Answer:
Step-by-step explanation:
Since perimeter, 
and we know that P=2(l+w) then 
The length will be 
Now 
Answer: The equation is y= -2x -4
Step-by-step explanation:
The slope intercept form is like y=mx+b so we know the slope which is m but we just need to find the y intercept.
and we will use the given coordinates to find the y intercept by putting in the x and y coordinates into the formula y=mx + b
-6= -2(1) + b
-6= -2 + b
+2 +2
b= -4
Answer:
12 (i think)
Step-by-step explanation:
so you see the problem the first problem is 3x-9. and you see 27
then you multiply 12 by 3 and you get 36 then you minus 36 by 9 and you get 27
Hi i wanted to help you but i hate math do i am soooooooo sorry
Answer:
D. H = 2.1t + 12
Step-by-step explanation:
Let us assume the t be the time in minutes
And h be the water level
Now before reaching to the equation that need to be used
before this, determine the inches per minute i.e.
= 54 inches - 12 inches
= 42 inches in 20 minutes.
Now for per minute, it would be
= 42 inches ÷ 20 minutes
= 2.1 inches per minute
After this, multiply the inches per minute with the minutes t and add the sale to the beginning value i.e. 12
So the equation is
H = 2.1t + 12
hence, the last option is correct
