Answer:
y = -5x + 3
Step-by-step explanation:
Using slope intercept form
y = mx + b
You need to use Sin to find the length of BC and the answer is 8.
<h3>
===> Exercise 1</h3>
(3x² - 7x + 14) + (5x² + 4x - 6)
Match 3x² and 5x² to get 8x².
Combine −7x and 4x to get −3x.
Subtract 6 from 14 to get 8.
Therefore, the expression (3x² - 7x + 14) + (5x² + 4x - 6), is equivalent to the expression "B".
<h3>
===> Exercise 2</h3>
(2x² - 5x -3) + (-10x² + 2x + 7)
Combine 2x² and -10x² to get −8x².
Combine −5x and 2x to get −3x.
Add −3 and 7 to get 4.
Therefore, the expression (2x² - 5x -3) + (-10x² + 2x + 7), is equivalent to the expression "A".
<h3>
===> Exercise 3</h3>
(12x² - 2x - 13) + (-4x² + 5x +9)
Combine 12x² and -4x² to get 8x².
Combine −2x and 5x to get 3x.
Add −13 and 9 to get −4.
Therefore, the expression (12x² - 2x - 13) + (-4x² + 5x +9), is equivalent to the expression "C".
The television set would have cost Mr. Brown a total of $960, or answer D. How I determined this answer:
So, you already know the amount of the first installment: $110. Each installment increases by $20, so for the next installment (a.k.a the 2nd installment), Mr. Brown would have to pay $130. Basically, you have to add $20 more to each previous amount. Here are all of the installment prices:
Installment 1: $110 + $20 =
Installment 2: $130. Add $20 and you get -
Installment 3: $150 + $20 =
Installment 4: $170 + $20 =
Installment 5: $190 + $20 =
Installment 6: $210.
Now that you have all of the total amounts Mr. Brown had to pay for each installment, your final step is to add all of those amounts together in order to determine your answer. How you do this:
$110 + $130 + $150 + $170 + $190 + $210 = $960, or D.
And that is how you get the answer. I hope I was able to help you! :)
3/6. If you have the same Numerator (in this case 3), the choice with the smaller denominator (6 or 8) is the larger of the numbers
