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.
The answer would be (3,-1) because it is reflected
Answer:
B.76
Step-by-step explanation:
4 quarts = 1 gallon
so 4 * 19=76
Answer:
Step-by-step explanation:
L = 3x
w = 2x
Area = 294 ft^2
Formula
Area = L * w
Solution
Area = L * w Substitute into formula
294 - 3x * 2x Combine the right and switch
6x^2 = 294 Divide by 6
x^2 = 294/6
x^2 = 49 Take the square root of both sides
√x^2 = √49
x = 7
w = 2*7 = 2x = 14
L = 3*7 = 3x =21
