Answer:
x=7
Step-by-step explanation:
x=7
12 - x = 5
12 - 7 = 5
Answer:
Length: 12, Width: 6
Step-by-step explanation:
The width, or w is 1/2 the length, so the length is 2w
So, we can set up the equation 2w+2w+w+w, or 6w=36
So, w=6, and you can plug into the length
Answer:
y= (-1)*x
Step-by-step explanation:
lets assume that the line equation is
y=m*x +b
where m is the slope and b the independent variable that intercept Y axis.
then replacing the value of m:
y=(-1)*x + b
after that we have to look for the value of b. Its obtained replaicing the given point (8,-8):
-8 = (-1)*(8) +b
-8 = -8 + b
0 = b
Therefore the equation of the line is:
y= (-1)*x
The answers D
Step-by-step explanation:
the answer is D because to fine slope, you have to do rise over run
hope this help : )
Goal: Try to get the variable by itself!
5n+4=-26
-4= -4
5n=-30
n=-6
