Answer:
4th option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, 0 ) and (x₂, y₂ ) = (0, - 9) ← 2 points on the line
m = [tex]\frac{-9-0}{0-(-6)}[/tex] = [tex]\frac{-9}{0+6}[/tex] = [tex]\frac{-9}{6}[/tex] = - [tex]\frac{3}{2}[/tex]
The line crosses the y- axis at (0, - 9 ) ⇒ c = - 9
y = - [tex]\frac{3}{2}[/tex] x - 9 ← in slope- intercept form
Multiply through by 2 to clear the fraction
2y = - 3x - 18 ( add 3x to both sides )
3x + 2y = - 18 ← in standard form
6+8/2 I need help on this
Answer:
10
Step-by-step explanation:
1. Any number has a denominator of 1 so you have 6/1 and 8/2.
2. To add you need to make the denominators the same so multiply the 2 to the numerator and denominator of 6/1 which makes 12/2.
3. 12/2+8/2 is 20/2.
4. Simplify 20/2 by dividing the top and bottom by 2 to get 10/1.

Answer:
1 is equal
2 is greater
3 is greater
Step-by-step explanation:
2^3 x 2^5 is 32, and 2^5 is 32, meaning these are equal.
2^2 x 3^2 is 36, and 6^3 is 216, meaning 6^3 is greater.
2^3 x 3^2 is 72, and 6^2 is 36, meaning that 2^3 x 3^2 is greater.

g(x) = x^2 + 2g(x)= x^2 + 2
What is the value of f(g(-2))?
Answer:
Answer is 12
Step-by-step explanation:
f(g(-2))
=f((-2)^2+2)
=f(6)

Given that AABC ADEF, find the length of side DF Show the equation and ALL algebra used to solve for the length of DE
Answer:
the length of side DF is 19
Step-by-step explanation:
you first need to find what x=
sides AB=DF AC=DE BC=FE
so we can say that 3x+1=19
3x+1=19
-1 -1
3x=18
÷ by 3
x=6
then DF os 2x+7
so 2(6)+7
12+7=19

the linear functions f(x) and g(x) are represented on the graph where g(x) is a transformation
Part A: Describe two types of transformations that can be used to transform f(x) to g(x). (2 points)
Part B: Solve for k in each type of transformation. (4 points)
Part C:
an equation for each type of transformation that can be used to transform f(x) to g(x). (4 points)
Answer/Step-by-step explanation:
Given :
The linear functions f(x) and g(x) are represented on the graph, where g(x) is a transformation of f(x):
To Find: two types of transformations that can be used to transform f(x) to g(x).
=================================================================
Part A: Describe two types of transformations that can be used to transform f(x) to g(x). (2 points)
Solution Part A:
f(x) = x/5 + y/(-10) = 1
=> 2x - y = 10
=================================================================
Part B: Solve for k in each type of transformation. (4 points)
Solution Part B:
g(x) = x/(-3) + y/6 = 1
=> 2x - y = - 6
=================================================================
an equation for each type of transformation that can be used to transform f(x) to g(x). (4 points)
Solution Part C:
Transformations :
g(x) = f(x) + 16
g(x) = f(x + 8)
The length of a 10-minute video is decreased by 45% when the video is edited. What is the length of the edited video?
Answer:
The edited video would now be 5 Minutes 50 Seconds
Step-by-step explanation:
10-4.5=5.5
To subtract any percentage from a number, simply multiply that number by the percentage you want to remain. In other words, multiply by 100 percent minus the percentage you want to subtract, in decimal form. To subtract 20 percent, multiply by 80 percent (0.8).
Step-by-step explanation:
its 5.5 mins
here are the methods
1-0.45= 0.55 0.55*10= 5.5
or
its
45/100= 0.45 0.45*10min= 4.5 10mins-4.5mins= 5.5 mins

(d)
3gh² × 4g³h³

A formula used for calculating velocity is v=1/2at^2 what is a expressed in terms of v and t
Answer:
[tex]v = \frac{1}{2} a {t}^{2} \\ a = \frac{2v}{ {t}^{2} } [/tex]
'a' can be expressed in terms of 'v' and 't' as -
[tex]$a=\frac{2v}{t^{2} }[/tex]
We have the following expression -
[tex]$v = \frac{1}{2} at^{2}[/tex]
We have to express → a in terms of v and t.
What is the value of x in -Sin([tex]2n\pi x[/tex]) = 0.785?On solving, we get -
Sin([tex]2n\pi x[/tex]) = 0.785
Sin([tex]2n\pi x[/tex]) = Sin ([tex]\frac{\pi }{4}[/tex])
2n[tex]\pi[/tex]x = [tex]\frac{\pi }{4}[/tex]
x = [tex]$\frac{1}{8n}[/tex]
According to the question, we have -
[tex]$v = \frac{1}{2} at^{2}[/tex]
[tex]$a=\frac{2v}{t^{2} }[/tex]
Hence, 'a' can be expressed in terms of 'v' and 't' as -
[tex]$a=\frac{2v}{t^{2} }[/tex]

A cross-sectional is a research that is carried out by collecting data from different group of population or by drawing a random sample from a group of population in which the researcher will then study or observe the data collected at a particular period of time.
Based on the given information the researcher is making use of Cross-sectional research method as the researcher what to know how people perceive smell based on their age or how age determine people sense of smell.
The outcome that could be found based on the research is that as people age or grow older their sense of smell decrease or begins to decrease, which simply means that younger people have strongest sense of smell than older people.
