Answer: x >= -7

(x is greater than or equal to negative seven)

-23 - 10x < 47 is x > -7 (BUT WITH A LINE UNDER IT!!)

Explanation:
You have to add 23 to both sides making it 70. Then, when you divide or multiply with these inequalities you flip the sign. So when you divide a negative and a positive number, the answer is always negative. So 70 divided by -10 is -7

4 loads of stone weigh 2/3 ton. Find the weight of 1 load of stone.

Zina [86]

<span>For computing this, follow this method: 4 loads of stone weigh 2/3 ton. 4loads---------------------2/3 1load---------------------? So it will be computed as 1x 2/3 /4 = 2/3x4= 1/3x2=1/6 the weight of 1 load of stone is 1/6 ton Hope this helps. Let me know if you need additional help!</span>

PLEASE HURRY WILL GIVE BRAINLIEST if you show your work!

MAVERICK [17]

Answer:

(x² + 7x + 6) ÷ (x² + 2x + 1)

This should be in the form of a fraction, I just don't know how to format it that way on here.

Step-by-step explanation:

Since your denominators are equal on both fractions, you just need to subtract your numerators.

3x² + 9x + 12 - (2x² + 2x + 6)

When there is a - in front of an expression in parenthesis, you should change the sign of each term in the expression of the numerator being subtracted.

So this:

2x² + 2x + 6

Will become this:

2x² - 2x - 6

This is how it will look:

3x² + 9x + 12 - 2x² - 2x - 6

Now all you have to do is collect the like terms.

3x² and -2x² are like terms so you will add them together: 3x² + (-2x²) = 3x² - 2x² = x²

This is how your numerator should look so far:

x² + 9x + 12 - 2x - 6

Now we move on to the next like terms.

9x and -2x are like terms so we add them together: 9x + (-2x) = 9x - 2x = 7x

This is how your numerator should look so far:

x² + 7x + 12 - 6

Now we move on to the last set of like terms.

12 and -6 are like terms so we add them together: 12 + (-6) = 12 - 6 = 6

This is how your numerator should be now:

x² + 7x + 6

Now all you have to do is put your numerator on top of your denominator which is the same as in the start of your equation (x² + 2x + 1).

You are done! I hope this was clear and you understand :)

If the 3rd and 9th term of an ap are 4 and -8 respectively then which term of AP is zero

Anon25 [30]

Answer:

fifth term

Step-by-step explanation:

The n th term of an AP is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₃ = 4 and a₉ = - 8 , then

a₁ + 2d = 4 → (1)

a₁ + 8d = - 8 → (2)

Subtract (1) from (2)

6d = - 12 ( divide both sides by 6 )

d = - 2

Substitute d = - 2 into (1)

a₁ + 2(- 2) = 4

a₁ - 4 = 4 ( add 4 to both sides )

a₁ = 8

Thus equating the n th term formula to zero and solving for n

8 - 2(n - 1) = 0 ( subtract 8 from both sides )

- 2(n - 1) = - 8 ( divide both sides by - 2

n - 1 = 4 ( add 1 to both sides )

n = 5

The fifth term is equal to zero

{0,1,2,3,4,5,6,20,21,22,23,24,25} the distribution is considered to be: skewed the right, skewed the left, not skewed?

Katyanochek1 [597]

Answer:

Not skewed

Step-by-step explanation:

Since, the given distribution that is {0,1,2,3,4,5,6,20,21,22,23,24,25} has a mean = $\frac{0+1+2+3+4+5+6+20+21+22+23+24+25}{13}=\frac{156}{13}=12$ .

And the mode is the term which occurs frequently in the distribution, Since, in the given distribution, there is no term which is occurring frequently, therefore there is no mode for the given distribution, thus we cannot determine the skewness of the given distribution,

Hence the given distribution is not skewed.
