What is the equation in point slope form of the line that passes through the point (-1,-3) and has a slope of 4?

Mathematics

kow [346]2 years ago
5 0

Answer:

a

Step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

here m = 4 and (a, b ) = (- 1, - 3 ) , then

y - (- 3) = 4(x - (- 1) ) , that is

y + 3 = 4(x + 1)

The sum of two numbers is 26. The larger number is 5 more than twice the smaller. What are
babymother [125]

Answer:

Step-by-step explanation:

Let n = the smaller of the two numbers, and since the other number is 5 more than twice the smaller number n, then ...

Let 2n + 5 = the second and larger number.

Since the sum of the two unknown numbers is 26, then we can write the following equation to be solved for n as follows:

n + (2n + 5) = 26

n + 2n + 5 = 26

Collecting like-terms on the left, we get:

3n + 5 = 26

3n + 5 - 5 = 26 - 5

3n + 0 = 21

3n = 21

(3n)/3 = 21/3

(3/3)n = 21/3

(1)n = 7

n = 7

Therefore, ...

2n + 5 = 2(7) + 5

= 14 + 5

= 19

CHECK:

n + (2n + 5) = 26

7 + (19) = 26

7 + 19 = 26

26 = 26

Therefore, the two desired numbers whose sum is 26 are indeed 7 and 19.

Am I dealing with harmonic stuff (trig)?
pochemuha

You just need to solve for when y=0:

\dfrac{\cos8t-9\sin8t}4=0\implies\cos8t-9\sin8t=0

\implies\cos8t=9\sin8t

\implies\dfrac19=\dfrac{\sin8t}{\cos8t}=\tan8t

\implies8t=\tan^{-1}\dfrac19+n\pi

\implies t=\dfrac18\tan^{-1}\dfrac19+\dfrac{n\pi}8

where n is any integer. We only care about when 0\le t\le1, which happens for n\in\{0,1,2\}.

t=\dfrac18\tan^{-1}\dfrac19\approx0.01

t=\dfrac18\tan^{-1}\dfrac19+\dfrac\pi8\approx0.41

t=\dfrac18\tan^{-1}\dfrac19+\dfrac\pi4\approx0.80
