Han buys candy at $3.75 a pound. What equation best
represents his total cost (y), if x is the number of pounds
of candy he purchased?
a) x = y + 3.75
b) X = 3.75y
c) y = x + 3.75
d) y = 3.75 x

D) y= 3.75x

Step-by-step explanation:

The total cost is y, therefore you set the equation equal to y since you want to find the total cost of candy he purchased.

X is the number of pounds, and the candy is $3.75 each pound.

When you set up the equation, it is

y=3.75x

Which also means: the total cost of the candy depends on how many pounds (which is $3.75 per pound) he buys.

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
