Answer:

y = 4x - 6

Step-by-step explanation:

Given the following data;

Slope, m = 4

Intercept, c = -6

To write the equation of line in the slope-intercept form;

The standard equation of straight line is given by the formula;

y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

Substituting the values, we have;

y = 4x + (-6)

y = 4x - 6

What is an estimate of the solution. If the equation 6n + 3 = 2? Use a table.
kodGreya [7K]
I don't know how to use the table but to solve the problem:


1. Subtract 3 from both sides
6n=2-3

2. Simplify 2-3 to -1
6n=-1

3. Divide both sides by 6
n=1/6

(20 points)Solve the equation cos x = sin (x + 22)
Law Incorporation [45]

Answer:

\bold{x = 34^\circ}

Step-by-step explanation:

Given:

cos x = sin (x + 22^\circ)

To solve:

The given equation.

Solution:

First of all, let us consider an important property of sine and cosine.

sin(90^\circ-\theta )=cos\theta

OR

cos(90^\circ-\theta )=sin\theta

We can apply above property to solve for x as per given equation.

cos x = sin (x + 22^\circ)

Changing cosx to sine form:

cosx=sin(90^\circ-x)

cosx=sin(90^\circ-x) = sin(x+22^\circ)

\therefore 90^\circ-x=x+22^\circ\\\Rightarrow 90^\circ-22^\circ=x+x\\\Rightarrow 2x=68^\circ\\\Rightarrow \bold{x = 34^\circ}

So, solution to the equation cos x = sin (x + 22^\circ) is:

\bold{x = 34^\circ}
