What is the slope of the line that passes through the pair of points (3, -1) and (5, -8)

Mathematics

The two points are (x1,y1) = (3,-1) and (x2,y2) = (5,-8)

Plug those coordinates into the slope formula below.

m = (y2-y1)/(x2-x1)

m = (-8 - (-1))/(5 - 3)

m = (-8 + 1)/(5 - 3)

m = -7/2

<h3>Answer: The slope is -7/2</h3>

note: the fraction -7/2 converts to the decimal form -3.5

You deposit $975.52 in a bank account. Find the balance after 4 years if the account pays 7.25% annual interest compounded quart
sladkih [1.3K]

Answer:

The final ballance will be $1300.37.

Step-by-step explanation:

In this case we have a compounded interest, in order to calculate the final balance we need to use the following formula:

S = P(1 + r/n)^(n*t)

Where S is the final balance, P is the initial investment, r is the rate of interest, t is the time and n is the rate at which it is compounded. Since we have all the values we can directly apply to the formula as follows:

S = 975.52*(1 + 0.0725/4)^(4*4)

S = 975.52*(1.018125)^(16)

S = 975.52*1.333

S = 1300.37

The final ballance will be $1300.37.

Triangle PQR has vertices P(–2, 6), Q(–8, 4), and R(1, –2). It is translated according to the rule (x, y) → (x – 2, y – 16).
Amanda [17]
Since you subtract 16 from the y value, P is (-2, 6), and the y value comes second (meaning that it's 6), we get 6-16=-10
