Answer:

1st Option;

j = 4.5

k = 2

Step-by-step explanation:

Let's solve for "j" first:

=> We know that by the definition of midpoint segment theorem we can say;

3j = 5j - 9

0 = 5j - 3j - 9

0 = 2j - 9

0 + 9 = 2j

9 = 2j

9/2 = j

4.5 = j

=> Now that we have j-value we use the same method to solve for k-value;

6k = k + 10

6k - k = 10

5k = 10

k = 10/5

k = 2

Therefore;

j = 4.5

k = 2

So the first option would be correct!

Hope this helps!

Answer:

y = 10

Step-by-step explanation:

Given y varies inversely as x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

To find k use the condition x = 4 when y = 15 , then

15 = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )

60 = k

y = [tex]\frac{60}{x}[/tex] ← equation of variation

When x = 6 , then

y = [tex]\frac{60}{6}[/tex] = 10

Answer:

36.87( round if needed(

Step-by-step explanation:

we know a side adjacent to the angle and opposite of the angle so we apply tangent function

[tex] \tan(x) = \frac{3}{4} [/tex]

[tex] \tan {}^{ - 1} ( \frac{3}{4} ) = 36.87[/tex]

Round if neededd

Answer:

Indeed, the given triangle is a right triangle.

Step-by-step explanation:

A triangle is formed by the following three points: [tex]A(x,y) = (x_{1}, y_{1})[/tex], [tex]B(x,y) = (x_{2}, y_{1})[/tex] and [tex]C(x,y) = (x_{2}, y_{2})[/tex]. Then, we construct the following vectors:

[tex]\overrightarrow {BA} = (x_{2}-x_{1}, y_{1}-y_{1})[/tex]

[tex]\overrightarrow{BA} = (x_{2}-x_{1}, 0)[/tex] (1)

[tex]\overrightarrow{BC} = (x_{2}-x_{2}, y_{2} - y_{1})[/tex]

[tex]\overrightarrow{BC} = (0, y_{2}-y_{1})[/tex] (2)

If triangle ABC is a right triangle, then [tex]\overrightarrow{BA}\,\bullet\,\overrightarrow{BC} = 0[/tex]. By (1) and (2) we have this expression:

[tex](x_{2} - x_{1})\cdot (0) + (0)\cdot (y_{2} - y_{1}) = 0[/tex]

Therefore, the given triangle is a right triangle.

The equation that represents the number of hours, h, Erica rented the scooter is 25h + 12 = 73.

Consider variable h represents the number of hours Erica rented the scooter.

The term 25h represents the cost of the gas fee, which is $25 multiplied by the number of hours.

The term 12 represents the cost per hour of renting the scooter.

The equation states that the sum of the gas fee and the rental fee per hour equals the total cost of $73.

Therefore, the correct equation is:

25h + 12 = 73, which represents the number of hours Erica rented the scooter.

Answer:

28 cups of coffee

Step-by-step explanation:

We can start by converting so that the two numbers have the same denominator. 4 2/3 as an improper fraction is 14/3. Then, you would multiply the  top and bottom by 2 which is 6. So, your new fraction is 28/6, which is equal to 4 2/3. Divide by 28/6 by 1/6 to get 28.

Its C

Step-by-step explanation:

Answer:

Part A: one solution:

Part B: x = 3, y = 4.

1) Part A: how many solutions does the pair of equations for lines A and B have?

The solution of a system of equations in a graph is given by the intersetion of the curves that represent the equations.

In this case, there are two straight lines, which intersect in one and only one point.

Hence, the system has one solution.

2) Part B: what is the solution to the equations of lines A and B?

The solution is the pair of coordinates of the intersection point. It is (3, 4).

Therefore, the solution is x = 3, y = 4.
