<u><em>When x = -2</em></u>, f(x) = -7(-2) + 3 = 14 + 3
<u><em>x = 17</em></u>
<u><em>When x = 5</em></u>, f(x) = -7(5) + 3 = -35 + 3
<u><em>x = -32</em></u>
All you have to do to solve the function is substitute the value of x into the equation.
Answer: 3/4 hour
Step-by-step explanation: Add them all to get 3 3/4. subtract that from 4 1/2.
Answer:

<h3><u>x>55.25</u> is the right answer.</h3>
Answer:

Step-by-step explanation:
- The lengths of the sides of a 30-60-90 triangle are in the ratio 1:2:√3.
- The lengths of the sides of a 45-45-90 triangle are in the ratio 1 : 1 : √2
- We can get the length of the longest side of the bottom triangle is 9×2÷√3 =

- And based on the theory shown on the 2nd step, we can get x (the length of the longest side of the upper triangle) is
x√2
