Tamiku [17]3 years ago

Hey there!

1. How to find f(5)?

  • To find f(5) - simply substitute x = 5 in the function. f(5) means the value of f(x) at x = 5.

2. Substitution and Evaluate

\large{f(5) =  - 4( {5})^{2}  + 6(5) - 4}

Remember to follow the PEMDAS/BODMAS rules! Exponent comes before multiplication.

\large{f(5) =  - 4(25) + 30 - 4} \\  \large{f(5) =  - 100 + 30 - 4} \\  \large{f(5) =  - 74}

3. Final Answer

  • f(5) = -74

Mia and Luke made 85 origami together. Mia made 4 pieces of origami every 3 minutes. Luke made 3 pieces of origami every 4 minut
julia-pushkina [17]
For ease of solving, let's first find the rate of Mia and Luke per minute. Since Mia can do 4 pieces every 3 minutes, then she can do \frac{4}{3} of a piece per minute. Luke on the other hand can do \frac{3}{4} of a piece per minute.

To find how many pieces they made, we first need to find the time it took for them to make the pieces. We assign t as the time Mia spent making origami. Since Luke spent 5 more minutes, we can denote his time as t+5.

Putting this into an equation we'll get:
\frac{4}{3}t+ \frac{3}{4}(t+5)=85
\frac{4}{3}t+ \frac{3}{4}t+\frac{15}{4}=85
\frac{25}{12}t=81.25
t=39

Therefore, Mia made pieces of origami for 39 minutes. Knowing this, we can find out the number of pieces of origami she made:
39* \frac{4}{3} =52

ANSWER: Mia made 52 pieces of origami.
