Point because a point can't b defined
Answer:
1/16
Step-by-step explanation:
Of the 16 ways you can answer the 4 questions, only one of those ways has all answers correct.
Each question can be answered 2 ways, and the answer to each one is independent of the answer to any other. So, there are 2·2·2·2 = 2^4 = 16 ways to answer the 4 questions.
Answer:
for soln 1: X < -2; for soln 2: X < 1
Step-by-step explanation:
This is two set problem involving inequality. Therefore, you have to solve for each side of the inequality to know the values of X for each sides.
1 < X + 3 < 4
Soln 1. solve for the first side of the inequality
1 < X + 3
1 - 3 < X
-2 < X
X > -2
soln 2: solve for the second side of the inequality
X +3 < 4
X < 4 - 3
X < 1
Therefore, X > -2; X < 1
Try graphing using the x-intercept and y-intercept.
-15x - 5y = 45
Put in x = 0 to get -5y = 45, making y = -9. Point (0, -9) is on the line.
Put in y = 0 to get -15x = 45, making x = -3. Point (-3, 0) is on the line.
-2x + 6y = 6
Put in x = 0 to get 6y = 6, making y = 1. Point (0, 1) is on the line.
Put in y = 0 to get -2x = 6, making x = -3. Point (-3, 0) is on the line.
(We've actually stumbled on the solution since (-3, 0) is on both lines!)
Graph the two lines using the points found above.
The solution is x = -3, y = 0.
