Answer:

2/9^8

Step-by-step explanation:

3^0 = 1 so it turns into 9^-8/ 2^-1

Then put 9^-8 on the bottom to make it positive

Now its 1/9^8 & 2^-1

Then put 2 on top to make it positive and 2^1 is just 2

So now you have 2/9^8

What is the coefficient of (3y^2 + 9)5
PtichkaEL [24]

The coefficient of (3y² + 9)5 is <u>15</u>.

A polynomial is of the form a₀xⁿ + a₁xⁿ⁻¹ + a₂xⁿ⁻² + ... + aₙ₋₁x + aₙ.

Here, x is the variable, aₙ is the constant term, and a₀, a₁, a₂, ..., and aₙ₋₁, are the coefficients.

a₀ is the leading coefficient.

In the question, we are asked to identify the coefficient of (3y² + 9)5.

First, we expand the given expression:

(3y² + 9)5

= 15y² + 45.

Comparing this to the standard form of a polynomial, a₀xⁿ + a₁xⁿ⁻¹ + a₂xⁿ⁻² + ... + aₙ₋₁x + aₙ, we can say that y is the variable, 15 is the coefficient, and 45 is the constant term.

Thus, the coefficient of (3y² + 9)5 is <u>15</u>.

Find the slope.<br> Find the slope
creativ13 [48]

Answer:

m=-2

Step-by-step explanation:

The two given points are: (-3, -2) and (-2, -4)

The equation for slope is m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{(-4)-(-2)}{(-2)-(-3)}

m=-2/1

m=-2
