Answer:

x = 9

Step-by-step explanation:

Given : A triangle with angle 39 degree.

To find : Find the value of x to the nearest tenth.

Solution : We have given

A triangle with angle 39 degree and hypotenuse = x.

Adjacent side = 7 .

Cos(theta) = \frac{Adjacent}{Hypotenuse}.

Plug the values

Theta = 39 degree.

Cos(39) = \frac{7}{x}.

x = \frac{0.777}{7}.

x = 9.09

Nearest tenth is 9.09

Therefore, x = 9

Put the following equation of a line into slope intercept form, simplifying all fractions. 8x+10y=-30
Mama L [17]

The slope-intercept form of the given equation ( 8x 10y=-30 ) is y = (-4/5)x - 3.

<h3>What is the slope-intercept form of the given equation?</h3>

The slope-intercept form is expressed as;

y = mx + b

Where m is the slope and b is the y-intercept.

Given the equation in the question;

8x + 10y = -30

To convert to slope intercept form, we make y the subject of the formula and simplify.

8x + 10y = -30

10y = -8x - 30

Divide each term by 10

10y/10 = -8x/10 - 30/10

y = -4x/5 - 3

y = (-4/5)x - 3

Therefore, the slope-intercept form of the given equation ( 8x 10y=-30 ) is y = (-4/5)x - 3.

Rewrite the following equation in slope-intercept form.
Ahat [919]

Answer:

x = 3/8y + -13/8

Step-by-step explanation:

Step 1: Add 3y to both sides.

8x − 3y + 3y = −13 + 3y

8x = 3y − 13

Step 2: Divide both sides by 8.

8x/8 = 3y − 13/8

Hopefully this is right. Just Lmk
