If the range of the function f(x) = 7x – 2.7 is {14.1, 30.9, 41.4, 58.9, 68}, what is its domain?

Drupady [299]

domain is {2.4, 4.8, 6.3, 8.8, 10.1 }

For domain, equate f(x) to each value in the range and solve for x

7x - 2.7 = 14.1 ⇒ x = $\frac{x14.1 + 2.7}{7}$ = 2.4

7x - 2.7 = 30.9 ⇒ x = $\frac{30.9 + 2.7}{7}$ = 4.8

7x - 2.7 = 41.4 ⇒ x = $\frac{41.4 + 2.7}{7}$ = 6.3

7x - 2.7 = 58.9 ⇒ x = $\frac{58.9 + 2.7}{7}$ = 8.8

7x - 2.7 = 68 ⇒ x = $\frac{68 + 2.7}{7}$ = 10.1

Solve the exponential equation 1/2^x-5=8^x

dexar [7]

$( \frac{1}{2} ) {}^{x - 5} = 8 {}^{x} \\ 2 {}^{ - x + 5} = 2 {}^{3x} \\ - x + 5 = 3x \\ - 4x = - 5 \\ x = \frac{ - 5}{ - 4} = \frac{5}{4}$

Gas costs $2.05 per gallon. You go on a trip of 150 miles and your car gets 25 miles per gallon. How much will you spend on gas?

Inessa05 [86]

Answer: 12.30 dollars will be spent

Step-by-step explanation: If you go on a trip of 150 miles and each mile is 25 miles per gallon, I divided 150 miles from 25 = 6. Then each gallon cost $2.05 dollars, if we want to know how much will they spend on gas you have to multiply how much per mile and how much it cost. So 2.05 times 6 = 12.30.
