Answer:

Tn = 7 + (n - 1)*(6)

Step-by-step explanation:

The explicit rule is in the form: Tn = a + (n - 1)*(d), where 'a' is the first term and d is the common difference.

The first term in the sequence is 7, so 'a' is 7. The common difference is 6

(13 - 7) = 6, hence 'd' is 6.

Therefore, Tn = 7 + (n - 1)*(6)

The value of a collector’s item is expected to increase exponentially each year. The item is purchased for $500. After 2 years,

Andreyy89

Y = 500(1 + r)^x; where r is the rate and x is the number of years.
500(1 + r)^2 = 551.25
(1 + r)^2 = 551.25/500 = 1.1025
1 + r = sqrt(1.1025) = 1.05

Therefore, the equation that represents y, the value of the item after x years is
y = 500(1.05)^x

Answer:

a = 2

Step-by-step explanation:

We can use cross products to solve

8 a

----- = -------

28 7

8*7 = 28*a

Divide each side by 28

56/28 = 28a/28

2 =a

Please help Fr pleased I’m begging you

Answer:

y = $\frac{3}{8}$ x - 2

Step-by-step explanation:

<u>The answer to this problem is a simple plug-in of the given values into the slope-intercept formula.</u>

Slope intercept formula: y = mx + b

(m = slope)

(b = y intercept)

If the equation has a slope of m = $\frac{3}{8}$ , then the slope-intercept form would be:

y = $\frac{3}{8}$ x

If the y-intercept of an equation is (0 , -2), then the slope intercept form would be:

y = mx - 2

<u>Putting both of these values into an equation would give option A:</u>

y = $\frac{3}{8}$ x - 2
