Answer:
f(-3) = 21
Step-by-step explanation:
To solve this, you can replace all x's with -3 and then solve to find the answer.
f(x) = x^2 - 4x
f(-3) = -3^2 - 4(-3)
f(-3) = 9 - (-12)
f(-3) = 21
I hope this helps!
Using proportions, the amounts received by each student are given as follows:
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The amounts that each receive are given as follows:
- Ahmed: 6/7 of Ali, hence 6x/7.
- Amir: 1/7 of Ali, hence x/7.
The total amount shared is of Rs 1,400,000, hence we can solve for x as follows:
x + 6x/7 + x/7 = 1,400,000.
2x = 1,400,000.
x = 700,000.
Hence the amounts are:

That means multiplying the two fractions, but to do so, lets first convert the whole part to fraction as well, and remember that to multiply fractions you multiply numerator times numerator and denominator times denominator as well:
1 3/4 = 1 + 3/4 = 4/4 + 3/4 = 7/4
150 1/2 = 150 + 1/2 = 300/2 + 1/2 = 301/2
therefore:
<span>1 3/4 of 150 1/2
</span><span>= (1 3/4)(150 1/2)
= (7/4)(301/2)
= (7*301)/(4*2)
= 2107/8
that is the result</span>
