What is 5m2- 15m- 200
vitfil [10]

Answer:

5(m + 5) (m - 8)

Step-by-step explanation:

5m2- 15m- 200

Start by pulling 5 out.

5(m^2 - 3m - 40)

We consider all factors of 40  

1    40

2   20

4    10

5     8

Based on the middle term we know that 5   and 8 are our best option.

5(m     5) (m     8)

We know the signs have to be one + and one -  because a - * - = + and + * + = +

Since 5 - 8 would give us -3 we know that our answer is

5(m + 5) (m - 8)

Ieda and Thanh both offer piano lessons. Ieda charges an initial fee of $8.50 and an hourly rate of $11.00. Thanh charges an ini
Verizon [17]

Answer:

after 3 hours of instruction.

Step-by-step explanation:

First, start by setting up the equation.

Leda charges an initial fee, meaning this fee is only going to be one time. However, there is an hourly rate of 11. Since we do not know how many hours these piano lessons are going to last, we put a variable (I will use x), after this number.

The initial fee is 8.50. There needs to be a variable after 11 because that is the number we don't know.

The equation for Leda's lessons are <em>8.50+11.00x. </em>

Now, we need to find out what the equation for Thanh's lessons are going to be, because we're going to be setting both equations equal to each other to find out when they cost the same. At the moment both equal each other, is when they are the same amount.

Thanh's equation also has an intial fee and an hourly rate. So, the equation will be

<em>10.00+10.50x. </em>

Now we solve.

<em>8.50+11.00x = 10.00+10.50x </em>

First, subtract from both sides. We will do the numbers without variables first.

<em>8.50+11.00x = 10.00+10.50x </em>

<em>-8.50               -8.50 </em>

<em>____________________</em>

<em>0     +11.00x =   1.50 +10.50x</em>

Then, subtract the x's. (taking away the zero because it is equivalent to nothing)

<em>11.00x =   1.50 +10.50x</em>

<em>- 10.50x            -10.50x</em>

<em>__________________</em>

<em>0.50x = 1.50 </em>

Lastly, to find out the answer, we divide.

1.50/0.50= 3.

<u>To check your answer, you can plug into the original equation. </u>

<em>8.50+11.00 times 3 = 10.00+10.50 times 3 </em>

Both sides equal 41.50, meaning they are equal to each other!
