Answer:

  • y = -5x + 7

Step-by-step explanation:

<u>Find the slope:</u>

  • m = (- 8 - 2) / (3 - 1) = -10 / 2 = -5

<u>Use the point (1, 2) and find the equation:</u>

  • y - 2 = -5(x - 1)
  • y = -5x + 5 + 2
  • y = -5x + 7

adell [148]

Answer:

Step-by-step explanation:

Things to remember:

1). When we divide a number having decimal by 10, 100, 1000 or any number multiple of ten, decimal point of the numerator shifts left by the number of zeros present in denominator.

Example:    \frac{2.0}{100}=0.02

2). When we multiply a decimal number by 10, 100, or any number number multiple of 10, decimal point of the original number shifts right by number of zeros present in multiplier.

Example:   2.0 × 100 = 200

In this question, 0.014 × 100000 = 1400.000

Therefore, product of 0.014 and 100000 is 1400 because the decimal point in 0.014 moves 5 places to the right.

If you borrow $900 for 6 years at
attashe74 [19]

Answer:

$1278

Step-by-step explanation:

First you would need to find out how much the annual interest rate is so you would find out what 7% of $900 is which is 63 meaning that there is an annual fee of $63 and since it was for 6 years you would multiply $63 times 6 to get 378 and then to find the total amount you would pay you have to add the interest to what you borrowed so you would do $900 + $378

What are the values of a and b?
ivann1987 [24]

Answer:

<h2>a = 400/21, b = 580/21</h2>

Step-by-step explanation:

Small triangles are similar. Therefore, the sides are proportional

\dfrac{a}{20}=\dfrac{20}{21}               <em>cross multiply</em>

21a=(20)(20)       <em>divide both sides by 21</em>

a=\dfrac{400}{21}

For b, we can use the Pythagorean theorem:

b^2=\left(\dfrac{400}{21}\right)^2+20^2\\\\b^2=\dfrac{160000}{441}+400\\\\b^2=\dfrac{160000}{441}+\dfrac{176400}{441}\\\\b^2=\dfrac{336400}{441}\to b=\sqrt{\dfrac{336400}{441}}\\\\b=\dfrac{\sqrt{336400}}{\sqrt{441}}\\\\b=\dfrac{580}{21}
