Vikki [24]3 years ago
8 0
A) This one has no solutions because the answer of the equation is 0=-1 which isn't true.

b) 6t-3=3t+6  ==>  3t=9  ==>  t=3  This means that this has one solution.

c) 6 (2m-3)-3m=2m-18+m  ==> 12m-18=2m-18+m  ==> 9m=0  ==> m=0 so this one has no solutions. 

d) 10+3y-2=4y-y+8  ==>  8+3y=3y+8  ==>   0=0 ==> Infinitely many solutions.

~Hope I helped!~

Which equation is g(f)
Strike441 [17]

Answer: B. g(x) = |x| - 5

Step-by-step explanation: To translate an absolute value graph (|x|) you have to subtract 5 from the absolute value from the equation |x| but not from the value x. For example, if you did g(x) = |x - 5| then you would get a graph that is moved 5 spaces to the right. This is not what we want. Likewise if we did g(x) = |x + 5| then we would get a graph moved 5 spaces to the left. This is not what we want either.

To get a translated graph that moves down the y-axis (vertical axis), we have to subtract the equation |x| 5 units. This then moves it down 5 units to the y axis from the center.
