Answer:

C. 2

Step-by-step explanation:

[tex]\frac{-8(17-12)}{-2(8-(-2))}[/tex]

Subtract inside the parenthesis inside the numerator.

[tex]\frac{-8(5)}{-2(8-(-2))}[/tex]

Multiply -8 and 5 in the numerator.

[tex]\frac{-40}{-2(8-(-2))}[/tex]

Rewrite the denominator knowing that x - (-y) = x + y.

[tex]\frac{-40}{-2(8+2)}[/tex]

Add inside the parenthesis in the denominator.

[tex]\frac{-40}{-2(10)}[/tex]

Multiply -2 and 10 in the denominator.

[tex]\frac{-40}{-20}[/tex]

Rewrite the fraction knowing that (-x)/(-y) = x/y.

[tex]\frac{40}{20}[/tex]

Divide 40 by 20 to get: 2.

Answer:

Step-by-step explanation:

Substitute the given points (x, y )

For (x= 1, y= -4)

     4x−5y = 24

4*1 −5* -4 = 24

    4 + 20 = 24

          24 = 24 ✅

For (x= 4, y= 8)

     4x−5y = 24

 4*4 −5*8 = 24

     16 -40 = 24

         -24 = 24 ❌

For (x= 6, y= 0)

     4x−5y = 24

4*6 −5* 0 = 24

       24 -0 = 24

          24 = 24 ✅

For (x= -9, y= -12)

       4x−5y = 24

4*-9 −5*-12 = 24

    -36 + 60 = 24

              24 = 24 ✅

Answer:

5 89/100

Step-by-step explanation:

If there is a negative sign in the denominator of any of the fractions, shift the negative sign(s) to the numerator:

-5/6=5/6

Division of fractions is equivalent to multiplication by the reciprocal of the second fraction:

5/6÷1/6=5/6×6/1

Once rearranged, multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:

(5 × 6) / (6 × 1) =30 / 6

The Greatest Common Factor (GCF) of 30 and 6 is 6. The result can be simplified by dividing both the numerator and denominator by 6.

30/6= (30 ÷ 6) / (6 ÷ 6) = 5

therefore..

-5/6÷1/6= 5

qns

8/9 + {(-5/6) / (1/6)} = 8/9 + 5 = 5 8/9

Combine the whole numbers and fractions together:

(0 + 5) + (8/9+0)

The whole numbers part is:

0 + 5 = 5

For the fractions part:

The Least Common Multiple (LCM) of 9 and 1 is 9. Multiply the numerator and denominator of each fraction by whatever value will result in the denominator of each fraction being equal to the LCM:

8/9+0=8/9+0 × 9=8/9+0/9

Now that the fractions have like denominators, add the numerators:

8/9+0/9=(8+0)/9=8/9

Put the whole number and fraction together:

5 +8/9=5 8/9

The result is:

8/9+5=5 8/9

Answer:

y=-4

Step-by-step explanation:

Distribute:

−2+12+14=9

Add the Numbers:

12+12=9

Rearange the Terms:

12+12=9

Subtract 12 from both sides:

12+12−12=9−12

12=9−12

Subtract 9y from both sides:

12−9=9−12−9

3=−12

Divide both sides of the equation by the same term:

3y/3=12/3

HOPE THIS HELPS

Answer:

The average speed here is 60 mph.

Step-by-step explanation:

We need to express the unit rate here.  That's the speed, which is defined as (distance) / (time):

                       1 mile

speed s(t) = ----------------

                       t (min)

We need to convert the unit of time (min) to the new unit of time (hrs):

                       1 mile           60 min

speed s(t) = --------------- * -------------- = 60 miles/hr = 60 mph

                       t (min)             1 hr

The average speed here is 60 mph.  This is not dependent on time, t, so we cannot calculate s(10) or s(12).  Because of this, s(t) = 60 mph.  The distance traveled in t hours is d(t) = s(t)*t.

Answer:

  x = 0, 1/3

Step-by-step explanation:

The greatest common factor is 2x. Factoring that out, we have ...

  2x(3x -1) = 0

The solutions will be the values of x that make the factors 0.

  x = 0

  3x -1 = 0   ⇒   x = 1/3

The solutions are x = 0, 1/3.

_____

Check

x = 0   ⇒   6·0² -2·0 = 0   ⇒   0 - 0 = 0 . . . true

x = 1/3   ⇒   6(1/3)² -2(1/3) = 0   ⇒   6/9 -2/3 = 0 . . . true

So you would multiply the frequency to the score because finding the average is adding everything. then you add those numbers up. then, add up the frequency to get your divisor. After you divide you take your number and round to the hundreth or tenth
