Jacob buys four muffins for $5.00. what is the cost of 7 muffins? enter your answer in the box.

cost of 7 muffins is $8.75

Step-by-step explanation:

Unit rate defined as the rates are expressed as the quantity 1 such as 2 miles per hour or 4 meter per seconds.

As per the given statement:

Jacob buys four muffins for $5.00.

then;

Substitute the given values we have;

We have to find the cost of 7 muffins:

By definition of unit rate;

Substitute the given values we have;

Therefore, cost of 7 muffins is $8.75

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
