Answer:
the answer would be -13n-23
Step-by-step explanation:
first you want to distribute the brackets
-7(2+n) = -14-7n
+(-9-6n)
-9-6n
-14-7n-9-6n
combine the n value with an n value and an integer that doesn't have an n value
-7n-6n-14-9
= -13n-23
Answer:
- y = -5/2x + 5
- y = 2x -1
- y = 24/11
- y = 4x + 4
Step-by-step explanation:
To solve for y, subtract the x-term and divide by the coefficient of y.
5x +2y = 10
2y = -5x +10
y = -5/2x + 5
__
2y -4x = -2
2y = 4x -2
y = 2x -1
__
7y +4y = 24
y = 24/11
We assume there is a typo, but cannot tell what it is. Use the same method as described and demonstrated for the other problems.
__
-2x +1/2y = 2
1/2y = 2x +2
y = 4x +4
C 12 minutes is the correct answer. Hope this helps :)
Answer: C. (0, -3)
Step-by-step explanation:
You don't even need to find the function, just mentally graph every point in the options on the graph.
- If it land in the white area, it's not a solution.
- If it land in the blue area or on the line, it's a solution.
<em>The line is not dotted, showing that the inequality is probably either ≥ or ≤, so points on the line do count as solution.</em>
