The slope of the line passing through(-2,5) and (4,-1) is:

Lady bird [3.3K]

Answer:

The slope of the line passing through (-2, 5) and (4,-1) is -1.

Step-by-step explanation:

To solve this equation, we can use the formula Δy÷Δx=s.

(Change in y divided by change in x is equal to slope)

First, plot the two points on a graph, then draw a line connecting the two points.

Then, draw a line from (-2,5) to (-2,-1). Since the line goes down by 6 units from (-2,5), this means that the change in y is -6.

Draw a line from (-2,5) to (4,5). Since the line goes right by 6 units from (-2,5), this means that the change in x is +6.

Δy÷Δx=s

-6÷6=s

-6÷6=-1

-1=s

Therefore, the slope of the line passing through (-2, 5) and (4,-1) is -1.

Find the length of AB. A. 2 B. 6 C. 21 D. 31

Allushta [10]

Answer

AB=21

Solution

In the triangle ABC two lines are parallel to side AC.In a triangle a line passing through two side and it is parallel to third side,then this line divides two side in equal ratio.

Here we take any of the parallel line, passing through AB and AC, and parallel to BC.

So we can write, $\\$ $\frac{ 6x+2x+1}{2x}$ = $\frac{18+7.5}{6}$

8x+1=6x+2.5x

x=1/0.5

x=2

Therefore AB = 6x+2x+1+2x =10x+1=21

1/2(4x+10)=2 i need to get x

kari74 [83]

First you need to distribute the 1/2 by the numbers in the parentheses
1/2•4x and 1/2•10 which equals
2x+5=10

next, you will need to get the 2x by itself so you would do
2x+5=10
-5=-5
2x=5

finally, you divide the 2 by the 5 so you can get the x by itself
2x divided by 5

the answer is: x=2.5

Dafna1 [17]

So, to turn this into a percentage, we have to turn this into a decimal by dividing:
80/100 = 0.80
80% of tart cherries are produced in this state.
