Jar has vertices j(1,4) a(3,5) and r(2,1) if you reflect jar across the y-axis what will be the coordinates of the vertices of the image j1 a1 r1

see explanation

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y) → (- x, y), thus

J(1, 4) → J'(- 1, 4)

A(3, 5) → A'(- 3, 5)

R(2, 1) → R'(- 2, 1)

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
