X = 15 and Y = -3 because X + Y = 12
X - Y = 18
__________
2X = 30
X = 15
15 + Y = 12
Y = -3
You can substitute the X value into either equation from the first two equations

Find the distance between<br> (-3,5) and (4,-2)
Westkost [7]

Answer:

7√2 or approx. 9.89949

Step-by-step explanation:

distance between two points is

d=√(∆x^2+∆y^2)

where...

d is distance

∆x is change in x value

and ∆y is change in y value

In this problem ∆x=(-3)-4=(-7)

∆y=5-(-2)=7

plugging in those values gives us

d=√((-7)^2+7^2)

Solving this expression gives us

d=√(49+49)=√98

After simplifying the radical we are left with 7√2 or about 9.89949.

What is the distance between the points (3,-7) and (6,2)
kotykmax [81]

Answer:

Step-by-step explanation:

Use the distance formula to determine the distance between the two points.

Distance

=√(x2−x1)2+(y2−y1)2

Substitute the actual values of the points into the distance formula.

√(2−(−3))2+((−6)−(−7))2

Simplify.
