Answer:
y+4 = 2(x+3)
Step-by-step explanation:
We have 2 points so we can find the slope
m = (y2-y1)/ (x2-x1)
= (2--4)/(0--3)
= (2+4)/(0+3)
= 6/3
= 2
We want to use the point slope form of the equation for a line
y-y1 = m(x-x1)
We know the slope =2 and the point (0,2)
y-2 = 2(x-0)
y-2 = 2x
We could also use the other point (-3,-4)
y--4 = 2(x--3)
y+4 = 2(x+3)
The complete question in the attached figure
we know that
[<span>amount of fabric]=8*[area of lateral triangle side]
area of lateral triangle side=(1/2)*4*5----> 10 ft</span>²
so
[amount of fabric]=8*[10]----> 80 ft²
the answer is80 ft²
Answer:

Step-by-step explanation:
In order to solve this, we are trying to find the value of
. Basically,
is a placeholder for a number that is unknown. Some number minus 3 is equal to 21.
Our goal is to find
. To do this we want to isolate
on one side of the equation

Let's add 3 to both sides.

Hope this helped!
Answer:

Step-by-step explanation:
The midline is set on
, when the sine function is equal to zero, eliminating the effect from amplitude. The midline is a horizontal line. Hence, the equation of the midline is:

The answer is 49 because since she multiplied 5 by 7 you have to do the same to yellow marbles so 7×7 = 49
