Answer:
x≤−4 or x≥7
Step-by-step explanation:
1)Write the equation again, but replace ___ with x:
(2y + 4b) + 5 = x + (4b + 5)
2) Eliminate parenthesizes (if there is "-" in front of them, change the sign in front of everything that is inside them; if there is "+" just leave it the same):
2y + 4b + 5 = x + 4b + 5
3) Transfer 4b + 5 from the left side to the right by changing signs into the opposite ones:
2y = x + 4b + 5 - 4b - 5
2y = x
So, the answer will be 2y. Hope this helps!
Answer:
680
Step-by-step explanation:
Number of red beans = 30
Number of Blue beans = 30
Number of green beans = 30
How many color combinations of 15 beans have at least 6 green beans?
Since at least 6 of the beans must be green,
Then (15 - 6) = 9
Then, the remaining 9 could be either red, blue or green.
Therefore, C(9 + (9 - 1), 3)
C(17, 3) = 17C3
nCr = n! ÷ (n-r)! r!
17C3 = 17! ÷ (17 - 3)! 3!
17C3 = 17! ÷ 14!3!
17C3 = (17 * 16 * 15) / (3 * 2)
17C3 = 4080 / 6
17C3 = 680 ways

Answer:
The slope of the line in the graph is 1.
Step-by-step explanation:
Slope is determined by rise over run. Meaning that the number of units the slope goes up/down divided by the number of units the slope goes to the left/right is the slope. The rise is one, and the run is one. 1 over 1 equals 1.
