Answer:

C

Step-by-step explanation:

What is x if 3x+2=5x-8?
anyanavicka [17]
3x + 2 = 5x - 8
Flip
5x - 8 = 3x + 2
Subtract both sides by 3x
2x - 8 = 2
Add both sides by 8
2x = 10
Divide both sides by 2
x = 5

That's your answer.

Have an awesome day! :)

Novay_Z [31]

Answer:

  • Annabella will save $4950.11 after 2 years.

Step-by-step explanation:

<h3>Given</h3>

  • Periodic payment P = $200,
  • Period t = 2 years,
  • Number of compounds, monthly n = 12,
  • Interest rate, r = 3.2% = 0.032.

<h3>To find</h3>

  • Future value of saving, F

<h3>Solution</h3>

Use periodic compound formula:

F=P\cfrac{(1+r/n)^{nt}-1}{r/n}

Substitute the values and calculate:

F=200\cfrac{(1+0.032/12)^{12*2}-1}{0.032/12} =4950.12     rounded

Graph the equation F(x)=(1/3)^x
scoray [572]

The value of a=9,b=3 and c=1

Step-by-step explanation:

The graph shown is for function f(x)

The given function is f(x)=(\frac{1}{3}) ^{x}

Table says,

X      Y

-2      a

1        b

0       c

1     (1/3)

2    (1/9)

To find value of a:

From table, for output value a, input value, x=(-2)

we can write f(-2)=a

Therefore,

f(x)=(\frac{1}{3}) ^{x}

f(-2)=(\frac{1}{3}) ^{(-2)}

a=(\frac{1}{3^{(-2)}})

a=3^{(2)}

a=9

To find value of b:

From table, for output value a, input value, x=(-1)

we can write f(-1)=b

Therefore,

f(x)=(\frac{1}{3}) ^{x}

f(-1)=(\frac{1}{3}) ^{(-1)}

b=(\frac{1}{3^{(-1)}})

b=3^{(1)}

b=3

To find value of c:

From table, for output value a, input value, x=(0)

we can write f(0)=c

Therefore,

f(x)=(\frac{1}{3}) ^{x}

f(0)=(\frac{1}{3}) ^{(0)}

c=(\frac{1}{3^{(0)}})

c=1
