Answer:
Hi there!
Your answer is:
81
Step-by-step explanation:
First, simplify within parentheses.
-4-3-2 = -7-2 = -9
(-9)^2
The negative is within the parentheses, so it goes away when squared
(-9)^2 = -9× -9= 81
Hope this helps
The x-coordinate of the solution. 1
Answer:
y=-3/2x-1
Step-by-step explanation:
First, we convert the equation into slope-intercept form, so that we can make it easier to find the equation of the perpendicular line. Multiply 2/3 by both x and 3, and you get y-3=2/3x+2. Now we subtract 3 from both sides to get y by itself. We are now left with y=2/3x-1. To find the reciprocal of an equation, you look at the slope (in this case it is 2/3) and you find the opposite reciprocal of it. Basically, we take 2/3 and we flip it and change the sign. The equation we are left with is y=-3/2x-1. We didn't use the x-intercept because it wasn't necessary in this case.
Answer:
no solutions
Step-by-step explanation:
6-3x=4-x-3-2x
Combine like terms
6-3x =1 -3x
Add 3x to each side
6 -3x+3x = 1-3x+3x
6 =1
This is not true so there are no solutions
