-7 = x/2 + 1
Subtract one from both sides
-8 = x/2
Multiply two on both sides
-16 = x
Answer, x = -16
Checking,
-7 = (-16/2) + 1
-7 = -8 + 1
-7 = -7
Point form: (3,4)
Multiply each equation by the value that make the coefficients of x opposite:
(-4)•(3x-4y)=(-4)(-7)
(3)•(4x+3y)=(3)(24)
Simplify:
-12x+16y=28
12x+9y=72
Add the two equations together to eliminate x from the system:
-12x+16y=28
+12x+9y=72
———————
25y=100
Cancel out the common factor of 25 and divide 100 by 25:
25 100
—- = ——
25 25
100

25 Y=4
To find x:
Substitute the value found for y into one of the original equations to find x:
-12x+16(4)=28
Multiply 16 by 4:
-12x+64=28
Subtract 64from 28
-12x=-36
Now cancel out the common factor of -12 ,then divide -36 by -12 which would be x=3
Answer:
150 This is right 4sure i did this test to.
Step-by-step explanation:
I believe that the quadrilateral formed would be a kite. With the diagonal that forms 2 congruent triangles being from point (0,9) to (0,1)
Steps:
1) 4,000 * .045 = 180
2) 180 * 6 = 1,080
3) 4,000 + 1,080 = 5,080
4)4,000 * .049 = 196
5) 196 * 6 = 1,176
6) 4,000 + 1,176 = 5,176
7) 5,176 - 5,080 = $96
Answer= $96
