Answer: The answer is 9.3 if the coefficient is 10, but the answer is -80/3 if the coefficient is 3

Step-by-step explanation:

Let's solve your equation step-by-step.

3+90=10x

Step 1: Simplify both sides of the equation.

3+90=10x

(3+90)=10x(Combine Like Terms)

93=10x

Step 2: Flip the equation.

10x=93

Step 3: Divide both sides by 10.

10x

Answer:

Let's solve your equation step-by-step.

3x+90=10

Step 1: Subtract 90 from both sides.

3x+90−90=10−90

3x=−80

Step 2: Divide both sides by 3.

−80

Answer:

−80

It could sometimes be proportional. The reasoning here is that if all the items have different prices it won't be, however if the items you are ordering all have the same price they will be!

Answer:

y = 5cos(πx/4) +11

Step-by-step explanation:

The radius is 5 ft, so that will be the multiplier of the trig function.

The car starts at the top of the wheel, so the appropriate trig function is cosine, which is 1 (its maximum value) when its argument is zero.

The period is 8 seconds, so the argument of the cosine function will be 2π(x/8) = πx/4. This changes by 2π when x changes by 8.

The centerline of the wheel is the sum of the minimum and the radius, so is 6+5 = 11 ft. This is the offset of the scaled cosine function.

Putting that all together, you get

... y = 5cos(π/4x) + 11

_____

The answer selections don't seem to consistently identify the argument of the trig function properly. We assume that π/4(x) means (πx/4), where this product is the argument of the trig function.
