For 11, we can subtract x from both sides for the first equation to get y=8-x, making the slope -1 for both equations and therefore making it parallel.
For 13, we can solve for y in the first equation by subtracting 14 from both sides and therefore getting 2x-14=y. For the next one, we can subtract 4x from both sides to get 10-4x=2y. Dividing both sides by 2, we get 10-2x=y. Since for the equations to be parallel they must be the same and for perpendicular they must be -1/(slope), this fits neither.
Using those two explanations, I implore you to solve the other two on your own!
Hello!
Really, we could finish this problem without knowing the slope or just having one of the given points.
However, since they gave us the slope, let's take the easier way.
y = 2x + b
To find b, we can plug in one of the points. (it doesn't matter which)
7 = 2(5) + b
7 = 10 + b
b = 7-10 = -3
So, the final equation is y = 2x - 3 or answer choice D.
Hope this helps!! let me know if you have ANY questions.
Answer:
Skewed left
Step-by-step explanation:
The graph is skewed left because there are many points on the left side of the graph, but only a few on the right side.
Hope this helps!
Subtract 249 from 417 and you’ll get 168 then divide 168 by 2 and you’ll then get 84
So train b is 84 tons
Train A is 249+84 so 333
First, you divide the price by the amount of units in the pack. This is how you find how much one unit is worth in that pack. So for the first pack you divide 1.12 by three, and then you have .37333 repeating, which is about 38 cents. Next is the second pack, where we divide 4.38 by 12 which is .365, which is about 37 cents. The last pack is 8.68 divided by 24 which is .361, or about 36 cents. This means that the 24 pack is the best buy.
In real life you should also consider which would be too much for you or not enough. For example, you might not even need 24 units of juice. You might only need 12 so you don't have too much extra. But hey, this is just a math problem ;)
