Step-by-step explanation:
Say you have these 2 fractions

Cross multiply as following;

If in the end, both numerator and denominator are equal, then the fractions are equivalent.
Examples:
Example 1

Cross multiply

They're equivalent.
Example 2

Cross multiply

They're not equivalent.
So it’ll be 42 divided by 6 since u want to know how many servings of 6 ounces can be served from a 42 pound bag

Answer:
B.
Step-by-step explanation:
Let x be number of days and y be value of card.
It has been given that your parents gave you a gift card for your favorite coffee shop. The card was worth $50 when you got it. Each day, you buy a drink for $3.
We can see that value of card is dependent on number of days as value of card decrease by 3 each day. This means that slope of our line will be -3.
As initially you have $50, this means that y-intercept of our given line will be 50.
Since we know that equation of a line in slope-intercept form is:
, where,
m = Slope of line.
b = y-intercept.
Upon substituting our given values in slope intercept form of equation we will get,

Therefore, the equation
shows the value on the gift card over time.

Step-by-step explanation:
The vertex is either the highest point on the parabola or the lowest point. We have a positive parabola, so the vertex is a low point. It sits at (2, -4). Locate that point and see what I mean by the lowest point on the parabola.
