X+5y=-5 slope and y-intercept

Mathematics

First, you'd need to transform the equation into y = mx + b

To do this, set up the original equation and solve for y.

x + 5 y = -5
Subtract x from both sides.
5y = -5 - x
Now, divide by 5 into both sides to leave y on one side.
y = -1 -x/5

With this new equation, just shift the numbers on the right of y to create a y = mx + b equation

y = -x/5 - 1

Therefore, you're y intercept is -1 and you're slope is -x/5.

Hope this helps!

You take the x and subtract it from both side that will leave you with 5y= -x-5 , then you take the 5 from 5y and divide it with everything that will leave you with y= -1/5x- 1. The slope would be -1/5 and the y-intercept is -1

What is the surface area of the regular pyramid given below?
yuradex [85]

For this case we have by definition, that the total surface area of a regular pyramid with a square base is given by:

SA = \frac {1} {2} p * S + A_ {b}

Where:

p: It is the perimeter of the base

S: It's the inclination

A_ {b}: It is the area of the base

Substituting:

A_ {b} = 7 ^ 2 = 49units ^ 2\\p = 7 + 7 + 7 + 7 = 28units\\S = 10units\\SA = \frac {1} {2} 28 * 10 + 49\\SA = 140 + 49\\SA = 189 \ units ^ 2

Nonamiya [84]

If <em>n</em> = 0.151515…, then 100<em>n</em> = 15.151515…

Then

100<em>n</em> - <em>n</em> = 15.151515… - 0.151515…

99<em>n</em> = 15

<em>n</em> = 15/99 = 5/33

Multiply (x-1)(x³+4x²+4x-1) and combine like terms. Explain how you reached your answer.
Hitman42 [59]

Answer:

x⁴+3x³ -5x +1

Step-by-step explanation:

To multiply this we are going to <u>multiply each term of the binomial by each term of the polynomial.</u>

(x-1)(x^{3}+4x^{2}  +4x-1)\\=x^4+4x^3+4x^2-x -x^3-4x^2-4x+1

Now we are going to <u>combine like terms (this means we are going to sum up terms with the same exponent)</u>

x^4+4x^3+4x^2-x -x^3-4x^2-4x+1 = x^4 +(4x^3-x^3)+(4x^2-4x^2)+(-x-4x)+1\\=x^4+3x^3-5x+1

Thus, the answer is x⁴+3x³ -5x +1
