The absolute value of BOTH of those numbers is ' 1 '.
==========================================
Oh ! Wait just a second. Did you mean for the 1 and the -1 to be combined
in some way ? If that's what you had in mind, then you'll have to be more
specific. "And" is no mathematical operation that I know of.
Answer:
She has 28 pennies
Step-by-step explanation:
Janae has 280 dimes in her piggy bank she has 10 times as many pennies .
If she has 280 dimes in piggy bank
And has 10 times as many pennies
Let dimes= x
Let pennies= y

Answer:
C and D
Step-by-step explanation:
in equations y=4x+9 and y=4x-9 you have the same slope (4) so paralleling is guaranteed.
y=9 and y=18 you can understand as y=0x+9 and y=0x+18, so in this situation you have the same slope (0), so lines y=9 and y=18 are parallel too.
