Rewrite the equation 2x+8y=16 in slope-intercept form

Shkiper50 [21]

The goal is to solve for y. Start by subtracting 2x from both sides. This gives you 8y=-2x+16. Now just divide both sides by 8, which gives you y=-2/8x+16/8. Finally, simplify this to y=-1/4x+2.

Can anyone help me on this question please.

The answer is 72.
You can figure this out using the Pythagorean theorem: C (78) squared - A (30) squared = B squared though since you already know the longest side.
78 x 78 = 6084
30 x 30 = 900
6084-900= 5184
The square root of 5184 is 72.

Create a BOX PLOT with this data set by using the Jamboard attached to this assignment... 3, 1, 3, 7, 5, 2, 3, 6, 3

navik [9.2K]

Answer:

Step-by-step explanation:

in order to make a box plot you need to know 5 things.

the minimum, the first quartile, the median, the third quartile, and the maximum value. aka the five number summary

using your calculator you can find that in this set of values:

min = 1

Q1 = 2.5

med (Q2) = 3

Q3 = 5.5

max = 7

the box plot will look something like this:
