12 would be the y intercept because x is 0 and y is 12
Answer:
Step-by-step explanation:
This is segment addition in Geometry. Picture a straight line with endpoints A and C. B is a point stuck somewhere between them. The length of AC then is equal to the length of AB plus the length of BC. In algebraic terms:
AC = AB + BC. Filling in from the problem:
81 = 2x + 1 + 6x and combine like terms:
81 = 8x + 1 and subtract over the 1:
80 = 8x and divide by 8 to find
x = 10.
Answer:
The answer is -√7
Step-by-step explanation:
∵ The polynomial has roots 3 and √7
∴ It must have root -√7 the conjugate of √7
∴ The roots of f(x) are 3 , √7 , -√7
(one rational and two irrational conjugate to each other)
Answer:
numbers that cannot be reduced when squared, ex: 1,3,5,
Step-by-step explanation:
These numbers factors are themselves and 1, to find if it is a prime number you can try to find the factors and if it is just itself and 1, then it is a prime number
