How do you find the x-coordinate of the vertex of a parabola if you only have the equation

Answers

Answer 1

Answer:

Answer and Explanation:

The vertex formula is derived from the completing-the-square process, just as is the Quadratic Formula. In each case, memorization is probably simpler than completing the square.) For a given quadratic y = ax2 + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k.

Which fraction is equivalent to 3/5?

Answers

6/10
9/15
and so on with the factors of 3 and 5.
These numbers simplified is 3/5

To find an equivalent fraction to 3/5 we can multiply the numerator and the denominator by any same number. lets do it with 2:-

$(3)/(5)$

$(3*3)/(5*3)= (9)/(15)$

So, a fraction equilateral tt 3/5 is 9/15.

Find the slope of the line that goes through the given points.
(7,2) and (5,2)

Answers

Answer: 0

Step-by-step explanation:

describes a horizontal line

so slope = 0

Answer:

0/2

Step-by-step explanation:

you have to subtract the x's and then then the y's, y is always on top. So, y=2-2/ x= 7-5 making 0/2 When the 0 is on the "top" of the fraction, that would mean that the two y-values are the same.

What is the y-intercept of a line that has a slope of 1/4 and passes through point (8,3)?

Answers

The slope-intercept form: y = mx + b

m - a slope

b - y-intercept

We have a slope m = 1/4. Substitute: y = 1/4 x + b

We know, the line passes through point (8, 3) → x = 8, y = 3.

Put the values of x and y to the equation of the line:

1/4 · 8 + b = 3

2 + b = 3 |-2

b = 1

Answer: y-intercept is (0, 1)

The y-intercept of a line with a slope of 1/4 and which passes through point (8,3) is 1.

What is the y-intercept of the given line?

The equation of a line in slope in slope intercept form is expressed as:

y = mx + b

Where m is slope and b is the y-intercept.

Given the data in the question:

The line has a slope of 1/4 and passes through point (8,3).

x = 8, y = 3, m = 1/4

Plug the given values into the above formula and for the y-intercept 'b'.

y = mx + b

3 = (1/4 × 8 ) + b

Solve for b:

3 = 8/4 + b

3 = 2 + b

3 - 2 = 2 - 2 + b

1 = b

b = 1

Therefore, the y-intercept is 1.
