Solve the equation. Note if the equation is an identity or if it has no solution. -3(-c-18)=3c-18 A.c=___ B. The equation is an identity C. the equation has no solution
did you try and solve that to get a value for c?
is it -12?
no, you can't solve that for c. -3(-c-18)=3c-18 (-3)*-c - 18*(-3) = 3c - 18 3c + 54 = 3c - 18 54 = -18
ok thanks, can u help with a few others
That is a contradiction, a false statement. The lines are parallel, and have no solution where they intersect
Sure
Use a table to find the solution of the equation. If the solution lies between two consecutive integers, identify those integers. 7.2=3n-4 If the solution is an integer, type this integer. Otherwise, type the two consecutive integers between which the solution lies.
solving for n. 7.2 = 3n - 4 11.2 = 3n n = 11.2 / 3
That is not an integer answer. 11.2/3 is about 3.7333333 that lies between integers 3 and 4
cool ok
Tell whether the given ordered pair is a solution. y=5-3x. (-1,-8) Does the ordered pair -1,-8 satify the solution? A.yes Bno
(x , y) = ( -1 , -8) Just have to put those values, x=-1, y=-8, into the equation and see if it works... y = 5 - 3x -8 = 5 - 3*(-1)
so it is A. yes
-8 = 5 - (-3) -8 = 5 + 3 -8 = 8 that is not true
oh so B.no sorry im kinda bad with math, atleast this stuff
no problem, have to practice it
ok thanks that was my last one, if i need u again ill tag u
