Answer:
The standard form of the quadratic equation is x² + 3·x - 4 = 0
Step-by-step explanation:
The standard form of a quadratic equation is a·x² + b·x + c = 0
Given that the expression of the quadratic equation is (x + 4)·(x - 1) = y, we can write the given expression in standard form by expanding, and equating the result to zero as follows;
(x + 4)·(x - 1) = x² - x + 4·x - 4 = x² + 3·x - 4 = 0
The standard form of the quadratic equation is x² + 3·x - 4 = 0
The graph of the equation created with MS Excel is attached
Answer:
x and y are the input and output of the function. The graph attached is all the values of x and y. For a specific value, more information is needed.
Step-by-step explanation:
56x+34y=4376 is a linear function with two variables. It represents the rule between inputs (x) and outputs (y). To find all its values of x and y, graph the equation.
Answer:
Tina scored 82.85% in the given assignment.
Step-by-step explanation:
Total marks Tina scored in the assignment = 29
Maximum marks in the assignment = 35
Now,
=
or, the percentage obtained = 82.85%
