Step-by-step explanation:

To find the slope you use the slope formula which is y2-y2/x2-x1

And to find the y intercept you use y=mx +b. Yous substitute the slope as m and you substitute a point from the line to find b. Which is the y intercept

Answer:

The number of students whom should be admitted is 377.

Step-by-step explanation:

Given:

College has space for 580 students.

The college estimates that 65% of the students who are admitted will attend the college.

Now, to find the number of students whom should be admitted.

Space for total number of students = 580.

Percentage of the students who are admitted = 65%.

Total number of students whom should be admitted = 65% of 580.

$=\frac{65}{100}\times 580$

$=\frac{37700}{100}$

$=377.$

Therefore, the number of students whom should be admitted is 377.

This is the question:

MrRissso [65]

Answer:

$y = \frac{10}{3}x$

B) 240 pages

Step-by-step explanation:

From the table, he can read 20 pages in 6 minutes and 15 paged in 50 minutes.

The unit rate can be found using

$m = \frac{change \: in \: y}{change \: in \: x}$

$m = \frac{50 - 20}{15 - 6}$

$m = \frac{30}{9} = \frac{10}{3}$

Using the point (6,20) and the unit rate we can find the equation using

$y-y_1=m(x-x_1)$

$y - 20 = \frac{10}{3}(x - 6)$

$y=\frac{10}{3}x - 20 + 20$

$y = \frac{10}{3}x$

B) When x=72 minutes we substitute

$y = \frac{10}{3} \times 72$

$y = 10 \times 24 = 240$
