So you need help with creating the table ?
Answer: y = 7
Step-by-step explanation:
Step 1) plug in 3 for y and 9 for x in the direct variation formula, which is y = kx
3 = k(9)
Step 2) Solve for k
3 = k(9) (Divide by 9 on both sides)
3/9 = k (Now simplify 3/9)
1/3 = k. So k = 1/3
*just FYI: “k” is the constant of variation.
Step 3) use the equation y = kx and plug in 1/3 for k
y = 1/3x
Step 4) using the equation y = 1/3x, plug in 21 for x.
y = 1/3(21) (1/3*21 is the same as 21/3)
y = 21/3 (21/3 = 7)
y = 7. So that’s you’re answer! When x=21, y=7 because 7 is 1/3 of 21!
Hope this helps! My best wishes to you as you go through school!
B + f = 8
where b is the current bus fare and f the current ferry fare.
1.10b + 1.25f= 9.25. Replace f with 8- b:
1.10b + 1.25(8-b) = 9.25
Then:
1.10b-1.25b + 10 = 9.25, and so
-0.15b = -0.75. Then b = -0.75 / (-0.15) = 5
The bus fare is current $5, and so the ferry fare is $3.

Tangent is one of the simplest trigonometric functions which relates the sides of the triangle. This function is the ratio between the measure of the side opposite to the angle and the side adjacent to it. This can be calculated through the reverse equation of,
tan⁻¹(0.78) = A
The value of A in the equation to the nearest hundredth is <em>37.95°</em>.
