Mathematics

Answer:

Graph B is a function

Step-by-step explanation:

We can use the vertical line test to determine if a relation is a function.  If a vertical line passes through more than one point, the relation is not a function.

Graph A  At x=-1  a vertical line will pass through 3 points, so it is not a function.

Graph B  A vertical line does not pass through more than 1 point

Graph C  At x=2, it will pass through 2 points so it is not a function

Marizza181 [45]

Answer:

You will save $2 if you buy from Picture Perfect Pizza instead of Pizza Outpost.

Picture Perfect Pizza: $3÷2 = $1.50

Plz help asap !! The high school jazz band is selling homemade leather bracelets at a local craft fair to raise money for a trip
torisob [31]

Answer:

y = 2x - 200

Step-by-step explanation:

The function type that would model this relationship is linear because for each bracelet sold, the jazz band would increase their profit by $2.  Since it has a consistent rate, it is linear.  Using the slope-intercept formula of y = mx + b, where 'm' is the rate and 'b' is the initial value, you can use $2 for the rate or cost per bracelet and -$200 for the initial value or cost of supplies:

y = 2x - 200, where '2' is the cost per bracelet, 'x' the number of bracelets sold, '-200' is the cost for supplies and 'y' is the profit.
