Answer:
I think -13 x and thanks for point
Answer:
x = 2, y = 5
Step-by-step explanation:
x + y = 7
2x - y = -1
3x = 6
x = 2
2 + y = 7
y = 5
Answer:
Step-by-step explanation:
Notice that x + 7 is a factor of the first two terms, and that it is also a factor of the last two terms. Thus,
x^3+7x^2-2x-14 = (x + 7)(x^2 - 2).
We could carry the factoring further, as follows:
(x + 7)(x^2 - 2) = (x + 7)(x - √2)(x + √2)
Answer: x = 3.05
Step-by-step explanation:
The picture shows the graphic solution using technology.
Verifying the approximate solution found on the graph.
x = 3.05
0.5x³ - 4 = 3x + 1
0.5(3.05)³ - 4 = 3(3.05) + 1
0.5*28.373 - 4 = 9.2 + 1
14.2 - 4 = 10.2
10.2 = 10.2 (ok)
