Answer:
A) y = 8.63 x
B) $224.38
Step-by-step explanation:
The the average monthly cost = (147.98+152.17+165.63)/3 = $155.26
So, For 18 employees the average monthly cost = $155.26
Let the equation that can be used to estimate y, the average monthly cost, in dollars, to buy lunch for x employees. ⇒ y = mx
For x = 18 , y = $155.26
So, m = y/x = $155.26/18 ≈ $8.63
∴ y = 8.63 x
To find the total cost for 26 employees.
∴ x = 26
∴ y = 8.63 * 26 = 224.38
The total cost of a monthly lunch for 26 employees = $224.38

True : A function must have a different output
Answer:
150°
Step-by-step explanation:
The two angles form a straight line (the arrows on the ends of the lines tells you that it's a straight line), so they form 180° when added together.
The ratio 1 : 5 tells us that there are 6 total parts made up by the angles. Find the value of one part, then you can find the value of <ZXY
To do this, divide 180° by 6 to find out what one part equals.
180°/6 = 30°
So one part is 30°
<WXZ is 30° since it makes up one part
<ZXY is 150° since it makes up 5 parts { (30°)(5) = 150° }
