Solve for the indicated variable in the literal equation

ANTONII [103]

Answer:

$x = \frac{y}{3} - \frac{5}{3}$

Step-by-step explanation:

Given

$y = 5 + 3x$

Required

Solve for x

Subtract 5 from both sides

$y-5 = 5 -5+ 3x$

$y-5 = 3x$

Divide through by 3

$\frac{y}{3} - \frac{5}{3} = x$

$x = \frac{y}{3} - \frac{5}{3}$

4/7<br> of a number is 36<br> What is the number?

katrin [286]

$\text{If the number is x,}\\\\~~~~~\dfrac 47 \cdot x =36\\\\\implies 4x = 36 \times 7\\\\\implies x =\dfrac{36 \times 7}4\\ \\\implies x = 9 \times 7\\\\\implies x = 63\\\\\text{Hence, the number is 63.}$

If f(x)f(x) is an exponential function where f(-1)=5f(−1)=5 and f(7)=32f(7)=32, then find the value of f(4)f(4), to the nearest

Whitepunk [10]

Using an exponential function, it is found that the value of the function when x = 4 is of f(4) = 15.95.

<h3>What is an exponential function?</h3>

It is modeled by:

$y = ab^x$

In which:

a is the initial value.

b is the rate of change, as a decimal.

In this problem, we have that f(-1)=5, hence:

$5 = ab^{-1}$

$\frac{a}{b} = 5$

a = 5b

We also have that f(7)=32, hence:

$32 = ab^7$

Since a = 5b:

$5b^8 = 32$

$b = \sqrt[8]{\frac{32}{5}}$

b = 1.2612.

a = 5b = 5 x 1.2612 = 6.306.

Hence the function is given by:

$y = 6.306(1.2612)^x$

Then, when x = 4, we have that:

$y = 6.306(1.2612)^4 = 15.95$
