Answer:
Step-by-step explanation:
sina=opposite/hypotenuse=7/25
cosa=adjacent/hypotenuse=24/25
tana=opposite/adjacent=7/24
sinc=opposite/hypotenuse=24/25
cosc=adjacent/hypotenuse=7/25
tanc=opposite/adjacent=24/7
Answer:
(x+7)·.2
Step-by-step explanation:
The sum of x and 7 is x+7. The word sum indicates addition. Then it says multiply by 1/5, so i converted it to decimal which is .2

Answer:
The first answer choice, (-14) + 8
Step-by-step explanation:
1. Solve (-14) - (-8)
(-14) - (-8) = -6
2. Solve the answer choices
(-14) + 8= -6
14 - (-8)= 22
14 + (-8)= 6
(-14) + (-8)= -22

Answer: Choice D</h3>
======================================================
Explanation:
The inequality sign has an "or equal to", which means the boundary line will be solid. We can rule out choices B and C because they have dashed boundary lines.
A solid boundary line means that points on the boundary are part of the solution set.
Now let's see what happens when we plug in a point like (x,y) = (4,0). This will tell us how to shade the blue region.

This is false because -20 is not larger than -1. It's the other way around.
This tells us the point (4,0) is not in the blue shaded region, and it's not on the boundary line either. We can rule out choice A because of this.
The only thing left is choice D, which is the final answer. I recommend plugging a point from this region into the inequality to confirm we have a true statement.
