Part A: The x-intercepts of the graph are (-2, 0) and (2.5, 0). 2x² - x - 10 = 0 2x² - 5x + 4x - 10 = 0 x(2x - 5) + 2(2x - 5) = 0 (x + 2)(2x - 5) = 0 x = -2, 5/2 or 2.5 Part B: The vertex is going to be the minimum of the function. The coordinates are (0.25, -10.125). Vertex = (h,k) h = midpoint of the x-intercepts (because of symmetry) h = (-2 + 5/2) = 1/4 k = f(1/4) k = 2(1/4)² - 1/4 - 10 = -81/8 Vertex: (0.25, -10.125). y-intercept: when x = 0 2(0)² - 0 - 10 = -10 Part C: To graph f(x), I would draw a line connecting the x-intercepts, vertex and the y-intercept using the points (-2,0), (0,-10), (0.25, -10.125) and (2.5,0). These points are the answers from part A and B and that is why I can use them to draw the graph.

The model below represents an equation. Which value of X makes the equation true?

Answers

Answer:

A) x = -1/4

Step-by-step explanation:

There are 4 x's, 4 1's on one side of the equation, and 3 1's on the other side

4x + 4 = 3

Subtract 4 on both sides

4x = -1

Divide each side by 4

18. C

Step-by-step explanation:

The greater the negative number, the less the number values. -10 is smaller than -8 because -10 is farther away from the number line to the left.

Go in terms of the tenths place. If its smaller than the number will be less than the bigger numbers. 0.227 is bigger than 0.18 because it has a 2 in the tenths place.

A discount movie pass cost 10.99. With the pass,movie tickets cost 4.25 dollars each. Feen spent a total of 61.99 dollars on the pass and the movie tickets. write an equation to determine how many movie fren watched

Answers

The equation would be (61.99-10.99)/4.25= x
You subtract the price of the pass from the total (61.99-10.99) then you’d divide that by 4.25 to see how many movies she watched
61.99-10.99= 51... 51/4.25= 12 she watched a total of 12 movies

Sketch the graph of 2y=f(3x-6) -2

Answers

Um i think 2yyyy =f 3x-6

The required graph is attached below, which represents the given function f(x)= 3x - 6y - 2.

The below graph of the function f(x) = 3x - 6y - 2 represents a straight line in a two-dimensional coordinate system.

The equation is in standard form, where x and y are variables and the equation is equal to a constant value (-2 in this case).

To graph this equation, we can rearrange it to the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

By isolating y in the equation, we get y = (3/6)x - 2/6, which simplifies to y = (1/2)x - 1/3.

The slope of the line is 1/2, meaning for every increase of 1 in the x-coordinate, the y-coordinate increases by 1/2.

The y-intercept is -1/3, which is where the line crosses the y-axis.

Answers

Answer:

6 units to the right

Step-by-step explanation:

i added it to a graph.

Answer: You can use the distance formula to find the distance between any two points ion the plane. In this case, look carefully at the coordinates:

R(-1, 7) and T(-7, 7), Notice they both have y-coordinate 7. That means they are both on the same horizontal line. To find their distance, just subtract -7 from -1 and take the absolute value.

|-1 - (-7)| = |-1 + 7| = |6| = 6

The distance is 6 units

What is a reciprocal?

The definition of reciprocal in mathematics is the inverse of a value or a number. If n is a real number, then 1/n will be n's reciprocal.

Given:

The number is 7.

Let n be the reciprocal of 7.

If n is a real number, then 1/n will be n's reciprocal.

To find the reciprocal of 7:

We need the value that can give us 1 when multiplied by 7.

That means,

n x 7 = 1

Divide by 7 to both sides,

n = 1/7

Therefore, the reciprocal is 1/7.

Erwin began the month with a bank balance of $0. His bank statement shows one credit (+) and one debit (-). HIs balance at the end of the month was $15. What could be the amounts shown as Erwin's bank statement. Explain how you got your answer.

Answers

Answer:

Credit ⇒ 45

Debit ⇒ $30

Step-by-step explanation:

Credit = $45

Debit = $30

When an account balance increases it means that it has been credited and when it decreases, it has been debited.

The beginning balance here is $0 and the closing balance is $15.

There were 2 transactions, one credit and one debit.

For the closing balance to be $15, the Credit amount must have been $15 more than the Debit amount.
