Answer:

The value of the x is 1/9.

Step-by-step explanation:

Data provided in the question is:

$3^2/x=81$

To find out:-

the value of x.

Solution for the equation:-

$3^2/x = 81\\9/x=81\\9/81=x\\1/9=x\\$

On solving the given question or equation by using mathematics of algebra we find out the value of x to be 1/9.

7. Write the slope-intercept form of the equation of the line graphed below.

Stels [109]

Answer:

The answer to your question is $y = \frac{-1}{2} x - 1$

Step-by-step explanation:

Process

1.- Get to points of the line

A (-2, 0)

B (0, -1)

2.- Find the slope of the line

Slope = m = $\frac{y2 - y1}{x2 - x1}$

Substitution

m = $\frac{-1 - 0}{0 + 2} = \frac{-1}{2}$

3.- Find the equation of the line

y - y1 = m(x - x1)

Substitution

y - 0 = -1/2(x + 2)

Simplification

y = -1/2x - 1

Find the missing part.

sveta [45]

Answer:

The answer is $a = \frac{15}{4}$

Step-by-step explanation:

We have to:

$cos(\theta) = \frac{adjacent\ side}{hypotenuse}$

So, if we take the 60 degree angle of the smallest triangle, we have to:

$cos(60) = \frac{a}{x}$

We do not know x. But if we take the sine of the angle of 30 degrees and the main triangle we have:

$sin(30) = \frac{x}{15}\\\\x =\frac{15}{2}$

Then:

$cos(60) = \frac{a}{\frac{15}{2}}$

$a = cos(60)\frac{15}{2}$

$a = \frac{15}{4}$
