Answer:
Well I believe that this is not a proportional relationship. Why? Well because in order for it to be a proportional relationship it has to go through the origin. This equation would go through (30,0) instead of (0,0) therefore it is not a proportional relationship.
Step-by-step explanation:
Answer:
w = 2 He bought 2 packages of white socks
Step-by-step explanation:
6(8) + 4w = 56
48 + 4w = 56
4w = 8
w = 2
Check your work
6(8) + 4(2) = 56
48 + 8 = 56
56 = 56
Blank 1: If y is -5 when x is 2, that means the equation here is y = -2.5x. So, if x is 8, that makes the equation y = -2.5(8), which gives you -20.
Blank 2: If y is 3 when x is 1, the equation will be y = 3x. If x is 2, that will give you y = 3(2), which is 6.
Blank 3: If y is -7 when x is -21, the equation will be x = 3y. If y is 9, that will give you x = 3(9), which is 27.
Blank 4: If y is 5 when x is 4, the equation will be y = 1.25x. If y is 18, that makes the equation 18 = 1.25x, which is 14.4.
I hope this all helped!
A large MAD (mean absolute deviation) tells us that there is a lot of variation in the ages of the swimmers. It tells us specifically that there are a lot of swimmers that are not close the to the age of 10 (which is the mean).
Answer:
(x + 5)
Step-by-step explanation:
(x² - 25) ÷ (x-5)
=(x² - 5²) ÷ (x-5)
Using the formula a² - b² = (a + b)(a - b) you get
= (x + 5)(x - 5) ÷ (x - 5)
With division you can cut both (x - 5)
So the answer is (x + 5)
