Answer:
6 it is 6
Step-by-step explanation:
X(domain) = 2
y (range)= -4
Answer:
Step-by-step explanation:
7x - 4y = 3y - 14
7x - 7y = -14
-7y = -7x - 14
y = x + 2
Answer:
Step-by-step explanation:
y - 3 = (-1/2)(x - 2)
Solve 8x-4y+9=0 for y so as to find the slope of this given line:
8x + 9 = 4y, or y = 2x + 9/4. The slope of the given line is 2. The slope of any line perpendicular to this one is the negative reciprocal of 2, which is -1/2.
Use the point-slope formula: y - k = m(x - h ). (h, k) is (2, 3) and m is -1/2.
Then we have: y - 3 = (-1/2)(x - 2)
Given equation is : 11x - 2 + 15 = 8 + 7 + 9x
Solving this by grouping like terms on one side.




Hence, this equation has one solution.
