How many fractions are equivalent to 4/5?

1 answer:

7 0

There is an infinite amount of fractions equivalent to the one given. All you have to do to find a fraction equivalent is multiply the numerator and denominator by the same number, and when you get the resulting fraction it can be simplified to become the original again, therefore making it the same.

The spoke of a wheel reaches from the center of the wheel to its rim. If the circumference of the rim of the wheel is 48 inches,

Dennis_Churaev [7]

<span>The spoke of a wheel reaches from the center of the wheel to its rim implies that the spoke of the wheel is describes the radius to the wheel. The circumference of a circle is given by C = 2πr. i.e. 48 = 2 x 3.14r = 6.28r => r = 48 / 6.28 = 7.64 inches.Hope this helps. Let me know if you need additional help!</span><span />

For 25 points

tigry1 [53]

The required domain of the inverse function is x ≤ 0. Hence option D is correct.

f(x) = -x^2

<h3>What are functions?</h3>

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is independent variable while Y is dependent variable.

Inverse of function f(x) = -x^2
y = -x^2
x = √-y
Now,
Inverse function of f(x) is √-x
Its domain is define as less than or equal to zero.

Thus, the required domain of the inverse function is x ≤ 0.

Which function in vertex form is equivalent to f(x) = 4 + x2 – 2x?

Alexus [3.1K]

<h3>Answer:</h3>

option A

f(x) = (x – 1)2 + 3

<h3>Step-by-step explanation:</h3>

Given in the question a function,

f(x) = 4 + x² – 2x

Step 1

f(x) = 4 + x² – 2x

here a = 1

b = -2

c = 4

Step 2

x = -b/2a

h = -(-2)/2(1)

h = 2/2

h = 1

Step 3

Find k

k = 4 + 1² – 2(1)

k = 3

Step 4

To convert a quadratic from y = ax² + bx + c form to vertex form,

y = a(x - h)²+ k

y = 1(x - 1)² + 3

y = (x - 1)² + 3

Write the point-slope form of the equation of the line that passes through the points (-3, 5) and (-1, 4). Please answer quickly

Oksanka [162]

The point-slope form of the equation of a line is

$y - y_1 = m(x - x_1)$

where

$(x_1, y_1)$

is a point on the line, and

$m$

is the slope of the line.

We can use either one of the two given points as the point on the line.
We also need to find the slope. We can use the coordinates of the two given points to find the slope of the line.

The slope of the line that passes through points

$(x_1, y_1)$ and $(x_2, y_2)$

is

$m = \dfrac{y_2 - y_1}{x_2 - x_1}$

Let's find the slope using (-3, 5) as point 1 and (-1, 4) as point 2.

$m = \dfrac{4 - 5}{-1 - (-3)} = \dfrac{-1}{-1 + 3} = \dfrac{-1}{2} = -\dfrac{1}{2}$

Now we use the point-slope formula with point 1 and the slope we found just above.

$y - y_1 = m(x - x_1)$

$y - 5 = -\dfrac{1}{2}(x - (-3))$
