Answer:
(6 , -1)
Step-by-step explanation:
2x+ y = 11 ----------------(I)
y = 11 - 2x --------------------(II)

Multiply the whole equation by 2

x - 10y = 16 --------------------(III)
Substitute y = 11- 2x in equation (III)
x - 10(11 - 2x) = 16
x - 110 + 20x = 16
21x - 110 = 16
21x = 16 +110
21x = 126
x = 126/21
x = 6
Plugin x = 6 in equation (II)
y = 11 - 2*6
y = 11 - 12
y = -1
It is increase, because 15 is less than 18. Other way around, if the question is 18 to 15 yards, then that would be decrease, because it is getting smaller.
Answer:
-26.5
Step-by-step explanation:
-12.3 - 14.2 =
in addition or subtraction, if the signs are alike, u add them and keep the same sign
so, -12.3 - 14.2 = - 26.5
but dont get this rule confused with multiplying or dividing...because those have different rules
22^7 - 22^4 = 2,494,123,632 .
Please say brainliest.
The answer is yes.
Plug 4 in for the value of n so you have 4+8 is less than it equal to 13. And since 12 is less than 13 it is true, and a solution to the inequality.
