Answer:
Option A)

Step-by-step explanation:
We are given the following in the question:
Cost of orange/black shirt = $15
Cost of black/white shirt = $10
Amount of money to be raised is atleast $1000.
Let x be the amount of orange/black shirt and y be the amount of black/white shirt.
Thus, we can write the inequality:

That is the total cost of orange/black shirt and black/white shirt should be greater than or equal to $1000.
Thus, the correct answer is
Option A)

Answer: C
Explanation:
. there are multiple sockets that can be interchanged easily to accommodate many different size nuts and bolts
Sin(x) is a function bounded between -1 and 1. A value greater than 1 or smaller than -1 (-1.1, for instance) does not correspond to any real angle.
It then returns error
This basically means that you have to multiply the x and y values by 3. So 2 time 3 is 6. And -7 times 3 is -21. So the new coordinations are (6, -21)

Step-by-step explanation:
3x - 9 +2x + 9 = 2x - 2
5x = 2x - 2
5x - 2x = - 2
3x = - 2
x= - 2/ 3
