Can someone help please

Mathematics
1 answer:
faltersainse [42]3 years ago
5 0

Answer:

9>x>-3

Step-by-step explanation:

1) first lets write 2 inequalities:

9>x  and -3<x

remember -3 is less than x is the same as x is greater than -3

so I can write -3<x as

x>-3

so 9 is greater than "x" and "x" is greater than -3.....Is there any way we can combine these inequalities?

fortunately, there is a way! combing 2 inequalities as one is called a compound inequality

so 9 is greater than x:

9>x

and x is greater than -3

9>x>-3

boom!

Hope this helps!

(to solve the inequality just take the compound inequality as two seperate inequalities)

The slope of the line below is 0.8. Write the equation of the line in point-slope
AlexFokin [52]

The equation of the line is y = 0.8x - 1.4 if the  slope of the line is 0.8 and line passes through coordinates (-2,-3)

<h3>What is a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

\rm m =\dfrac{y_2-y_1}{x_2-x_1}

The slope m = 0.8

The line passing through coordinates (-2,-3)

y = mx + c

y = 0.8x + c

Plug the point in the equation.

-3 = 0.8(-2) + c

c = -1.4

y = 0.8x - 1.4

Thus, the equation of the line is y = 0.8x - 1.4 if the  slope of the line is 0.8 and line passes through coordinates (-2,-3)

Solve (16×^3-3×^2+43×-5)÷(×^2-2)
Oksana_A [137]

Answer:

3872/(x^2 - 2)

Step-by-step explanation:

Simplify the following:

(16^3 - 3^2 - 5×43)/(x^2 - 2)

3^2 = 9:

(16^3 - 9 - 5×43)/(x^2 - 2)

16^3 = 16×16^2:

(16×16^2 - 9 - 5×43)/(x^2 - 2)

| 1 | 6

× | 1 | 6

| 9 | 6

1 | 6 | 0

2 | 5 | 6:

(16×256 - 9 - 5×43)/(x^2 - 2)

16×256 = 4096:

(4096 - 9 - 5×43)/(x^2 - 2)

43 (-5) = -215:

(4096 - 9 + -215)/(x^2 - 2)

4096 - 9 - 215 = 3872:

Answer: 3872/(x^2 - 2)
