Equation R: -3y = -3x - 9
Equation S: y = x + 3
Replace y in Equation R with equation S:
-3(x+3) = -3x - 9
Use distributive property:
-3x -9 = -3x -9
Because both sides of the equation are identical x can be any number and they would still be equal.
This means there are Infinite solutions.
Answer:
f. 85
Step-by-step explanation:
<u>All triangles add up to 180 degrees</u>
BCE=25
then you need to find DBC, you can do that since ABD is isocilies that means all sides are equal in length and angle so 180 divided by 3 (number of side) is 60
isoceles triangle have 2 sides that are equiangular, cince we know BCA is 25 we also know BAC is 25, leaving angle ABC to be 130 (180-50=130)
we subtract angle ABD from angle ABC to get angle DBC, leaving angle DBC to equal 70 degrees
since 70 (angle DBC) + 25 (Angel BCA)= 95
we just subtrract 95 from 180 to get the answer 85 (:
The third option can be represented by a linear function, y = -8x + 6.
Answer:
Step-by-step explanation:
This only works if the room is a prism shaped, or cylinder.
Volume of a prism or cylinder is area of he base times height. So since we know the height and volume we can fand the area.
V = h*B
B = V/h
B = 400/25
B = 8
This is a very narrow room, anyway, the area of the base, which we want to carpet is 8 square meters. Can you figure out how much it will cost since each square meter will cost 5?
