Hello!
You can solve this algrbraically
2/3 x = -20
Multiply both sides by 3
2x = -60
Divide both sides by 2
x = -30
The answer is B) -30
Hope this helps!
Answer:
y = e^x - 4
Step-by-step explanation:
The missing options are
y = ln x - 3
y = ln x - 4
y = e^x - 3
y = e^x - 4
The function is defined in quadrant 3 and increases exponentially, then it is not a logarithm.
f(x) crosses the y-axis at (0, -3). Replacing x = 0 the last option, we get:
y = e^0 - 4 = 1 - 4 = -3

Answer: 0.05x+10</h3>
Work Shown:
x = number of miles
Cost of company A = 0.09x+50.50
Cost of company B = 0.14x+60.50
Subtract the two expressions (B-A) to find the difference in price
B-A = (0.14x+60.50)-(0.09x+50.50)
B-A = 0.14x+60.50-0.09x-50.50
B-A = (0.14x-0.09x) + (60.50-50.50)
B-A = 0.05x+10
Answer: x = 3
Step-by-step explanation:
2(7x - 6) = 30
14x - 12 = 30
+ 12 +12
14x = 42
/14 /14
x = 3
