Answer:
70 students
Step-by-step explanation:
As, 30% Mike surveyed
And these 30% are 21 students
So 30% of X = 21
= 30/100 x X = 21
= 30X = 2100
So X = 2100/30
X = 70
So 70 students were surveyed
Find the difference between the existing terms:
-8 / -4 = 2
-16/-8 = 2
This means the next term is the previous term multiplied by 2:
The first term is given as -4
You would start with the first term ( -4) then multiply it by the difference of terms ( 2) raised to the nth term (n) minus 1.
An = -4 * 2^n-1
The answer is A

Answer:
Red Line: y=4
Blue Line: y=-2
Green Line: x=-1
Yellow Line: x=6
Step-by-step explanation:
Red line: the line crosses through 4 on the y axis. Therefore, y=4.
Blue line: the line crosses through -2 on the y axis. Therefore, y=-2.
Green line: the line crosses through -1 on the x axis. Therefore, x=-1.
Yellow line: the line crosses through 6 on the x axis. Therefore, x=6.
This is a bit confusing because when you see a horizontal line your mind might assume it would be an x=. Yet, it is the opposite. Hope this helps!
Answer:
19 and 2
Step-by-step explanation:
Let x represent the first number and y represents second number
x + y = 19
x - y = 17 add two equations up
2x = 36 divide both sides by 2
x = 19 and since the difference is 17 the other number is 2
