Answer:

2

Step-by-step explanation:

sin²a + cos²a + sec²a - tan²a

sin²a + cos²a = 1

1 + tan²a = sec²a

So, sec²a - tan²a = 1

sin²a + cos²a + sec²a - tan²a

= 1 + 1 = 2

You are purchasing carpeting for an office building. The space to be carpeted is 30 feet by 50 feet. Company A charges $2.99 per
Umnica [9.8K]
Total area is 30 by 50 feet=1500 ft^2
So per square foot charges are 2.99$ and 200 additional
1500×2.99+200=4685$

And another charging 19.99$ per square yard
1 yard = 3feet
30 feet=10 yard
50 feet=50/3 yard
Area=50/3×10=500/3=166.66yards^2
So they will charge 166.66×19.99=3331.66+500= 3831.66$

So comapny B is cheaper and best deal

Y = x + 1
y = 2x - 1

basically we r going to sub in one y for another
x + 1 = 2x - 1
1 + 1 = 2x - x
2 = x

now we sub 2 in for x in either of the original equations to find y
y = x + 1
y = 2 + 1
y = 3

so ur solution is (2,3)
