<h3>Correct Question :</h3>

Four times a number minus 5 is equal to three times the number plus 9. Find the number.

<h3>Solution :</h3>

Let the required number be x.

Atq,

\implies (4  \times x) - 5 = (3 \times x)  + 9 \\ \implies 4x - 5 = 3x  +  9 \\ \implies 4x - 3x = 9 + 5 \\ \implies x = 14

\therefore{\green { The\:required\: number \:is\: 14.}}

What is the slope of a line that is perpendicular to the line<br> v= -1/3x - 6
Amiraneli [1.4K]

Answer:

3

Step-by-step explanation:

the slope of a perpendicular line is the negative reciprocal of the original slope

a reciprocal is the inverse of a number, to find the reciprocal, just flip the numerator and denominator

in this cause, the slope is -1/3

the negative of it is 1/3 and the reciprocal is 3

therefore the slope of the perpendicular line is 3

What is the inverse of the following statement? If m is the midpoint of PQ, then PM is congruent to QM
stepan [7]

The inverse of the statement is M be the point on PQ since PM is congruent to QM than M is midpoint on the PQ.

<h3>What do you mean by inverse?</h3>

Inverse of the statement means that explain the condition in reverse way or vice versa.

Since, M is the midpoint of PQ, then PM is congruent to QM.
Proving in reverse way, let m be the point between P and Q the distance M from P is equal to the distance from M to Q. Which implies that M lies as the mid of the P and Q.

Thus, the inverse of the statement is M be the point on PQ since PM is congruent to QM than M is midpoint on the PQ.

Need help please help me

The solution is the point of intersection between the two equations.

Assuming you have a graphing calculator or a program to lets you graph equations (I use desmos) you simply put in the equetions and note down the coordinates of the point of intersection.

In the graph the first equation is in blue and the second in red.

The point of intersection = the solution = (-6 , -1)



If you dont have access to a graphing calculator you could draw the graphs by hand;

1) Draw a table of values for each equation; you do this by setting three or four values for x and calculating its image in y (you can use any values of x)

y = 0.5 x + 2 (Im writing 0.5 instead of 1/2 because I find its easier in this format)

x | y
-1 | 1.5 * y = 0.5 (-1) + 2 = 1.5
0 | 2 * y = 0.5 (0) + 2 = 2
1 | 2.5 * y = 0.5 (1) + 2 = 2.5
2 | 3 * y = 0.5 (2) + 2 = 3

y = x + 5

x | y
-1 | 4 * y = (-1) + 5 = 4
0 | 5 * y = (0) + 5 = 5
1 | 6 * y = (1) + 5 = 6
2 | 7 * y = (2) + 5 = 7

2) Plot these point on the graph
I suggest to use diffrent colored points or diffrent kinds of point markers (an x or a dot) to avoid confusion about which point belongs to which graph

3) Using a ruler draw a line connection all the dots of one graph and do the same for the other

4) The point of intersection is the solution

what is the equation, in point-slope form, of the line that is perpendicular and passes through the point (−4, 3)?
inn [45]
A perpendicular line has a slope of infinity. Therefore it is not possible to write the equation in point-slope form.
The equation is x = -4.
