What does f(-1) =_ and x=_ ?

Mathematics
1 answer:
lubasha [3.4K]3 years ago
5 0

Answer:

F(-1) = 1

x = 3

Step-by-step explanation:

1) Assume that f(-1) = y1

So that point A (x1 = -1; y1) is a point lying in the graph representing the equation y = f(x)

As it can be seen in the figure, the graph representing that equation crosses point (-1; 1)

=> Point A has y1 = 1

=> f (-1) =1

2) Assume that f(x2) = -2

So that point B (x2; y2 = -2) is a point on the graphy representing the equation y = f(x)

As indicated in the figure, the graph crosses point (3; -2)

=> Point B has x2 = 3

=> When f(x) = -2, x = 3

Catherine invested a principal of $1,650 in her bank account with interest rate 3.1 % How much interest did she earn in 14 years
never [62]

Answer:

$693

Step-by-step explanation:

Catherine invested a principal of $1,650 in her bank account with;

interest rate of 3.1%

How much interest did she earn in 14 years?

To find the amount accumulated in the 14 years, we use the formula:

A = P(1 + rt)

Where A is the amount accumulated, P is the principal, r is the interest rate and t is the time.

A = $1650(1 + \frac{3}{100}(14))

A = $1650 + $693 = $2343

Interest = Amount (A) - Principal (P) = $2343 - $1650 = $693

?Eric conducted an experiment in his science class and recorded the data in a table.
Vitek1552 [10]

The constant of proportionality that relates the distance traveled to the elapsed time represented by this data will be 6.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Eric conducted an experiment in his science class and recorded the data in a table.

Eric’s science experiment, time (seconds), 3, 6, 9, 12, 15, 18, distance (ft), 18, 36, 54, 72, 90, 108.

Let x be the time and y be the distance.

Let the distance and time be linear to each other. Then the linear equation is given as

y -  36 = [(36 - 18) / (6 - 3)] (x - 6)

y - 36 = 6 (x - 6)

       y = 36 + 6x - 36

       y = 6x

Then the constant of proportionality that relates the distance traveled to the elapsed time represented by this data will be 6.

More about the linear system link is given below.
