Remember with area you multiply all the sides so figure out the lengths of the other sides and multiply :)
Answer:
y=-1/2x-1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-4-0)/(6-(-2))
m=-4/(6+2)
m=-4/8
simplify
m=-1/2
y-y1=m(x-x1)
y-0=-1/2(x-(-2))
y=-1/2(x+2)+0
y=-1/2x-2/2+0
y=-1/2x-1
Answer:
i'll give you answer.Dont worry. Since i came back from school
Answer:144
Step-by-step explanation:
X+6+ X+6+ X+6+ X+6
4x+24
Get the x alone so you divide the 4 on both sides.
24/4=6
X=6
Area
(X+6)(X+6)
X=6 Plug to the Equation So it looks like this
(6+6=12)(6+6=12)
12x12=144
Answer 144
In exponent form It would look like this
Answer:
Step-by-step explanation:
x=# of boys, y=# of girls
after 24 boys have left, we have 3 times as many girls
y=3(x-24)
because there are the same number of girls as boys - we create this equation
x=y
then we can use substitution
y=3(y-24)
y=3y-72
-2y=-72
y=36
because there are 36 boys, that means there are also 36 girls - leaving you with 72 children in the beginning.
hope this helps!!
