Answer:

2,-1

Step-by-step explanation:

graph, find length between points (sqrt 20) and slope (-2). sqrt20/2=sqrt5.

change in y/change in x = -2, change in y squared + change in x squared= 5. solve system of equations to get x=1, y=-2, or x=-1, y=2. i think i did something wrong but the answer should be correct

What is the value of s in the equation 3 r equals 10 plus 5 s, when r equals 10? 4 8 100 200

alisha [4.7K]

Answer

<h2>4</h2>

Step-by-step explanation:

Given,

r = 10

Let's create an equation,

$3r = 10 + 5s$

plugging the value of r

$3 \times 10 = 10 + 5s$

Multiply the numbers

$30 = 10 + 5s$

Move 5s to L.H.S and change its sign

Similarly, Move 30 to R.H.S and change its sign.

$- 5s = 10 - 30$

Calculate

$- 5s = - 20$

The difference sign ( - ) should be cancelled on both sides

$5s = 20$

Divide both sides of the equation by 5

$\frac{5s}{2} = \frac{20}{5}$

Calculate

$s = 4$

The value of s is 4.

Hope this helps..

Best regards!!
