Answer:c. Y=(x-3)^2-2
Step-by-step explanation: y=(x-3)^2-2
Y=x^2-6x+7
Answer:
√85 units
Step-by-step explanation:
If we move from (-1, 4) to (6,-2), we see x (the run) increasing by 7 and y (the rise) decreasing by 6.
The distance between these two points is found using the Pythagorean Theorem:
d = √ [7² + 6²] = √85 units (we cannot leave off the " √ " operator). Compare this to the 3rd answer choice.
Answer:
C
Step-by-step explanation:
Given
2x² - x - 6
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 6 = - 12 and sum = - 1
The factors are - 4 and + 3
Use these factors to split the x- term
2x² - 4x + 3x - 6 ( factor the first/second and third/fourth terms )
= 2x(x - 2) + 3(x - 2) ← factor out (x - 2) from each term
= (x - 2)(2x + 3) ← in factored form
Thus 2x + 3 is a factor → C
