Answer:
-5.5
Step-by-step explanation:
f(x) = (x-1). f(-4.5) = (-4.5-1). f(-4.5) = -5.5
Answer: $31.99
Step-by-step explanation:
So, it is originally $39.99, so first we convert 20% to a decimal, which is 0.2.
Then we do 39.99 * 0.2 to find how much money was taken off.
39.99 * 0.2 = 7.998, or $8
Now, we do the original dollar amount, $39.99, minus the discount, $8, which equals $31.99.
Slope Formula:
m= Y2-Y1/X2-X1
m= 8-12 / 3-2
m= -4/ 1
m= -4
Therefore, the equation of the line is y=-4x+20
The square root of 150 is 12.2474487139. The square root of 136 is 11.6619037897. And your welcome :)
The problem can be translated into an equation that is something like 4/5 + 3/x = 1/2
we cannot have x equal to zero because the number can be infinite.
So the LCD here is 10x, so multiply both sides by that to get:
8x + 30 = 5x
Subtract 5x and 30 from both sides:
3x = -30
divide:
x = -10
The solution isn't zero so there is a solution.
