Jacob and mark started taking a test at the same time. jacob finished his test 10 minutes before mark. which equation represents the time, j, jacob spent on the test compared to the time, m, mark spent on the test?

j=m-10

Step-by-step explanation:

If j respresentst he time Jacob spent in the test and m the time Mark spent on the test. We can write an expression that shows the amount of Time Jacob spent on the test compare to Jacob:

We know that Jacob finished the test 10 minutes before Mark.

Let j equal the Total time Jacob spent in terms of Marks time is:

Jacob spends m-10 on the test compared to Mark

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
