Hoochie [10]3 years ago

Answer:

(x - 5) and (x + 4)

Step-by-step explanation:

Since -20 = (-4)(5) or (4)(-5), and since -5x + 4x becomes -1x, we know right away that the factors are (x - 5) and (x + 4).

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.

ASHA 777 [7]

1. 5/8 + 1/8 = 6/8 --> 3/4

3. - 1/4+ 3/4:

  -0.25+0.75= 0.5 OR 1/2

5. 5/9 + 5/9 = 10/9 --> 1 whole 1/9

7. 3/10 + 1/10 = 4/10 --> 2/5

9. 7/15 + 4/15 = 11/15

And I simplified them too :P

Also this is ez, to me :PP

3+5+3=11 marbles

15-11= 4 that means the rest of them are red.
