X-Intercept is found by setting y to = 0.
<span>Y-intercept is found by setting y to =0.</span>
Answer:
1,080
Why:
First. you have to turn the feet into inches which would make the room 120in. by 144in. and the area of the room would be 17,280 square inches.
Then you have to find the area of the square tiles, and since the sides of the square are the same length , 4x4=16
Last, you have to divide 17,280 by 16 which would give you 1080 tiles
Answer:
width is 4 meters
Step-by-step explanation:
A = l*w where l is length and w is width
28 = 7*w
Divide each side by 7
28/7 = 7w/7
4 =w
Rewrite (1st) equation
-x - 2y = - 9
multiply the (1st) equation by 3
-3x - 6y = -27
now you have
-3x - 6y = -27
3x - 6y = -15
-----------------------add
-12y = -42
y = 3.5
2(3.5) = -x + 9
7 = - x + 9
x = 2
answer
(2 , 3.5)
