How can you identify a linear relationships in tables,graphs, and written form?

A linear function is one that has the form f(x) = ax + b. Here for each value of x there is only one corresponding value of f(x) and every value of f(x) is due to only one particular value of x. In other words there is a one to one correspondence between values of f(x) and values of x.

If the values of f(x) and x for a linear function are written in the form of a table we find that each value of f(x) has a corresponding value of x that is unique. If a graph is drawn of the function it is always a straight line.

A linear function results in a graph that is a straight line, and the values of f(x) and x written as a table show a one to one correspondence.

y = 2x + 15
x = 6 + 3y
y/2 = 3 − x

these are all linear anything with Y=mx+B

Which relation is a direct variation that contains the ordered pair (2, 7)? y = 4x – 1 y = StartFraction 7 Over x EndFraction y

Vanyuwa [196]

Answer:

The relation $y=\frac{7}{2}x$ or y = seven-halves x is a direct variation that contains the ordered pair (2,7).

Step-by-step explanation:

Given:

The ordered pair = (2, 7).

Now, to get the direct variation:

As (2,7) lies on it.

So, direct variation means $y=kx.$

$x=2.$

$y=7.$

Now,

$y=kx$

$7=k\times 2$

$\frac{7}{2} =k$

$k=\frac{7}{2}$

Now, to get the direct variation:

$y=kx$

$y=\frac{7}{2}x$

$y=\frac{7}{2}x$ or y = seven-halves x.

Therefore, the relation $y=\frac{7}{2}x$ or y = seven-halves x is a direct variation that contains the ordered pair (2,7).

Sarafina is making monthly payments into an annuity. She wants to have $800 in fund to buy a new convection range in three month

victus00 [196]

Answer:

$265.07

Step-by-step explanation:

The formula for the future value of an annuity is applicable.

A = P((1+r)^n-1)/r . . . . where r is the monthly interest rate and n is the number of months. P is the monthly payment, and A is the amount of the future value.

800 = P(1.006^3 -1)/(.006) = 3.018036P

P = 800/3.018036 ≈ 265.07

Sarafina's monthly payments need to be $265.07.

_____

This is about $1.60 less than the 266.67 she would deposit if she simply divided the desired balance by the number of months.

Because this number is rounded down, Sarafina will have a balance after 3 months of $799.99.
