Step-by-step explanation:
Answer:
Perimeter is 100
Step-by-step explanation:
A^2 + B^2 = C^2
20^2 + 15^2 = C^2
200 + 225 = C^2
C^2 = 625
C=25
Perimeter is 100
To get this you would do the 25 X 4 = 100 yds
Hope this helps :)
Answer:
A linear line downwards
Step-by-step explanation:
You change the equation to y = 5 - 1/2x and as x increases, y becomes a smaller number, making the line go downwards as x increases (so it kinda looks like a \ on a graph). To find 10 solutions, just plug in values for x and make coords, ie (1, 4.5) from y = 5 - 1/2.
X=-3 because first substitute the value of y into the original equation -2x-3=x+6 then isolate the variables -2x-x=6+3 which is -3x=9 then we can divide x=9/-3 which =-3
Answer: 
Step-by-step explanation:
You can draw a right triangle (Observe the figure attached. It is not drawn to scale), where "x" is the the amount of meters the street rises over a horizontal distance of 120 meters.
You need to use the following Trigonometric Identity:
In this case, you can identify that:
Then, knowing these values, you can substitute them into:
And finally, you must solve for "x" in order to find its value.
You get this result:
