Solve each of the equations independently, then determine if the are continuous or discontinuous.
15≥-3x [start here]
-5≤x [divide both sides by (-3). *Dividing by a negative number means the direction of the sign changes!]
x≥-5 [just turned around for analysis]
Next equation:
2/3x≥-2 [start here]
x≥-2(3/2) [multiply both sides of the equation by the reciprocal, 3/2)
x≥-3
So, (according to the first equation) all values of x must be greater than, or equal to -5.
(According to the second equation) all values of x must be greater than, or equal to -3.
So, when graphed on a number line, both equations graph in the same direction, so they are continuous.
Answer: k = -5
explanation-
distribute: -3k + -21 - 5k + 4= 23
combine: -8k -17 = 23
add 17 to both sides: -8k = 40
divide both sides by -8: k=-5
I believe it is 56 because 7•8 is 56 and 1•56 is 56
Answer:
300 is your answer
Step-by-step explanation:
First add 1 to each side. It will leave you with an equation like this. 5x=3x -4
Next, subtract 3x from each side. It will leave you with an equation like this. 2x= -4
Lastly, divide each side by 2 so we can get x by itself.
ANSWER: x=-2
