Answer:

$4.8x - 12 = 3.4x - 5 \\ 4.8x - 3.4x = 12 - 5 \\ 1.4x = 7 \\ \frac{1.4x}{1.4} = \frac{7}{1.4} \\ x = 5$

Answer:

x = 5

Step-by-step explanation:

Given

4.8x - 12 = 3.4x - 5 ( subtract 3.4x from both sides )

1.4x - 12 = - 5 ( add 12 to both sides )

1.4x = 7 ( divide both sides by 1.4 )

x = 5

Susie is paying $502.33 every month for her $150,000 mortgage payment. If this is a 4.5% 30 year mortgage, how much interest wil

Alchen [17]

You could find the interest paid by simply realizing that:

502.33(12)30-150000=total interest paid

i=502.33(12)30-150000

i=$30838.80

Find the output, y, when the input, 2, is -9. Y = Y < 8+ 4 1 -8 2 4 6 -6+

Luba_88 [7]

when x = -9, y = 1

Here, we want to get the value of y when x = -9

To find this, we look at the point x= -9 on the x-axis

After getting this, we trace it to the graph

Looking at the graph, the graph crosses the x-axis at exactly this point

What this mean is that the value of y at that point is 1

Hence, for input -9, output is 1

∵ The formula of the compound interest is

$A=P(1+\frac{r}{n})^{nt}$

→ A is the new amount

→ P in the initial amount

→ r is the interest rate in decimal

→ n is the number of periods

→ t is the time

∵ The initial amount is 800 dollars

∵ The annual rate is 3% = 3/100 = 0.03

∵ It is a compounded annually

∴ n = 1

∵ t = 5 years

→ Substitute all of these values in the formula above

$\begin{gathered} A=800(1+\frac{0.03}{1})^{1(5)} \\ A=800(1+0.03)^5 \end{gathered}$

→ Use the calculator to find the answer

∴ A = 927.4192594 dollars
