Answer:
16
Step-by-step explanation:
Subtracting the given expressions, that is
3b² - 8 - (b(b² + b - 7) ) ← simplify parenthesis
= 3b² - 8 - (b³ + b² - 7b) ← distribute parenthesis by - 1
= 3b² - 8 - b³ - b² + 7b ← collect like terms
= - b³ + 2b² + 7b - 8 ← substitute b = - 3
= - (- 3)³ + 2(- 3)² + 7(- 3) - 8
= - (- 27) + 2(9) - 21 - 8
= 27 + 18 - 21 - 8
= 16
Answer: 12s+27j≤450
Step-by-step explanation:
From the question, we are informed that Jackie has a maximum of $450 to spend on shirts and jeans and that the shirts she wants to buy are $12 each, including tax while the jeans she wants to buy are $27 each, including tax.
The inequality that represents all possible combinations of s, the number of shirts, and j, pairs of jeans, Jackie can buy will be:
= 12s+27j≤450
Answer:
D
Step-by-step explanation:
First put the data from smallest to largest
12 points, 17 points,21 points, 23 points, 24 points, 28 points,29 points
The left end of the whisker should be 12 (This eliminates graph a)
The right end of the whisker should be 29 (This eliminates graph b)
There are 7 points
The middle point is 4
The 4th point is 23
That is the line in the middle of the box (This eliminates graph c)
The lower line of the box is at at point 2 = 17
The upper line of the box is at point 6 = 28
This leaves us with graph D
The answer is the square root of 23 i.
(The “i” is outside of the square root symbol, and the 23 is positive).
Hope this helps! (:
