The domain of this function is {-12, -6, 3, 15}. y=-2/3x+7 complete the table based on the given domain.

Nookie1986 [14]

If the domain of the function y=-2/3 x+7 is {-12,-6,3,15} then the range of the function is {15,11,5,-3}.

Given that the domain of the sunction y=-2/3 x+7 is {-12,-6,3,15}.

We have to find the range of the function and complete the table.

Function is relationship between two or more variables expressed in equalto form. In a function each value of x has some value of y.

To complete the table we need to find the value of the function at different values of x.Domain is basically value of x which satisfies the function.

We have to first put the value of x=-12 in y=-2/3+7

y--2/3*-12+7

=15

Now put x=-6 in the function.

y=-2/3 *-6+7

=3

Put the value of x=3 in the function.

y=-2/3*3+7

=5

Put the value of x=15.

y=-2/3*15+7

=-41/3.

Hence the range of function is {15,11,-41/2,5}.

An English instructor asserted that students' test grades are directly proportional to the amount of time spent studying. Lisa

hodyreva [135]

Answer:

Lisa has to study for 7.55 hours.

Step-by-step explanation:

Since an English instructor has asserted that the relation between studies and test grades is proportional then we can find the time by unitary method.

∵ To score 77 Lisa has to study for 6 hours.

∴ To score 1 Lisa has to study for = $\frac{6}{77}$

∴ For a score of 97 Lisa has to study = $\frac{6}{77}(97)$

= 7.55 hours

So Lisa has to study 7.55 hours to score 97 in the test.
