Step-by-step explanation:
they are complementary, they add to 90
The equations classified according to the number of solutions are given as follows:
- No solution: -3(3q + 4) = -6q + 12
- One solution: -2(3n - 4) = -6n - 4
- Infinitely many solutions: 8z - 4 = 8z - 4
<h3>How many solutions does the equation 4(2z - 1) = 8z - 4 has?</h3>
We solve the equation, hence:
4(2z - 1) = 8z - 4
8z - 4 = 8z - 4
Equivalent, hence they have infinitely many solutions.
<h3>How many solutions does the equation -2(3n - 4) = -6n - 4 has?</h3>
-2(3n - 4) = -6n - 4
-6n + 8 = -6n - 4
0 = -12, which is false, hence it has no solutions.
<h3>How many solutions does the equation -3(3q + 4) = -6q - 12 has?</h3>
-3(3q + 4) = -6q + 12
-9q - 12 = -6q + 12
3q = -24
q = -8.
One solution.

Answer:
Step-by-step explanation:
The depreciation of the value for a car is modeled by the equation y = 100,000(.85)^x for x years since 2000
a) for the value to be $61,412.50, then
61412.50 = 100000(.85)^x
61412.50/100000 = 0.85^x
0.614125 = 0.85^x
We would take log to base 10 of both sides. It becomes
Log 0.614125 = log 0.85^x =
x log0.85
- 0.2117 = x × - 0.07058
- 0.2117 = - 0.07058x
x = - 0.2117/- 0.07058
x = 3 years
b) 1/4 × 100000 = 25000
Therefore ,
25000 = 100000(.85)^x
25000/100000 = 0.85^x
0.25 = 0.85^x
We would take log to base 10 of both sides. It becomes
Log 0.25 = log 0.85^x =
x log0.85
- 0.602 = x × - 0.07058
- 0.602 = - 0.07058x
x = - 0.602/- 0.07058
x = 9 years
