Y = 1/2x + 4 x - y = 8 *Substitution

Mathematics

Answer:

y=16, x=24

Step-by-step explanation:

First simplify: x-(1/2x+4)=8

Isolate x for 1/2x-4=8

Add 4 to both sides:

1/2-4+4=8+4

Simplify :1/2=12

Multiply both sides by 2:

2*1/2x=12*2

Simplify:

x=24

Substitute x=24:

y=1/2*24+4

1/2*24+4=16

1/2*24=12

12+4

Add the numbers: 12+4=16

y=16

The solutions to the systems of equations are:

y=16,x=24

PLEASE HELP ME!!! I NEED HELP WITH GEOMETRY QUESTION ASAP!! DESPRATLY
BartSMP [9]

Answer:

The answer to your question is:      y = -3x + 14

Step-by-step explanation:

Data

A (4, 2)

y = x/3  - 1

Perpendicular

original slope = 1/3

perpendicular slope = -3

Equation                 (y - y1) = m(x - x1)

                               (y - 2) = -3(x - 4)

                               y - 2 = -3x + 12

                               y = -3x + 12 + 2

                               y = -3x + 14
