F(x)=a(x-h)^2 + k
f(x)=a(x + 2)^2 - 9
f(0)=5
5=a(0+2)^2 - 9
5=4a-9
4a=14
a= 7/2
f(x)=7/2(x^2 + 4x + 4)-9
=7/2x^2 +14x + 14 - 9
f(x)=3.5x^2 +14x + 5

VMariaS [17]

Using proportions, it is found that his DAILY RATE on that particular day is of Php 2,420 .

This question is solved by proportions, using a <em>rule of three.</em>

In a regular 8-hour day, Allen earns Php 1420. How much will he earn on a 14 hour day?

The <em>rule of three</em> is:

8 hours - Php 1420

14 hours - x

Applying cross multiplication:

$8x = 1420 \times 14$

$x = \frac{1420 \times 14}{8}$

$x = 2485$

The closest option is Php 2,420.

Solve the literal equation for the indicated variable. Show your work.<br><br> P=2(l+w) for l.

Norma-Jean [14]

Answer:

l = P/2 -w

Step-by-step explanation:

P=2(l+w)

Divide each side by 2

P/2 = 2(l+w)/2

P/2 = l+w

Subtract w from each side

P/2 -w = l+w-w

P/2 -w =l
