What is Point-Slope Form? What is Slope Intercept Form? What is the Slope Formula?

i included pictures please help it closes in 30 minutes pls give exact answers

Answers

Answer:

For the first part

1.) Negative

2.)zero

3.) undefined

4.) positive

The point slope formula is y-y1=m(x-x1). It is best to use if you already know the slope and one other point on the line. It is used to find another point on the line.

The slope-intercept form is used to show a line. To use this form, you need to know the slope and the y-intercept.

The slope formula is y=mx+b. M is the slope while b is the y-intercept.

Four times a number plus three times a second number is negative nine. Twice the first number plus the second number is three.



Call the first number m and the second number n.

Answers

Answer:

m=9

n=-15

Step-by-step explanation:

If you set it up in a systems of equations way, ou would have

    4m+3n=-9

+ . 2m+n=3

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

You would need to cancel out a variable and in my opinion, canceling m out is easier.

  4m+3n=-9

+-4m-2n=-6

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

0m+n=-15

n=-15

you then plug this into one of the equations, (in my opinion the 2nd one is easier)

2m-15=3

2m=18

m=9

this gives you m so you can get the answer

m=9 and n=-15

Find the integers m and n such that (m+n√2)(1-√2)²=-2+2√2​

Answers

Answer:

m = n = 2

Step-by-step explanation:

(m + n√2)(1 - √2)² = -2 + 2√2

(m + n√2)(1 - 2√2 + 2) = -2 + 2√2

(m + n√2)(3 - 2√2) = -2 + 2√2

3m - 2m√2 + 3n√2 - 4n = - 2 + 2√2

(3n - 2m)√2 + 3m - 4n = 2√2 - 2

3n - 2m = 2

4n - 3m = 2

3n - 2m = 4n - 3m

n = m

4n - 3n = 2

n = 2

m = 2

Answer the question, considering an event to be "unusual" if its probability is less than or equal to 0.05. If you drew one card from a standard deck, would it be "unusual" to draw a 6?

Answers

Answer:

No it's not unusual

Step-by-step explanation:

That's an unusual definition for unusual if you don't mind me saying so.

There are 4 sixes in a standard deck of cards without the jokers. There are 52 cards in that deck

4/52 = 0.077

This is greater than 0.05 so it is not unusual.

Let's add the 2 jokers and see what happens.

4/54 = 0.074

That's still not going to get the situation defined as unusual.

Answer:

My guess:

A. Consistent independent

B. Consistent dependent

C. Inconsistent

Step-by-step explanation:

The first is a repeated equation, so it is a consistent independent equation.

The second is consistent, trying to solve the value of Y. But it looks like it needs the other equation to complete it and solve the value of Y.

The third has no pattern, and isn't trying to solve any values, unlike the others. So it is inconsistent.

(Just a quick note, I do not have experience with this, but it is my best guess)

Write the function rule for the function shown below reflected in the given axis.

Let​ g(x) be the reflection of​ f(x) in the ​-axis. What is the function rule for​ g(x)?

​g(x)

nothing

Answers

Answer:

The answer is "[tex]\bold{g(x) = -\frac{1}{2x} \ and \ g(x)= -3x-12}[/tex]".

Step-by-step explanation:

Please find the complete question in the attached file.

[tex]\to f(x) = 4x[/tex]

Following the y-axis reflexion, f(x) is 4(-x) = -4x after a [tex]\frac{1}{8}[/tex] vertical compression factor, f(x) is [tex]\frac{1}{8} \times -4x = \frac{1}{-2x}[/tex]

So, the [tex]g(x) = - \frac{1}{2x}[/tex]  

 The y axis reflecting indicates that its entire function is multiplied by -1  

so, [tex]f(x)=3x+12^{-1}[/tex]

[tex]\to g(x)=-3x-12[/tex]

Answers

Answer:

[tex]x\leq -20[/tex]

values ranging from minus infinity to negative 20

Step-by-step explanation:

we write the inequality associated with the text in terms of the unknown number "x" as:

[tex]\frac{3}{4} x-2\leq -17[/tex]

then, we solve for "x" by adding 2 to both sides, and then isolating "x" on the left as shown below:

[tex]\frac{3}{4} x-2\leq -17\\\frac{3}{4} x\leq -17+2\\\frac{3}{4} x\leq -15\\3\,x\leq -60\\x\leq -\frac{60}{3} \\x\leq -20[/tex]

then, the range of x-values is from minus infinity to negative 20
