Answer: The total cost to paint the mural will be $80.
First, we need to find the area of the trapezoid. The formula is one-half times the height times the sum of the bases.
0.5 x 6 (9 + 11) = 60 m^2
Each can will cover 12 m^2, so divide 60 by 12 to find that we need 5 cans.
The cost of each can is $16, so 5 x 16 = $60.
Note that mailing address is unique, but houses are not, meaning that you can't have house A and house B both referencing the same address.
So, in order to have a valid function, any two points on the function cannot have the same x value that lands on different y.
With this property mentioned, it's clear to see that
(house, address) is NOT a function; however, (address, house) is a function, since same x lands on multiple y values is a valid onto function. (a house that have multiple addresses)
Answer:
20
Step-by-step explanation:
u make a proportion and solve for x:
294/12 = 490/x
12 x 490 = 5880
5880/294 = 20
Answer:
x = 2
Step-by-step explanation:
The relevant rule of logarithms is ...
log(a/b) = log(a) -log(b)
This lets us combine the logs on the left to get ...
log((6 +7x)/(3x -2)) = log(5)
Taking anti-logs gives ...
(6 +7x)/(3x -2) = 5
6 +7x = 5(3x -2) . . . . . multiply by (3x -2)
7x +6 = 15x -10 . . . . . eliminate parentheses
8x = 16 . . . . . . . . . . . add 10-7x to both sides
x = 2 . . . . . . . . . . . . . divide by 8
The solution is x = 2.
_____
The graph shows the left side of the equation is equal to the right side for x=2.
(-1,-2) and (3,3) will be the coordinates to your problem.
