Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 4 - x²
g(x) = 2x + 5
<u>Step 2: Find g(-2)</u>
- Substitute in <em>x</em> [Function g(x)]: g(-2) = 2(-2) + 5
- Multiply: g(-2) = -4 + 5
- Add: g(-2) = 1
<u>Step 3: Find f(g(-2))</u>
- Substitute in <em>x</em> [Function f(x)]: f(g(-2)) = 4 - (1)²
- Evaluate exponents: f(g(-2)) = 4 - 1
- Subtract: f(g(-2)) = 3
Answer:
$15 and 50 cents
Step-by-step explanation:
3.25x2=6.50+9=15.50
To get the simplest form of a fraction, simplify or solve it as far as it can be solved. In the case of this fraction for example, both 6 and 18 are divisible by 2. Divisible means both these numbers can be divided by 2.
when we divide them by 2 we get 3 instead of 6 on top and 9 instead of 18 agh the bottom.
6/18 = 3/9
Now 3/9 are both numbers that can further be divided because they can both be divided by 3
this division will give us
1/3 is the answer. This is the simplest form of the fraction 6/18.
