Answer:

"I Only" is the correct answer

Step-by-step explanation:

Given inequality is:

-10>3x-6

In order to check which numbers are solution to the given inequality, we will put each number one by one in the inequality. If the inequality is true after putting the number, the number is the solution of the inequality.

So,

I . -10

Putting -10 in the inequality

$-10>3x-6\\-10>3(-10)-6\\-10>-30-6\\-10> -36$

The inequality results in true after putting x=-10 so -10 is the solution of inequality.

II. 5

Putting 5 in the inequality

$-10>3x-6\\-10>3(5)-6\\-10>15-6\\-10>9$

The equality doesn't hold true for x=5 so 5 is not the solution of the problem.

III. -1

Putting -1 in the equation

$-10>3x-6\\-10>3(-1)-6\\-10>-3-6\\-10>-9$

Inequality doesn't hold true for x=-1 so it is not the solution of the inequality.

Hence,

"I Only" is the correct answer as only -10 is the solution of inequality.

I need help working this algebra 2 question 3/4 - 5/6R = 7/10

Brilliant_brown [7]

Answer:

R = 3/50

Step-by-step explanation:

If you are trying to solve for a variable,

1. Simplify both sides of the equation:

3/4 - 5/6R = 7/10 will now be (-5/6r) + 3/4 = 7/10

2. Add -3/4 from both sides of the equation:

(-3/4) + 3/4 = 0 and (-3/4) - 7/10 = -1/20.

You will be left with: -5/6r = -1/20.

3. Divide both sides by (-5/6).

(-5/6r) / -5/6 = 1R or just R. (-1/20) / -5/6 = 3/50

You are left with the answer:

R = 3/50

I hope this helps!

What is the cube root of 216x^9y^18?

PilotLPTM [1.2K]

Answer:

The cube root of given expression is $6x^3y^6$ .

Step-by-step explanation:

The given expression is

$\sqrt[3]{216x^9y^{18}}$

It can be written as

Use the exponent property: $a^{mn}=(a^m)^n$

$\sqrt[3]{216x^9y^{18}}=\sqrt[3]{6^3(x^3)^3(y^6)^{3}}$

$\sqrt[3]{216x^9y^{18}}=\sqrt[3]{(6x^3y^6)^{3}}$

$\sqrt[3]{216x^9y^{18}}=6x^3y^6$

Therefore the cube root of given expression is $6x^3y^6$ .

Which of the equations below could be the equation of this parabola?

Mademuasel [1]

Answer:

Option B: $y = -\frac{1}{2} x^2$

Step-by-step explanation:

The parabola has its concavity downwards, so we need a function in the model:

$y = ax^2 + bx + c$

With a negative value of 'a'

The vertex is (0,0), so we have that:

$0 = 0a + 0b + c$

$c = 0$

The x-coordinate of the vertex is given by the equation:

$x\_vertex = -b/2a$

$-b/2a = 0$

$b = 0$

So we have a function in the model:

$y = ax^2$

With a < 0

The only option with this format is B:

$y = -\frac{1}{2} x^2$

Consider a graph of the equation y = x + 6. What is the y-intercept?

Ratling [72]

In y = mx + b form, which is what ur equation is in, the y int can be found in the b position

y = mx + b
y = x + 6

as u can see, the number in the b position, ur y int, is 6 <==
