Answer:

6

Step-by-step explanation:

Given

\frac{8}{-4} /  \frac{-3}{9}

Required

Solve

\frac{8}{-4} /  \frac{-3}{9}

We start by converting the division sign to multiplication

\frac{8}{-4} /  \frac{-3}{9} =\frac{8}{-4} *  \frac{-9}{3}

Then, we divide -9 by 3

\frac{8}{-4} /  \frac{-3}{9}=\frac{8}{-4} *  -3

Then, we divide 8 by -4

\frac{8}{-4} /  \frac{-3}{9}=-2 *  -3

Multiply -2 and -3 to give final result

\frac{8}{-4} /  \frac{-3}{9} = 6

Hence, \frac{8}{-4} /  \frac{-3}{9} is equivalent to 6

Which of the following statements is NOT true about the graph of a system of
Trava [24]

Answer:

The lines will have one positive y-intercept and one negative y-intercept is NOT true.

Step-by-step explanation:

If a graphed system has infinitely many solutions, that means that the two equations are the exact same. This means that they'll have the same slope, y-intercept, and will share all of the same points. Answer b is the only choice left.

Pls Someone help me I don't understand math very well can someone help me on how to get the answer for 1/4 x 8 4/9?
Eduardwww [97]

Answer:

2 4/36

Step-by-step explanation:

To do this, multiply the whole number by the denominator and add it to the numerator.

8 x 9 = 72

72 + 4 = 76

76/9

<em>Then multiply across (multiply numerators with numerators; denominators with denominators)</em>

76 x 1 = 76

9 x 4 = 36

76/36 = 2  4/36

____________________________

<em>A faster way to do this is to multiply the whole number by the fraction and then the fraction by the fraction.</em>

1/4 x 8/1 = 8/4 = 2

1/4 x 4/9 = 4/36

 = 2  4/36

The tables below show four sets of data:
vovangra [49]

Answer:

Hence, the set that represent a negative linear association between x and y is:

Set A.

Step-by-step explanation:

We are given 4 sets of data as:

<u>Set A  </u>

x 1 2 3 4 5 6 7 8 9  

y 10 9 8 7 6 5 4 3 2

<u>Set B  </u>

x 1 2 3 4 5 6 7 8 9  

y 3 4 5 6 7 8 9 10 11

<u>Set C  </u>

x 1 2 3 4 5 6 7 8 9  

y 8 6 5 4 3.5 3 2.5 2 2

<u>Set D  </u>

x 1 2 3 4 5 6 7 8 9  

y 1 2.5 2.5 3 4 5 6 8 9

We are asked to determine the set which represent negative linear association between x and y?

  • Clearly in Set B and Set D the values of y keeps on increasing as the value of x increases; hence they both represent a positive linear association between x and y.
  • In set C the relationship is non-linear though it is negative.
  • Clearly in Set A we could see that the the y is related to x as:

         y=11-x or y= -x+11.

Hence, clearly we could see that the relationship is linear and also negative as the value of y keeps on decreasing with increasing x.

Hence, the set that represent a negative linear association between x and y is:

Set A.
