>10\\\\That\ means\ difference\ of\ b\ and\ a\ is\ greater\ than\ 10.

By what percent will the fraction increase if its numerator is increased by 60% and denominator is decreased by 20% ?
seropon [69]

Answer:

100%

Step-by-step explanation:

Start with x.

x = x/1

Increase the numerator by 60% to 1.6x.

Decrease the numerator by 20% to 0.8.

The new fraction is

1.6x/0.8

Do the division.

1.6x/0.8 = 2x

The fraction increased from x to 2x. It became double of what it was. From x to 2x, the increase is x. Since x was the original number x is 100%.

The increase is 100%.
