Answer:
A
Step-by-step explanation:
If you substitute each x value from the input boxes into the equations, you can find your answer.
The first input value is 1, and the output value is 12, so plug those into the first equation in the answer options.
y = 4x + 8
(12) = 4(1) + 8
12 = 4 + 8
12 = 12
Because the simplified equation ended in a true equality statement, that pair works with the equation.
The next x value is 3 and the y value is 20:
y = 4x + 8
(20) = 4(3) + 8
20 = 12 + 8
20 = 20
Again, it ends in true equality statement, so it also works with the equation.
(28) = 4(5) + 8 = 28 so that one works as well.
Then check the second equation with the second set of input and output values.
(2) = -7(-1) - 5 = 2
The first x and y values of that system work.
(9) = -7(-2) - 5 = 9
The second one works as well.
(16) = -7(-3) - 5 = 16
The last one is equal as well.
So the equations in A, or the first option, work with all of the inputs and outputs.
93,688 square feet need to be painted.
ceiling = 14*18= 252
width wall = (18*11)*2= (198)*2
length wall = (14*11)*2= (154)*2
308+396+252=956 square ft. for one room
956*98=93,688 square feet.
In 5 years one California Palm tree grew = 85 inches.
Then in 1 year the California palm tree grew = (85/5) inches
= 17 inches
Again
A queen palm tree in 8 years grew = 96 inches
In 1 year the queen palm tree grew = (96/8) inches
= 12 inches.
So the California palm tree is growing at a faster rate than the queen palm tree. This is the easiest way of solving this kind of problems. Hope that i have explained the problem enough for you to understand and attempt such problems in the future without anyone's help.
