Answer:
y = -1/2x - 1
Step-by-step explanation:
We can use the point-slope form of the equation:
y-y1 = m(x-x1)
Where the given y1 = -2, x1 = 2, and m = -1/2. This yields:
y - (-2) = -1/2(x - 2)
y + 2 = -1/2x + 1
y = -1/2x +1 - 2
y = -1/2x - 1
All the sides add like a rectangle with two sides measuring 4 and two measuring 2 so you would add 4+4+2+2=12
A) x * y = 42 (or x = 42/y)
B) x + y = 23
B) 42/y + y = 23
42 + y^2 = 23y
y^2 -23y + 42 = 0
The numbers are 21 and 2
Hey there! I'm happy to help!
Let's represent the total number of marbles with the variable t. We have the following information.
1/2t+1/6t+8=t (1/2 of total are red, 1/6 of total are blue, 8 are white, add them up to get total)
Now, we solve for t.
1/2t+1/6t+8=t
We combine like terms.
2/3t+8=t
We subtract t from both sides.
-1/3t+8=0
We subtract 8 from both sides.
-1/3t=-8
We divide both sides by -1/3.
t=24
Therefore, there ae 24 total marbles in the bag.
Have a wonderful day! :D
