C: (400-20x)(10+x)
x would represent how many dollar increases there was in the price and if 20 less are sold per dollar increase it would have to be (400-20x)(10+x)
to explain more. let’s say the price increases by 5 dollars. that would make x=5. so it would be (400-100) because 100 less shirts are sold. and (10+5) because you’re adding $5 to the price. If this doesn’t make sense lmk and I can re explain it

Determine the range of the function f (x) = x-4 when the domain is (1,5,6
aev [14]

For this case we have a function of the form y = f (x). Where:

f (x) = x-4

By definition, the domain of a function is represented by the set of values of the independent variable, x, for which the value of the variable y can be calculated.

For its part, the range is represented by the values of "and".

So:

f (1) = 1-4 = -3\\f (5) = 5-4 = 1\\f (6) = 6-4 = 2

Thus, the range is {-3,1,2}

Answer:

{-3,1,2}

Find x if EC is a bisector
OLga [1]

Answer:

<h2>x = 8</h2>

Step-by-step explanation:

If EC is a bisector of AC and CD, then AC is equal to CD.

Given AC = 3x+6 and CD = 2x + 14, since AC = CD then;

3x+6 = 2x+14

subtract 6 from both sides

3x+6-6 = 2x+14-6

3x = 2x+8

subtract 2x from both sides

3x-2x = 2x+8-2x

x = 8

<em>Hence the value of x is 8</em>
