Asurvey asked 816 college freshmen whether they had been to a movie or eaten in a restaurant during the past week. the following information was obtained: 385 freshmen had been to neither a movie nor a restaurant, and 268 had been to a movie. if 96 of those who had been to a movie had not been to a restaurant, how many of the surveyed freshmen had been to the following?

the answer is 90

Step-by-step explanation:

296-96=90

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
