Question 13-18 & 22-27 will all be answered the same way, so i will walk you through question 13: (6,4) y=3x-2

(x,y)=(6,4)

now that we know the first number in the parenthesis is the x value and the second number in the parenthesis is the y value we can plug it into the equation. (x=6,y=4)

4=3x-2 (add two to each side)

4+2=3x

6=3x (divide 3 from each side)

x=2

---------------

y=3(6)-2

y=18-2

y=16

-------------------
answer: (2,16)

now apply the same principles to the other problems!!! hope this helped!!!

What annual rate of interest would you have to earn on an investment of $3500 to ensure receiving $273.00 interest after 1 year?
kogti [31]

To find the answer, we will have to find the percentage of $273 to $ 3500, and we can use the formula:

\frac{interest received}{investment amount} \times 100%

In this case:

273/3500 x 100%

=39/500 x 100%

=7.8%

Therefore the annual interest rate would be 7.8%.

Hope it helps!

Find the distance between the points ( – 9, – 4) and ( – 4,8).
Dmitriy789 [7]

Answer:

Distance=13\ units

Step-by-step explanation:

<u><em>Distance between two points:</em></u> Distance between two pints (x_1,y_1)\ and\ (x_2,y_2) is given by

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Distance between (-9,-4)\ and\ (-4,8).

d=\sqrt{(-4-(-9))^2+(8-(-4))^2}\\\\d=\sqrt{(-4+9)^2+(8+4)^2}\\\\d=\sqrt{(5)^2+(12)^2}=\sqrt{25+144}\\\\d=\sqrt{169}\\\\d=13
