21 x 2 = 42
Answer:
![y=\frac{1}{3}x-2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B3%7Dx-2)
Step-by-step explanation:
The equation of a line is given in the form ![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Where
m is the slope with formula ![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
and
b is the y-intercept [y axis cutting point of line]
Given the two points (0, -2) and (6,0),
x_1 = 0
y_1 = -2
x_2 = 6
y_2 = 0
Now, we find m using formula:
![m=\frac{0+2}{6-0}=\frac{1}{3}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B0%2B2%7D%7B6-0%7D%3D%5Cfrac%7B1%7D%7B3%7D)
Now we have
![y=\frac{1}{3}x+b](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B3%7Dx%2Bb)
Finding b, we plug in any (x,y) point. Lets put (6,0) and find b:
![y=\frac{1}{3}x+b\\0=\frac{1}{3}(6)+b\\0=2+b\\b=-2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B3%7Dx%2Bb%5C%5C0%3D%5Cfrac%7B1%7D%7B3%7D%286%29%2Bb%5C%5C0%3D2%2Bb%5C%5Cb%3D-2)
Thus,
equation of line = ![y=\frac{1}{3}x-2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B3%7Dx-2)
Answer:
20 children and 20 adults
Step-by-step explanation:
20 + 20 = 40
Given the chances of getting heads, or getting the answer correct is equivalent to 1/2 or 0.5,
He has a 1/8 chance of answering all the questions correctly.
Answer:
40
Step-by-step explanation:
let the unknown be y (x is used as times(multiplication) )
(y-17)x-6=-138
add /-6 to both sides
y-17x-6/-6=-138/-6
y-17=23
make y independent/add 17 to both sides
y-17+17=23+17
y=40
or in an easier way
-138/-6 =23
23+17=40
simply reversing the question to get the answer
