Find the y-intercept of f(x)=2x^2-2x+1
Answers
The y-intercept of the function f(x) = 2x^2 - 2x + 1 is (y = 1), as determined by substituting (x = 0) into the function, resulting in (f(0) = 1). This point represents the value of the function when it intersects the y-axis.
- To find the y-intercept of the quadratic function f(x) = 2x^2 - 2x + 1, we need to determine the value of f(x) when x is equal to 0. The y-intercept occurs when x = 0 because it represents the point where the graph of the function intersects the y-axis.
- So, substitute x = 0 into the function:
- f(0) = 2(0)^2 - 2(0) + 1
- f(0) = 0 - 0 + 1
- f(0) = 1
- Therefore, when x = 0, the value of the function f(x) is 1. This is the y-coordinate of the y-intercept. The point representing the y-intercept is (0, 1).
- So, the y-intercept of the function f(x) = 2x^2 - 2x + 1 is 1. This means that the graph of the function intersects the y-axis at the point (0, 1).

The required formula width of the rectangle in terms of w is .
Given ,
The perimeter of a rectangle = p
Formula = P = 2l + 2w,
Where, l is the length of the rectangle and w is the width of the rectangle.
We have to find
The formula in terms of w width.
According to the question,
The formula of a rectangle is P (perimeter) = 2W (the two widths added together) + 2L (the two lengths added together).
Now ,
Let "x" is often used, and solve for x. You could keep W instead of X also.
P= 2x + 2L
isolate the 2x by subtracting2L from both sides.
P - 2L= 2x
Now isolate the x by dividing both sides by 2 and ,
Where, x = w,
Hence, The required formula width of the rectangle in terms of w is

These examples of a fact family with only two facts are 6 x 2 = 12, and 12 ÷ 2 = 6 using the number 6.
What is the number system?
A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.
In a fact family, there are three related math facts that share the same three numbers. In this case, the three numbers are 6, 2, and 12. The two facts are related to each other through the property of inverse operation of multiplication and division where the product of two numbers is 12 and the quotient of 12 and 2 is 6.
6 x 2 = 12
12 ÷ 2 = 6
This is an example of a fact family with only two facts, using the number 6. The first fact is 6 is multiplied by 2, which equals 12. The second fact is 12 is divided by 2, which also equals 6.

Answer:
-4x² + 10x + 4
Step-by-step explanation:
(-4x² + 3x - 5) - (-7x - 9)
-4x² + (3x - -7x) + (-5 - -9)
-4x² + (3x + 7x) + (-5 + 9)
-4x² + 10x + 4
Final answer:
To subtract – 7x – 9 from - 4x² + 3x – 5, we change the signs of all the terms in the second expression and then combine like terms. The final answer is -4x² + 10x + 4.
Explanation:
To subtract – 7x – 9 from - 4x² + 3x – 5, you simply replace the minus sign before the second expression (– 7x – 9) with a plus sign, and then change the signs of all the terms in that expression. This is analogous to the subtraction of scalars, where for example, 5–2 equals 5+(-2).
Thus, the expression becomes: -4x² + 3x - 5 + 7x + 9. Now, you simply combine like terms. The 3x and 7x can be combined to get 10x, and -5 and 9 can be combined to get 4. The final answer is -4x² + 10x + 4.

Area (Square) = length times width
1yard^2⇒3feet^2⇒9^2
Then take 9 and divide 180 sq feet from it
180 ÷ 9 = 20 sq yards
Then multiply 20 by $15
20×$15=$300
Answer:
$300
So
3 feet = 1 yard
9 square feet = 1 square yard
180/9 = 20 square yards
20 x 15 = $300
which is your final answer (:
