Answer:
24x^7 = 24x^7
Step-by-step explanation:
Left side of equation: 3 times 8 times X = 24x
Then you raise it to the 7th power
Right side of the equation: 6 times 4 times X = 24x
Since the exponent is the same, you keep it as the 7th power
Start at (0,0) go to the right 5 spaces then go up 4 spaces. put a point where you end up
1.50*12 = $18
18 < 1800 so that is not true, she made a mistake.
First let's get rid of the x by multiplying the tip equation by -2
-2 (-6x - 2y = -4)
+
(-12x - 5y = -13)
Distribute
(12x + 4y = 8)
+
(-12x - 5y = -13)
x cancels out and you're left with
-1y = -5
y = 5
Now solving for x, plug in your y into one of the equations
-6x - 2(5) = -4
-6x - 10 = -4
-6x = 6
x = -1
(-1 , 5) is the solution
