Answer: Choice D

(a-e)/f

=======================================

Explanation:

Points D and B are at locations (e,f) and (a,0) respectively.

Find the slope of line DB to get

m = (y2-y1)/(x2-x1)

m = (0-f)/(a-e)

m = -f/(a-e)

This is the slope of line DB. We want the perpendicular slope to this line. So we'll flip the fraction to get -(a-e)/f and then flip the sign from negative to positive. That leads to the final answer (a-e)/f.

Another example would be an original slope of -2/5 has a perpendicular slope of 5/2. Notice how the two slopes -2/5 and 5/2 multiply to -1. This is true of any pair of perpendicular lines where neither line is vertical.

This baseball season, Barry gets two hits for every 16 at bats. This statement represents his batting average.
Katen [24]

Answer:

A. 1/8 or 0.125

B. No

Step-by-step explanation:

A. The batting average formula is: (# of hits) ÷ (# of at-bats).

Here, we see that Barry has 2 hits and 16 at-bats, so plug these numbers into the formula:

(# of hits) ÷ (# of at-bats)

2 ÷ 16 = 1/8 = 0.125

B. Batting average is always rounded to the thousandths place; in other words, we only calculate the number up to the third decimal place.

Looking at our batting average calculated in part A, it's 0.125, which is already at the third decimal place, and we can see that there is clearly no 0 at the end. So, the answer is no.

Twice the difference of a number and 8 is equal to three times the sum of the number 2
exis [7]

Answer:

-22

Step-by-step explanation:

Let the unknown be x,

Step 1: You first write the question in equation form,

2(x-8)=3(x+2)

Step 2: You clear the brackets by multiplying the number outside with the numbers inside the bracket,

2x-16=3x+6

Step 3: Collect like terms,

2x-3x=6+16

Step 4;Solve

2x-3x=6+16

-x=22

<em>Therefore </em><em>x=</em><em>-</em><em>2</em><em>2</em>
