Lots of red herrings in this question! The beacon is circular, so you need to find the area of a circle with a diameter of 36 inches.
Area of a circle = pi x radius^2
remember radius is half the diameter!
Answer:
4y = x - 17
Step-by-step explanation:
First off, in the equation given : 2x + 5y = 6 , make y the subject of the formula which will give y =
+
which make the gradient, m, the coefficient of x =
. Since the line we're looking for is parallel to the one we were given, their respective gradients would be the same. (If they were perpendicular, the gradient of the new line would be a negative inverse of the given line)
Then you proceed to use the one-point formula : y - y₀ = m(x - x₀), where y₀ = 3 and x₀ = 5 from the point it goes through (5, 3)
y - 3 =
(x - 5); y - 3 =
-
; y =
-
+3
y =
-
; y =
; 4y = x - 17
Answer:
one million one hundred thousand three hundred
Remark
You can just look at the graph to find out the y intercept. The y intercept is the point where x = 0. The point for the y intercept is (0,-2). So B is definitely wrong.
To get the slope, you can just use the x intercept which is (-3,0)
When y = 0, x = - 3. We need to do a little calculation to get the slope.
So far what we have is
y = mx - 2
y = 0
x = -3
0 = m(-3) - 2 Add 2 to both sides.
2 = m(-3) Divide by - 3
2/-3 = m
Now let's see what we have.
y = -2/3x - 2
C is the correct answer
