Answer:
2 equivalent expressions w/ negative signs in different places.
a)
=-1/5 x and x/-5
b)
=14/-y and -14/1/y
c)
=a/1/b and 1/b/1/a
d)
=-c/y and -c/1/y
Answer:
No solution
Step-by-step explanation:
- 4x - 4y = 1
- 4x - 4(x + 2) = 1
- 4x - 4x - 8 = 1
- - 8 = 1
Our end result is -8 = 1. This is not true, so this system of equations have no solution.
Answer:, 49.010000.
Step-by-step explanation:
3y = -2x + 2
y = x + 4 (Substitute the y)
3(x + 4) = -2x + 2 (Distribute)
3x + 12 = -2x + 2 (Add 3 to both sides)
+3x +3x
------------------------------------------
12 = 1x + 2 (Subtract 2 from both sides)
-2 - 2
------------------------
10 = 1x (Divide by 1 on both sides)
10/1 = 1x/1
x = 10
This is your x-coordinate
A.
the area of a polygon is/
A= perimeter X apothem /2
A=500
apothem = 10
500 = (P * 10)/2
P =100
B. 100*7.95 = $795
C.
60*100= 6,000
6,000 * $7.95=
