Pythagorean Theorem: a^2 + b^2=c^2....13^2 + 7^2 = x^2...169+49=x^2...218=x^2... √218= 14.8 . So the answer is 14.8

How do you write the equation of a line (in slope intercept form) with three given points?​
Mrrafil [7]

With even just two points, you can find the equation of a line in slope-intercept form.

Slope-intercept form: y=mx+b where m is the slope and b is the y-intercept

<u>1) Solve for the slope (</u>m<u>)</u>

The equation to solve for the slope is m=\frac{y_2-y_1}{x_2-x_1} when the two points are (x_1,y_1) and (x_2,y_2). Plug the coordinates of these points into the equation and solve for m.

Then, plug m into y=mx+b.

<u>1) Solve for the y-intercept (</u>b<u>)</u>

Then, take any of the given points and plug it into y=mx+b along with the slope. Isolate b to get the y-intercept. Then, plug both m and b back into y=mx+b to get your final equation.

I hope this helps!

deenas water bottle can hold a total of 2/5 liter of water. johns water bottle can hold a total of 5/2 liter of water whose wate
Alexandra [31]
John's. Find the first common multiple of both denominators, in this case it's going to be ten, then the number you had to multiply to change these numbers to the common multiply you do to the numerators. so it works out like so:

Deena has a bottle of 4/10
John has a bottle of 25/10 or 2 1/2 (simplified)

If x varies directly with y and x=6 when y=8, find x when y=18.
andrey2020 [161]

Answer:

x = 13.5

Step-by-step explanation:

direct variation

y = kx

substitute x and y to find k

8 = k*6

divide by 6

8/6 =k

4/3 = k

y = 4/3 x

now put in y =18

18 = 4/3 x

 multiply by 3/4

18 * 3/4 = 3/4 * 4/3 x

54/4 = x

change to a decimal

13.5 =x
