Answer:

10 hour rental

Step-by-step explanation:

Let x = number of hours

HD cost: 7x + 65

L cost: 4x + 95

Set the two cost expressions equal and solve for x, the number of hours.

7x + 65 = 4x = 95

3x = 30

x = 10

The costs are equal for a 10 hour rental.

Solve 4e^2x-3=12 please help
Anestetic [448]

4*e^{2x} -3 = 12

Step 1:

Here we have -3 in subtraction on the left side, so when we take it to the right we apply opposite operation of subtraction that is addition.

4*e^{2x} = 12+3

4*e^{2x} = 15

Step 2:

Next we have 4 in multiplication on left side, so dividing right side by 4,

e^{2x} = 15/4

e^{2x} = 3.75

Step 3:

taking log on both sides

ln ( e^{2x}) = ln(3.75)

{2x} =ln 3.75

Step 4:

Dividing right side by 2,

x= ln (3.75) /2 = 0.66088

Answer : x = 0.66088..

Write an inequality for the given statement: The sum of x and 25 is less than 75.
Kaylis [27]
That statement would be best express by " x + 25 < 75 ". Since the statement says the sum of x and 25, thus, it will be x + 25. Then it also states that the sum is less than 75, so the best expression would be " < 75".
