Answer:

X would have to equal 6. To work it out, you subtract 4 from each side to cancel out the 4. -x = -6. You have to make -x just x so you × each side by -1. You get x = 6.

The average cost c (in dollars) to manufacture x T-shirts is given by the function c=5x+410x. Express the number of T-shirts in

nikklg [1K]

Answer:

x = $\frac{C}{415}$ will be the expression.

Step-by-step explanation:

In this question an expression has been given which represents the relation between average cost C and number of T shirts (x) manufactured.

We have to solve this expression for the value of x (number of T-shirts) in terms of C.

C = 5x + 410x

C = 415x

x = $\frac{C}{415}$

Therefore, x = $\frac{C}{415}$ will be expression showing the number of T-shirts in terms of average cost.

What am I supposed to put as an answer?? this is so confusing

kaheart [24]

The 'i' should go in front of the square root, not inside it.

So the answer should be $i\sqrt{15}$

--------------

The way they wrote the expression $\sqrt{15}i$ is bit misleading as it might imply that the 'i' is under the square root. However the square root ends after the "5". It might be better to say $(\sqrt{15})i$ so there is clearer separation. But sticking the "i" in front is also a valid option.
