X = small boxes and y = large boxes
x + y = 17.....x = 17 - y
3x + 14y = 183
3(17 - y) + 14y = 183
51 - 3y + 14y = 183
-3y + 14y = 183 - 51
11y = 132
y = 132/11
y = 12 <=== large boxes (y) cost $ 12
x + y = 17
x + 12 = 17
x = 17 - 12
x = 5 <=== small boxes (x) cost $ 5
Answer:
7xy
Step-by-step explanation:
Answer:
value of X=180-(ABC + ACB)
=180-(42+90)
=180-132
=48
Answers:
Graph A is a function
Graph B is not a function
========================================================
Explanation:
To check if we have function or not, we apply the vertical line test. This test is where you ask yourself: "Is it possible to draw a single vertical line through more than one point on the curve?"
If the answer to that question is "yes it is possible", then we do not have a function. Graph B shows that we can draw a line through say x = 2 and have the vertical line intersect at points (2,2) and (2,4). The input x = 2 leads to multiple outputs y = 2 and y = 4 simultaneously. This is why graph B is not a function.
A function is only possible when any x input from the domain leads to exactly one y output in the range. Graph A is a function because we cannot draw a single vertical line to intersect through that curve more than once.
Answer: The initial number of shoes in the store is 300.
Step-by-step explanation:
Given : Kelly is a salesperson at a shoe store, where she must sell a pre-set number of pairs of shoes each month.
At the end of each work day the number of pairs of shoes that she has left to sell that month is given by the equation
, where S = Number of pair of shoes Kelly still needs to sell.
x = Number of days she has worked that month.
When x= 0 , we get S= 300
i.e. When she started working in that month , she has 300 pairs of shoes to sell.
Therefore , Number 300 means that the initial number of shoes in the store is 300
