Answer:
A) 150
B)30
Step-by-step explanation:
-- Find any point where y=4
-- Find another point where y=4
-- With your ruler, draw a line between the two points.
You have a horizontal line, and every point on it has y=4 no matter what 'x' is.
The equation for every straight line is [ y = mx+b ].
This is the line where (m = 0) and (b = 4).
Answer:
x = -6 ±sqrt(251)
Step-by-step explanation:
3(x+6)^2=753
Divide each side by 3
3/3(x+6)^2=753/3
(x+6)^2=251
Take the square root of each side
sqrt((x+6)^2)=±sqrt(251)
x+6 = ±sqrt(251)
Subtract 6 from each side
x+6-6 = -6 ±sqrt(251)
x = -6 ±sqrt(251)
Answer: 15 1/2
Step-by-step explanation: There are two 1/2 s so 1/2 + 1/2 is 2/2 or 1 whole. Next is 1. There are 4 ones. 1+1+1+1 = 4. There is one 1 1/2. There are two 2. 2+2 is 4. There are two 2 1/2 so 2 1/2 + 2 1/2 is 4 2/2 which is 5. Now you have to add all the answers together. 1 +4+ 1 1/2 +4+5 which is 15 and 1/2. 15 1/2 is the answer.
Option A.
Step-by-step explanation:
Rational numbers -
- Numbers that can be written as fraction of two whole numbers.
- They can be positive, negative or zero.
- They are numbers that can be written as fractions.
- So, options B and C are examples of rational numbers.
Vinculum or Bar numbers -
- These numbers are repeating decimals.
- They are written with a line or a bar on top of the repeating numbers.
- Bar numbers are irrational numbers.
- So, option A is not a rational number.
