Hi there!
To solve this problem, we need to multiply each number by 4 ft.
8×4=32
5×4=20
Now, we films the area.
32×20 = 640
The area of the room is 640 feet squared.
Hope this helps!
Answer:
P = ( 4y + 6 inches) + ( 8y - B ) inches + ( 5y + 3 ) inches
Step-by-step explanation:
Formula of Perimeter of triangle is = Sum of all sides.
P = A + B + C
Answer:
y>-3 y>-7
Step-by-step explanation:
-(y+5)>2
y<-7
To find if one is a function, you must see if the pattern is the same.
Domains (x) can not have two values
I forget what the y value is called, but there can be the same y- value for multiple x - values
A. is not a function, because its ordered pairs are all over the place, and the value 4 in the x - value has two values assigned - 0 and 3, which makes it invalid.
B. may be a linear function. Its ordered pairs aren't jumping all over the place.
Both the x and y go up one for one, so the function could be y = x + 3
C. isn't because the x - value 2 has two values. Again, that makes this invalid.
D. is invalid because there is two x - values for 2.
Therefore, the answer is B.
The point-slope form of the equation of the line is:
(y - y1) = m (x - x1)
So, (y + 2) = - 1/3 (x - 4) in the point-slope form is:
[y - (-2) ] = (-1/3) [ x - 4 ]
You must, then realize that the line passes through the point (4,-2) and its slope is - 1 /3.
That slope, -1 / 3, means that the function is decresing (because the slope is negative), and it decreases one unit when x increases 3 units.
Now you can fill in the blanks in this way:
Plot the point (4, -2), move 1 unit down, and 3 units over to find the next point on the line.
