Cheryl writes 7 fewer posts than Kevin on a social media site.

Answer the questions to write an algebraic expression. Then evaluate the expression for the given value.

1. Choose a variable to represent the number of posts Kevin writes. Explain why you chose this variable. (2 points)

The expression will be P for "of posts Kevin writes." 

2. Which operation (addition, subtraction, multiplication, or division) applies to this situation? Justify your choice. (2 points)

 The operation I will use is subtraction so P-7.

3. Use your variable and the operation you identified to write an expression for the number of posts Cheryl wrote. (3 points)

The expression 16x2 + 4x + 125 represents the height, in feet, of a rock, x seconds after being thrown from a cliff. What does the 125
represent?
O A. the initial height of the rock
O B. the number of seconds it takes the rock to hit the ground
o C. the number of seconds it takes the rock to reach its maximum height
D. the maximum height of the rock

Answers

The motion of the rock thrown from the cliff which goes downwards due to

the gravitational force, is a free fall motion.

125 represents; A. The initial height of the rock.

Reasons:

The given function that represents the height of the of the rock in feet x seconds after being thrown is; f(x) = 16·x² + 4·x + 125

At the initial height before being thrown from the cliff, we have;

The time, x = 0

The initial height is therefore;

The initial height f(0) = 16 × (0)² + 4 × (0) + 125 = 125

125 represents A. The initial height of the rock

Write an equation of a line that is perpendicular to y = 2/3 x + 8 and has a y-intercept of
2.
Answer in slope-intercept form

Answers

Answer:

y = -3/2x + 2

Step-by-step explanation:

Since you know it has a point at (0, 2) - the y intercept, put those values into the equation and solve. To be perpendicular it seems the reciprocal of the slope with the opposite sign, so 2/3 is the original slope, and -3/2 becomes the new slope.

y = 2/3x + 8 becomes

2 = -3/2(0) + b  We substitute in the x and y values, but we have to figure out what the last number will be.

2 = 0 + b

b = 2

So put the whole equation together

y = -3/2x + 2

a farm is sold for $457000, which gives a profit of 19%. Find the profit

Answers

Answer:

The profit is 86830

Step-by-step explanation:

To calculate percentage, just multiply the original number by the percent as a decimal. 457000x0.19=86830

Answer:

Profit: $73000

Step-by-step explanation:

Profit = Selling price (SP) - Cost price (CP)

First you need to find the CP

CP = (SP*100)/(100+Percentage profit)

SP= $457000

Percentage profit = 19%

CP= (457000*100)/(100+19)

CP= 45700000/119

CP= $384,033.6134

Profit = 457000-384,033.6134

Profit = $72966.3866

Profit rounded to the nearest 1,000 or  the Thousands Place = $73,000

Let's simplify the expression,

→ 4 + 5(2x - 3) - 6x

→ 4 + 10x - 15 - 6x

Hence, the answer is 4x - 11.

What is the value of x + y for the system of equations y= 2x - 2 and y= 4x + 6?

Answers

Answer:

x= -1

y= 2

Step-by-step explanation:

Notice that when x = 0 the value of y is 2/1 so this line "cuts" the y axis at y= 2

 y-intercept = 2/1  =  2

When y = 0 the value of x is 1/-1 Our line therefore "cuts" the x axis at x= -1

 x-intercept = 2/-2 = 1/-1  = -1

Colinear means on the same line, and you can tell ABC are all on the line in the middle of the parallelogram. Another way to do this if you don't know what colinear means is to look for the similarities between the points. The only similarity between any of the points is that three are on the same line, meaning they must be colinear and have the right answer.

Step-by-step explanation:

A group of friends wants to go to the amusement park. They have $180.50 to spend on parking and admission. Parking is $19.50, and tickets cost $23 per person, including tax. Write and solve an equation which can be used to determine pp, the number of people who can go to the amusement park.
equation:
answer p:

Answers

a.

The required equation is  23p + 19.50 = 180.50

Let p represent the number of people who can go to the amusement park.

Since the ticket costs $23 per person, the total amount paid for ticket is rate × number of person = $23 × p = 23p.

Since we pay $19.50 for parking, the total amount spent is T = 23p + 19.50

Since the total amount equals $180.50. T = 180.50

So, 23p + 19.50 = 180.50

The required equation is  23p + 19.50 = 180.50

b.

Solving 23p + 19.50 = 180.50, we have

23p = 180.50 - 19.50

23p = 161

p = 161/23

p = 7

So, the number of people who can go to the amusement park is 7.
