Answer:

x = 3.2

Step-by-step explanation:

Since, intercepts made by parallel lines on the transversals are in proportion.

\therefore \frac{AB}{BC} =\frac{EF}{FG}... (1)

AB = BC.... (given)

\implies \frac{AB}{BC} = 1..... (2)

From equations (1) & (2)

1 =\frac{EF}{FG}

{FG}={EF}

Therefore,

7x - 9 = 2x + 7

7x - 2x = 9 + 7

5x = 16

x = 16/5

x = 3.2

Norma-Jean [14]

Answer:

y + 4 = -\frac{5}{6}(x - 8)

Step-by-step explanation:

In the Point-Slope Formula, y - y_1 = m(x - x_1),all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS.

Can someone help me part 2
Otrada [13]

Step-by-step explanation:

y = ¼x + 2

m1 = ¼

m of line perpendicular = m2

the formula is : m1×m2 = -1

=> m2 = -1 ÷ m1

= -1 ÷ ¼ = -4

so, the equation is :

y = -4x - 7 (option A)

Please help me find measure of angle LKM if measure of angle LKN = 145°​
natali 33 [55]

Answer:

56

Step-by-step explanation:

The thing to realize is that the total of both angles that have x in them is that they add to 145. That's given.

<LKM + <MKN = 145

2x + 10 + 4x - 3 = 145              Combine like terms

6x + 7 = 145                             Subtract 7 from both sides

6x = 138                                   Divide by 6

x = 138/6

x = 23

That's not the answer.

2x + 10 = <LKM

2*23 + 10 = <LKM

46 + 10 = <LKM

56 = <LKM

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Distributive Property

<u>Algebra I</u>

  • Combining Like Terms

Step-by-step explanation:

<u>Step 1: Define</u>

(6x² - 4x + 2) - (-2x² + 3x - 5)

<u>Step 2: Simplify</u>

  1. Distribute negative:                    6x² - 4x + 2 + 2x² - 3x + 5
  2. Combine like terms (x²):             8x² - 4x + 2 - 3x + 5
  3. Combine like terms (x):               8x² - 7x + 2 + 5
  4. Combine like terms (Z):              8x² - 7x + 7
