1:
2x-y=7
Subtract 2x from both sides and you get:
-y=-2x+7
Divide both sides by negative 1
y=2x-7
2:
Minus
the second choice, and the last choice are correct.
the first one, x can be any number.
the second one, x can be any number but not -1(the denominator cannot be 0)
the third one, x has to be ≥ 1/2, because 2x-1 cannot be negative.
the fourth one, x can be any number but not -1 or -4
the last one, x can be any number but not -3
Answer:
After population (A) = 62,902 (Approx)
Step-by-step explanation:
Given:
Current population (P) = 19613
Number of years (n) = 2020 - 2000 = 20 year
Rate of growth (r) = 6% = 0.06
Find:
After population (A)
Computation:
210/600 = 35% B
1/4 of 600 = 150 C
Vertical line are represented by x = a number....that number being the x value in ur set of points
so ur equation is : x = -7
