Which expression has an estimated product of 45? 44.7 times 2.1 7.5 times 8.4 8.7 times 5.28 38.1 times 7.3

C) 8.7 x 5.28

Step-by-step explanation:

Round 8.7 to 9, and round 5.28 to 5. Then you know your answer is reasonable because when you multiply 5 x 9, it equals 45! Hope this helps...

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
