To make sure we don't have negatives under the square root, we specify that

(x is greater than or equal to 0). We'll use this fact later on
--------------------------------------------
Start with the given inequality

and square both sides to get

. Couple this with the fact that

means we have this compound inequality

What does this mean? It means that we can pick any value from 0 to 49 (including both endpoints) and it will be a solution to the inequality. This applies to the values
49, 48 and 44Answers: Choice C, Choice D, Choice E
Answer:
y < 5
Step-by-step explanation:
22-3y>7
1.) -3y > 7-22 subtract both sides by 22 so you get -3y > -15
2. ) y < -5 divide both sides by -3
then flip the inequality sign because you're dividing by a negative number.
To find k, divide both sides by 1/4
K = 2/3 / 1/4
When dividing by a fraction flip the second fraction over then multiply:
K = 2/3 x 4/1 = (2 x 4) / (3 x 1) = 8/3
K = 8/3 = 2 and 2/3
Answer:
maybe number 2
Step-by-step explanation:
because if 2+k=18 then there is no other k there and where did the additional 2 come from ?and 2k=18 then value of k is 9 + there is balance.I may be wrong correct me but i think it is no.2
Answer:
36.87°
Step-by-step explanation:
cos C = 4/5
arccos C = 36.87
