When we take two parallel lines they will create 8 angles, such as 1,2,3,4,5,6,7 & 8. In that angle 6 is 65 degrees. Angles 1,2,3 & $ are in one line and remaining four angles on other line. So Angles 4 and 6 are alternate exterior angles.

Evaluate the equation 4K-10/k=8
solong [7]

Answer:

k = 1 + sqrt(7/2) or k = 1 - sqrt(7/2)

Step-by-step explanation:

Solve for k over the real numbers:

4 k - 10/k = 8

Bring 4 k - 10/k together using the common denominator k:

(2 (2 k^2 - 5))/k = 8

Multiply both sides by k:

2 (2 k^2 - 5) = 8 k

Expand out terms of the left hand side:

4 k^2 - 10 = 8 k

Subtract 8 k from both sides:

4 k^2 - 8 k - 10 = 0

Divide both sides by 4:

k^2 - 2 k - 5/2 = 0

Add 5/2 to both sides:

k^2 - 2 k = 5/2

Add 1 to both sides:

k^2 - 2 k + 1 = 7/2

Write the left hand side as a square:

(k - 1)^2 = 7/2

Take the square root of both sides:

k - 1 = sqrt(7/2) or k - 1 = -sqrt(7/2)

Add 1 to both sides:

k = 1 + sqrt(7/2) or k - 1 = -sqrt(7/2)

Add 1 to both sides:

Answer: k = 1 + sqrt(7/2) or k = 1 - sqrt(7/2)

What is the equation in point-slope form of the line passing through (−2, 0) and (2, 8)? (1 point) y = 2(x + 2) y = 2(x − 2) y =
Sonja [21]

Answer: y=2(x+2)

Step-by-step explanation:

The slope of the line is

y=\frac{8-0}{2-(-2)}=\frac{8}{4}=2

Using the point (-2, 0) to substitute into point-slope form, we get the equation to be \boxed{y=2(x+2)}

If 2x+ y= 10 and y=3x find the value of both x and y
Marat540 [252]

Given the set of equations:

2x + y = 10

y = 3x

Let's solve for x and y.

Here, let's use substitution method.

Substitute 3x for y in equation 1:

2x + y = 10

2x + 3x = 10

5x = 10

Divide both sides by 5:

\begin{gathered} \frac{5x}{5}=\frac{10}{5} \\  \\ x=2 \end{gathered}

In equation 2, substitute 2 for x to find y.

y = 3x

y = 3(2)

y = 6

Therefore, we have:

x = 2 and y = 6

ANSWER:

x = 2, y = 6

I need help with this question. use absolute value<br><br>9 = |X+5|​
Reptile [31]

Answer:

x = -14, 4

Step-by-step explanation:

9 = |x + 5|

~Split into 2 equations

x + 5 = -9 and x + 5 = 9

~Solve for x in both

x + 5 = -9

x = -14

x + 5 = 9

x = 4

Best of Luck!
