Here x1 = -5 , y1 = 0 , x2 = 4 and y2 = 3

equation of straight line

y - y1 = y2 - y1 / x2 - x1 (x - x1)

y - 0 = 3 - 0 / 4 + 5 (x + 5)

y = 3/9 ( x + 5)

9y = 3x + 15

3x + 15 - 9y = 0

Therefore 3x + 15 - 9y = 0 is requried answer.

At Brighton Middle School, Mr. Yule asked 50 randomly selected students from each grade level about their favorite subject, and

Ugo [173]

Answer:

Yes, he made a reasonable inference by saying about 25 percent of students choose the science.

Step-by-step explanation:

Given that

Number of students for survey = 50

Number of students who choose science = 12

Now

Percentage of student who choose science = $\frac{12}{50} x 100$

Percentage of student who choose science = $\frac{12*100}{50}$

Percentage of student who choose science = 24 %

Now as Mr. Yule said "about 25" percent of students choose the science it can be treated as reasonable approximation.

Now if the number of students in survey become 200, then we can expect 12 out of every 50 students would choose the science. So, in total 48 students would choose the science.

Now lets calculate the percentage of students who choose science.

Percentage of student who choose science = $\frac{48}{200} x 100$

Percentage of student who choose science = $\frac{48*100}{200}$

Percentage of student who choose science = 24 %

If (-2,11)and(9,22) are two anchor points on the trend line, then find the equation of the line

Elza [17]

Answer:

The equation of the line is $y=x+13$

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

(-2,11) and (9,22)

substitute

$m=\frac{22-11}{9+2}$

$m=\frac{11}{11}$

$m=1$

step 2

Find the equation in slope intercept form

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=1$

$point\ (-2,11)$

substitute in the equation and solve for b

$11=(1)(-2)+b$

$11=-2+b$

Adds 2 both sides

$b=11+2\\b=13$

The equation of the line is

$y=x+13$

Dr.Bolton was born in an interesting year. The tens digits was twice the thousands digits, the ones Digits was three times the t

kap26 [50]

Answer: Dr. Bolton was born in 1926.

Work:

Let x be the thousands digit. So, you will have the tens digit be 2x, the ones digit be 6x, and the hundreds digit be 9x. Now, let's try x as 1. Then, you will have the thousands digit be 1, the tens digit be 2, the ones digit be 6, and the hundreds digit be 9. Hope it helps!

Which function is the inverse of y=2x+5/2

Svetllana [295]

First you have to change y to x

X= 2y+5/2

Then find y

(X-5/2)/2=y

So (X-5/2)/2 is the. Inverse function
