The answer to your question would be D.

D. Range: 20

Mean: 10

Median: 9

Mode: none

Step-by-step explanation:

1, 2, 3, 8, 9, 12, 14, 20, 21

Range: 21 - 1 = 20

Mean: 1 + 2 + 3 + 8 + 9 + 12 + 14 + 20 + 21 = 90/9 = 10

The function is defined by f(x)= x^2+3x-10

yaroslaw [1]

First you put (x+5) into the initial function wherever you see x so it becomes
(x+5)^2+3(x+5)-10=x^2+kx+30
(x^2+5x+25)+(3x+15)-10 simplified left side
x^2+8x+30 fully simplified left side
thus k=8
x^2+8x+30=0 to find 0s
-4 + 3.7416573867739i
-4 - 3.7416573867739i
these are the roots you find after using the quadratic formula
the second one is the smallest

Anna is selling boxes of chocolate chip cookies (c) for $6 each and boxes of peanut butter cookies (b) for $7 each. She must

Georgia [21]

Answer:

$x+y\geq30$

$6c+7b\geq175$

Step-by-step explanation:

Given : Let c represents the number of boxes of chocolate chip cookies and b represents the boxes for butter cookies.

Anna is selling boxes of chocolate chip cookies (c) for $6 each and boxes of peanut butter cookies (b) for $7 each.

i.e. Cost of 'c' chocolate chip cookies = 6c

Cost of b butter cookies = 7b

She must sell at least 30 boxes of cookies and at least $175 worth of cookies.

i.e. $x+y\geq30$

$6c+7b\geq175$

Thus , the system of inequalities models this situation :

$x+y\geq30$

$6c+7b\geq175$

I don't understand (t+8)(-2)=12

Evgen [1.6K]

It it called an equation. Equation consist of number, symbols, and a equal sign.
To solve, first do -2 times t and -2 times 8. Your equation would look like this after: -2T+(-16)=12. Then add 16 to each side. -2T=28. Next, divide by -2. T=-14 is your answer.
