Answer:

  x = -3 or 0

Step-by-step explanation:

Locate the horizontal line y = 5. Identify the x-values where the graph crosses that line. They are x = -3  and  x = 0.

Answer:

y=5/3x+5

Step-by-step explanation:

change slope in equation given to the negative reciprocal since the line is perpendicular:

-3/5 to 5/3

put values into point slope form y-y1=m(x-x1)

     y1 = y in the point given, which is 25

     m = slope, which is 5/3

     x1 = x in point given, which is 12

y-25=5/3(x-12)

then solve for slope intercept form y=mx+b to get

y=5/3x+5

14x - 9 + 8x + 3 = 9x - 8 - 3x - 14

Combine like terms:

14x + 8x - 9 + 3 = 9x - 3x - 8 - 14

22x - 6 = 6x - 22

Subtract 6x from both sides:

22x - 6x - 6 = 6x - 6x - 22

16x - 6 = -22

Add 6 to both sides:

16x - 6 + 6 = -22 + 6

16x = -16

Divide both sides by 16:

16x/16 = -16/16

x = -1. There is only one solution to this equation.

Answer:

Step-by-step explanation:

Here you go mate

Step 1

14x-9+8x+3=9x-8-3x-14  Equation/Question

Step 2

14x-9+8x+3=9x-8-3x-14  Simplify

22x-6=6x-22

Step 3

22x-6=6x-22  Subtract 6x from the sides

16x-6=-22

Step 4

16x-6=-22 Subtract -6

16x=-16

Step 5

16x=-16  Divide both sides by 16

-1

Answer:

The two triangles are related by AAS, so the triangles are congruent.

Step-by-step explanation:

Two angles and a non-included side of one triangle are congruent to corresponding two angles and an included side in the other triangle. Therefore, we can conclude that the two triangles are related by the AAS Congruence Criterion. Hence, both triangles congruent to each other.

Answer:

Step-by-step explanation:

3(1)^2 = 3

3(2)^2 = 12

3(3)^2 = 27

3(10)^2 = 300

ln(40) + 2ln(1/2) + ln(x)

First, you should take the 2 and put it back in the argument. Since it's a coefficient, when you put it back it in would be a power. That changes 2ln(1/2) to ln(1/2 ^ 2), which is ln(1/4).

ln(40) + ln(1/4) + ln(x)

Then, to add these, we just multiply the arguments, meaning we just have:

ln(40 * 1/4 * x)

Multiply and then we're done.

ln(10x)

Using logarithmic function, the condense of Ln 40 + 2 ln 1/2 + ln x is ln(10x).

Logarithmic function is function is an " inverse of an exponential function so that the independent variable appears logarithmic function".

According to question,

Ln 40 + 2 ln 1/2 + ln x

Properties of Logarithmic function     [tex]x ln (a) = ln(a^x)[/tex].

Using above properties we can write [tex]2 ln \frac{1}{2}[/tex] [tex]= ln(a^(\frac{1}{2})^2)[/tex] [tex]=ln(a^\frac{1}{4})[/tex].

Properties of Logarithmic function [tex]ln(a) + ln(b) = ln(ab)[/tex]

Using above properties we can write Ln 40 + 2 ln 1/2 + ln x as [tex]ln(40 . \frac{1}{4}.x)[/tex].

= [tex]ln(10x)[/tex]

Hence, Using logarithmic function, the condense of Ln 40 + 2 ln 1/2 + ln x is ln(10x).

Answer:

10%

Step-by-step explanation:

According to the scenario, given data are as follows:

Students over age 21 = 30

Students under age 21 = 20

Choose student over age 21 = 3

Choose student under age 21 = 2

So, we can calculate chances by using following method,

Chances of student over age 21 = Number of choose student ÷ Total students

= 3 ÷ 30  = 0.10 = 10%

Similarly, Chances of student under age 21 = Number of choose student ÷ Total students

= 2 ÷ 20  = 0.10 = 10%

Hence, in both condition, chances are 10%.

Answer:

the amount that nearest to the paper cost with the discount but before tax is $12.83

Step-by-step explanation:

The computation of the amount that nearest to the paper cost with the discount but before tax is shown below:

= Cost of a photo paper - discount

= $13.50  - 5% of $13.50

= $13.50 - $0.675

= $12.83

Hence, the amount that nearest to the paper cost with the discount but before tax is $12.83

Answer:

Yes

Step-by-step explanation:

Given that :

CHAIN A:

Sample size n1 = 30

Sample standard deviation of waiting time s1 = 21.2

CHAIN B:

Sample size, n2 = 28

Sample standard deviation of waiting time s2 = 31.4

Null hypothesis H0: s1 = s2

Alternative hypothesis H1: s1 < s2

Test statistic ; Ftest : s1² / s2²

Ftest = 21.2^2 / 31.4^2

= 0.4558399

P value from F statistic : = 0.02 (using p value calculator)

Since the pval < 0.05

Then we reject the Null ; Chain A waiting time is more consistent

The factorised form of given function f(x) is (x + 2)(x +√3)(x-√3) which is correct answer would be option (B).

A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.

We have been given the polynomial function:

⇒ x³ + 2x² - 3x -6

Simplify the radical by breaking the radicand up into a product of known factors.

⇒ x³ + 2x² - 3x -6

Add and subtract the second term to the expression and factor by grouping.

⇒ x²(x + 2) - 3(x + 2)

⇒ (x + 2)(x² - 3)

⇒ (x + 2)(x +√3)(x-√3)

Therefore, the factorised form of given function f(x) is (x + 2)(x +√3)(x-√3).
