Find the slope using the slope formula and then find the equation of the line using any method

Answers

Answer:

y = 13/7x - 13

Step-by-step explanation:

We are given the x-intercept of (7, 0) and the y-intercept of (0, -13). We can solve for the slope using the formula [ y2-y1/x2-x1 ] and the points given.

-13-0/0-7

-13/-7

13/7

We can write the equation in slope-intercept form which is [ y = mx + b ] where m = slope and b = y-intercept. We are already solved for the slope and was given the y-intercept so we can fill it into the formula.

y = 13/7x - 13

the answer is (4) 0.6x+0.6

Answer:

Answer 4

Step-by-step explanation:

The slope is 7.8-4.8/12-7 = 3/5 = 0.6

So choose between 3 & 4

Plug in one of the points in 3:

7.8=0.6*12+1.8

7.8=7.2+1.8

7.8=9 wrong

Plug in 4:

7.8=0.6*12+0.6

Gavin is moving into a new ampartment that has a kitchen with an area of 50 square feet. If the area of the kitchen is 10 square feet more than 1 _ 3 the area of the bedroom, what is the area of gavin's bedroom?

Answers

Answer:

[tex]B =120[/tex]

Step-by-step explanation:

Given

Represent Kitchen with K and Bedroom with B.

So:

[tex]K = 50ft^2[/tex]

[tex]K = 10 + \frac{1}{3}B[/tex] --- 10 more than 1/3 of Bedroom area

Required

Determine the bedroom area

The expression of K and B has been determined above.

The next step is to substitute 50 for K in the second equaion

[tex]K = 10 + \frac{1}{3}B[/tex]

[tex]50 = 10 + \frac{1}{3}B[/tex]

Multiply through buy 3

[tex]3 * 50 = 3 * 10 +\frac{1}{3}B * 3[/tex]

[tex]150 = 30 +B[/tex]

Make B the subject

[tex]B =150 - 30[/tex]

[tex]B =120[/tex]

Hence, the area of the bedroom is 120ft^2

Find a value of x that is a solution to 5(x – 3) = x + 13. Describe how you found the solution.

Write your answer in the space below.

Answers

Answer:

x=7

because distributive property and addition and subtraction

Answer:

x = 7

Explanation:

5(x – 3) = x + 13

Expand 5(x - 3): 5x - 15

5x - 15 = x + 13

Add 15 To Both Sides

5x - 15 + 15 = x + 13 + 15

Simplify

5x = x + 28

Subtract x From Both Sides

5x - x = x + 28 - x

Simplify

4x = 28

Divide Both Sides By 4

4x / 4 = 28 / 4

x = 7

The asymptote for the given exponential function shown in the graph is line r. Option b is correct.

What is an asymptote?

An asymptote is a straight line or curve that a graph approaches but never touches. Asymptotes can occur in various types of graphs, including functions, equations, and curves. In a function, an asymptote can occur when the function approaches a certain value as the input variable approaches infinity or negative infinity.

Here,

Asymptotes can be vertical, horizontal, or slanted, and they can occur on either side of the graph. Asymptotes are important in mathematical analysis, as they can help determine the behavior of a function or equation as the input variable increases or decreases without bounds.

So, the asymptote for the given exponential function shown in the graph is line r. Option b is correct.

Answers

Answer:

See below

Step-by-step explanation:

15)

In the right-angle triangle, once one of the angles is 44º, then, the unknown angle is [tex]x[/tex].

[tex]180 = 44 + 90 + x[/tex]

[tex]180 = 134 + x[/tex]

[tex]x= 46[/tex]

The angle [tex]y[/tex] of the other triangle plus the angle [tex]x[/tex] of the right-angle triangle is equal to 90º, therefore they are complementary angles.

So,

[tex]90 = x + y[/tex]

[tex]90 = 46 + y[/tex]

[tex]y=44[/tex]

To find ?, we have

[tex]180 = 58 + 44 +?[/tex]

[tex]180 = 58 + 44 +?[/tex]

[tex]? =78[/tex]

16)

The sum of the internal angles of the triangle with angles 50º and 25º is equal to 180º, therefore, the other angle is

[tex]180 = x + 50 + 25\\180 = x+ 75\\x=105[/tex]

Once the angles are opposite, they are the same. For the triangle with the 36º angle, we have

[tex]180 = 36 + 105 + y[/tex]

[tex]180 = 141+ y[/tex]

[tex]y=39[/tex]

[tex]?=39[/tex]

After triangle ACE is dilated by a factor of 6, it has an area of 180 square inches. What was its area before dilation?

Answers

Answer:

The area of triangle ACE before dilation is:  30 square inches

Step-by-step explanation:

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

If the scale factor > 1, the image is enlarged If the scale factor is between 0 and 1, it gets shrunk If the scale factor = 1, the object and the image are congruent

The length of the image can be determined by multiplying the length of the original point by a certain scale factor.

Given that after triangle ACE is dilated by a factor of 6, it has an area of 180 square inches.

Thus, it means the dilated area is 6 times the area before dilation.

Let x be the pre-dilation area

As the dilated area is 6 times the area before dilation, so

6x = 180

divide both sides by 6

6x/6 = 180/6

x = 30 square inches.

Therefore, the area of triangle ACE before dilation is:  30 square inches

HELP IM STUCK ON THIS QESTION!!!

Answers

Answer: 3.81

Step-by-step explanation:

Answer:

3.81

Step-by-step explanation:

1. We assume, that the number 25.4 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 25.4 is 100%, so we can write it down as 25.4=100%.

4. We know, that x is 15% of the output value, so we can write it down as x=15%.

5. Now we have two simple equations:

1) 25.4=100%

2) x=15%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

25.4/x=100%/15%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 15% of 25.4

25.4/x=100/15

(25.4/x)*x=(100/15)*x       - we multiply both sides of the equation by x

25.4=6.66666666667*x       - we divide both sides of the equation by (6.66666666667) to get x

25.4/6.66666666667=x

3.81=x

x=3.81
