Rus_ich [418]

value of x = -1 and value of y=8

Step-by-step explanation:

We need to solve the system of equations:

$4x - 3y = -28\,\,\,(1)\\x + 5y = 39\,\,\,(2)$

Multiply eq(2) with 4 and subtract with eq(1)

$4x-3y=-28\\4x+20y=156\\-\,\,\,-\,\,\,\,\,\,\,\,\,\,\,\,\,\,-\\--------\\-23y=-184\\y=\frac{-184}{-23}\\y=8$

So, value of y=8

Now, finding value of x by putting value of y in equation 2

$x+5y=39\\x+5(8)=39\\x+40=39\\x=39-40\\x=-1$

So, value of x = -1

value of x = -1 and value of y=8

Triangle JKL has vertices J(−2, 2) , K(−3, −4) , and L(1, −2) . Write the coordinate notation for a translation of 8 units right

Dovator [93]

Triangle JKL has vertices J(−2, 2) , K(−3, −4) , and L(1, −2) .

Rule: (x, y)→(x + 8, y + 1 )

J’ (-2, 2) → (-2 + 8, 2 + 1 ) → (6, 3 )
K’ (-3, -4) → (-3 + 8, -4 + 1 ) → (5, -3 )
L’ (1, -2) → (1 + 8, -2 + 1 ) → (9, -1)

J’ (6,3)
K’ (5,-3)
L’ (9,-1)

Hope this helps!
