Answer:
The value of the computer is given by 
.
Step-by-step explanation:
A computer sells for $900.
If the price of the computer loses 30% of its value per year, then it is compounded every year.
Now, the price of the computer t years after it is sold will be
........... (1)
Therefore, the value of the computer is given by the above equation (1). (Answer)
Answer:
x > 7
Step-by-step explanation:
0.8 - 3.2x < -2 - 2.8x
Add 2.8x to both sides.
0.8 - 0.4x < -2
Subtract 0.8 from both sides.
-0.4x < -2.8
Divide both sides by -0.4. Remember that when you multiply or divide both sides of an inequality by a negative number, the inequality symbol changes direction.
x > 7
Answer:
a. (0,5) and (4,0)
b. -5/4
c. y = -5/4x + 5
Step-by-step explanation:
The intercepts are where the line crosses the axis. It crosses at (0,5) and (4,0).
The slope of the line is how much it rises over how much it runs. It rises -5/4 from each intercept to the other.
The linear equation should be written as y = mx+b where b = 5 and the slope -5/4.
So the equation is y = -5/4x + 5.
