Answer:

I assume you want the equation for the line in y=mx+b form, if not, you can just transfer this form to standard or intercept. y=(-3/4)x+2.5

Step-by-step explanation:

Since you have the slope and a point, plug in the points to the equation y=9-3/4)x+b to get 4=(-3/4)(-2)+b and solve.

James sold 450 tickets for the community play. Tickets for children cost $2, and tickets for adults cost $5. James sold $1,800 w

nlexa [21]

Answer:

James sold 300 tickets for adults

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of tickets sold by James = 450

Cost of a child ticket = $ 2

Cost of an adult ticket =$ 5

Amount of money collected by James after selling the 450 tickets for the community play = $ 1,800

2. How many tickets for adults did James sell?

x = Number of adult tickets James sold

450 - x = Number of children tickets James sold

For solving for x, we write this equation:

5x + 2 * (450 - x) = 1,800

5x + 900 - 2x = 1,800

3x = 1,800 - 900

3x = 900

x = 900/3 = 300

450 - x = 450 - 300 = 150

James sold 300 tickets for adults and 150 for children

If a < 0 and c > b, circle the expression that is greater:

matrenka [14]

Answer:

The expression that is greater is a (b - c)

Step-by-step explanation:

a < 0 and c > b, this means (by the addition property) that c - c > b - c⇒0 > b - c

so for the product a(b - c) we would have a multiplication of a negative number a and another negative number (b - c). We know that the result of the multiplication of two negative numbers is a positive number.

Therefore, a (b - c) > 0

a < 0 and c > b, this means by the addition property that c - b > b - b⇒ c - b > 0

so for a(c - b), we have the negative number a multiplied by the positive number (c - b). We know that the result of the multiplication of a negative number by a positive number is negative.

Therefore a (c - b) < 0

Thus, the expression that is greater is the positive one which is a (b - c)

What were some of the challenges pilgrims faced on their journey

EleoNora [17]

On the ocean Pilgrims encounter fierce storms, disease, and their ship falls into disrepair. During the first winter they lack shelter, warmth, and food.

The Pilgrims struggled to build homes, and many families crowded into the few homes that were built. Food was scarce, and many Pilgrims starved to death that first winter.

Hope this helped

What is the best way to classify each equation? 22-3x+7x=4(x+5) ,6(2x-3=3(3-5), 6x-14=2(3x-7), 6x+3(x-4)=8(x-3)

Romashka-Z-Leto [24]

1. 22 - 3x + 7x = 4(x + 5)
 22 - 3x + 7x = 4x + 20
 +3x +3x +3x 
 22 + 10x = 7x + 20
 -7x -7x 
 22 + 3x = 20
 -22 -22
 3x = -2
 3 3
 x = -2/3

2. 6(2x - 3) = 3(3 - 5)
 12x - 18 = 3(-2)
 12x - 18 = -6
 +18 +18
 12x = 12
 12 12
 x = 1

3. 6x - 14 = 2(3x - 7)
 6x - 14 = -3x
 6x - 14 = 2(-7)
 6x - 14 = -14
 +14 +14
 6x = 0
 6 6
 x = 0

4. 6x + 3(x - 4) = 8(x - 3)
 6x + 3x - 12 = 8x - 24
 9x - 12 = 8x - 24
 -8x -8x 
 x - 12 = -24
 +12 +12
 x = -12
