y varies directly with x, then y = kx

y is 2.5 when x is 5, k = y/x = 2.5/5 = 0.5

The equation is y = 0.5x

when x = 10,

y = 0.5(10) = 5

y is 2.5 when x is 5, k = y/x = 2.5/5 = 0.5

The equation is y = 0.5x

when x = 10,

y = 0.5(10) = 5

If the graph of y = |x| is translated so that the point (1, 1) is moved to (4, 1), what is the equation of the new graph?
y = |x - 3|
y = |x| - 3
y = |x + 3|
y = |x| + 3 **Weegy:** B. y = |x| - 3 (More)

Adrenaline is released by the _____.
hypothalamus
adrenal glands
pituitary gland
parathyroid glands **Weegy:** The primary function of the pituitary gland is to secrete and store the chemical messages known as hormones and to regulate other glands within the body?s endocrine system. [ The pituitary is often referred to as the ?master gland? because of its influence on other hormone-secreting glands of the endocrine system. There are three lobes in the pituitary gland ? the anterior, intermediate and posterior lobes ? and they each control types of hormones. ] (More)
