Which phrase describes the linear relationship between the x and y values shown in the table?

kompoz [17]

9514 1404 393

Answer:

C. y is 6 less than x

Step-by-step explanation:

It is not hard to check.

A. 6 times x is 6×8 = 48, not 2

B. 6 times y is 6×2 = 12, not 8

C. 6 less than 8 is 2; 6 less than 9 is 3

D. 6 more than 8 is 14, not 2

The relation described in C matches the table.

The right expression to calculate how much money will be in an investment account 14 years from now if you deposit $5,000 now an

Svet_ta [14]

Answer:

The expression to compute the amount in the investment account after 14 years is: <em>FV</em> = [5000 ×(1.10)¹⁴] + [3000 ×(1.10)⁸].

Step-by-step explanation:

The formula to compute the future value is:

$FV=PV[1+\frac{r}{100}]^{n}$

PV = Present value

r = interest rate

n = number of periods.

It is provided that $5,000 were deposited now and $3,000 deposited after 6 years at 10% compound interest. The amount of time the money is invested for is 14 years.

The expression to compute the amount in the investment account after 14 years is,

$FV=5000[1+\frac{10}{100}]^{14}+3000[1+\frac{10}{100}]^{14-6}\\FV=5000[1+0.10]^{14}+3000[1+0.10]^{8}$

The future value is:

$FV=5000[1+0.10]^{14}+3000[1+0.10]^{8}\\=18987.50+6430.77\\=25418.27$

Thus, the expression to compute the amount in the investment account after 14 years is: <em>FV</em> = [5000 ×(1.10)¹⁴] + [3000 ×(1.10)⁸].

Can someone please help☹️❤️

Answer:

Slope = 2 y - intercept = ( 0 , -2 ) equation: y = 2x - 2

Step-by-step explanation:

We can begin solving by first understanding what slope is.

Slope is the rate of change in a line.

The formula for slope is:

(For any two points on a line)

m = y₁ - y₂ / x₁ - x₂

**m is the variable for slope

Two points on the line are: ( 6, 10 ) and ( 2, 2 )

Here is where we'll plug in the formula:

m = 10 - 2 / 6 - 2

m = 8 / 4

m = 2

Now that we have our slope, we only have to look at the graph to find the y-intercept.

The y-intercept is the point on the graph crosses the y-axis (this effectively means that the x value will always be 0)

When we look at the graph, we can see that the y-intercept is: ( 0, -2 )

All that's left is to right the equation in slope-intercept form.

The equation is arranged just as it says in the name:

y = mx + b

(m = slope b = y -intercept)

When we plug in our variables, the equation becomes:

y = 2x - 2
