Answer:
G (4 , -4)
Area CDEF : 176
Step-by-step explanation:
CD ⊥ x axis
FE ⊥ x axis
Point G (x , y) x = 4 and y = -4
G (4 , -4)
CD = 5 + 4 = 9
FE = 7 + 6 = 13
DG = 12 + 4 = 16
Area CDEF = (Cd + FE) x DG / 2 = (9 + 13) x 16 /2 = 176
Step 1) simplify the constants, so basically you are doing the 3-4 part and turning the equation in -8x-1>-1
Step 2) isolate the variable, first you need to add 1 to both sides to cancel it off then the equation is -8x>0. Next you divide both sides by -8, don't forget that when you multiply or divide by a negative you need to flip the sign which makes the equation x<0 because when you divide 0 by any number it is still 0
Hope this helped!

Step-by-step explanation:
<u>Step 1: Define</u>
2x + 4y = 24
y = -3
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in <em>y</em>: 2x + 4(-3) = 24
- Multiply: 2x - 12 = 24
- Isolate <em>x</em> term: 2x = 36
- Isolate <em>x</em>: x = 18
