12 If mZ1 = 2x + 3 and mZ2 = 3x + 7, which is the value of x?
1
2
A
16
B) 20
C) 34
D) 35

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5

i think it is 24,000 or 460

step-by-step explanation:

12x3=36

12x7=84

let p(x) = - 7.2x + 3 - 2x + 5.6x + 5

now,

6x + 5 = 0

6x = - 5

x = -5/6

using remainder theorem, the remainder when p(x) is divided by 6x + 5 is obtained by calculating p(-5/6).

= 15 + 6 + 3 + (5/3) + 5

= 29 + (5/3)

= 30 2/3

hence, the remainder is 30 2/3.
