y > 5x-1, because it is just a greater than sign, the shaded area would be to the left of a dotted line.

y ≤ x +3, because the sign is less than or equal to, the line is solid and the shaded area would be to the right.

Combine the shaded areas would make Graph B. the correct answer.

Write an exponential function in the form y=ab^x that goes through points (0,9) and (3, 576)

sineoko [7]

Answer:

An exponential function in the form y=9(4ˣ)

Step-by-step explanation:

Step(i):-

Given that exponential function

y = a bˣ ...(i)

The equation (i) passes through the point (0,9)

9 = a (b )⁰ = a

a =9

Step(ii):-

The equation (i) passes through the point (3,576)

576 = 9(b)³

⇒ $\frac{576}{9} = b^{3}$

⇒ 64 = b³

⇒ 4³ = b³

$(4^{3} )^{\frac{1}{3} } = (b^{3} )^{\frac{1}{3} }$

b = 4

Final answer:-

An exponential function in the form y=abˣ

An exponential function in the form y=9(4ˣ)

What are the Slope and Y-intercept of y>-2x+3

Pepsi [2]

Answer:

The y-intercept would be y > 3

The slope would be -2

Step-by-step explanation:

Slope is very simple to find, as it is just the value next to x.

The y-intercept would be 3 as it is outside the ax.

Evaluate each expression when x=3 (iready)

Mkey [24]

Answer:

Step-by-step explanation:

x^5 = ?^5

x = 3

We plug in x = 3:

3^5 = ?^5

We find the fifth root of both sides and get:

3 = ?

That means that 3 is the answer
