The equation of the line is y = 3x + 6

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

<h3>How to determine the equation of the line?</h3>

The given parameters are

Slope, m = 3

y-intercept, c = 6

A linear equation is represented as

y = slope * x + y-intercept

i.e.

y = mx + c

So, we have

y = 3x + 6

Hence. the linear equation is y = 3x + 6

german

Answer:

x=2. y=6

Step-by-step explanation:

Step (1)

-6x-3y=-30

-3(-9x-y=-24)

Step (2)

-6x-3y=-30

27x+3y=72

Step (3)

-6x+27x=21x

-30+72=42

Step (4)

21x=42

divide 21 on each side

x=2

Plug x in one of the two equations

to get the y

-6(2)-3y=-30

-12-3y=-30

+12. +12

-3y=-18

divide negative 3

y=6

Answer:

The choice C 31

Step-by-step explanation:

$\frac{21}{x} = \frac{105}{155} \\ 105x = 21 \times 155 \\ 105x = 3255 \\ \\ x = \frac{3255}{105} \\ \\ x = 31$

Given that sin? x + cos2x = 1

Pachacha [2.7K]

Answer:

the answer is

$\frac{ \sqrt{23} }{5}$

cause sin²x= 2/25

so cos²x would be 1-2/25= 23/25

then cos x is what I wrote as the answer
