Estimate 6 8/9 ( 1 9/10 ) by rounding to the nearest whole number. The estimate is the actual product because

13

Step-by-step explanation:

We want to multiply 6 8/9 * 1 9/10. First, we need to transform the mixed numbers into improper fractions:

6 8/9 = (9*6 + 8)/9 = 62/9

1 9/10 = (1*10 + 9)/10 = 19/10

And now we have to multiply each numerator and each denominator, as follows:

62/9 * 19/10 = (62*19)/(9*10) = 1178/90 ≈ 13

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
