Answer:

(b) $\displaystyle -\frac{1}{2} = m$

(a) $\displaystyle 2 = m$

Step-by-step explanation:

Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE <em>RATE OF CHANGES</em> [<em>SLOPES</em>], whereas Parallel Lines have SIMILAR <em>RATE OF CHANGES</em> [SLOPES].

I need help asap!!!!

Answer:

24: x = 31

25: x = 15

Step-by-step explanation:

Remark

24 is supplementary which means that the two angles add to 180o which is on the right hand side of the equation

25 is complementary which means that the two angles add to 90o which is on the left hand side of the equation

Twenty Four

3x + 31 +2x - 6 = 180 Collect the like terms

3x +2x + 31 - 6 = 180 Do the adding and subtracting.

5x + 25 = 180 Subtract 25 from both sides

5x + 25 - 25 = 180 - 25

5x = 155 Divide by 5

x = 155/5

x = 31

Check

3x + 31 = 3*31 + 31

3x + 31 = 93 + 31

3x + 31 = 124

2x - 6 = 2*31 - 6 = 62 - 6 = 56

Total 124 + 56 = 180 as it should.

Twenty Five

Equation

3x+ 4x - 15 = 90

Solution

7x - 15 = 90 Like terms have been collected on the left.

7x = 90 + 15 15 was added to both sides

7x = 105 Divide by 7

x = 15 I'll leave the check to you
