Does anyone know a rule that work for all of these

Divide each term in the y column by 2 to go from this list {8, 2, 0, 2, 8} to this list {4, 1, 0, 1, 4}

This list {4, 1, 0, 1, 4} is a bunch of perfect squares so it suggests that y = x^2

However we must double the values to get back to the original list. So the rule is y = 2*x^2

Answer:

$w\geq -2$

Step-by-step explanation:

Distribute the 5 into the parentheses (multiply them both by 5)

$15.5w+6.5\geq -25$

Subtract the 6.5 from -25.

$15.5w\geq -31.5$

Divide -31.5 by 15.5.

$w\geq -2$

What is the inverse of the function f(x) = x + 2?

wolverine [178]

Turn f(x) into y so the equation is y=x+2. Now switch their places so it is x=y+2. Now solve for y. The answer is y=x-2.

Solve for x to the nearest degree (34.3 = 34)

Hoochie [10]

Answer:

48°

Step-by-step explanation:

We can solve this using our knowledge on tangents of an angle. Remember, tangents are the opposite leg divided by the leg adjacent to that angle.

This means the tangent of x° = $\frac{10}{9}$ . Now that we know the tangent ratio, we can find the angle with inverse trigonometric ratios. These kinds of ratios give us the opposite of the tangent - which would lead to the angle measure we're looking for. The equation would look like this:

$x = arctan (\frac{10}{9})$

Using a calculator, the answer would be:

$x = 48.0128$

Rounding this to the nearest degree would give us 48° as our answer! I hope this was clear enough.
