Answer:

7. x = 4

8. x = 10

Step-by-step explanation:

7. The angles are equal to each other so you can do

40 = 12x - 8

48 = 12x

4 = x

8. The angles add up to be 180 degrees so you can combine them and set them equal to 180

6x + 12x = 180

18x = 180

x = 10

I need to complete the equation of the line through (3 -1) and (4 7). I am really stumped on this topic, please explain the proc
Nana76 [90]

Assuming you want the equation in slope intercept form, you first need to use slope formula to find the slope.

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Plug in the coordinates that you have, (3,-1) and (4,7), for the x and y values respectively.

\frac{-1-7}{3-4}

Which reduces to 8/1=8.

The slope of your equation is 8.

Slope intercept form is: y=mx+b. m is your slope and b is your y-intercept, x and y stay unchanged.

Plug the slope in:

y=8x+b.

Now, you can plug one of the sets of coordinates into the x and y of the equation to find b. I'm using (3,-1).

-1=8(3)+b

-1=24+b

Subtract 24 from both sides.

-25=b

Now plug this into the equation!

y=8x-25 is your final equation.

I hope this helps :)

Q2) for both of the following, calculate A5 and A100.<br> (i) An= 6n-3
dlinn [17]

Answer:

27 and 597

Step-by-step explanation:

To evaluate A5 and A100, substitute n = 5, n = 100 into An , that is

A5 = 6(5) - 3 = 30 - 3 = 27

A100 = 6(100) - 3 = 600 - 3 = 597
