Answer:
12/3=4
Step-by-step explanation:
it's 4, 2/3's stay the same. do the reciprocal on 1/6 which will be 6/1 and multiply
2/3(6/1)=12/3
and turn it to a mixed fractions and you would get 4

Help what is x??????
Answer:
-1
Step-by-step explanation:
-3x+8=11
= -8 -8
-3x=3
/-3 /-3
x= -1
Answer:
-1
Step-by-step explanation:
Subtract 8 so it cancel out, whatever you do to one side ode to the other. 11-8= 3 your left with -3x=3Divide -3 by -3 to cancel it out and leave x by itself. Whatever you do to one side do to the other. 3/-3= -1 your left with x= -1Hope this helped
find the domain of the graphed function -4-4 x is all real numbers
Domain and range:
The domain of a function is all the values the the input assumes.
The range of a function is given by all the values that the output assumes.
In a graphic:
The domain is given by the x-values, the horizontal axis.
The range is given by the y-values, the vertical axis.
In this question:
x, in the horizontal axis, assumes values between -4 and 2.
The closed circle at x = -4 and x = 2 indicates that these values are part of the interval.
Thus, the domain of the graphed function is: [tex]-4 \leq x \leq 2[/tex], and the correct answer is given by option D.
For more about domain and range of functions, you can check: https://brainly.com/question/21853810?referrer=searchResults
D. [tex]-4 \le x \le 2[/tex]
The procedure of solution consist consist in determine graphically the Domain of the Function shown in the figure. In this case, the Domain is the Set of values of [tex]x[/tex] in Interval notation, which represented in the "horizontal" axis of the Cartesian Plane. Please notice that black points means that given Function includes extreme values.
By visual examination of the function, we conclude that domain of the function is represented by:
[tex]Dom\{f(x)\} = [-4, 2][/tex]
Which is equivalent to the following expression in Inequality notation:
[tex]-4 \le x \le 2[/tex]
Therefore, we conclude that right answer is D.

Answer:
Every five minutes, the shuttle loses 1.6km in altitude. This can be written in the equation y = [tex]\frac{1.4}{-5}[/tex]x + 100.It would have been 100.56 km above the earth. You can do this by plugging in -2 into the equation above. You have to use -2 because it is 2 minutes before tracking started.It will take around 357 minutes for it to reach the ground. Set the equation equal to 0 and solve for x which represents the time taken.Step-by-step explanation:
1. change in y over change in x.
[tex]\frac{100-98.6}{0-5}[/tex] = [tex]\frac{1.4}{-5}[/tex]
This becomes your slope.
the y-intercept is 100 because at x = 0, y= 100.
So plug these values into y = mx + b and you get y = [tex]\frac{1.4}{-5}[/tex]x + 100.
2. If the line starts at x = 0, then if you want to get a value for 2 minutes prior you have to use -2 because 0 - 2 = -2.
y = [tex]\frac{1.4}{-5}[/tex](-2) + 100
Set it equal to zero and solve algebraically. The answer should be 100.56.
3. If we want to see how many minutes it takes to get to an altitude of 0, we have to make y = 0 and solve for x. This is because we know that y will be 0 but we don't know how long it takes.
0 = [tex]\frac{1.4}{-5}[/tex]x + 100
Solve algebraically and you should get an answer around 357.
If y varies directly as x and inversely as z and y = 4 when x = 2 and z = 7, find y when x =
6 and z = 3.
Answer:
y = 28
Step-by-step explanation:
Given that y varies directly as x and inversely as z then the equation relating them is
y = [tex]\frac{kx}{z}[/tex] ← k is the constant of variation
To find k use the condition y = 4 when x = 2 and z = 7, then
4 = [tex]\frac{2k}{7}[/tex] ( multiply both sides by 7 )
28 = 2k ( divide both sides by 2 )
14 = k
y = [tex]\frac{14x}{z}[/tex] ← equation of variation
When x = 6 and z = 3 , then
y = [tex]\frac{14(6)}{3}[/tex] = 14 × 2 = 28
A toll-free sales line sold 85 products for every 125 calls in one day. What is the daily success rate of the sales line? A. 0.125 B. 0.32 C. 0.68 D. 0.85
Answer:
C. 0.68
Step-by-step explanation:
Given;
number of products sold in a day by toll-free sales line = 85 products
number of calls in a day = 125
The daily success rate of the sales line is given by the ratio of the total products in a day to total number of calls in a day.
The daily success rate of the sales line = total products sold / number of calls
The daily success rate of the sales line = 85 / 125
The daily success rate of the sales line = 0.68
Therefore, the daily success rate of the sales line is 0.68

Answer the following:
21. Are the following equations parallel, perpendicular or neither?
-3x + y = -4
x + 3y = 6
Answer:
As the product of the slop of both lines is -1.
[tex]m_1\times m_2=-1[/tex][tex]3\times \frac{-1}{3}=-1[/tex]Therefore, the given equations are perpendicular.
Step-by-step explanation:
Given the equations
[tex]-3x+y=-4[/tex]
[tex]x+3y=6[/tex]
The slope-intercept form of the equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept.
Writing both equations in the slope-intercept form
[tex]-3x+y=-4[/tex]
[tex]y=3x-4[/tex]
So by comparing with the slope-intercept form we can observe that
slope of equation = 3
i.e.
[tex]m_1=3[/tex]
also
[tex]x + 3y = 6[/tex]
[tex]3y\:=\:6-x[/tex]
[tex]y=-\frac{1}{3}x+2[/tex]
So by comparing with the slope-intercept form we can observe that
the slope of equation = -1/3
i.e.
[tex]m_2=-\frac{1}{3}[/tex]
as
The slope of the perpendicular line is basically the negative reciprocal of the slope of the line.
so
The slope [tex]m_2[/tex] is the negative reciprocal of the slope [tex]\:m_1[/tex]
Also, the product of two perpendicular lines is -1.
i.e.
[tex]m_1\times m_2=-1[/tex]
VERIFICATION:
It is clear that the product of the slop of both lines is -1.
[tex]m_1\times m_2=-1[/tex]
[tex]3\times \frac{-1}{3}=-1[/tex]
Therefore, the given equations are perpendicular.

#weird percent thingy
#num1 is first number, num2 is is the percent (no decimal)
phrase=("number is percent of finder")
print (phrase)
num1=(1)
num2=(1)
result=(num1*100/num2)
print(result)
Answer:
12 is 20% of 60
28 is 35% of 80
84 is 42% of 200
32 is 80% of 40
35% of 60 is 21
25% of 132 is 33
5% of 40 is 2
15% of 20 is 3
Step-by-step explanation:
For the first 4 situations, you need to multiply the first number by the reciprocal of the percentage as a fraction, which would be 100/(percent). Here's an example:
12 is 20% of x
x = 12*(100/20)
100/20 was used because that is the reciprocal of 20/100, which is 20% as a fraction out of 100.
For the last 4 situations, you just need to multiply the number by the percentage as a decimal. For example:
35% of 60 is x
x = 60*.35
