Which of the following describes how to graph the line whose equation is y = x - 1?

1 answer:

7 0

You would need to substitute a number for y. I would probably put 0 for y which would then give you x.

y = 0

x = 1

Then you can easily graph the point. :)

The graph of a linear function passes through the points (2, 4) and (8, 10).

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\

% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies

Is parallelogram a rectangle

denis-greek [22]

Answer:

Sometimes, but not always.

Step-by-step explanation:

A parallelogram is a quadrilateral with two pairs of parallel sides, but there are no requirements for its interior angles. A rectangle, on the other hand, <em>must</em> have four interior 90 degree angles. So a rectangle is always a parallelogram, but a parallelogram is not always a rectangle.

If $64,000 is invested in an IRA account with an annual interest rate of 8% compounded once a year, what is the value of the acc

Iteru [2.4K]

Answer: the value of the account after 6 years is $101559.96

Step-by-step explanation:

If $64,000 is invested in an IRA account, then

Principal = $64,000

So P = 64,000

The rate at which $64000 was compounded is 8%

So r = 8/100 = 0.08

If it is compounded once in a year, this means that it is compounded annually (and not semi annually, quarterly or others). So

n = 1

We want to determine the value of the account after 6 years, this means

time, t = 6

Applying the compound interest formula,

A = P(1 + r/n)^nt

A = amount after n number of years

A = 64000( 1 + 0.08/1)^1×6

A = 64000(1.08)^6

A= 64000×1.58687432294

A= 101559.956668416

Approximately $101559.96 to 2 decimal places
