Divide both sides by 25 to isolate x:
105% as a decimal would be 1.05 in decimal form
Answer:
a. $500
b. $250
Step-by-step explanation:
a. For zero items produced, cost will be-

b. For zero items produced, cost will be-

c. If 

∴ domain for cost function will be
and range will be 100
Answer:
<u>The domain is the set of x-values:</u>
<u>The range is the set of y-values:</u>
This can be a function as each x- value has exactly one corresponding y- value.
Option A is true because the sum of angles in a triangle is 180, so we can rule that one out immediately.
We can solve for x for the other 3 options by setting up this equation:
7x+2 + 4x+7 + 8x = 180 | Simplify
19x + 9 = 180 | Subtract 9
19x = 171 | Divide by 19
x=9
Now we can substitute x into all the values:
<J = 7x+2 = 65
<L = 4x+7 = 43
<K = 8x = 72
Looking at the options again, we can see that A, B, and D are true, leaving C to be false.
