Answer:
Used a calculator to find all the square roots, .06's is 0.24, which is the closest out of all of the options to the graph.
x 21
----- = -----
110 100
Cross multiplication:
110 x 21 / 100
= 23.1
About 23 of the pencils are blue.
Answer:
Step-by-step explanation:
1) False: The function is decreasing (because the base, 1/3, is between 0 and 1).
2) True: The function is decreasing (see #1, above)
3) False: There is no x-intercept.
4) True: If x is 0, then y = (1/3)^0 = 1.
5) False: the range consists of the set of all real numbers greater than zero.
From the number given is appears the rule is y = 2x + 1
This works for all three:
17 = 2(8) + 1
1 = 2(0) + 1
15 = 2(7)+1
Answer: x = 1
Explanation:
g(x) = 5x + 2
g(x) = 7
=> 5x + 2 = 7
5x = 7 - 2
5x = 5
x = 5/5 = 1
