Answer:
2/3
8/12
Step-by-step explanation:
You just divide each numerator 4 (5÷4) and each denominator by 6 (8÷6) and see if the numbers are the same.
5÷4=1.25
8÷6=1.33
They are not equivalent, so 5/8 is not correct
2÷4=0.5
3÷6=0.5
They are equivalent, so 2/3 is correct

1. Vertical 6, horizontal 10
6/10 = 3/5 slope
2. (Red) vertical -2, horizontal 3
-2/3 does not equal 3/5
3. (Blue) vertical 4, horizontal 6
4/6 = 2/3 but does not equal 3/5
Area =l×w
15.4=7×w
15.4/7=7/7w
2.2=w
Therefore the length of the height or width is 2.2ft
The graph for
f(x) = sin x
is a sinusoidal graph with the origin as the middle point and the value increases up to the maximum point before going down crossing the x-axis and reaching the minimum point before increasing again until it crosses the x-axis. The graph continues as a wave on both sides indefinitely.
f(x) = 3 sin 4x
has an amplitude of 3 or the highest point is 3 and a period of
Period = 2π/4 = π/2
f(x) = 3 sin 4x + 2
the graph is shifted 2 points upward.
Let us write the inverse variation in the given in an equation form,
a = k / b
where k is the constant of proportion.
If the value of b is double, there should be a corresponding change in a.
(x)(a) = k / 2b
(x)(a) = (1/2)(k/b)
The value of x is 1/2. Therefore, the value of a is halved.
