I THINK it might be y=cos(x)+2. Don’t quote me on that and you might wanna check with someone else
Answer:
21 Feet
Step-by-step explanation:
7 yards is equal to 21 feet
(8x + 2y) - (7x + 2y) = 30 - 24
X = 6

from 
then;

Remove the bracket we have;

Like terms are those terms which have same variable to the same power.
Combine like terms;

Therefore, Subtracting
from
we get 
Answer:
The correct answer is 2x - y - 1 = 0
Step-by-step explanation:
To find this, use the ordered pair (1, 1) in any of the equations. If it results in a true statement then this can be an equation.
2x - y - 1 = 0
2(1) - (1) - 1 = 0
2 - 1 - 1 = 0
0 = 0 (TRUE STATEMENT)
