Answer:

y = x²+ 5

Step-by-step explanation:

When your line is curved, you know that is will be an x² and the slope intercept is 5 so that's what goes at the end and its a postitive5 as well.      

Complete question :

kim and jay leave at the same time to travel 25 miles to the beach. kim drives 9 miles in 12 minutes. jay drives 10 miles in 15 minutes if they both continue at the same rate, who will arrive at the beach first?

Answer:

KIM

Step-by-step explanation:

Given that:

Distance traveled = 25 miles

Kim :

9 miles in 12 minutes

Rate = distance / time

Rate = 9 / 12 = 0.75 miles per minute

Jay:

10 miles in 15 minutes

Rate = distance / time

Rate = 10 / 15 = 0.667 miles per minute

Since Kim's rate is higher than Jay's rate, Kim will arrive at the beach faster than Jay.

0.75 > 0.667

Kim will arrive first

Answer:

The slope of the line is 19

Step-by-step explanation:

slope=(y2-y1)/(x2-x1)=(27-(-30))/(39-36)=57/3=19

Therefore, the slope of the line is 19

Answer:

16

Step-by-step explanation:

there are four gallons

1=4 quartz

so u multiply

4 x 4 = 16

4=16

Total of all frequencies:

5+8+1213+11= 49

Divide the frequency of 59-61 by total frequencies:

13/49 = 0.265 which rounds to 0.27

The answer is 0.27

Answer:

Only two are correct;

a) The electrician charges an initial fee of $42

b) The electrician charges $22 for every hour worked

Step-by-step explanation:

Here, we want to select all possible correct options;

Kindly understand that the equation of a straight line can be represented in the form;

y = mx + c

where m is the slope and c is the y-intercept (where x = 0)

1. The electrician charges an initial fee of $22

This is wrong. $22 represents the slope and it indicates a rate of change and not an initial fee

2. The y-variable represents the number of hours

This is wrong. What the y-variable represents is the amount charged in US dollars

3. The electrician charges an initial fee of $42

This is correct. The y-intercept value is the value when x is zero

4. The electrician charges $22 for every hour worked

This is correct. From the equation, 22 represents the change which is the slope

It is the amount charged per hour

5. The x-variable represents the electrician’s charges in dollars

This is wrong. As we can see from the question, the x-variable represents the number of hours

6. The electrician charges $42 for every hour worked

This is wrong. What $42 represents is the charge at 0 hour which means the charge at x = 0

Answer:

The equation which represents the given formula written in terms of P is  

P = 9/5 * C + 32

Step-by-step explanation:

Seems the question is: Which of these equations represents the given formula written in terms of P. If so, we will make P the subject of the given formula.

C = 5/9 * (P - 32)

This can be written as

[tex]C = \frac{5}{9} \times (P-32)[/tex]

Multiplying both sides by 9, we get

[tex]9 \times C = 9 \times \frac{5}{9} \times (P-32)[/tex]

[tex]9C = 5 \times (P - 32)\\[/tex]

Now, divide both sides by 5, we get

[tex]\frac{9C}{5} = \frac{5 \times (P - 32)}{5}[/tex]

This gives

[tex]\frac{9}{5} \times C = P - 32[/tex]

Now, Add 32 to both sides of the equation

[tex]\frac{9}{5} \times C + 32 = P - 32 + 32[/tex]

This becomes

[tex]\frac{9}{5} \times C + 32 = P[/tex]

Hence

[tex]P = \frac{9}{5} \times C + 32[/tex]

That is,  P = 9/5 * C + 32

Hence, the equation which represents the given formula written in terms of P is  P = 9/5 * C + 32.

Answer:

[tex]\boxed{\frac{23}{3} ~in}[/tex] or [tex]\boxed{7,7~in}[/tex]

.

Step-by-step explanation:

Suppose, the first side is a, the second side is b, and the third side is c. So:

→ a = s - 4

→ b = s

→ c = (s - 4) + 3

→ a + b + c = 15

First step, find the value of s

a + b + c = 15

(s - 4) + s + (s - 4) + 3 = 15

3s - 5 = 15

3s = 15 + 5

3s = 20

[tex]s = \frac{20}{3}[/tex]

So, the third side is

c = (s - 3) + 4

c = s + 1

c = [tex]\frac{20}{3} + 1[/tex]

[tex]c = \frac{23}{3}[/tex]

.

Answer:

The answer is the second option 4.8

Step-by-step explanation:

I just did the test.

The distance between the point JM will be; 4.81 units.

The centroid of a planar figure or firm figure, also known as the point of intersection or center of the figure, is the mean absolute position of all of the other points on the subject's surface.

The centroid of the triangle is given by;

(x, y) = [(x₁ + x₂ + x₃) / 3, (y₁ + y₂ + y₃) / 3]

Given that the coordinates J(7, 8), K(1, 2) and L(5, 2) for △JKL. Then the centroid for △JKL is at point M is given;

(x, y) = [(7 + 1 + 5) / 3, (8 + 2 + 2) / 3]

(x, y) = (13/3, 12/3)

(x, y) = (13/3, 4)

Therefore, the distance between the point JM is calculated as given;

D² = (13/3 - 7)² + (4 - 8)²

D² = 7.1111 + 16

D² = 23.11

D = √23.11

D = 4.81 units

The distance between the point JM will be; 4.81 units.

More about the centroid of the triangle link is given below.

Step-by-step explanation:

Answer:

A factor of f(x) is (x + 1).

Step-by-step explanation:

When we put x+1= 0 then we  get the value x= -1

This value is then put into the function to find out whether it is a root or not. For a root  to exist it must not have a remainder or the remainder must be zero.

Suppose the function is

F(x)= 2x³ - 42x - 40

f(-1)= 2(-1)³ - 42(-1) - 40

f(-1)= -2 + 42- 40

f(-1)= 0

This gives -1 as the root of the function.

Answer:

C. 7 weeks.

Step-by-step explanation:

Since the shrub was 64 cm tall at first, take away 64 from 76.6. Now we are left with 12.6. Let's divide 12.6 by 1.8 (that's how many cm it grows per week). When we do this, we are left with 7. This means it took 7 weeks for the shrub to reach 76.6 cm. I hope this helps!
