Answer:

  y = 4/3(x +3)

Step-by-step explanation:

This sort of question is easily answered by making use of the point-slope form of the equation of a line:

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

You are given (h, k) = (-3, 0) and m = 4/3. Putting those into the above form gives ...

  y -0 = 4/3(x -(-3))

  y = 4/3(x +3) . . . . . . point-slope form equation

__

<em>Additional comment</em>

You can use the distributive property to eliminate the parentheses. That puts the equation into slope-intercept form.

  y = 4/3x +(4/3)(3)

  y = 4/3x +4 . . . . . . slope-intercept equation

__

You may find it useful to remember some different forms of the equation for a line:

  y = mx +b . . . . . line with slope m and y-intercept b

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

  ax +by = c . . . . standard form equation of a line, where a > 0, and a, b, c are mutually prime integers

Describe how you can tell that a fraction is reapeating and not terminating
GREYUIT [131]
<span> First, reduce the fraction to lowest terms, e.g. 8/6 = 4/3.

Look at the denominator. Split it into its prime factors. If its prime factors only consist of 2's and 5's, then it will be terminating.

Examples:
16 = 2 x 2 x 2 x 2, so terminating
25 = 5 x 5, so terminating
2000 = 2 x 1000 = 2 x (2 x 5) x (2 x 5) x (2 x 5), so terminating
12 = 2 x 3, so repeating (has prime factor 3, which is not 2 or 5)
13 = 13, so repeating (has prime factor 13, which is not 2 or 5)  Hope this helps!!

geniusboy [140]

Answer:

98 degrees

angles of a triangle always add up to 180 degrees. 41+41= 82. 180-82= 98

The picture below shows a container that Jeff uses to freeze water: A cylinder is shown with base diameter of 8 centimeters and
Butoxors [25]
Okay, first we need to figure out what one would make. We need to figure out the area of the base x height. The diameter is 8 so we will cut that to 4 so we can do piR2! 3.14x16 would be 50.24. Then we mutiply that by 10 to get 502.4cm3! Okay, now we would divide 2000/502.4 to find out how many times we would have to make the containers to get to 2000. The answer is 3.98, which we will have to round up since its asks for the minimum and you cant make a container 3.98 times. So the answer is 4!
