First, subtract 2x from both sides of the equation to get 8y = -2x - 32. Then, divide the equation by 8, to get y = -x/4 - 4. Your y-intercept will be -4, and it's slope will be -1/4.

3 + 5 +7 +9 + 11 + ....

n = 100

a = 3

d = 5 - 3 = 2

S_{n}=\frac{n}{2}(2a + (n-1)d)\\\\S_{100}=\frac{100}{2}(2*3+99*2)\\\\=50*(6+198)\\\\= 50 * 204\\= 10200\\

Bo has $500 in his savings account. He plans to add $150 to his savings account every month. Recently, he purchased a tractor to
MariettaO [177]

Answer:

A. $2,000

Step-by-step explanation:

<em>Assuming that the money in the savings account will be used to pay off for tractor.</em>

<em>let the number of months be m</em>

Savings after m months will be 500+ 150m

After m months the installments paid  will 200m

To find the months it will take to pay for the tractor in m months, savings and the installments will be the price of the tractor. As an equation it be represented as below:

500+150m +200m = 4000

150m + 200m = 4000-500  <em>(grouping like terms)</em>

350m = 3500  <em>(Making m the subject of the formula)</em>

350m/350  = 3500/350

m = 10

Substituting m into the equation of saving after m months

<em>Savings after m months will be</em> 500+ 150m

<em>Savings after m months will be</em> 500 + 150(10)

<em>Savings after m months will be</em> 500 + 1500

Savings after m months will be $2000
