Answer:
-8x+10
Step-by-step explanation:
The expression is: -2(3x+x-5)
Step 1: Using order of operations, combine like terms
-2(4x-5)
Step 2: Distribute -2 to each term in the parentheses:
-8x+10
Hence, the simplified expression is:
-8x+10
Answer:
1 1/2
Step-by-step explanation:
4/5. 1/4.
16/20. 5/20 21/20
The answer is x=-6.33333 (-19/3)
First, add like terms (12+7), which would equal to 19.
Then isolate the variable by subtracting 19 and adding it to the other side of the equal sign.
Now with this new equation of 3x=-19, isolate again by dividing 3 from x and do the same thing to the other side (-19/3).
The answer should be -6.33 repeating, but in algebra you would give a more simplified answer. This would be -19/3
Try this solution:
1. In order to built the line required in the condition it need to determine its equation.
Using the coordinates of point B (5;2), if to substitute them into the given equation: 2=-3*5+b, ⇒ b=17. It means, that the equation of the line required in the condition is y= -3x+17.
2. The graph is in the attachment; point (0;17) is the intersection point of Y-axis and the line.
