It is d- the function is a line
Answer:
x=1 y=19
Step-by-step explanation:
Let's solve your system by elimination.
−9x+y=10; 10x−y=−9
−9x+y=10
10x−y=−9
Add these equations to eliminate y:
x=1
Then solve x=1 for x:
x=1
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
−9x+y=10
Substitute1forxin−9x+y=10:
(−9)(1)+y=10
y−9=10(Simplify both sides of the equation)
y−9+9=10+9(Add 9 to both sides)
y=19
Hope this helps, I don't really get the answer choices though....
Answer:
0.00039
Step-by-step explanation:
Answer: The equation of a line parallel to the line x=3 that passes through the point (-4,-3) is x = -4.
Solution
The given line x=3 (x=constant) is a vertical line. A line parallel to this line must be a vertical line with equation x=constant, that means the value of x is always the same. Like this line passes through the point (-4,-3) with abscissa x=-4, this abscissa must be constant, then the equation of this line must be x = -4
