Answers

Answer 1

Answer:

Answer:

-213

not in d option though check d question

Step-by-step explanation:

h(r) = 23r − 6

h(-9) = 23(-9) - 6

= -207 - 6

= -213

Answer 2

Answer:

Answer:

-213

Step-by-step explanation:

If h(r) = 23r − 6, then, if we choose r = 2 as an example (only), then:

If h(2) = 23(2) − 6 = 46 - 6 = 40

Using the same approach, we substitute -9 for r, obtaining:

If h(-9) = 23(-9) − 6 = -207 - 6 = -213

Answers

so we can get pairs
(x,y)
we have
(-3,-3)
(7,-3)
(7,2)

so list known ones
x=-3,7,7
y=-3,-3,2
we find pairs
x=7 and 7
y=-3 and -3
the missing one is another -3 for x and 2 for y
therefor the last point is
(-3,2)

he is wrong, its 30. not 300 thousandths

He is incorrect because .3 ( three tenths ) x 100 = 30, not 300, because .3 is a decimal. If it was 3 x 100, he would have been correct. BRYARTOWNSEND is correct.

Hope this helped!!
