General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Algebra I

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

x - 4y = 12

x - 5y = 15

Step 2: Solve for y

Elimination

Subtract 2 equations: y = -3

Step 3: Solve for x

Define original equation: x - 4y = 12
Substitute in y: x - 4(-3) = 12
Multiply: x + 12 = 12
Subtract 12 on both sides: x = 0

Jojo likes to paint. She estimates the number of paintings she completes using the function P of w equals two thirds times w min

pantera1 [17]

Answer:

$P = \frac{2}{3} [J(y)] - 2$

Step-by-step explanation:

If Jojo completes P number of paintings working w weeks then the relation between P and w is given by $P = \frac{2}{3} w - 2$ . ........ (1)

Again, the function J(y) represents how many weeks per year she spends painting.

So, w = J(y). ...... (2)

Therefore, the composite function which represent how many paintings Jojo completes in a year, is given by

$P = \frac{2}{3} [J(y)] - 2$ (Answer)
