Write a function rule for the statement, “The output is 4 less than the input.” Then, complete the table.
Slope:
y-intercept:
equation:

Answers

Answer:5

Step-by-step explanation:

Answers:

Slope:  1y-intercept:  -4equation:     y = x-4y outputs: -4, -3, -2, -1, 0

Those y outputs are placed into the table in the order shown. For instance, -1 goes right underneath the '3'.

========================================================

Explanation:

Let's find the equation first. The function rule is "the output is 4 less than the input". So whatever the input x is, we subtract off 4 to get the output y.

This leads directly to the equation y = x-4

This is the same as saying y = 1x-4 which is in the form y = mx+b

m = 1 is the slope and b = -4 is the y intercept

------------

Once we have the equation, we plug in the given input x values one at a time to find their corresponding y values.

For example, if x = 0, then,

y = x-4

y = 0-4

y = -4

So we have x = 0 pair up with y = -4. We write -4 underneath the 0 in the table given.

Then we write -3 under the "1" in the table because

y = x-4

y = 1-4

y = -3

And so on. Repeat this process until you get to x = 4.

You should have these ordered pairs

x = 0, y = -4x = 1, y = -3x = 2, y = -2x = 3, y = -1x = 4, y = 0

The reason why there is a negative sign in between 6.9 and 5 is that + and - become negative.

$2400

$12,400

Step-by-step explanation:

Simple interest equation:

PV(1+it)

we have

10000(1+.06*4)

10000(1.24)

12400

Subtract the PV to get the interest earned

12400-10000= 2400

We just found that the total would be 12,400 and so part B is already solved

What is the domain in interval notation of f(x)=(x+3)^2

Answers

Given:

The function is

[tex]f(x)=(x+3)^2[/tex]

To find:

The domain of the given function in interval notation.

Solution:

We have,

[tex]f(x)=(x+3)^2[/tex]

Domain is the set of x-values or input values.

The given function is a quadratic function and domain of the quadratic function is all real number. The function is defined for all values of x. So, domain of the given function is the set of all real numbers.

Domain = Set of all real numbers

Domain = (-∞,∞)

Therefore, the domain of the given function is (-∞,∞).

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

An engineer purchased 78 trees at an all-out cost of $4050. The overhanging trees cost $45 each and the evergreens cost $60 each.

Let 'x' be the number of tree shades and 'y' be the number of evergreens. Then the equations are given as,

x + y = 78                               ...1

45x + 60y = 4050                ...2

From equations 1 and 2, then we have

45(78 - y) + 60y = 4050

15y = 540

y = 36

Then the number of tree shades will be given as,

x + 36 = 78

x = 78 - 36

x = 42

The number of tree shades and evergreens will be 42 and 36, respectively.
