Find the domain of the funtion 4/x-7

1 answer:

5 0

Domain means which values the function can have which make it true or Possible to solve

So all you got to do is set the denominator = to 0 and solve for x
You will get x=7

4/(7-7) is not possible

So x cannot equal to 7 because you cant divide a number by 0!

Answer:

Part A:

- angle ACB= 60° (ABC equilateral triangle.)

- Angle ECD=EDC= (180°-32°)/2= 148/2= 74° (sum of angles in a triangle is equal to 180, and triangle ECD is isosceles since it's given that CE=DE.

- x= 180°-(60°+74°)

= 180°-134°

= 46°

x= 46°

Part B:

120°

Answer:

$x = - \frac{25}{3}$

Step-by-step explanation:

$\frac{10}{3} = \frac{x}{( - \frac{5}{2}) }$

<h3>i) simplify the complex fraction</h3>

$\frac{10}{3} = - \frac{2x}{5}$

<h3>ii) simplify the equation using cross multiplication</h3>

$5(10) = - 2x(3)$

$50 = - 6x$

<h3>iii) swap the sides of the equation</h3>

$- 6x = 50$

<h3>iv) divide both sides of the equation by -6</h3>

$\frac{ - 6x}{ - 6} = \frac{50}{ - 6}$

$x = - \frac{50}{6}$

<h3>v) simplify the fraction</h3>

$x = - \frac{25}{3}$

In 2013 nyc had 66.37 inches of precipitation what is that amount of precipitation to the nearest inch

V125BC [204]

Since we are rounding to the nearest inch, we want to look at the tenths place. The rule for rounding is 5 and up, we round up, 4 and below, stay. Since 3 is below 5, we stay. Therefore your answer should be 66 inches of precipitation. Hope this helps!
