Answer: 57%
Step-by-step explanation:
Davis's monthly expenditure and his monthly salary was 3 : 7.
This means that for every $7 he received, he spent $3 out of it.
The amount he saved is therefore:
= 7 - 3
= $4
For every $7 received, he saved $4.
Percent = 4/7
= 57%

Topic: Fraction and relations:
<u><em>Your domain (Input to a fraction, usually known as your "x") can be any Real number.</em></u>
But, when you are dealing with <em>a fraction</em> or <em>even</em><em> square roots</em> you have to be careful because:
You cannot have a ZERO as your <em>denominator </em>and you cannot have NEGATIVE number<em> inside</em> of the square root.
The 2 problems can have infinite solution because it is not a fraction or square root problem and it doesn't break the 2 rules mentioned above.
Answer:
Step-by-step explanation:
Given f(x) = 2x²+16
g(x) = √5x³
First is to get the composite function f(g(x))
f(g(x)) = f(√5x³)
To get f(√5x³), we will replace x in f(x) with √5x³ as shown:
f(√5x³) = 2(√5x³)²+16
f(√5x³) = 2(5x³)+16
f(√5x³) = 10x³+16
Hence f(g(x)) = 10x³+16
f(g(x)) will be the function of amount earned by Raul for the total number hour he works
Answer:
<em>Use </em><em>the </em><em>equation</em><em> </em><em>y=</em><em>mx+</em><em>c</em>
<em>the </em><em>slope(</em><em>m)</em><em> </em><em>is </em><em>2</em><em>,</em><em>y </em><em>is </em><em>-7and </em><em>x </em><em>is </em><em>6</em>
<em>therefore</em><em> </em><em>you </em><em>firstly</em><em> </em><em>have </em><em>to </em><em>find </em><em>the </em><em>y </em><em>intercept</em><em> (</em><em>c)</em>
<em>y=</em><em>mx+</em><em>c</em>
<em>-</em><em>7</em><em>=</em><em>2</em><em>(</em><em>6</em><em>)</em><em>+</em><em>c</em>
<em>-</em><em>7</em><em>=</em><em>1</em><em>2</em><em>+</em><em>c</em>
<em>-</em><em>7</em><em>-</em><em>1</em><em>2</em><em>=</em><em>c</em>
<em>-</em><em>1</em><em>9</em><em>=</em><em>c</em>
<em>then </em><em>replace </em><em>the </em><em>gradient</em><em> </em><em>and </em><em>y </em><em>intercept</em><em> </em><em>in </em><em>the </em><em>equation</em>
<em>y=</em><em>mx+</em><em>c</em>
<em>y=</em><em>2</em><em>x</em><em>-</em><em>1</em><em>9</em>
<em>or </em><em>you </em><em>can </em><em>use </em><em>the </em><em>formula</em><em> </em><em>y-y1=</em><em> </em><em>m(</em><em> </em><em>x-x1)</em>
<em>I </em><em>hope </em><em>this </em><em>helps</em>
30+5x=y
X being the movies watched and y being the initial fee
