-4(1-x)\leq-12+2x\qquad\text{use distributive property}\n\n(-4)(1)+(-4)(-x)\leq-12+2x\n\n-4+4x\leq-12+2x\qquad\text{add 4 to both sides}\n\n4x\leq-8+2x\qquad\text{subtract 2x from both sides}\n\n2x\leq-8\qquad\text{divide both sides by 2}\n\n\boxed{x\leq-4}

Does 4/8 +7/8=11/16 or 11/8

Answers

that's easy it is 11/8 because 4+7=11 8 will be the same
The answer would be 11/8 because 7+4=11 and then the denominator(8) will stay the same.

Cot^2x csc^2x + 2 csc^2x –cot^2 = 2

Answers

Answer:

x = π/2 + πk

Step-by-step explanation:

cot² x csc² x + 2 csc² x − cot² x = 2

Multiply both sides by sin² x:

cot² x + 2 − cos² x = 2 sin² x

Add cos² x to both sides:

cot² x + 2 = 2 sin² x + cos² x

Pythagorean identity:

cot² x + 2 = sin² x + 1

Subtract 1 from both sides:

cot² x + 1 = sin² x

Pythagorean identity:

csc² x = sin² x

Multiply both sides by sin² x:

1 = sin⁴ x

Take the fourth root:

sin x = ±1

Solve for x:

x = π/2 + 2πk, 3π/2 + 2πk

Which simplifies to:

x = π/2 + πk

What does g equal if the equation is 76=g2nd power

Answers

\sf76=g^2

Find the square root of both sides:

\sf~g=√(76)

\sf~g\approx8.72

If 76 is 'g to the second power', then 'g' is the square root of 76.

Every positive number has two square roots.

The square roots of 76 are irrational numbers ... they can't be written exactly
with just digits.   When they're rounded to a reasonable number of decimal
places, they are ...

        g = + 8.7178
and
        g = - 8.7178 .
