Let f(x) = y.
y = 4x - 12
Let x = 0
y = 4(0) - 12
y = - 12
This leads to the point (0, -12).
Let y = 0.
0 = 4x - 12
1 2 = 4x
12/4 = x
3 = x
This leads to the point (3, 0).
We now graph both points and then connect each point with a straight line.
We know there is a total of 100 cups of tea sold and that there are two types of teas involved.
x = tea 1
y = tea 2
We can set up two equations and use substitution to solve:
x + y = 100 cups of tea sold total
One of the teas sold 5 times as much as the other. Let's believe that this was tea 1:
x = 5y (5 times as much means multiplication, and 'other' means y)
If x = 5y, then this must be true for the first equation. So we'll test this by plugging it in:
5y + y = 100
6y = 100
y = about 16.67
Now we can use this number to solve for x in the original equation:
x + 16.67 = 100
x = 83.33
Answer:
3/-2
Step-by-step explanation:
All I did was put - 3/2 into my calculator and got the answer. I than found the answer for the rest of the fractions and only the first one equals to - 3/2.
