Select 2 of the following

siniylev [52]

Answer:

OPTION C: The ratio is a constant.

OPTION E: The ratio is equal to b.

Step-by-step explanation:

Given: $f(x) = a.b^x$

The ratio of f(x + 1) and f(x) = $\frac{f(x + 1)}{f(x)} = \frac{a.b^{x + 1}}{a.b^x}$

Since, $a^{x + 1} = a^x. a$

$\implies \frac{f(x + 1)}{f(x)} = \frac{a.b^x.b}{a.b^x}$

Cancelling out $a.b^x$ we get:

$\frac{f(x + 1)}{f(x)} = b$

This shows that the ratio is always a constant and that constant is equal to b.

Write each equation in slope-intercept form.

Alexxx [7]

Answer:

A. y = -3/2x + 1

B. y = -5/3x + 10

C. y = -x + 6/5

Step-by-step explanation:

A. You just have to isolate the y so divide by 4: y = -3/2x + 1

B. 3y = -5x + 30

Divide by 3: y = -5/3x + 10

C. -5x + 6 = 5y

Divide by 5: -1x + 6/5 = y OR y = -x + 6/5

Write an equation of the circle with center (4,5) and radius 9.

mixer [17]

Answer:

I'm going to write both of these because maybe you have a fill in the blank question. I don't know.

$(x-4)^2+(y-5)^2=9^2$

Simplify:

$(x-4)^2+(y-5)^2=81$

Step-by-step explanation:

$(x-h)^2+(y-k)^2=r^2$ is the equation of a circle with center (h,k) and radius r.

You are given (h,k)=(4,5) because that is the center.

You are given r=9 because it says radius 9.

Let's plug this in.

$(x-4)^2+(y-5)^2=9^2$

Simplify:

$(x-4)^2+(y-5)^2=81$
