The output of the first one is 21 and you need to find x to the power of 2 subtract 4. So to find where we started add 4 to 21. This gets you to 25 and the square root of 25 is 5. So for the first one X=5

Work showed:

Y=x^2-4
21=x^2-4
Add 4 to both sides
25=x^2
Find the square root of 25 to get X as 5

For the second output (y), plug 21 for x

Y=4x+6
Y=4(21)+6
Y=84+6
Y=90

First part: X=5
Second part: Y=90

wolverine [178]

Answer:

<em>* Siobhan's profit at the grocery store ⇒ $ 10.8 *</em>

Step-by-step explanation:

See below;

Priya's 40% profit in the grocery store ⇒ 40/100 * 9 = 2/5 * 9 = 18/5 ⇒ $ 3.6,

Priya's profit at the grocery store ⇒ 9 + 3.6 ⇒ $ 12.6,

Siobhan's 15% of Priya's profit from the store ⇒ 15/100 * 12.6 = $ 1.8

Siobhan's profit at the grocery store ⇒ 12.6 - 1.8 = $ 10.8

<em>* Siobhan's profit at the grocery store ⇒ $ 10.8 *</em>

8) What is the domain of the function?<br> Please help
alisha [4.7K]

Answer:

{ x | 1, 2, 3, 4, 5, 6, 7, 8, 9 }

Step-by-step explanation:

We note that points between integer values have been excluded, so domain consists of integer x-values from 1 to 9, or

{ x | 1, 2, 3, 4, 5, 6, 7, 8, 9 }

and <em>not</em>

1 <= x <= 9

Which is the difference of 21 1/4 - 18 2/4<br> A 2 1/4 B 2 2/4 C 2 3/4 D 3 1/4
PSYCHO15rus [73]
So when you change the mixed numbers into improper fractions, they become 85/4 and 74/4. Your new problem is 85/4-74/4. Basically 85-74. That equals 9. So the improper fraction answer is 9/4. We now make that back into a mixed number, creating 2 1/4, or A.
