A system of equations is given below.

1 answer:

5 0

First, solve the given system of linear equations.

Second, multiply the first equation by 4 (which was an arbitrary choice). Add your result to the 2nd equation.

You should now have the following:

First equation: No change: <span>2x + 7y = 1

Second equation: 4(</span><span>-3x – 4y = 5) = -12x -16y = 20

Solve this new system of linear equations. Do you (or do you not) obtain the same solution as your earlier one?</span>

It means that all values of x would make it true. Also take a look at the equation when we simplify:

4x + 7 = 1 + 4x + 6
Which simplified turns into
4x + 7 = 4x + 7

So no matter what value you put for x, it will be the same on both sides, making all values true for x.

Joann has a jug containing 128 ounces of milk. She drinks 14 ounces of milk each day. Enter the function f(x) that represents th

Tatiana [17]

Answer:

$f(x)=128-14x$

Step-by-step explanation:

So, we started out with 128 ounces of milk.

Each day, Joann drinks 14 ounces of milk.

Therefore, the amount of milk left over after x days is 14 times x subtracted from 128.

Therefore, our function is:

$f(x)=128-14x$

And we're done!
