when you multiply exponents, they add together and the base will remain the same:
-5+-2
=-7
therefore the answer is 8^-7
to get rid of the negative, flip the fraction so it becomes
1/8^7
Answer:
2.5
Step-by-step explanation:
I used the process of elimination :
For A and B, you can't have a negative number since it is a positive correlation
For C, 1 as a slope isn't reasonable
Answer:
y= -2/3x-2
Step-by-step explanation:
Since we have a point and a slope, we can use the point slope formula

m is the slope. In this case, m is -2/3
y1 is the y coordinate of the point. In this case, it is -2
x1 is the x coordinate. In this case it is 0.
We can substitute these values into the formula
y- -2= -2/3(x-0)
Distribute -2/3
y+2 = -2/3*x + -2/3*0
y+2= -2/3x+0
Subtract 2 from both sides. We want to get y by itself. This is because we want our line to be in y=mx+b form.
y+2-2= -2/3x+0-2
y= -2/3x -2
Answer:
x=3
Step-by-step explanation:
Step 1: Add two to 7 and inverse the minus 2
3x=7+2 3x=9
Step 2: Divide each number by 3.
3x/3=x and 9/3=3
so x=3
