Find The Value Of X.

Answer 1
The triangle is always 180 degrees
6x + 8x + 7 + 8x - 3 = 180
Simplify
22x + 4 = 180
Minus 4 from both sides
22x = 176
Divide 22 by both sides
X = 8
Can I get brainliest answer
Answer 2

Answer:

x = 8

Step-by-step explanation:

All angles of a triangle must add up to 180 degrees.

So 8x + 7 + 6x + 8x - 3 = 180

Combine like terms

22x + 4 = 180

Subtract 4

22x = 176

Divide

22x ÷ 22 = 176 ÷ 22 = x = 8

We can make sure this is correct by plugging in 8 for all x terms.

8(8) + 7 + 6(8) + 8(8) -3

64 + 7 + 48 + 64 - 3 = 180.

X = 8

Hope this helps.

(-3,-1)
a. The equation of line k in slope-intercept form is
(Use integers or fractions for any numbers in the equation. Simplify your answer.)

Answers

a) The equation of line k is:

[tex]y = -\frac{202}{167}x + \frac{598}{167}[/tex]

b) The equation of line j is:

[tex]y = \frac{167}{202}x + \frac{1546}{202}[/tex]

The equation of a line, in slope-intercept formula, is given by:

[tex]y = mx + b[/tex]

In which:

m is the slope, which is the rate of change.b is the y-intercept, which is the value of y when x = 0.

Item a:

Line k intersects line m with an angle of 109º, thus:

[tex]\tan{109^{\circ}} = \frac{m_2 - m_1}{1 + m_1m_2}[/tex]

In which [tex]m_1[/tex] and [tex]m_2[/tex] are the slopes of k and m.

Line k goes through points (-3,-1) and (5,2), thus, it's slope is:

[tex]m_1 = \frac{2 - (-1)}{5 - (-3)} = \frac{3}{8}[/tex]

The tangent of 109 degrees is [tex]\tan{109^{\circ}} = -\frac{29}{10}[/tex]Thus, the slope of line m is found solving the following equation:

[tex]\tan{109^{\circ}} = \frac{m_2 - m_1}{1 + m_1m_2}[/tex]

[tex]-\frac{29}{10} = \frac{m_2 - \frac{3}{8}}{1 + \frac{3}{8}m_2}[/tex]

[tex]m_2 - \frac{3}{8} = -\frac{29}{10} - \frac{87}{80}m_2[/tex]

[tex]m_2 + \frac{87}{80}m_2 = -\frac{29}{10} + \frac{3}{8}[/tex]

[tex]\frac{167m_2}{80} = \frac{-202}{80}[/tex]

[tex]m_2 = -\frac{202}{167}[/tex]

Thus:

[tex]y = -\frac{202}{167}x + b[/tex]

It goes through point (-2,6), that is, when [tex]x = -2, y = 6[/tex], and this is used to find b.

[tex]y = -\frac{202}{167}x + b[/tex]

[tex]6 = -\frac{202}{167}(-2) + b[/tex]

[tex]b = 6 - \frac{404}{167}[/tex]

[tex]b = \frac{6(167)-404}{167}[/tex]

[tex]b = \frac{598}{167}[/tex]

Thus. the equation of line k, in slope-intercept formula, is:

[tex]y = -\frac{202}{167}x + \frac{598}{167}[/tex]

Item b:

Lines j and k intersect at an angle of 90º, thus they are perpendicular, which means that the multiplication of their slopes is -1.

Thus, the slope of line j is:

[tex]-\frac{202}{167}m = -1[/tex]

[tex]m = \frac{167}{202}[/tex]

Then

[tex]y = \frac{167}{202}x + b[/tex]

Also goes through point (-2,6), thus:

[tex]6 = \frac{167}{202}(-2) + b[/tex]

[tex]b = \frac{(2)167 + 202(6)}{202}[/tex]

[tex]b = \frac{1546}{202}[/tex]

The equation of line j is:

[tex]y = \frac{167}{202}x + \frac{1546}{202}[/tex]

Answer:

Step-by-step explanation:

The value of x is 100 meters if the shipwreck is 300 meters away from a diving station. An undersea explorer travels away from the station at a speed of 2 meters per second.

What is the distance?

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

It is given that:

A shipwreck is 300 meters away from a diving station.

An undersea explorer travels away from the station at a speed of 2 meters per second.

The explorer is x meters away from the station and will reach the

shipwreck in 100 seconds.

As we know,

Distance = time×speed

Distance = 100×2

Distance = 200 meterse

x = 300 - 200

x = 100 meters

Thus, the value of x is 100 meters if the shipwreck is 300 meters away from a diving station. An undersea explorer travels away from the station at a speed of 2 meters per second.

Answers

Answer:

the perimeter of the square is 104

Step-by-step explanation:

to find the perimeter of a square we need to use the formula P = 4a

P is perimeter and a is the side of the square

if a is the side and the formula of Area is A = a^2

that means the side of the square is a = 26 because 26 * 26 = 676

now we take 26 and place it in the a spot of the perimeter formula

P = 4 * 26   (P = 104)

Answers

Answer:

Step-by-step explanation:

For number 8, to start,:

[tex]\frac{x}{4}[/tex] - 1 = 1

the first step is to add 1 to both sides of the equation; then, simplify.

[tex]\frac{x}{4}[/tex] - 1 = 1

   +1    +1

----------------

next, the -1 and +1 will cancel.

[tex]\frac{x}{4}[/tex] = 2

the last step is to multiply both sides of the equation by 4.

4 · [tex]\frac{x}{4}[/tex] = 2 · 4

simplify; the 4s cancel out on the left side.

x = 8

**************************************************

For number 9, :

9 = 6 + [tex]\frac{x}{7}[/tex]

like in number 8, the first step is to subtract 6 from both sides of the equation; also, a helpful tip you can use is move the 9 to the right side; speaking personally, it often helps make things visually easier to work out. you would then rewrite the equation like: 6 + [tex]\frac{x}{7}[/tex] = 9

6 + [tex]\frac{x}{7}[/tex] = 9

now, we'd subtract 6 from both sides.

6 + [tex]\frac{x}{7}[/tex] = 9

-6         -6

-----------------

next, the 6 and -6 will cancel.

[tex]\frac{x}{7}[/tex] = 3

the last step is to multiply both sides of the equation by 7.

7 · [tex]\frac{x}{7}[/tex] = 3 · 7

simplify; the 7s cancel out on the left side.

x = 21

Answers

Answer:

a. 1 1/2 (or 3/2)

b. 2/3

c. 1

d. 1

Step-by-step explanation:

Part A: (1,1) (7,5)

To determine the slope, you will use the equation m=(y2-y1)/(x2-x1). Keep in mind that it doesn't matter what point you use for (x1, y1) or (x2, y2).

Let's plug in the numbers for part a:

m=(7-1)/(5-1)

Let's then solve the problems inside the parentheses:

m=6/4

And finally, we simplify:

m=3/2 (or 1 1/2 depending on what your teacher wants for an answer)

For these others, I will just go through the steps and not explain them, if you need help or don't understand something I'm doing, either look back at what I did for part a or comment on this answer.

Part B: (1,1) (5,7)

m=(5-1)/(7-1)

m=(4/6)

m=2/3

Part C: (2,5) (-1,2)

m=(-1-2)/(2-5)

m=(-3/-3)

m=1

Part D: (2,5) (-7,-4)

m=(-7-2)/(-4-5)

m=(-9/-9)
