Write the slope intercept form of the equation of the line described

Mathematics
1 answer:
Anastasy [175]3 years ago
7 0

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope

b: It is the cut point with the y axis

We have the following equation:

y = 7x-4

So the slope is m = 7

By definition, if two lines are parallel then their slopes are equal, so a parallel line would be of the form:

y = 7x + b

We substitute the given point and find "b":

-4 = 7 (-1) + b\\-4 = -7 + b\\-4 + 7 = b\\b = 3

Finally, the equation is:

y = 7x + 3

Answer:

y = 7x + 3

Rationalise the denominator.
grin007 [14]

Let's see what to do buddy...

_________________________________

To do this, we have to multiply the face and denominator of the fraction by the denominator conjunction, which is :

(5 -\sqrt{2})

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

Reminder :

(a + b)(a - b) =  {a}^{2} -  {b}^{2}  \\

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

So we have :

\frac{1}{ 5-\sqrt{2} } \times  \frac{ 5+\sqrt{2}  }{ 5 +\sqrt{2}  } =  \frac{1 \times ( 5 +\sqrt{2}) }{(5- \sqrt{2} )( 5 +\sqrt{2})  } =  \\

The other is in the photo.

_________________________________

And we're done.

Thanks for watching buddy good luck.

Help! Algebra! please answer if you only know! and make it undertanding!
snow_lady [41]
1. a. Pretty much, you just have to rearrange it so that the highest power is in the front. So, here's your answer:
-6x^4+4x^2+2
b. It's a 4th-degree polynomial. A degree means that "what's the highest power?"
c. It's a trinomial. It has 3 terms, hence it's a trinomial.

2. a. Since it's an odd power and a negative coefficient, it will be:
x→∞, f(x)→-∞
x→-∞, f(x)→∞
b. The degree is even and the coefficient is negative, so it will be:
x→∞, f(x)→-∞
x→-∞, f(x)→-∞

3. a. This basically means that if you solve for x, you should get -2, 1, and 2. So, to do this, you can just write it in factored form and multiply inwards using any method of your choice (remember that in the parentheses, you should get the above value if you solve for x):
f(x) = (x-2)(x+2)(x-1)
If you multiply it out, you get (also your answer):
x^3-x^2-4x+4

4. The zeros are at x = 3, 2 and -7. Multiplicity of 3 is 1, for 2 it's 2, and for -7 it's 3.

Hope this helps!
