Write the equation of the line perpendicular to 2x+3y=9 that passes through (-2,5). Write your answer in slope-intercept form. S
amid [387]

Answer:

y = (3/2)x + 8

Step-by-step explanation:

Hi

First let's find the slope of the given line by converting to slope-intercept form:-

2x + 3y = 9

3y = -2x + 9

y = (-2/3)x + 3

From this we see that the slope is -2/3.

The slope of a line perpendicular to this one will be - 1 /  (-2/3)

= 3/2.    ( because for a line and its perpendicular, the slopes' product = -1).

Using the point-slope form  to find the equation of this line

y - y1 = m(x - x1).  Here m = slope and (x1, y1) is a point on the line.

Plugging in the given values ,  m = 3/2 , x1 = -2 and y1 = 5:-

y - 5 = 3/2 (x - -2)

y - 5 = 3/2x + 3

y = (3/2)x + 8   which is the equation in slope-intercept form.

A horse-drawn carriage tour company has found that the number of people that take their tour depends on the price charged per cu
jonny [76]

Answer:

Option B- The horse-drawn carriage tour company can expect to take in $5760 when the charge per customer is $60.

Step-by-step explanation:

Given :

The function c(x)=50+5x  represents price charged per customer where x is the number of $5 increases they charge over a rate of $50 per person.

The function p(x)=100-2x represents the number of customers expected for the day, where x is the number of $5 increases they charge over a rate of $50 per person.

To find : (p⋅c)(2) mean about the horse-drawn carriage tour company.

Solution :

(p.c) means we multiply the p(x) and c(x)

(p.c)(x)=p(x)\times c(x)

(p.c)(x)=(100-2x)(50+5x)

(p.c)(x)=5000+500x-100x-10x^2

(p.c)(x)=5000+400x-10x^2

Substitute the value of x=2

(p.c)(2)=5000+400(2)-10(2)^2

(p.c)(2)=5000+800-10(4)

(p.c)(2)=5800-40

(p.c)(2)=5760

The horse-drawn carriage tour company can expect to take in $5760.

The function c(x)=50+5x  represents price charged per customer.

For x=2

c(x)=50+5(2)  

c(x)=50+10  

c(x)=60

The charge per customer is $60.

Therefore, Option B is correct.

The horse-drawn carriage tour company can expect to take in $5760 when the charge per customer is $60.
