Find all the real square roots of -49

Answer:

Step-by-step explanation:

1. Write the equation in point slope form. Remember, point slope form looks like this: y-y1=m(x-x1), with m representing slope. With this equation, you plug in the y coordinate for y1 and the x coordinate for x1. So, it will look like this

y+6=2/3(x+5)

2. Then, convert that into slope intercept form, which is y=mx+b.

y+6=2/3x+10/3 (2/3 * 5)

y= 2/3x - 8/3 (10/3 - 6)

Therefore, your slope-intercept form of the equation is: y=2/3x - 8/3

3. From there, you can graph the line. See the graph in the image attached.

Answer:

To make math easy for my students, whenever I become a math teacher, is the sole purpose why I want to be an educator. To understand how to make math easy, one needs to understand the whats, hows, whys of why people struggle with math.

Most people do not relate to math well and it usually starts around the middle/highschool level.

It's really no one's fault, to be honest.

At some point after arithmetic people start to lose sight, rather never realize what math is actually about. Math is more than counting, it is about critical thinking, logic, reason, pattern, and theory, way more than just digits. Yet, common education( at least here in the US) teaches to follow steps to solve problems as if it were a cookbook, just memorize the recipe and your good to go. If one gets the right or wrong answer, they would be lost as to explain what is truly happening.

Example Learning algebra I followed steps to solve for “x. ” Yet, I never knew, truly, what I was doing. All I remember thinking was the y intercept helped me get the “x.” Only later in self study in college did I bump into the fundamental theorem of algebra…. It all made sense. That moment put it into perspective for me.

If we want people to be good at math we have to give perspective on what is being taught, either presenting theory(which Uncle Sam should do), or simply by giving the bigger picture. With my example, to many people, they see it as a whole bunch digits and letters, get confused, and rightly so. If we explain to someone what's going down, that we are studying lines and that the intercepts(roots) help us better study(analyze) and capture these here lines and curves.

“Mr. Teacherman, Why do we need to study lines and cruves?” Great question student! To help us better understand the world around us. Just studying these simple curves on a graph may seem meaningless, but it forms the basis for things that aid us in many human endeavors, from building edifices to computer programming.

I wish that teachers did that in every class everyday.

In the US, we follow the cookbook method disservicing an entire country, especially those who are on the lower end of society.

Answer:

  33.5 minutes

Step-by-step explanation:

There are many ways you can look at this problem. One is to write equations for the amount in each can, and solve for the time that makes those amounts equal. Another is to consider how much time it takes to reduce the volume by half.

Using the first method, we have ...

  335 -5t = 5t

  335 = 10t

  335/10 = 33.5 = t

It takes 33.5 minutes for the cans to have the same amount.

Answer:

  x ≥ 16  or  x < 0

Step-by-step explanation:

You want ...

  (x -4)/x ≥ 3/4

  4(x -4) ≥ 3x . . . . . . multiply by 4x (requires x > 0)

  4x -16 ≥ 3x

  x ≥ 16 . . . . . . . . . . add 16-3x

__

For x < 0, multiplying by 4x gives ...

 4(x -4) ≤ 3x

  4x -16 ≤ 3x

  x ≤ 16 . . . . . and x < 0

__

There are two sets of solutions:

  x < 0  or  x ≥ 16

Answer:

1, 4, 16, 64, 256

Step-by-step explanation:

The sequence follows the rule: n * 4

1 * 4 = 4

4 * 4 = 16

16 * 4 = 64

Multiply 64 by 4.

64 * 4 = 256

Step-by-step explanation:

Step-by-step explanation:

know:

Loan A

Principal

$4500

Interest rate

5%

Time in years

3

If 100% => $4500

5% =>X

X = 5% × $4500 ÷ 100% = $225

Loan A = $4500 + $225 = $4725

Loan B

Principal

$4300

Interest

6%

Time in years

3

If 100% => $4300

6% =>X

X = 6% × $4300 ÷ 100% = $258

Loan B = $4300 + $258 = $4558

Loan B has the lowest total payback.

The Loan B has the lowest total payback than the Loan A.

WE can calculate the payback in both loan as;

Loan A;

Principal = $4500

Interest rate = 5%

Time in years = 3

If 100% => $4500

X = 5% × $4500 ÷ 100%

X = $225

Loan A = $4500 + $225 = $4725

Loan B;

Principal = $4300

Interest = 6%

Time in years = 3

If 100% => $4300

X = 6% × $4300 ÷ 100%

X= $258

Loan B = $4300 + $258 = $4558

Hence, the Loan B has the lowest total payback than the Loan A.

Answer:

1 1/4 is 10 minutes less than 1 hour and 25 minutes

Step-by-step explanation:

1 1/4 is equivalent to 1 hour and 15 minutes.

We get this by taking the 60 minutes we know are in an hour and multiplying  it by the 1/4

[tex]\frac{60}{1} *\frac{1}{4} = \frac{60}{4} = 15[/tex]

The difference between 25 minutes and 15 minutes is 10 minutes.

Answer:

It is going to be the first one on the top left.

Step-by-step explanation:

the rule for something to be a function is every input must have exactly one output. now that does not mean that two different inputs cannot have the same output. but on a vertical line test every other one would be wrong.

A relation will be a function if for every single input there is only one output thus option (A) is correct.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

As per the given diagrams,

A relation will be a function if for every single input there is only one output.

In the second diagram for input = 5 the output is 2 and -3 so it will not a function. Similarly third and fourth will also not function.

In the first diagram for  every single input there is only one output.

Hence "A relation will be a function if for every single input there is only one output".
