Answer:
40 years old
Step-by-step explanation:
Let's imagine a+b=63
63-12=51 (since they were both 6 years younger)
A is double B
34+17=51
34/2=17
You need to add the 6 years back onto the mothers age - 34+6=40
40 years old
VUX = vertical line, undefined slope, represented by x = a number.
so look at ur points (3,-5)....and a vertical line is represented by x = a number...so in ur points, the x value is 3, therefore, ur equation is :
x = 3......x will always be 3 no matter what y is.
a) 2 + 3 - 6 = 10 + 4 ⇒ -1 = 14
This is a false statement so it has NO SOLUTIONS, which means it is a CONTRADICTION
b) 17 + 5 = 23 + 4 - 6 ⇒ 25 = 21
This is a false statement so it has NO SOLUTIONS, which means it is a CONTRADICTION
c) 7 + 4 = 5 + 8 + 2 - 10 ⇒ 11 = 5
This is a false statement so it so it has NO SOLUTIONS, which means it is a CONTRADICTION
NOTE: When they make a true statement, then it has infinite solutions and is an Identity
