Answer:
It would be answer A, in y=x+7, the value of y would be 7 more than the value of x. That is true
The value is of this equation is -3.75
I'd turn the fraction into a decimal. 56.25% but the answer in simplest form is <span>-5/7(2/5). i hope this helped you. :)</span>
Answer:
Step-by-step explanation:
Given;
x² - 2x - 1 = 0
Solve by completing the square method;
⇒ take the constant to the right hand side of the equation.
x² - 2x = 1
⇒ take half of coefficient of x = ¹/₂ x -2 = -1
⇒ square half of coefficient of x and add it to the both sides of the equation
⇒ take the square root of both sides;
Therefore, option B is the right solution.
