X + 7 > 0 , x > -7
2x -5 > 0 , 2x > 5 , x > 2.5
since that if x is more than 2.5 ,it will be more than -7
so the correct answer is x > 2.5

Short Answer D
The point here is that the angle on the left (64o) produces a longer base line than the angle (35o) on the right. That means you need to set up your inequality to reflect that. It's a neat, but tricky question.

x + 7 > 2x - 5 Add 5 to both sides.
5 + 7 + x > 2x
12 + x > 2x Subtract x from both sides.
12 > 2x - x
12 > x

The minimum distance is when the thirty five degree angle becomes 0.
The distance cannot be less than 0, however.

2x - 5>0
2x > 5
x > 5/2
x > 2.5

So the correct answer to this is
2.5<x< 12

The answer is the 4th one down or D

What is the measure of AC

Amiraneli [1.4K]

Angle ABC is an inscribed angle so would be half of the arc.
So, 4x-5.5=1/2(5x+25)
4x-5.5=5/2x+25/2
4x-5.5=2.5x+12.5
4x-2.5x=12.5+5.5
1.5x=18
x=12

So angle ABC=4(12)-5.5=48-5.5=42.5
Arc AC=5(12)+25=60+25=85

Check: 42.5(2)=85

Answer: Arc AC is 85

What is the reason for statement 3 in this proof?

const2013 [10]

Answer:

A. Definition of angle bisector

Step-by-step explanation:

Given that ΔABC is an isosceles triangle where AB = BC, and that BD bisects ∠ABC, then by the definition of angle bisection of ∠ABC, we have;

m∠ABD = m∠CBD

The correct option is option A. Definition of angle bisector

Also, given that ΔABC is an isosceles triangle and BD is the angle bisector of ∠ABC, we get;

AD = CD and BD = BD

We can therefore, also find that ΔABD ≅ ΔCBD by Side Side Side (SSS) rule of congruency

First integral:

Use the rational exponent to represent roots. You have

$\displaystyle \int\sqrt[8]{x^9}\;dx = \int x^{\frac{9}{8}}\;dx$

And from here you can use the rule

$\displaystyle \int x^n\;dx=\dfrac{x^{n+1}}{n+1}+C$

to derive

$\displaystyle \int\sqrt[8]{x^9}\;dx = \dfrac{x^{\frac{17}{8}}}{\frac{17}{8}}=\dfrac{8x^{\frac{17}{8}}}{17}$

Second integral:

Simply split the fraction:

$\dfrac{3+\sqrt{x}+x}{x}=\dfrac{3}{x}+\dfrac{\sqrt{x}}{x}+\dfrac{x}{x}=\dfrac{3}{x}+\dfrac{1}{\sqrt{x}}+1$

So, the integral of the sum becomes the sum of three immediate integrals:

$\displaystyle \int \dfrac{3}{x}\;dx = 3\log(|x|)+C$

$\displaystyle \int \dfrac{1}{\sqrt{x}}\;dx = \int x^{-\frac{1}{2}}\;dx = 2\sqrt{x}+C$

$\displaystyle \int 1\;dx = x+C$

So, the answer is the sum of the three pieces:

$3\log(|x|) + 2\sqrt{x} + x+C$

Third integral:

Again, you can split the integral of the sum in the sum of the integrals. The antiderivative of the cosine is the sine, because $\sin'(x)=\cos(x)$ . So, you have

$\displaystyle \int \left( \cos(x)+\dfrac{1}{7}x\right)\;dx = \int \cos(x)\;dx + \dfrac{1}{7}\int x\;dx = \sin(x)+\frac{1}{14}x^2+C$

How do you model function using rules tables and graphs?

Oksana_A [137]

Answer:

For X and then determine Y. So when X is equal to negative 2. Notice that Y is going to be equal to negative 2 times negative 2 plus 5. Well negative 2 times negative 2 is 4 4 plus 5 equals 9.
