The manager of a mail order business will ship the packages to their customers. The cost, in dollars, to mail a package is based
Nadya [2.5K]
To determine the cost of the mail, we simply substitute the mass of the package to the given function. Mathematical functions are used to relate two variables, observing how changing one variable affects the other variable. For this case, the cost of a mail and the weight of the package are related by the function <span>y = 0.7x2 –2.5x + 3 where x represents the mass in units of pounds (lb) and y is the cost in units of dollars ($). We calculate cost as follows:

</span><span>y = 0.7x^2 –2.5x + 3
</span><span>y = 0.7(5)^2 –2.5(5)+ 3
y = 8 dollars

Therefore, the cost of mailing a 5 lb package would be 8 dollars.

Angles X and Y are supplementary. Angle X is 3 times the measure of angle Y. What is the measure of angle X?
never [62]

Answer:

∠ Y = 45°, ∠ X = 135°

Step-by-step explanation:

Since the 2 angles are supplementary, then

X + Y = 180 ← substitute X = 3Y

3Y + Y = 180, that is

4Y = 180 ( divide both sides by 4 )

Y = 45

and

X + Y = 180, so

X + 45 = 180 ( subtract 45 from both sides )

X = 135

Thus

∠ X = 135° and ∠ Y = 45°
