\huge\text{Hey there!}

\textsf{(9 - r)(2 - 3r)}

\textsf{= 9(2) + 9(-3r) + 2(-r) + (-r)(-3r)}

\mathsf{= 18 - 27r - 2r + 3r^2}

\mathsf{= 3r^2 + 18 - 27r - 2r}

\boxed{\large\text{COMBINE the LIKE TERMS}}

\mathsf{= 3r^2 + 18 + (-27r - 2r)}

\mathsf{= 3r^2 + 18 - 29r}

\mathsf{= 3r^2 - 29r + 18}

\boxed{\large\textsf{Therefore, your answer is: \large\boxed{\mathsf{3r^2 - 29r + 18}}}}\large\checkmark

\huge\text{Good luck on your assignment \& enjoy your day!}

Answer:

Mean- 14.5

Median- 15.5

Interquartile Range- 7.5

Step-by-step explanation:

The mean is a type of average. It is the sum (total) of all the values in a set of data.

The median is the middle number in a sorted, ascending or descending, list of numbers.

The interquartile range describes the middle 50% of values when ordered from lowest to highest.

there are 20 guests at a party the host has 8 gallons of punch he estimates that each guess within 2 cups of punch if his estima
AlekseyPX
STEP 1:
convert gallons to cups & calculate total number of cups

1 gallon= 16 cups

= 8 gallons * 16 cups/gallon
= 128 cups total


STEP 2:
calculate total cups estimated for 20 guests

= 20 guests * 2 cups/guest
= 40 cups needed for guests


STEP 3:
subtract the difference between step 1 and step 2 to find leftover punch

= 128 cups - 40 cups
= 88 cups leftover

OR

GALLONS LEFTOVER
= 88 ÷ 16 cups/gallon= 5 1/2 gallons


ANSWER: There will be 88 cups or 5 1/2 gallons of punch leftover.

Hope this helps! :)

I’ve been stumped on this question for a while (picture included)
julsineya [31]

Answer:

Since the question is indicating to use a graphing calculator, we can assume that we would be required to graph both of the equations.

Red = \sqrt{x+2}

Blue = 3x^2-4x-1

By graphing those equations, we can determine the solution(s)

The points where the graphs intersect would be your coordinates to derive your solution

Red = (1.864, 1.966)

Blue = (-0.427, 1.254)

The solutions would be the x-value of the ordered pair, in this case,

x = 1.864 AND x = -0.427

= 21x - 1

Step-by-step explanation:

= (4x + 12x) + (5x - 1)

= 4x + 12x + 5x - 1

= 16x + 5x - 1
