Answer:
Step-by-step explanation:
A) 5x - 7 = 5x becomes -7 = 0 if 5x is subtracted from both sides. This result is never true, so NO SOLUTION
B)3x−9=3(x−3) Performing the indicated multiplication, we get
3x - 9 = 3x - 9. This is always true, so there are INFINITELY MANY SOLUTIONS
C)2x−6=−2(x−3) Performing the indicated multiplication, we get
2x - 6 = -2x + 6. Adding 2x - 6 to both sides results in
4x - 12 = 0, or 4x = 12. Thus, the solution is x = 3. ONE SOLUTION
D)2x+6−5x=−3(x This equation is incomplete
Answer:
19/5
Step-by-step explanation:
Answer: y=kx/w^2
Step-by-step explanation:
y is directly proportional to x
y∝x
y=kx
y inversely proportional to the square of w.
y ∝ (1/(w)^2)
y=k/w^2
y=kx/w^2
Answer:

Step-by-step explanation:
Answer:
y = 9x - 5
Step-by-step explanation:
Any line parallel to the given line y = 9x must also have the slope 9.
Substitute the known values (m = 9, h = 0, k = -5) into the point-slope equation of a straight line:
y - (-5) = 9(x - 0)
Then y + 5 = 9x, or
y = 9x - 5
