The customer bought 0.25 pounds of Sri Lankan coffee and 3.75 pounds of Kona coffee
Data;
Kona (y) = $6.20Sri Lankan (x) = $4.20System of EquationTo solve this question, let us write a system of equations to show this problem.
[tex]x + y = 4 ... equation (i)\\4.20x + 6.20y = 24.30... equation (ii)[/tex]
From equation (i)
[tex]x + y = 4\\x = 4 - y...equation (iii)[/tex]
Put equation (iii) into equation (ii)
[tex]4.20x + 6.20y = 24.30\\x = 4 - y\\4.20(4 - y)+ 6.20y = 24.30\\16.8 - 4.20y + 6.20y = 24.30\\16.8 +2y = 24.30\\2y = 24.30 - 16.80\\2y = 7.5\\2y/2 = 7.5/2\\y = 3.75[/tex]
Using the value of y which is the Kona's coffee, let's substitute this into equation (i) to solve for x
[tex]x+y = 4\\x = 4 - 3.75\\x = 0.25[/tex]
From the calculations above,
The amount of Sri Lankan coffee = 0.25 poundThe amount of Kona coffee = 3.75 poundsLearn more on system of equations here;

If the perimeter of the triangle is 32 centimeters, what is the length of each of the two sides?
A, B and C lie on a straight line.
Given that angle
y
= 128° and angle
z
= 91°, work out
x
.
Answer:
x = 37°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles .
y is an exterior angle of the triangle , then
y = x + z , that is
128° = x + 91° ( subtract 91° from both sides )
37° = x
Answer:
x+91+(180-y)=180
180-128=52
x+91+52=180
143+x=180
x=37

The multiplier for converting from micro to milli is.
Answer:
A fraction with value 1 that we use to convert quantities.
Step-by-step explanation:
1 micro = 0.001 milli 1 milli = 1000 micro
The prefix milli-, likewise, may be added to metre to indicate division by one thousand; one millimetre is equal to one thousandth of a metre. Decimal multiplicative prefixes have been a feature of all forms of the metric system, with six dating back to the system's introduction in the 1790s.

Find the inverse of each function.
1) y = log2 (3x)
2)y=log3(x-1)
3)y=-2log x
4)y=log6(3x)
5)y=log3(x+2)
6)y=log3(5^3)
7)y=6^x+5
9)y=log3 2^x
10)y=3^x -7
The inverse of a function is the opposite of the function
How to determine the inverse functions1) y = log2 (3x)
Swap the positions of x and y
[tex]x = \log_2(3y)[/tex]
Apply the exponential rule
[tex]2^x = 3y[/tex]
Make y the subject
[tex]y = \frac{2^x}3[/tex]
Hence, the inverse function is: [tex]y = \frac{2^x}3[/tex]
2) y=log3(x-1)
Swap x and y
[tex]x = \log_3(y - 1)[/tex]
Apply exponent rule
[tex]3^x = y - 1[/tex]
Make y the subject
[tex]y = 3^x + 1[/tex]
Hence, the inverse function is: [tex]y = 3^x + 1[/tex]
3) y=-2log x
Swap x and y
[tex]x=-2\log y[/tex]
Divide both sides by -2
[tex]-0.5x=\log y[/tex]
Apply exponent rule
[tex]y = 10^{-0.5x}[/tex]
Hence, the inverse function is: [tex]y = 10^{-0.5x}[/tex]
4) y=log6(3x)
Swap x and y
[tex]x = \log_6(3y)[/tex]
Apply exponent rule
[tex]3y = 6^x[/tex]
Make y the subject
[tex]y = \frac{6^x}{3}[/tex]
Hence, the inverse function is: [tex]y = \frac{6^x}{3}[/tex]
5)y=log3(x+2)
Swap x and y
[tex]x = \log_3(y + 2)[/tex]
Apply exponent rule
[tex]y + 2 = 3^x[/tex]
Make y the subject
[tex]y = 3^x - 2[/tex]
Hence, the inverse function is: [tex]y = 3^x - 2[/tex]
6) y=log3(5^3)
Swap x and y
[tex]x = \log_3(5^3)[/tex]
Hence, the inverse function is: [tex]x = \log_3(5^3)[/tex]
7) y=6^x+5
Swap x and y
[tex]x = 6^y + 5[/tex]
Subtract 5 from both sides
[tex]6^y = x - 5[/tex]
Apply logarithm
[tex]y = \log_6(x - 5)[/tex]
Hence, the inverse function is: [tex]y = \log_6(x - 5)[/tex]
9) y=log3 2^x
Swap x and y
[tex]x = \log_3(2^y)[/tex]
Apply exponent rule
[tex]2^y = 3^x[/tex]
Apply logarithm
[tex]y = \log_2(3^x)[/tex]
Hence, the inverse function is: [tex]y = \log_2(3^x)[/tex]
10) y=3^x -7
Swap x and y
[tex]x = 3^y - 7[/tex]
Add 7 to both sides
[tex]3^y = x + 7[/tex]
Apply logarithm
[tex]y = \log_3(x + 7)[/tex]
Hence, the inverse function is: [tex]y = \log_3(x + 7)[/tex]

You can use the given data and points to form equation of lines. And use them to find the slope(the constant of variation)
The function that has the greatest constant of variation is of function B
Option B: B
How to get the slope intercept form of a straight line equation?If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:
[tex]y = mx +c[/tex]
What is the equation of a line passing through two given points in 2 dimensional plane?Suppose the given points are [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] , then the equation of the straight line joining both two points is given by
[tex](y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)\\\\y = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1) + y_1\\\\y = \dfrac{y_2 - y_1}{x_2 - x_1}x + y_1 -\dfrac{y_2 - y_1}{x_2 - x_1}x_1[/tex]
Thus, comparing it with slope intercept form y = mx + c, we get
[tex]m = \dfrac{y_2 - y_1}{x_2 - x_1} = slope\\\\c = y_1 - \dfrac{y_2 - y_1}{x_2 - x_1}x_1[/tex]
Using the data given and the above facts to find the intended functionCalculating slope of all functions one by one
Function A:x = 8,9,10,11, and y = 20, 22.5, 25, 27.5
Two points (8,20), (9, 22.5) are enough.
The slope is
[tex]m =\dfrac{y_2 - y_1}{x_2 - x_1}= 2.5[/tex]
Function B:x = 1, 2, 3, 4 and y = 3.2, 6.4, 9.6, 12.8
Two points (1,3.2), (2,6.4) are enough.
The slope is
[tex]m = \dfrac{y_2 - y_1}{x_2 - x_1}= 3.2[/tex]
Function C:Two points are (0,0,), (3,1)
The slope is
[tex]m = \dfrac{y_2 - y_1}{x_2 - x_1}= \dfrac{1}{3}[/tex]
Function D:Two points are (0,0), (1,2)
The slope is
[tex]m= \dfrac{y_2 - y_1}{x_2 - x_1}= 2[/tex]
