What is the connection between linear systems and linear functions?

Explain.

Answers

Answer: While all linear equations produce straight lines when graphed, not all linear equations produce linear functions. In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value).

Step-by-step explanation: Hope this helps :)

A linear function of one variable is one whose graph is a straight line. In general, a linear function can be a function of one or more variables. Each term in a linear function is a polynomial of degree one in one of the variables, or a constant. So ()=3+2
f
(
x
)
=
3
x
+
2
is a linear function.

A linear equation has an equals sign, with linear functions on both sides. You can always move everything to one side of the equation, so solving a linear equation is essentially finding the zero of some linear function. 3+2=0
3
x
+
2
=

is a linear equation. A little algebra yields =−23.

It does get murky because the notation is overloaded. Consider =3+2.

We normally think of that as a function of a single variable
x

. But it’s also a linear equation in two variables

Which graph of ordered pairs shows a proportional relationship?


(Provide an explanation if you can! Thanks.)

Answers

Answer:

1 and 4 i think they look proportional

Answer:

Only the first graph

Step-by-step explanation:

In order for a equation to be proportional it has to have a straight line (which indicates that it has a constant rate of change.) and it has to go through the origin

If  you were to draw a line straight through the ordered pairs of graph 1 it would be a straight line and it would go through the origin (0,0)

therefore graph one would show a proportional relationship

Answers

Answer:26

Step-by-step explanation:

4.5x2=9+17=26

8.5x2=17

Answer:

26lbs.

Step-by-step explanation:

this problem is quite simple when we break it down

first we multiply each of the amounts of the bags and the boxes by two to represent the two of each items as shown

8 1/2 * 2 = 17

4 1/2 * 2 = 9

then all we have to do is add the two new amounts together and TADA:

17 + 9 = 26

we have our answer

NOTE: when multiplying a fraction, you are multiplying how many parts (the numerator) and NOT the size of the part within the whole number (the denominator) in this case 1/2 * 2 = 2/2 and 2/2 = 1

Answer:

A. Each large envelope costs $1.42

Step-by-step explanation:

To solve this, we want to set up a system of equations.

The first customer paid $12 for 14 postcards & 5 large envelopes.

The total number of dollars paid is $12. This will be on one side of the equal sign.They bought 14 postcards. This will be represented by 14p.They bought 5 large envelopes. This will be represented by 5eThe equation will be: 14p + 5e = 12

The second customer paid $24.80 for 10 postcards & 15 large envelopes.

The total number of dollars paid is $24.80. This will be on one side of the equal sign.They bought 10 postcards. This will be represented by 10p.They bought 15 large envelopes. This will be represented by 15eThe equation will be: 10p + 15e = 24.80

Now let's set up our equations together.

14p + 5e = 12

10p + 15e = 24.80

We will solve this through elimination. First we want to eliminate one variable at a time. We will start with e because we can see that 5 and 15 will simplify easily.

Multiply the first equation by -3 to cancel out the variable e.

-3(14p + 5e = 12) = -42p - 15e = -36

Now set this up for elimination.

-42p - 15e = -36

10p + 15e = 24.80

______________

-32p = -11.2

Divide both sides by -32.

p = 0.35

Each postcard costs $0.35.

Now that we know the value of p, let's plug it into one of equations to find e.

14p + 5e = 12

14(0.35) + 5e = 12

4.9 + 5e = 12

5e = 7.1

e = 1.42

Each large envelope costs $1.42

Check your answer by plugging both values back into the equation you haven't used yet.

10p + 15e = 24.80

10(0.35) + 15(1.42) = 24.80

3.5 + 21.3 = 24.80

24.80 = 24.80

Your answer is correct.

Hope this helps!

The circumference of the circle 1, 2, and will be 43.96, 37.68, and 59.66.

What is the circumference of a circle?

Let d be the diameter of the circle.

The circumference of the circle will be

C = πd units

If the diameter is 14 ft, then the radius will be 7 ft, and the circumference will be

C = πd = 3.14 x 14 = 43.96 feet

If the radius is 6 ft, then the diameter will be 12 ft, and the circumference will be

C = πd = 3.14 x 12 = 37.68 feet

If the diameter is 19 ft, then the radius will be 9.5 ft, and the circumference will be

C = πd = 3.14 x 19 = 59.66 feet

The circumference of the circle 1, 2, and will be 43.96, 37.68, and 59.66.

Step-by-step explanation:

We can use the Pythagorean Theoreom for this.

Since we are trying to find the hypotenuse, we know that the hypotenuse is [tex]c^2[/tex]

So, here we are:

[tex]a^2+b^2=c^2\\a^2=24\\b^2=18\\18^2+24^2=c^2\\324+576=c^2\\900=c^2\\[/tex]
