Complete each order pair so that it is a solution of the given linear equation.

PtichkaEL [24]

Each ordered pair is (x,y). Determine the coordinates by substitution.

for (15,y):
y=1/3 * 15 - 9
y=-4

for (x,-6):
-6=1/3x -9
1/3x=3
x=9

Prove algebraically that (m + 2)2 – m 2 – 12 is always a multiple of 4

Julli [10]

Answer:

$(m + 2)^{2} - m^{2} - 12 = 4(m - 2)$

Step-by-step explanation:

Step 1:

Write the expression

$(m+2)^{2} - m^{2} - 12$

Step 2: Expand $(m + 2)^{2}$

$(m+2)^{2} - m^{2} - 12\\(m+2)(m+2) - m^{2} - 12\\m^{2} + 2m + 2m + 4 - m^{2} - 12$

Step 3: Collect similar terms

$m^{2} - m^{2} + 4m + 4 - 12\\4m - 8$

Step 4: Factor 4 out of the expression to prove that the expression is a multiple of 4.

$Therefore\\4m - 8 = 4(m - 2)\\Hence,\\(m+2)^{2} - m^{2} - 12 is a multiply of 4 because the expression is equal to 4(m-2)$

You are paid $82.50 for 7 1/2 hours of work, whats is your rate of pay?

ra1l [238]

Answer:

Rate of Pay is $11 per hour.

Step-by-step explanation:

Cost of $7\frac{1}{2}\:hr$ of work = $ 82.50

To find: Rate of pay

Here Rate of Pay means Cost of 1 hour of work or we can say cost of per hour work.

$7\frac{1}{2}=\frac{7\times2+1}{2}=\frac{15}{2}$

⇒ Cost of $\frac{15}{2}\;hr$ of work = $ 82.50

Cost of 1 hr of work = $\frac{82.50}{\frac{15}{2}}$

= $\frac{82.50\times2}{15}$

= $\frac{165}{15}$

= $ 11

Therefore, Rate of Pay is $11 per hour.

A television and DVD player cost a total of $1230. The cost of the television is two times the cost of the DVD player. Find the

nikitadnepr [17]

Answer:

Television = 820

DVD Player = 410

Step-by-step explanation: Imagine the television as 2, and the DVD player as 1. If you’re were to draw it out with boxes, you’d see that the tv has two boxes and the DVD player has 1 box. All are exactly the same amount, and there are a total of three boxes. So divided 1230 by 3 and you get 410. Using the idea of the boxes, the DVD player get’s one 410, and the tv gets two 410s, or 820.
