True
<h3>
Answer:</h3>
- x-intercept: 82.75
- y-intercept: -2.15
<h3>
Step-by-step explanation:</h3>
To find the x-intercept, set y=0 and solve.
... 0 = log(12x +7) -3
... 3 = log(12x +7) . . . . add 3
... 1000 = 12x +7 . . . . take the antilog. (10^3 = 1000)
... 993 = 12x . . . . . . . .subtract 7
... 82.75 = x . . . . . . . . divide by 12
To find the y-intercept, set x=0 and solve.
... y = log(12·0 +7) -3
... y = log(7) -3 . . . . . . simplify
... y ≈ 0.85 -3 = -2.15 . . . . use a calculator for the log function

Step-by-step explanation:
Percent means out of 100
20% = 20/100 which can be simplified
20/100 Divide by 10 on top and bottom
=2/10 Divide by 2 on top and bottom
= 1/5
80% = 80/100 which can be simplified
80/100 Divide by 10 on top and bottom
= 8/10 Divide by 2 on top and bottom
=4/5
15% = 15/100 Which can be simplified
15/100 Divide by 5 on top and bottom
= 3/20
