Find the value of x, 110°, 4x+2, and if you can help with steps that would be great :,)
Helen [10]

Answer:

x = 17

Step-by-step explanation:

The two angles with measures form a linear pair and are supplementary.

The measures of supplementary angles has a sum of 180°.

If you add the two given measures, the sum must equal 180°.

4x + 2 + 110 = 180

4x + 112 = 180

4x = 68

x = 68/4

x = 17

Find the number c that satisfies the conclusion of the Mean Value Theorem on the given interval. (Enter your answers as a comma-
ivanzaharov [21]

Answer:

c = \displaystyle\frac{9}{4}

Step-by-step explanation:

The following information is missing in the given question:

f(x) = \sqrt{x}

Using this we may solve the question as:

We are given the following in the question:

f(x) = \sqrt{x}, x \in [0,9]

We have to find the number c such that f(x) satisfies the Mean value theorem.

Mean Value theorem:

It states that if the function is differentiable in the closed interval [a,b], differentiable in the interval (a,b), then there exist c in (a,b) such that:

f'(c) = \displaystyle\frac{f(b)-f(a)}{b-a}

Now,

f(x) = \sqrt{x}\\f'(x) = \frac{1}{2\sqrt{x}}

Continuity in [0,9]

Since a polynomial function is continuous everywhere, f(x) is continuous in [0,9]

Differentiability in (0,9)

Since a polynomial function is differentiable everywhere the given function is differentiable in interval (0,9)

Then, by mean value theorem:

f'(c) = \displaystyle\frac{f(b)-f(a)}{b-a}\\\\\frac{1}{2\sqrt{c}} = \frac{f(9) - f(0)}{9-0} = \frac{3}{9}\\\\\frac{1}{2\sqrt{c}} = \frac{1}{3}\\\\c= \frac{9}{4}

Find the value of the variable, x
Vera_Pavlovna [14]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

2x + 3 = 45

Subtract sides 3

2x + 3 - 3 = 45 - 3

2x = 42

Divide sides by 2

\frac{2}{2} x =  \frac{42}{2}  \\

x = 21

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Thus the correct answer is the last option.
