Answer:
it's b
Step-by-step explanation:
parallel lines stay the same distance away from each other all the time. they could go on forever and would never cross. think of a parallelogram. the lines always stay the same width apart, like train tracks. this would mean that is is b because it does not intersect xy
Subtract 10x
10x + y = -19
10x + 3y = -17
You would get:
-2y = -2
Two negatives make a positive number! Divide
y = 1
Plug in
10x + (1) = -19
10x = -20
Divide
x = -2
Your solutions are
x = -2
y = 1
Answer:
Step-by-step explanation:
In the 3rd question, we are given the equation x ^ 3 + x ^ 2 + 2x + 24. One of the factors is x + 3. Now, we can use long division to find that the equation we have left is x^2 - 2x - 8. We can just factor this to get (x - 4) (x + 2). In the 3rd question, possible factors for the coefficient are 1, 2, -1, -2. Possible factors for the constant are 1, 7, -1, -7. Now, we can try out all of them. The possible factors are 1, 7, -1, -7, 2, 14, -2, -14.
Answer: 7
Step-by-step explanation:
8x +5 = 61
subtract 5 from both sides
8x = 56 divide both sides by 8 to get x by itself
x= 7
The answer should be A
