Answer:

Option 1:[tex]y = -\frac{2}{3}x+5[/tex] is the correct answer.

Step-by-step explanation:

The slope-intercept form of a line is given as:

[tex]y = mx+b[/tex]

Here m is the slope and b is the y-intercept

m is calculated using the formula

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Given points are:

[tex](x_1,y_1) = (-3,7)\\(x_2,y_2) = (9,-1)[/tex]

Putting the values in the formula

[tex]m = \frac{-1-7}{9+3}\\= \frac{-8}{12}\\=\frac{-2}{3}[/tex]

Putting m=-2/3 in equation

[tex]y= -\frac{2}{3}x+b[/tex]

Putting (9,-1) in equation

[tex]-1 = -\frac{2}{3}(9)+b\\-1 = -6+b\\b = -1+6\\b = 5[/tex]

Putting the value of b

[tex]y = -\frac{2}{3}x+5[/tex]

Hence,

Option 1:[tex]y = -\frac{2}{3}x+5[/tex] is the correct answer.

Shawn wanted to rent a mo-ped for the afternoon. The rental fee for a mo-ped was $10 plus $7 for each hour he used the bike. Write an expression that represents the cost for h hours. Then, decide how much Shawn spent if he rented the mo-ped for 3 hours.

Answers

Answer:

Total cost= $31

Step-by-step explanation:

Giving the following information:

The rental fee for a mo-ped was $10 plus $7 for each hour he used the bike.

First, we need to structure the total cost formula:

Total cost= 10 + 7h

h= number of hours

Now, for 3 hours:

Total cost= 10 + 7*3

Total cost= $31

Answer:

The y-intercept is (0, 5) and the x-intercept is (2.5, 0).

What is an intercept of the straight line?

In the context of a straight line in a two-dimensional plane, an intercept refers to the point(s) where the line intersects with one or both of the coordinate axes (i.e., the x-axis and the y-axis).

To find the y-intercept, we set x = 0 and solve for y:

-4(0) + 7 = 2y - 3

7 = 2y - 3

2y = 10

y = 5

Therefore, the y-intercept is (0, 5).

To find the x-intercept, we set y = 0 and solve for x:

-4x + 7 = 2(0) - 3

-4x + 7 = -3

-4x = -10

x = 2.5

Therefore, the x-intercept is (2.5, 0).

Manuel and Felicia are comparing how much
money they have
• Manuel has $250.
• He saves $150 per week,
• Felicia has $1,650.
• She spends $200 per week.
• Let x = the number of weeks
• Let y = the amount of money at the end
of the week.
Which system of equations represents this
situation?

Answers

Answer:

y = 250 + 150xy = 1650 - 200x

Step-by-step explanation:

Equation for Manuel:

y = 250 + 150x

Equation for Felicia:

y = 1650 - 200x

Solving we get:

250 + 150x = 1650 - 200x150x + 200x = 1650 - 250350x = 1400x = 1400/350x = 4 weeks

and

y = 250 + 150*4 = 250 + 600 = $850

After 4 weeks Manuel and Felicia will have equal amount of money- $850

Answer:

1. x = 102. x = -63. 944. x = 2

Step-by-step explanation:

1. F and M are equal angles and sum of internal angles = 180, so

2(7x + 5) + 30 = 18014x + 10 + 30 = 18014x = 140x = 10

2. Triangle is equilateral as all angles are equal, so all sides are equal:

4x + 43 = -2x + 74x + 2x = 7 - 436x = -36x = -6

3. Isosceles triangle with equal angles of R and T:

4x + 7 = 7x - 20  (using values as per picture not text)7x - 4x = 20 + 73x = 27x = 9

Angle S is

180 - 2(4*9 + 7)= 180 - 2(43) = 180 - 86 = 94

4. Angle 2 is supplementary with 156 as isosceles triangles and vertical angles are equal, therefore:

180 - 156 = 6 + 9x24 = 6 + 9x18 = 9xx = 2

What similarity property, if any, can be used to show that the following two triangles are similar.

Answers

They both have right angles and have the same angles overall. Essentially they are the same size, one is just expanded bigger than the other. It might be dilation. The inside line so indicate the similarity in angle sizes.

Answer:

The angles

Step-by-step explanation:

On both triangles, there is a square in the corner which means that both angles are 90 degrees, and then on the left side of the triangle, there are two signs that are the sames meaning those two have the same angle measurement. Based on this knowledge I know that the last angle of the triangle must also be the same degrees since both triangles follow the same equation 90+a+b=180. I know that all angle measurements from one triangle must equal 180. So these are the same triangles with different sizes.

Answer:

y= - 21/17

Step-by-step explanation:

Rearrange terms:

2(15+6y) +5y =9

2(6y+15)+5y=9

Distribute:

2(6y +15) +5y=9

12y+30 + 5y = 9

Combine like terms:

Approximately how much principal would need to be placed into an account earning 1.58% interest compounded monthly so that it has an accumulated value of $90,597 at the end of 25 years?

Answers

Answer:

The initial investment is $821.58

Step-by-step explanation:

Giving the following information:

Future Value (FV)= $90,597

Number of periods (n)= 25*12= 300

Interest rate (i)= 1.58% = 0.0158

To calculate the initial investment, we need to use the following present value (PV) formula:

PV= FV/(1+i)^n

PV= 90,597 / (1.0158^300)

PV= $821.58

The initial investment is $821.58

Uniforms are sold in packages of 8. The store's 137 employees will each be given 4 uniforms. How many uniforms will the store need to order all together?

Answers

Answer:

552 uniforms (69 packages)

Step-by-step explanation:

since each employee will be given 4 uniforms and each package contains 8 uniforms, you need 1 package of uniforms for every 2 employees.

Total number of employees = 137

total number of uniform packages = 137 / 2 = 68.5 packages which must be rounded up since you need to have enough uniforms for everyone = 69 packages

69 packages x 8 uniforms per package = 552 uniforms

Chet started to slow his eating speed down later in the evening. He was
now eating only 1/4 of a turkey every 2 hours. What was his unit rate
later in the evening?

Answers

Answer:

The unit rate is:

1/8 turkey/per hour.

Step-by-step explanation:

As Chet was eating 1/4 of a turkey every 2 hours.

This tells us that every two hours, Chet will eat  175  1/4 of a turkey.

Unit rate basically means 'how much of something per 1 unit of something else'.

A unit rate is a rate with a denominator of  1  unit.

This means, in 1 hour, Chet will eat half of what he eats every 2 hours.

so Chet will eat [tex]\frac{\frac{1}{4}}{2}=\frac{1}{8}[/tex] of a turkey in 1 hour.

i.e.

[tex]\frac{\frac{1}{4}}{2}=\frac{1}{8}[/tex]

Therefore, the unit rate is:

1/8 turkey/per hour.

Familial Acromegaly is caused by an increased amount of growth hormones that are produced during our adulthood and are secreted from our pituitary gland which is located in our brain. Acromegaly is extremely rare to be passed down each generation, when it is, its due to a part of multiple endocrine neoplasia type 1 (MEN1), or a condition called familial isolated pituitary adenoma. Acromegaly is distinguished by enlarged features such as your face, hands, and feet. As the face might change shape due to the excess hormones your jaw may protrude or extend out to a certain point, your nose might get longer, and your lips might get fuller or thicken (basically you might have/get Cardi B-like lips). Familial acromegaly can cause puberty to hit much later, and cause genitalia to possibly be deformed due to the increased growth hormones.
