Answer:

f(x) = 2(1/3)^x

Step-by-step explanation:

To find the parameters of this exponential equation, follow the instructions given in the hint.

b = 6/18 = 1/3 . . . . . divide 6 by 18 to find 'b'

18 = a(1/3)^-2 . . . . . substitute a point and 'b' in the equation

18(1/3)^2 = a = 2 . . . . multiply by (1/3)^2

The equation is ...

f(x) = ab^x

f(x) = 2(1/3)^x

What is the solution of 5/2-7= 3/4x+14,

Sidana [21]

Answer:

D) x = 12

Step-by-step explanation:

Given:

$\sf{\dfrac{5}{2}x-7=\dfrac{3}{4}x+14 \implies \dfrac{10}{4}x-7=\dfrac{3}{4}x+14}$

1. Multiply both sides by 4

$\sf{4\left(\dfrac{10}{4}x-7\right)=4\left(\dfrac{3}{4}x+14\right)}\\\\\implies 10x-28=3x+56$

2. Subtract 3x from both sides

$\sf{10x-3x-28=3x-3x+56}\\\\\implies 7x-28=56$

3. Add 28 to both sides

$\sf{7x-28+28=56+28}\\\\\implies 7x=84$

4. Divide both sides by 7 to isolate the variable:

$\sf{\dfrac{7x}{7}=\dfrac{84}{7}}\\\\\implies x=12$

Ludmilka [50]

Answer:

75% chance

Step-by-step explanation:

Probability always adds to 1.00

Letter grades are always in the form A, B, C, D...

The grades above a C are A, which is a 25% chance and B, which has a 50% chance. Adding these up we get a 75% chance.
