Answer:
Step-by-step explanation:
This relation (this group of points) is NOT a function. In order to be a function, every x-value (the first number in the pair) can only be paired up with one y-value (only one partner for the x)
In this relation, -6 is paired up with four different y-values (four different partners!)
If you plotted these points on a graph, you would see they are all lined up in a vertical line. If you have learned about the vertical line test, you will see that a vertical line goes through all four points. This set of points fails the vertical line test. To be a function, a vertical line can only touch the points one at a time.
To be a function, every x can only have one y partner.
Your equation is: 5h + 4 = 10h + 8
First subtract 5h from both sides:(So that variable terms stays in one side only)
=> 5h + 4 -5h = 10h + 8 -5h
=> 4 = 5h + 8
Now subtract 8 from both sides:(So constant term stays in the opposite side of variable terms)
=> 4 - 8 = 5h + 8 - 8
=> -4 = 5h
Now divide both sides by 5:(division by coefficient of variable)
=> -4/5 = 5h/5
=> -4/5 = h
=> h = -4/5 = -0.8
Answer: D
Step-by-step explanation:
Use SOHCAHTOA
We are given the opposite of the angle and the hypotenuse. We can use the sine function to acquire the value of x°.
sin(x) = 7/13
Take the inverse sine on both sides by using a calculator to get:
x = 32.58°
Answer:
yes
Step-by-step explanation:
because both of them are horizontal straight lines
