B. A = 1, B = 0, C = 8
C. A = 0, B = 1, C = 6
D. A = 0, B = 1, C = 8
Answer:
B
Step-by-step explanation:
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (8, 6) with x- coordinate 8, thus
x = 8 is the equation of the vertical line
In comparison to
Ax + By = C, then
A = 1, B = 0, C = 8, that is
x + 0 = 8
x = 8 being the required equation
Enter your answer, in simplified form, in the box.
B. (9x^2 + 1)(9x^2 – 1)
C. (3x^2 + 1)^3(3x – 1)
D. (9x^2 + 1)(3x + 1)(3x – 1)
Using this: a²-b²=(a+b)(a-b)
81x^4-1=
(9x²)²-1=
(9x²-1)(9x²+1)= (in the bold half we use the formula again)
(3x+1)(3x-1)(9x²+1)
So the answer is D
The fraction of a sandwich each friend get is 3 / 4.
An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number.
It is given that 8 friends share 6 sandwiches equally. The fraction will be calculated as below:-
Fraction = 6/8
Divide the number 6 by 8.
Fraction = 3/4
Therefore, the fraction of a sandwich each friend get is 3 / 4.
