Answer:
Answer to part one of the problem = 24 DVD's
Answer to part two of the problem = 2 · x = y
Answer to part three of the problem = 25 months
Step-by-step explanation:
Part 1:
She buys 2 DVD's a month and there are 12 months in a year.
2 x 12 = 24
The minimum amount of DVD's she buys if she is in the club for one year is 24 DVD's
Part 2:
y = minimum number of DVD's bought after x years
x = amount of months
so the equation would look like this:
2 · x = y
Part 3:
If she sticks to the minimum of buying 2 DVD's a month then we can create this equation:
50 / 2 = 25
she will be a member for 25 months or 2 years and 1 month.
Answer:
488
Step-by-step explanation:
Calculate 20% of their take-home pay
3600 * 0.20 = 720
They already pay 122 and 110 per month
720 - (122 + 110)
720 - 232
488
So the largest monthly car payment they can afford is 488
Step 1: Subtract 13 from both sides.
<span><span><span><span>x^2</span>+<span>6x</span></span>−13</span>=<span>13−13</span></span><span><span><span><span>x^2</span>+<span>6x</span></span>−13</span>=0</span>
Step 2: Use quadratic formula with a=1, b=6, c=-13.
<span>x=<span><span><span>−b</span>±<span>√<span><span>b2</span>−<span><span>4a</span>c</span></span></span></span><span>2a</span></span></span><span>x=<span><span><span>−<span>(6)</span></span>±<span>√<span><span><span>(6)</span>2</span>−<span><span>4<span>(1)</span></span><span>(<span>−13</span>)</span></span></span></span></span><span>2<span>(1)
</span></span></span></span><span>x=<span><span><span>−6</span>±<span>√88</span></span>2
</span></span><span><span>x=<span><span>−3</span>+<span><span><span>√22</span><span> or </span></span>x</span></span></span>=<span><span>−3</span>−<span>√22
</span></span></span>Answer would be
<span><span>x=<span><span>−3</span>+<span><span><span>√22</span><span> or </span></span>x</span></span></span>=<span><span>−3</span>−<span>√<span>22</span></span></span></span>
The answer is b both have 5 on the x
