Answer:
g(x) = Negative two-fifths(10)x
Step-by-step explanation:
In order to reflect a function over the x-axis, you have to multiply the function by minus one.
Given the function:
f(x) = 2/5(10)^x
Its reflection over the x-axis is:
-f(x) = -2/5(10)^x = g(x)
The final bill is $544
The parts is a one time bill of $265
The labor is $48 per hour, and lets call the hours 'h'
So we can make the equation as:
544 = 265 + 48h
Subtract 265 n both sides
279 = 48h
Divide by 48 on both sides
h = <span>5.8125
So the number of hours of labor spent repairing the car is </span><span>5.8125.</span>
Answer:
The answer is 90 inches
Step-by-step explanation:
Answer:
AB = 2×2=4, 3×3=9, 4×4=16, 5×5=25
is the right answer
Let the length of segment AB be x.
BC then is AB + 6 or x + 6.
AC is AB + BC - 13 or x + x + 6 - 13 = 2x - 7
The sum of the three lengths is 78.
x + x + 6 + 2x - 7 = 78
4x - 1 = 78
4x = 79
x = 19.75
BC = x + 6 = 19.75 + 6 = 25.75
Answer: B. 25.75 mm
