Point G is the midpoint of PQ. PG equals 2X plus 3 and GQ equals 5X -5. what is X?

Mathematics

borishaifa [10]3 years ago

Answer:

x=\frac{8}{3}=2\frac{2}{3}\approx{2.667}

Step-by-step explanation:

\overline{PG}=2x+3\\\overline{GQ}=5x-5

Since they're equidistant (equal distances), we can set them equal to one another and solve for x:

2x+3=5x-5

Adding 5 to both sides:

2x+8=5x

Subtracting 2x from both sides:

8=3x

Dividing both sides by 3:

\frac{8}{3}=x

Therefore:

x=\frac{8}{3}=2\frac{2}{3}\approx{2.667}

Line CD passes through points C(3, -5) and D(6, 0). What is the equation off three line CD in standard form?
Alina [70]
Standard form: Ax+By=C
first put in slope-intercept form:
slope = (0+5)/(6-3) = 5/3
pick point D: 0 = 5/3(6)+b -> b= -10
slope-intercept form: y=(5/3)x-10
multiply both sides by 3:
3y=5x-30
put in standard form:
5x-3y=30

Hey there! :D

Remember that the question said estimate. 

So 

47% rounds to 50% 

.5 and 1/2 are equal to 50% 

89 rounds to 90. 

You could say that:

1/2*90

0.5*90

90/2 

These will all work and will give you the same answer. 

I hope this helps!

Graph a line with a slope of -3 that contains the points (4,-2)
Lera25 [3.4K]

Answer:

  see below for a graph

Step-by-step explanation:

To draw a graph on a grid, locate the point (4, -2) and use the slope to find another point. One such point will be 1 to the left and up 3*, at (3, 1). With two points, you can draw the line through them to complete the graph.

__

For a graphing tool that requires an equation, the point-slope form of the equation can be used:

  y -k = m(x -h) . . . . . a line of slope m through point (h, k)

For the given slope and point, the equation of the line is ...

  y +2 = -3(x -4)

  y = -3x +10

_____

* The slope is "rise" over "run". The slope of -3 means that a <em>run</em> of +1 will result in a <em>rise</em> of -3. The given point is already below the x-axis, so we don't really want to find more points farther down. In order to go up on a line with negative slope, we must choose a point to the left of the given one.

Find the solution to the systems of equations using the elimination method. 3x + 5y = 2 5x + 8y = 4
Irina-Kira [14]

Answer:

\boxed{x = 4~~and~~y = -2}

Step-by-step explanation:

3x + 5y = 2 (times 5) 15x + 25y = 10

5x + 8y = 4 (times 3) 15x + 24y = 12

.

15x + 25y = 10

<u>15x + 24y = 12 </u>  <u>  </u>

y = -2

.

Substitute the value of y to one of equations

3x + 5y = 2

3x + 5(-2) = 2

3x - 10 = 2

3x = 2 + 10

3x = 12

x = \frac{12}{3}

x = 4
