You haven't shared "the given value of x," or, if you have, you haven't drawn attention to it.
Just suppose we were to choose x = 4 as a possible solution and then try to find a value of the parameter k that would make x = 4 an actual solution.
2(4) + 4k - 9 = (4)(4) - (4) + 1
Then 8 + 4k - 9 = 16 - 4 + 1, or 4k - 1 = 13. Then 4k = 14, and k = 14/4, or (after reduction) k = 7/2
If the parameter k equals 7/2, then x = 4 is a solution to the given equation.
To check this out further, start with the proposed solution x = 5 and find k.
Answer:
Step-by-step explanation:
y = 5x - 43.....slope is 5
a parallel line will have the same slope
(-6,0)...x = -6 and y = 0
slope(m) = 5
y = mx + b
0 = 5(-6) + b
0 = -30 + b
30 = b
so ur parallel equation is : y = 5x + 30
Answer:
20%
Step-by-step explanation:
1000/1250=0.8
1000 is 80% of the original price
therefore the percentage loss is 20%
Answer: D
Step-by-step explanation:
A quadratic function has a degree of 2 so there will be two roots. The statement says the function does NOT CROSS THE X-AXIS so there are no real roots. That means both roots must be imaginary (complex).
