Answer:
y = -2/5x -6
slope is -2/5
y intercept -6
Step-by-step explanation:
8x+20y=-120
Slope intercept form is y = mx+b where m is the slope and b is the y intercept
Subtract 8x from each side
8x -8x+20y= -8x-120
20y = -8x - 120
Divide by 20
20y/20 = -8x/20 -120/20
y = -2/5x -6
For this case we must express the number "423" in a radical way.
We have to, we can rewrite it as:

So, we have to:

By definition of properties of powers and roots we have:
![\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D)
So:

Answer:

You would have to put them into different shapes and the formula for the squares is sides^2 and the formula for the triangles is 1/2(b*h), eventually you will add the numbers together
Answer:
4
Step-by-step explanation:
The three angles in a triangle measure 180°. So add the the 2 known angles 70° + 63° = 133. Then subtract it from 180° to get the unknown angle 180 - 133 = 47.
Now that we know the third angle is 47 we find which number that when multiplied by 11 and 3 is added to that number you get 47.
11×4+3 = 47
Therefore l, the answer is 4
Answer:
r=11
Step-by-step explanation:
First thing you should do is add 24 to both sides. This is
-24+3r+24=9+24
Then you would get:
3r=33
Next you would do
33/3
To find:
r=11
