Answer:

7

Step-by-step explanation:

Comparing the two similar triangles

JK/MN = JL/MP

25/30 = 20/(4X - 4)

CROSS MULTIPLY

25(4X - 4) = 30 × 20

100X - 100 = 600

COLLECTING LIKE TERMS

100X = 600 + 100

100X = 700

DIVIDING THROUGH BY 100

X = 700/100

X = 7

Yuhhhhhhhhhelp plss
KatRina [158]

Answer:

-8

Step-by-step explanation:

Your equation is: -4x-y=24

Your given coordinates are: (   , 8)

Here you are given the y value. So you can substitute that into your equation to find x.

-4x-8=24

Add 8 on both sides

-4x=32

Divide by -4

x=-8

So your final coordinate is (-8,8)

Find the vertex of y=-x^2+6x-12
Debora [2.8K]
You find the x coordinates using x = -b/2a  = -6/2(-1) = 3

Substitute 3 in the equation and find y

y = -(3^2) + 6(3) - 12 = -9 + 18 - 12 = -3

Vertex (3,-3)
