Best ResponseYou've already chosen the best response.0How many solutions does the equation have? a+5=1/5(5a+25) A. one solution B. infinite solutions C. no solution What about this one i think infinite solutions

Best ResponseYou've already chosen the best response.3\(\large\color{black}{ a+5=\frac{1}{5}(5a+25)}\) like this?

Best ResponseYou've already chosen the best response.3then you are correct  "infinte solutions" is the right answer.

Best ResponseYou've already chosen the best response.3Because when you expand the right side, you get: \(\large\color{black}{ a+5=\frac{1}{5}(5a+25)}\) \(\large\color{black}{ a+5=a+5}\) and that is true for any value of a.

Best ResponseYou've already chosen the best response.0Which expressions would complete this equation so that it has infinitely many solutions? 8 + 2(8x – 6) = Choose exactly two answers that are correct. A. 2(4x + 7) B. 9x – 10 C. 16x – 4 D. 4(4x – 1)

Best ResponseYou've already chosen the best response.38 + 2(8x – 6) = 8 + 16x – 12 = 16x – 4. ` same = same ` > ` 8 + 2(8x – 6) = 16x  4 ` C is right

Best ResponseYou've already chosen the best response.38 + 2(8x – 6) = 8 + 4(4x – 3) = 8 + 4(4x – 1  2) = 8 + 4(4x – 1) + (2)(4) = 8 + 4(4x – 1) 8 = 4(4x – 1) =

Best ResponseYou've already chosen the best response.0What is the best way to classify each equation? Column AColumn B 1. 8x + 24=2(4x+12) 2. 5x + 18x=2(2x+8) 3. 7(3x2)=20x13 4. 3x + 2(x10)=5(x4) A. identity B. contradiction C. neither @SolomonZelman

Best ResponseYou've already chosen the best response.3Can you write the Columns more clearly please?

Best ResponseYou've already chosen the best response.0dont worry about the columns... Column A is with the long equations and Column B is A. identity B. contradiction C. neither

Best ResponseYou've already chosen the best response.3Column A Column B 1. 8x + 24=2(4x+12) 2. 5x + 18x=2(2x+8) 3. 7(3x2)=20x13 4. 3x + 2(x10)=5(x4) like this?

Best ResponseYou've already chosen the best response.0what you have underneath column B is suppose to be under Column A and under Column B is suppose to be this A. identity B. contradiction C. neither

Best ResponseYou've already chosen the best response.3Column A Column B 8x+24=2(4x+12) Identity 5x+18x=2(2x+8) Contradiction 7(3x2)=20x13 Niether 3x+2(x10)=5(x4) like this?

Best ResponseYou've already chosen the best response.3`(When you expand 1st row, 1st column)` 8x+24=2(4x+12) \(\longrightarrow\) 8x+24=8x+24

Best ResponseYou've already chosen the best response.3`(Expand 2nd row, 1st column)` 5x+18x=2(2x+8) \(\longrightarrow\) 5x+18x=4x+16 `(Subtract x from 5x: 5xx=4x)` 5x+18x=4x+16 \(\longrightarrow\) 4x+18=4x+16

Best ResponseYou've already chosen the best response.3So at this point you should be able to tell me whether A is an *identity* (true for all values of x), a *contradiction* (true for NO values of x  i.e. always false) OR *Niether* (not contradition or identity  i.e. has 1 solution)

Best ResponseYou've already chosen the best response.3`(Expand 3rd row, 1st column)` 7(3x2)=20x13 \(\longrightarrow\) 21x14=20x13 `(Subtract 20x from both sides)` 21x14=20x13 \(\longrightarrow\) x14=13 `(Add 14 to both sides)` x14=13 \(\longrightarrow\) x=27 (and this is Niether)

Best ResponseYou've already chosen the best response.3`(Expand 4th row, 1st column)` 3x+2(x10)=5(x4) \(\longrightarrow\) 3x+2x20=5x20 `(Add like terms on the left side)` 3x+2x20=5x20 \(\longrightarrow\) 5x20=5x20 Can you identify this one as either: *identity*, *contradiction*, or *Neither*
