Which is the solution set of the compound inequality 3.5 x minus 10 greater-than negative 3 and 8 x minus 9 less-than 39

dexar [7]

The solution for the compound inequality is $x \in(2,6)$

Explanation:

The equations are $3.5x-10>-3$ and $8x-9$

To find the solution set for these compound inequalities, we need to solve the inequality.

First, we shall solve the inequality $3.5x-10>-3$

Adding both sides of the equation by 10, we have,

$3.5x>7$

Dividing both sides by 3.5, we get,

$x>2$

Now, we shall solve the inequality $8x-9$ ,

Adding both sides of the equation by 9, we have,

$8x$

Dividing both sides by 8, we get,

$x$

Thus, the solution set for the inequalities $3.5x-10>-3$ and $8x-9$ is $x \in(2,6)$

Which statement about y = x2 + 7x - 30 is true?

Lady_Fox [76]

Answer:

D. The zeros are 3 and -10, because y = (x - 3)(x + 10).

Step-by-step explanation:

$y=x^2+7x-30$

$0=x^2+7x-30$

$0=(x+10)(x-3)$

Therefore, D is correct by the Zero Product Property

How do I round 8164 to the 4 decimal point?

aalyn [17]

Yeah, I agree with letsgoplayd. Your answer doesn't make any sense because 8164 is not a decimal. But we can look at another example:

8164.45678

In this case, the number rounded to the 4th decimal point (ten thousandths) would be

8164.45680

Because the digit after the 7 is 8, we should round the "78" part to "80".

These two rules will help:

5 or more, raise the score (add 1 to the digit, and let the digit directly behind it become 0.)

4 or less, let it rest (keep the digit, and let the digit directly behind it turn to a 0.)

Hope this helps! :)

Find the missing measures for the rectangle. l = _?_ w = 4.2 m A = 37.8 m2 P = _?_ A) 9 m; 26.4 m B) 14.7 m; 61.74 m C) 9 m; 13.

egoroff_w [7]

Answer:

The correct answer is A.

Step-by-step explanation:

The area of a rectangle can be calculated using the following formula:

$Ar=W . I$

If we know that the area measures $37.8 m^{2}$ and one side of the figure measures 4.2 m, we can say that:

$37.8m^{2}=4.2m. I$

We isolate the side we don't know:

$\frac{37.8m^{2}}{4.2m} = I\\9 m = I$

So I = 9 m

To know the perimter of a rectangle, we use the following formula:

$P= I. 2 + W . 2$

$P= 9m. 2 + 4.2m. 2$

$P= 26.4 m$
