Answer:

Step-by-step explanation:

We need to solve the equation .The given equation is ,

→ 8 - 6x = -28

→ -6x = -28-8

→ -6x = -36

→ x = -36/-6

→ x = 6

<h3>• Hence the value of x is 6 .</h3>

the slope of the line below is -3. use the coordinates of the labeled point to find a slope-point equation of the line. (5,-7)

HACTEHA [7]

$\bf (\stackrel{x_1}{5}~,~\stackrel{y_1}{-7})~\hspace{10em} slope = m\implies -3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-7)=-3(x-5) \\\\\\ y+7=-3x+15\implies y=-3x+8$

The point A(5.

NeX [460]

The point (6, 6) is the mid-point of A and B. Then the coordinate of the point B is (7, 5).

<h3>What is coordinate geometry?</h3>

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Point A (5, 7) is reflected over the point (6, 6) and its image is point B. Then the point (6, 6) is the mid-point of the A and B. Then the coordinate of the point B will be

$\rm (x_2 , y_2) = (2x -x _1, 2y - y_1)\\\\(x_2 , y_2) = (2 \times 6 - 5, 2 \times 6- 7)\\\\(x_2 , y_2) = (12-5,12-7)\\\\(x_2 , y_2) = (7, 5)$

More about the coordinate geometry link is given below.

a plumber uses the expression 48+25h to determine the number of dollars to charge each customer. If h=4, how much does the custo

Elis [28]

Answer:

$148

Step-by-step explanation:

We are given the expression:

48+25h

We are also given h=4. Since we know what h is equal to, we can substitute 4 in for h.

48 + 25h (h=4)

48 + 25(4)

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

First, multiply 25 and 4.

48+ (25*4)

48+100

Next, add 48 and 100

48+100

148

The customer will have to pay $148

A car is traveling at a speed of 108 kilometers per hour. What is the cars speed in kilometers per minute? How many kilometers w

cluponka [151]

The distance travelled by the car will be 3.6km in 2 minutes.

<u>Explanation:</u>

Given:

Speed, s = 108 km/hr

s in km/min = ?

1 hr = 60 min

So,

108 km/hr = $\frac{108}{60} km/min$

= 1.8 km/min

time, t = 2 min

Distance, d = ?

We know:

distance = speed X time

$d = 1.8 X 2\\\\d = 3.6km$

Therefore, the distance travelled by the car will be 3.6km in 2 minutes.

A car travels 14km in 25mins . Find out how far the car can travel in 5 hours if the speed remains the same ?

jekas [21]

<h3><u>Answer :- </u></h3>

168 km ...

<h3><u>Explanation :- </u></h3>

It is given that the car travels 14km in 25 minutes..

Now , assume that the distance the car travel in 5 hours be x..

Since 1 hour = 60 minutes..
5 hours = 300 minutes ..

• Thus , The two given statements are :-

14km -----------------> 25 minutes..
And, x km -------------> 300 minutes..

The distance travelled by car and the time taken by the car is directly proportional to each other....

$\frac{14}{25} = \frac{x}{300}$

$= x = 168km$

• Hence , Car can travel 168km in 5 hours ..

Hope this helps you :)
