The point-slope form of the equation of the line that passes through (–5, –1) and (10, –7) is . What is the standard form of the

kvasek [131]

Answer:

Point-Slope form: $y+1=-\frac{6}{15}(x+5)\\$

standard form: $2x+5y=-15$

Step-by-step explanation:

The standard form is given by: $Ax+By=C$

The point-slope form is given by: $y-y_1=m(x-x_1)$

Let's call $(-5,-1)$ as point $(x_1,y_1)$ , and

point $(10,-7)$ as point $(x_2,y_2)$

We also know that the slope $m$ is given by $m=\frac{y_2-y_1}{x_2-x_1}$

Let's find the slope:

$m=\frac{-7-(-1)}{10-(-5)}=-\frac{6}{15}$

1. So, point slope form can be written as:

$y-(-1)=-\frac{6}{15}(x-(-5))\\y+1=-\frac{6}{15}(x+5)\\$

2. Rearranging this equation and bringing all x's and y's to one side and the number to another side will give us the standard form. So:

$y+1=-\frac{6}{15}x-2\\y+\frac{6}{15}x=-2-1\\y+\frac{6}{15}x=-3$

But A, B, and C (standard form) needs to be integers, so to get rid of the denominator , we multiply the whole equation by 15. So we have:

$y+\frac{6}{15}x=-3\\15y+6x=-45$

We can factor out a 3, so it becomes:

$15y+6x=-45\\5y+2x=-15$

So standard form is $2x+5y=-15$

A water sprinkler sends water out in a circular pattern. How large is the watered area if the radius of the watering pattern is

Ray Of Light [21]

Answer:

24 pi

Step-by-step explanation:

you basically need to work out the circumeference

circumference=pi times diameter

if the radius is 12, the diameter is 24

so it would be 24 pi

Solve each equation by completing the square. round to the nearest hundredth if necessary.

erastova [34]

To comlete each square, you just have to take the middle term and divide it by 2, then take its square. Add this to both sides of the equation then simplify. The middle term is the 1st degree x variable.

3. x^2+6x =16
-------------------------
(6/2)^2 = 9
x² + 6x + 9 = 16 + 9
(x + 3)² = 25

4. x^2-10x =11
------------------------
(-10/2)² = 25
x² - 10x + 25 = 11 + 25
(x -5)² = 36

5. x^2-9x =0
--------------
(-9/2)² = 81/4
x² - 9x + 81/4 = 81/4
(x - 9/2)² = 81/4

6. x^2+16x =15
---------------
(16/2)² = 64
x² + 16x +64 = 15 + 64
(x + 8)² = 79

7. 3x^2+18x-81=0
----------------
x² + 6x = 27
(6/2)² = 9
x² + 6x + 9 = 27 + 9
(x + 3)² = 36

A polynomial with a general equation of ax² + bx + c = 0 has a root determined using this formula:

$x= \frac{-b \ +/- \ \sqrt{ b^{2}-4ac } }{2a}$

Just substitute the coefficients to the formula to find the roots

8. 1.09, -1.84
9. 3, 1/2
10. No real roots
11. 1.12, -3.12
