6x — 5y = 15
x = y + 3
х =
y =

Answers

Answer 1

Replace all occurrences of x with y + 3 in each equation.

Replace all occurences of x in 6x - 5y = 15 with y + 3.

6 (y+3) -5y = 15

x = y + 3

Simplify 6 (y + 3) - 5y.

Simplify each term.

Apply the distributive property.

6y + 6 · 3 - 5y = 15

x = y + 3

Multiply 6 by 3.

6y + 18 - 5y = 15

x = y + 3

Subtract 5y from 6y.

y + 18 = 15

x = y + 3

Move all terms not containing y to the right side of the equation.

Subtract 18 from both sides of the equation.

y = 15 - 18

x = y + 3

Subtract 18 from 15.

y = -3

x = y + 3

Replace all occurences with y with -3 in each equation.

Replace all occurences of y in x = y + 3 with -3.

x = (-3) + 3

y = -3

Add -3 and 3.

x = 0

y = -3

The solution to the system is the complete set of ordered pairs that are valid solutions.

Are the graphs of the equations parallel, perpendicular, or neither? y = 4x + 1 and y = -4x -

Answers

Answer:

I am not sure if you fully typed the second equation, but both of these that are written down intersect, there for are perpendicular.

If the second equation is incorrect, let me know and I'll be happy to help you :)

Neither.

Parallel lines have the same slope, while perpendicular lines have negative reciprocal slopes (multiplying their slopes result in a product of - 1). The negative reciprocal of 4 is -1/4, and the negative reciprocal of -4 is 1/4.

Since the slopes of both lines are not the same, and that they are not negative reciprocals, then the correct answer is neither.

find the mean of
35,26,31,16,21,23,27,30,26,17,19,27​

Answers

Hello!

To find the mean, we must add all the terms in the dataset and divide by how many there are.

35+26+31+16+21+23+27+30+26+17+19+27=450

There are 12 terms in the dataset, so we divide by 12:

37.5

So the mean of this set is 37.5.

slope = [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (7, 5) and (x₂, y₂ ) = (3, 2) ← points on graph

m = [tex]\frac{2-5}{3-7}[/tex] = [tex]\frac{-3}{-4}[/tex] = [tex]\frac{3}{4}[/tex]

Determine whether the function shown in the graph is even or odd.

The graph starts at the bottom left, continues up through the x-axis near negative one point seven five to a maximum around y equals two, goes back down through the x-axis at the origin to a minimum around y equals negative two, and goes back up through the x-axis near one point seven five.

A) The function is even because it is symmetric with respect to the y-axis
B) The function is odd because it is symmetric with respect to the y-axis.
C) The function is even because it is symmetric with respect to the origin.
D) The function is odd because it is symmetric with respect to the origin.

17. A salesperson earns a base monthly salary of $2000 plus a 10% commission on sales. The salesperson's
monthly income I (in dollars) is given by the function I(s) = 0.1s + 2000, where s is the sales (in
dollars) that the salesperson makes. Sketch a graph to illustrate each situation using the graph of
I(s) = 0.1s + 2000 as a reference.

A. The salesperson's base salary is increased.

B. The salesperson's commission rate is decreased.

Answers

The earning of the salesperson is an illustration of a linear function.

The possible functions in the two scenarios are: [tex]\mathbf{I(s) = 0.1s + 2500}[/tex] and [tex]\mathbf{I(s) = 0.05s + 2000}\\[/tex]

The function is given as:

[tex]\mathbf{I(s) = 0.1s + 2000}[/tex]

When the base salary is increased, a possible function is:

[tex]\mathbf{I(s) = 0.1s + 2500}[/tex]

This is so, because 2500 is greater than 2000

When the commission rate is decreased, a possible function is:

[tex]\mathbf{I(s) = 0.05s + 2000}\\[/tex]

This is so, because 0.05 is less than 0.1

So, the possible functions in the two scenarios are:

[tex]\mathbf{I(s) = 0.1s + 2500}[/tex] and [tex]\mathbf{I(s) = 0.05s + 2000}\\[/tex]

A 2 feet- wide walkway surrounds a rectangular swimming pool. The swimming pool is 12 feet wide and 16 feet long. What is the area of the walkway

Answers

Answer:

128 sq. ft.

Step-by-step explanation:

The outer sides of the walkway will have a length of 20 feet and the breadth will be 16 feet

The area of the pool along with the walkway will be 20 × 16 = 320 square feet.

Area of the pool without the walkway will be 16 × 12 = 192 square feet.

Therefore area of the walkway will be

352 - 216 = 128 square feet.

Answers

Answer:

x = 2

Step-by-step explanation:

5(x-4) =-10

Distribute 5 by multiplying x and -4 by 5

5x - 20 = -10

Add 20 to both sides

5x - 20 + 20 = -10 + 20

5x = 10

Divide both sides by 5

5x ÷ 5 = 10 ÷ 5

x = 2

-Chetan K

5(x-4)=-10 (multiply 5 to x and -4)
5x-20= -10 (add 20 to -10)
5x=10 (divide both sides by 5)

Bill and Ben each have three cards, numbered 1, 2 and 3. They each take one of their own cards. Then they multiply together the two numbers on the cards. a) What is the probability that their answer is an even number? b) What is the probability that their answer is a number greater than 5?​

Answers

The probabilities are given as follows:

a) Even number: 5/9.

b) Number greater than five: 1/3.

What are probabilities?

A probability is the division of the number of desired outcomes by the number of total outcomes.

Given that each person draws one card from a set of three, hence the total number of outcomes is given as follows:

3² = 9.

Using the Fundamental Counting Principle,

The nine outcomes are given as follows:

1 x 1 = 1.

1 x 2 = 2.

1 x 3 = 3.

2 x 1 = 2.

2 x 2 = 4.

2 x 3 = 6.

3 x 1 = 3.

3 x 2 = 6.

3 x 3 = 9.

There are five outcomes that end with an even number, hence the probability is of:

p = 5/9.

There are three outcomes ending with a number greater than five, hence the probability is of:

p = 3/9 = 1/3.
