Solve for x:<br> 3x + 2x + 7 = 10x - 16<br> What’s the answer ?
Veseljchak [2.6K]

Answer:

x=\frac{23}{6} or 4.6

Step-by-step explanation:

3x + 2x + 7 = 10x - 16

5x+7=10x-16

Subtract 7 from both sides:

5x+7-7=10x-16-7\\5x=10x-23

Subtract 10x from both sides:

5x-10x=10x-23-10x\\-5x=-23

Divide both sides by -5:

\frac{-5x}{-5}=\frac{-23}{-5}\\x=\frac{23}{5} or 4.6

Show that the equation x^3+6x-5=0 has a solution between x=0 and x=1
Mnenie [13.5K]

Answer:

Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.

Step-by-step explanation:

The equation f(x) given is:

f(x) = x^3+6x-5

For x = 0. the value of the expression is:

f(0) = 0^3+0-5\\f(0) = -5

For x = 1, the value of the expression is:

f(1) = 1^3+6-5\\f(1)=2

Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.

In other words, there is at least one solution for the equation between x=0 and x=1.
