Answer:

<h2>96 mi</h2>

Step-by-step explanation:

t=2\dfrac{2}{3}\ h=\dfrac{2\cdot3+2}{3}\ h=\dfrac{8}{3}\ h\\\\r=36\ mph\\\\\text{Substitute to}\ d=rt:\\\\d=36\!\!\!\!\!\diagup^{12}\ \dfrac{mi}{h\!\!\!\!\diagup}\cdot\dfrac{8}{3\!\!\!\!\diagup_1}\ h\!\!\!\!\diagup=(12\ mi)(8)=96\ mi

7n+2 = 4n+17 solve the equation
lions [1.4K]

Answer:

n = -5

Step-by-step explanation:

Solve for n:

n + 2 = 4 n + 17

Hint: | Move terms with n to the left hand side.

Subtract 4 n from both sides:

(n - 4 n) + 2 = (4 n - 4 n) + 17

Hint: | Combine like terms in n - 4 n.

n - 4 n = -3 n:

-3 n + 2 = (4 n - 4 n) + 17

Hint: | Look for the difference of two identical terms.

4 n - 4 n = 0:

2 - 3 n = 17

Hint: | Isolate terms with n to the left hand side.

Subtract 2 from both sides:

(2 - 2) - 3 n = 17 - 2

Hint: | Look for the difference of two identical terms.

2 - 2 = 0:

-3 n = 17 - 2

Hint: | Evaluate 17 - 2.

17 - 2 = 15:

-3 n = 15

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -3 n = 15 by -3:

(-3 n)/(-3) = 15/(-3)

Hint: | Any nonzero number divided by itself is one.

(-3)/(-3) = 1:

n = 15/(-3)

Hint: | Reduce 15/(-3) to lowest terms. Start by finding the GCD of 15 and -3.

The gcd of 15 and -3 is 3, so 15/(-3) = (3×5)/(3 (-1)) = 3/3×5/(-1) = 5/(-1):

n = 5/(-1)

Hint: | Simplify the sign of 5/(-1).

Multiply numerator and denominator of 5/(-1) by -1:

Answer: n = -5

Determine whether the rule represents an exponential function. Explain why or why not.
Alenkasestr [34]

Answer:

Yes.

Step-by-step explanation:

Exponential Parent Function: f(x)= a(b^{x})

If we write out the equation:

y = 6(5)^{x}

Whenever we have an exponent of <em>x</em>, it is a exponential function. The 5 is simply the base of the exponent and the 6 means we are vertically stretching the graph by a factor of 6.
