Answer:

The third and fourth one

Step-by-step explanation:

Hii,

When you divide by a negative, the sign flips. In the third and fourth one you're dividing by a negative so the inequality sign flips. For the rest, you're not.

Hope this helps :)

What number fills in the blank to complete the factorization of 3x + 24? (x + 8)

Crank

we have

$3x+24$

Find the greatest common factor GCF

we know that

$3\\ Factors=1,3\\ \\ 24=2^{3}*3\\ Factors=1,2,3,4,6,8,12,24$

The GCF is equal to $3$

therefore

$3x+24=3*(x+8)$

the answer is

The number is $3$

Find the point where the graph of -2x+2y=4 crosses the y-axis?

topjm [15]

When graph crosses y-axis, x=0

-2x+2y=4
-2*0+2y=4
2y=4
y=2

x=0, y=2,
so point is (0,2).

Which is better: having a stock that goes up 30% on Wednesday than drops 20% on Thursday, or a stock

finlep [7]

Step-by-step explanation:

If the stock goes up 30%, it's multiplied by $1.3$ .

The reason is that $x + .3 \times x=1.3\times x$

If the stock goes down 20%, it's multiplied by $0.8$

The reason is that $x - .2 \times x = 0.8 \times x$

If the stock goes down 30%, it's multiplied by $0.7$

The reason is that $x - .3 \times x = 0.7 \times x$

If the stock goes up 40%, it's multiplied by $1.4$ .

The reason is that $x + .4 \times x=1.4\times x$

If you increase it by 30% and then drop it by 20%, it means you are multiplying it by $1.3$ and then multiplying it by $.8$ . In other words:

$1.3 \times 0.8=1.04$

So, the net gain is = .04

Assume the original value = 500

Increase it by 30% and it becomes 650

Decrease 650 by 20% and it becomes 520

So, the net gain = 20

Verification:

$500 \times .04=20$

And

If you drop it by 30% and then increase it by 40%, you are multiplying it by .7 and then multiplying it by 1.4. In other words:

$.7 \times 1.4=0.98$

So, the net loss is = 1 - 0.98 = .02

Assume the original value = 500

Decrease it by 30% and it becomes 350.

increase 350 by 40% and it becomes 490.

So, the net loss is = 10

Verification:

$500 \times .02=10$
