Find the equation of the straight line with the following gradient point c) 5, (-1,-3)​

Mathematics

Answer:

y = 5x + 2

Step-by-step explanation:

Standard form of Equation of line: y = mx + c

where m = slope or gradient,

c = y-intercept

From the question we know that:

x = - 1

y = - 3

m = 5

We will substitute these values into the equation to find c.

- 3 = (5)(- 1) + c

- 3 = - 5 + c

c = - 3 + 5 = 2

Therefore the equation of this line is: y = 5x + 2

What I the slope of a line that is perpendicular to the line 2y-3x=8
Zolol [24]

<u>ANSWER</u>

-  \frac{2}{3}

<u>EXPLANATION</u>

The given given equation is

2y - 3x = 8

We need to rewrite this equation in the slope-intercept form:

y = mx + b

We add 3x to both sides.

2y  - 3x + 3x=8  + 3x

\implies \: 2y  =  3x + 8

We divide through by 2 to get,

y =  \frac{3}{2}x + 4

The slope of this line is

m =  \frac{3}{2}

Let the slope of the line perpendicular to this line be 'n' .

Then the product of the slopes of two perpendicular lines is always negative 1.

m \times n =  - 1

\implies \:  \frac{3}{2} n =  - 1

\implies \:   \frac{2}{3}   \times \frac{3}{2}n =  - 1 \times  \frac{2}{3}

n =  -  \frac{2}{3}

Therefore the slope of the new line is

-  \frac{2}{3}

If cos ⁡x=−4/5, and 180°
Vladimir [108]

Answer:

180< x < 270 so x is in 3rd quadrant ,hence tan x is positive cos x=-4/5 tan(x/2) = √ {(1 − cos x) / (1 + cos x)) = √ { (1+4/5)/(1–4/5) } =√{ 9/5)/(1/5) } =√9=±3 now ...

What is the value of a?
emmasim [6.3K]

Answer:

A=8

Step-by-step explanation:

If you use the formula 30-60-90 which is a-radical 3a-2a

since the hypotenuse is 2a it equals 16

therefore if its 2a all you need to do is divide it where then you get 8.
