Answer:
The correct option is C) 0.25.
Step-by-step explanation:
Consider the provided numbers.
We need to find the difference using the number line.
Open the parentheses:
This indicate that the arrow will starts from -0.25 and move 0.5 units to right. Arrow will move right because 0.5 is a positive number.
The difference using the number line is shown in figure 1.
Hence the correct option is C) 0.25.
We divide both sides by 5 so we can eliminate the parenthesis:
We rearrange the terms so the terms with the unkown variable y are on the left side and the other ones on the right side:
y - 10 = -1
↓ <em>adding 10 both sides</em>
y - 10 + 10 = -1 + 10
y + 0 = 9
y = 9
<h2>Answer: y = 9</h2>Using the completing the square method, for the equation, we have the zeros as <u>x = √26 + 4 and x = 4 - √26</u>
<h3>How can the zeros be found using completing the square method?</h3>The given equation is presented as follows
Which, by completing the square, gives;
