Answer:

m = -4

Step-by-step explanation:

First, you should distribute -8 into m + 8 to get -8m - 64.  Then, you should combine -4m and -8m together to get -12m as a result.  Your equation should now be -24 - 2m = -12m - 64.  Add 12 on both sides to get -24 + 10m = -64.  Add 24 on both sides to get -40 on the right side.  Finally, divide 10 on both sides to get your m value which is -4.

Answer:

-4

Step-by-step explanation:

-24 - 2m = -4m - 8(m + 8) (Remove the parentheses)

-24 - 2m = -4m - 8m - 64 (Collect like terms)

-24 - 2m = -12m - 64 (Move the term)

-2m + 12m = -64 + 24 (Collect like terms, Calculate)

10m = -40 (Divide both sides)

m = -4

ANSWER ASAP!! WILL GIVE OR MORE POINTS TO THE FIRST ONE WHO ANSWERS!
Sergio [31]

Answer: See the picture attached.

Step-by-step explanation:

Given the following mixed numbers:

-2\frac{3}{4}\\\\-4\frac{1}{2}

You need to convert them to decimal numbers. The steps to do this are shown below:

1. Divide the numerator of the fraction by the denominator.

2. Add the quotient obtained to the whole number part.

Then:

-2\frac{3}{4}=-(2+0.75)=-(2.75)=-2.75\\\\-4\frac{1}{2}=-(4+0.5)=-(4.5)=-4.5

Therefore, the point is:

(-2.75,-4.5)

Where -2.75 is the x-coordinate and -4.5 is the y-coordinate.

Knowing this, you can plot it on the coordinate plane, as you can see in the picture attached.

John makes 35% of his free throw shots sue makes 40% of her free throw shot What is the possibility that John And sue both miss
Mandarinka [93]

Answer:

The possibility that John And sue both miss their shots = 0.39

Step-by-step explanation:

John makes 35% of his free throw shots = 0.35

The probability of John missing his shot = 0.65

Sue makes 40% of her free throw shot = 0.4

The probability of Sue missing his shot = 0.6

The possibility that John And sue both miss their shots = 0.65 (0.6)

= 0.39

Motion and rate of change derivatives. Attached is the question and where I am stuck, I would really appreciate the help :)
barxatty [35]

Answer:

A. 3 < t < 9

Step-by-step explanation:

When the particle is moving to the right, the velocity is positive.

To find the velocity, take the derivative of s(t) with respect to t.

s(t) = -t³/3 + 13t²/2 − 30t

s'(t) = -t² + 13t − 30

Find when the velocity is 0.

0 = -t² + 13t − 30

0 = t² − 13t + 30

0 = (t − 3) (t − 10)

t = 3, 10

Check the sign of s'(t) in each interval.

0 < t < 3, s'(t) < 0

3 < t < 9, s'(t) > 0

The particle moves to the right when 3 < t < 9.
