Solve the literal equation for the given variable<br> n =4/5(m+7); m
Step2247 [10]

Answer:

<h2>m =  \frac{5n}{4}  - 7</h2>

Step-by-step explanation:

<h2>n =  \frac{4}{5} (m + 7)</h2>

First of all multiply both sides by 5

That's

<h3>5n = 5 \times  \frac{4}{5} (m + 7) \\ 5n = 4(m + 7)</h3>

<u>Next divide both sides by 4</u>

That's

m + 7 =  \frac{5n}{4}

Subtract 7 from both sides to make m stand alone

We have

<h3>m + 7 - 7 =  \frac{5n}{4}  - 7</h3>

We have the final answer as

<h3>m =  \frac{5n}{4}  - 7</h3>

Hope this helps you

The function f(x) = –x2 − 2x + 15 is shown on the graph. What are the domain and range of the function?
Phantasy [73]

Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.

Domain: ( − ∞ , ∞ ) , { x | x ∈ R }

Range: ( − ∞ , 16 ] , { y | y ≤ 16 }
