Tom jogged 3/5 on Monday and 2/6 mile on Tuesday. How much farther did Tom jog on Monday than on Tuesday
natali 33 [55]
You will want to subtract the amount he ran on Monday from the amount on Tuesday. In order to subtract fractions, we must set them to the same denominator (bottom number). In order to do this, we must multiply 3/5 by 6/6 (the denominator on tuesday) which gets us 18/30. Then, for Tuesday, we must multiply 2/6 by 5/5 (the denominator on Monday) which is 10/30. Now, we can do Monday-Tuesday, 18/30-10/30 which gets us 8/30, if we simplify this, we get 4/15 :)

Mary creates a table of values for a function and plots the points. She finds that the difference in the y values is the same. W
gladu [14]

Answer:

Answer is: A(Linear)

Step-by-step explanation:

A linear function is a function whose graph is a straight line.

It is given that Mary plotted a graph and she found out that the difference in the y values is the same. So such a thing could happen when a function is a linear function.

since, a linear equation is given as:

y=ax+b where a and b are real numbers.

so for distinct values of x say x_{1},x_{2} we get the y-values as y_{1},y_{2}

now,

y_{1}-y_{2}=a(x_{1}-x_{2})

so for equally spaced x_{i}'s we get the difference in y-value to be equal.

Hence, the function is Linear.
