Answer:

-1<x<1

Step-by-step explanation:

Subtract 1 on both sides:

-6x>-6

Divide -6 on both sides:

(since you are dividing by a negative you switch the sign)

x<1

subtract 4 on both sides:

3x>-3

Divide 3 on both sides:

x>-1

Thus -1<x<1

Hope this helps!

Which list of ordered pairs represents solutions to x + y = 2? (-4, 6), (0, 2), (4, 2); (-4, -6), (0, 2), (4, 2); (-4, 6), (0, 2

baherus [9]

Answer:

(-4, 6), (0, 2), (4, -2)

Step-by-step explanation:

x + y = 2?

(-4, 6), -4+6 = 2 True this is a solution

(0, 2), 0+2 = 2 True this is a solution

(4, 2); 4+2 = 6 False this is not a solution

This is not a solution set since we have a pair that is not a solution

(-4, -6), -4+-6 = 10 False this is not a solution. We do not have to check the rest since this cannot be a solution set

(0, 2),

(4, 2);

This is not a solution set since we have a pair that is not a solution

(-4, 6), -4 + 6 = 2 True this is a solution

(0, 2), 0 + 2 =2 True this is a solution

(4, -2) 4-2 =2 True this is a solution

This is a solution set since all the points are a solution

Differentiate with respect to x:y= sinh^-1(x^2+1)

Aleks [24]

Answer:

The first derivative of $y = \sinh^{-1} (x^{2}+1)$ is $y' = \frac{2\cdot x}{\sqrt{x^{2}+2\cdot x +2}}$ .

Step-by-step explanation:

We proceed to find the first derivative of $y = \sinh^{-1} (x^{2}+1)$ by explicit differentiation and rule of chain:

$y = \sinh^{-1} (x^{2}+1)$

$y' = \frac{2\cdot x}{\sqrt{(x^{2}+1)^{2}+1}}$

$y' = \frac{2\cdot x}{\sqrt{x^{2}+2\cdot x +2}}$

The first derivative of $y = \sinh^{-1} (x^{2}+1)$ is $y' = \frac{2\cdot x}{\sqrt{x^{2}+2\cdot x +2}}$ .

**I WILL GIVE BRAINLIST IF YOU ANSWER BOTH AS SIMPLE AS POSSIBLE**

maks197457 [2]

Answer:

The surface area of chest 2 would be 32 ft. The area of the base would be 6 ft

Step-by-step explanation:

If the shape is a square then multiplying the base by 6 would work but it is a rectangle in this case which means some sides are uneven. 4 sides are 6 ft and the other 2 are 4. So 6 x 4 plus 4 x 2 would equal 32
