Answer:
You have to graph and label the points
Step-by-step explanation:
3x-5 is just a straight line which is lesser than or equal to -1 so that is a closed circle
-2x+3 is another straight line which is (both open circle) which its domain is restricted from -1 to 4
2 is just a horizontal line starting at (closed circle) 4, it is greater than also.
If you don't understand the the constants (the numbers on their own) just a vertical translation.
If the cross either the x or y axis, you have to find that too, im pretty sure.
To find the y axis intercept, make x = 0 and solve for y
and to find the x axis intercept, make y = 0 and solve for x
Let x be the unknown angle.
We know that x+50=120 because the value of an exterior angle of a triangle is equal to the sum of the other 2 interior angles.
x+50 = 120
Subtract both sides by 50
x = 70
The value of the unknown angle is 70 degrees.
Have an awesome day! :)
3*2=6
6-x-2=0
4=x
The answer is 4
Answer 512 mph
Divide 1,792 miles by 3.5 hours to get average rate
average rate = 1792/3.5 = 512mph
