Answer:
Step-by-step explanation:
For the first one you need to go along the ‘corridor ‘ and up the stairs. So you go along the x axis to find -1 then you go up to 2. Once you’ve found all the points graph line them up and then you times the sides to find the area
Answer:
-2
Step-by-step explanation:
change in y divided by change in x
4÷-2 = -2
Hey!
~Set up the equation: -5(x-1)=40
~ Divide 5 on both sides: 40/-5
~ Simplify: x-1=-8
~ We want to get x by itself, so subtract +1 to both sides.
~ Simplify: x = -7
~ Therefore, x = -7.
Answer:
1/2n - 11 = -25
Hope this helps you! Have a good night!
Also, n = -28
1/2n - 11 = -25
1/2n - 11 + 11 = -25 + 11
1/2n = -14
1/2n / 1/2 = -14 / 1/2
n = -28
Check:
1/2(-28) - 11 = -25
-14 - 11 = -25
-25 = -25
X² + x + ...m
x² + x + 1/4
\/x² = x
\/(1/4) = 1/2
2*x*1/2 = 2x/2 = x
x² + x/2 + 1/4
