Answer:

m = 7

Step-by-step explanation:

- 3(12 - m) = - 1(m - 8)

- 36 - (- 3m) = - m - 8

- 36 + 3m = - m - 8

- 36 + 3m + m = - m + m - 8

- 36 + 4m = - 8

- 36 + 36 + 4m = - 8 + 36

4m = 28

4m ÷ 4 = 28 ÷ 4

m = 7

Three squares of sides 15 units, 9 units, and 12 units can form a

right-angled triangle.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

Given, We have to form a right-angled triangle that has side lengths of

3 different squares.

Let, The first square has a side length of 9 units, and let this be the height of the right-angled triangle.

Another square has a side length of 15 units and this is the hypotenuse.

Therefore, the base of the triangle must be 15² - 9² = 225 - 81 = 144 = 12 units.

So, The third square must have a side length of 12 units.

0.1x + 0.3 = 0.5 ( subtract 0.3 from both sides )

0.1x = 0.2 ( divide both sides by 0.1 )

Given:

Dimensions of the rectangular table are 40 inches by 25 inches.

To find:

The length of the diagonal of the table.

Solution:

Diagonal of a rectangle is:

[tex]d=\sqrt{l^2+w^2}[/tex]

Where, l is the length and w is the width of the rectangle.

Putting [tex]l=40,w=25[/tex] in the above formula, we get

[tex]d=\sqrt{(40)^2+(25)^2}[/tex]

[tex]d=\sqrt{1600+625}[/tex]

[tex]d=\sqrt{2225}[/tex]

[tex]d\approx 47.17[/tex]

Therefore, the length of the diagonal is about 47.17 inches.

Answer:

x = 289 degrees

Step-by-step explanation:

The sum of angle measures in a hexagon is 720 degrees. One can apply this information here, by forming an equation. Add up all of the angle measures, including parameter (x), simplify and use inverse operations to solve for the numerical value of the parameter (x).

100 + 102 + 108 + 121 + x = 720

Simplify,

431 + x = 720

Inverse operations,

431 + x = 720

-431        -431

x = 289

Given:

The histogram of a survey that represents the amount of electricity used by residents in a local community.

To find:

The approximate number of participants in the survey.

Solution:

Using the given histogram, we get the frequency table:

Electricity usage              Frequency

          50                                 23

         150                                 34

        250                                 25

        350                                 26

        450                                 42

Sum of frequencies is:

[tex]23+34+25+26+42=150[/tex]

It means the total number of participants in the survey is 150.

Therefore, the correct option is (a).

2 Answers:

Parallel lines always have equal slope, but different y intercepts.

==========================================================

Explanation:

Let's solve the second equation for y

3y - x = -7

3y = -7+x

3y = x-7

y = (x-7)/3

y = x/3 - 7/3

y = (1/3)x - 7/3

The equation is in y = mx+b form with m = 1/3 as the slope and b = -7/3 as the y intercept. We see that the first equation, where y was already isolated, also has a slope of m = 1/3. The two equations of this system have the same slope. Choice C is one of the answers.

However, they don't have the same y intercept. The first equation has y intercept b = -4, while the second has b = -7/3. This means that they do not represent the same line. They need to have identical slopes, and identical y intercepts (though the slope can be different from the y intercept of course) in order to have identical lines. So we can rule out choice D and E because of this.

Because the two equations have the same slope, but different y intercepts, this means the lines are parallel. Choice B is the other answer.

Parallel lines never touch or intersect, which in turn means there is no solution point. A solution point is where the lines cross. We can rule out choice A.

I recommend using your graphing calculator, Desmos, GeoGebra, or any graphing tool (on your computer or online) to graph each equation given. You should see two parallel lines forming. I used GeoGebra to make the graph shown below.

Step-by-step explanation:

Answer:

The distance is [tex]\sqrt{20}[/tex] or [tex]2\sqrt{5}[/tex].

Step-by-step explanation:

Slope of parallel: 2

Slope of perpendicular: -1/2

Pick a point for y =2x + 7. For example (0,7)

Use the perpendicular slope to get to the other line to find the other point of y=2x-3. Look at the screenshot...I got (4,5).

Distance formula [tex]\sqrt{(x_{2}-x_{1} )^{2}+(y_{2} -y_{1})^2 }[/tex]

Insert (0,7) and (4,5)

[tex]\sqrt{(0-4)^{2}+(7-5)^2 }[/tex] = [tex]\sqrt{(-4)^{2}+(2)^2 } = \sqrt{(16)+(4)} } = \sqrt{20} = 2\sqrt{5}[/tex]

The distance between parallel lines whose equations are y = 2x + 7 and y = 2x – 3 is [tex]2\sqrt{5}[/tex] and can be determined by using the point-slope form and also by using the distance formula.

Given :

First, determine the line perpendicular to the line (y = 2x + 7) whosw slope is -1/2 and intersect the line (y = 2x + 7) at point (0,7).

Using the point-slope, the equation of the perpendicular line can be determined.

[tex](y-y_1)=m(x-x_1)[/tex]    ---- (1)

where m is the slope and [tex](x_1,y_1)[/tex] is the point on the line.

Now, put the value of known terms in the equation (1).

[tex]y-7=-\dfrac{1}{2}(x-0)[/tex]

y = -0.5x + 7   --- (2)

Now, determine the point of intersection between lines (y = -0.5x + 7) and (y = 2x -3).

Substitute the value of y that is (y = 2x - 3) in equation (y = -0.5x + 7).

2x - 3 = -0.5x + 7

2.5x = 10

x = 4

Now, put the value of x in the equation (y = -0.5x + 7).

y = -0.5(4) + 7

y = 5

Now, the distance between two points is given by the equation:

[tex]\rm D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]\rm D = \sqrt{(0-4)^2+(7-5)^2}[/tex]

[tex]\rm D = \sqrt{20}[/tex]

[tex]\rm D = 2\sqrt{5}[/tex]

The distance between parallel lines whose equations are y = 2x + 7 and y = 2x – 3 is [tex]2\sqrt{5}[/tex].
