Step-by-step explanation:
Given Equation:
[tex]7x-3y=11[/tex]Required:
Solve the equation for [tex]y[/tex].Find ordered pairs.Steps:
Subtract 7x from both sides of the equation.
-3y = 11 - 7x
Divide each term in -3y = 11 - 7x by -3 and simplify.
-3y/-3 = 11/-3 + -7x/-3
Simplify the left side.
Cancel the common factor of -3.
-3y/-3 (canceled) = 11/-3 + -7x/-3
Divide y by 1.
y = 11/-3 + -7x/-3
Simplify the right side.
Simplify each term.
Move the negative in front of the fraction.
y = -11/3 + -7x/-3
Dividing two negative values results in a positive value.
y = -11/3 + 7x/3
Choose any value for x that is in the domain to plug in to the equation.
Choose 0 to substitute in for x to find the ordered pair.
Remove parentheses.
y = -11/3 + 7(0)/3
Simplify -11/3 + 7(0)/3.
⇒ Combine the numerators over the common denominator.
y = -11/3 + 7(0) / 3
Simplify the expression.
Multiply 7 by 0.y = -11 + 0/3
Add -11 and 0.y = -11/3
Move the negative in front of the fraction.y = -11/3
Use the x and y values to form the ordered pair.
(0, -11/3)
Choose 1 to substitute in for x to find the ordered pair.
Remove parentheses.
y = -11/3 + 7(1)/3
Simplify -11/3 + 7(1)/3.
Combine the numerators over the common denominator.
y = -11/3 + 7(1)/3
Simplify the expression.
Multiply 7 by 1.
y = -11 + 7/3
Add -11 and 7.
y = -4/3
Move the negative in front of the fraction.
y = -4/3
Use the x and y values to form the ordered pair.
(1, -4/3)
Choose 2 to substitute in for the x in the ordered pair.
Remove parentheses.
y = -11/3 + 7(2)/3
Simplify -11/3 + 7(2)/3.
Combine the numerators over the common denominator.
y = -11/3 + 7(2)/3
Simplify the expression.
Multiply 7 by 2.
y = -11 + 14/3
Add -11 and 14.
y = 3/3
Divide 3 by 3,
y = 1
Use the x and y values to form the ordered pair.
(2, 1)

48% of people in a certain country like to cook and 54% of people in the country like to shop, while 26% enjoy both activities. What is the probability that a randomly selected person in the country enjoys cooking or shopping or both? The probability that a randomly selected person in the country enjoys cooking or shopping or both is ________
The probability that a randomly selected person in the country enjoys cooking or shopping or both will be;
⇒ P (C ∪ S) = 0.76
What is mean by Probability?
The term probability refers to the likelihood of an event occurring.
Given that;
48% of people in a certain country like to cook.
And, 54% of people in the country like to shop, while 26% enjoy both activities.
Now,
Probability to like the cook P (C) = 48%
Probability to like the shop P (S) = 54%
Probability to like the both activity P (C∩S) = 26%
So, Probability to like the both activity P (C ∪ S) is calculated as;
P (C ∪ S) = P (C) + P (S) - P (C ∩ S)
P (C ∪ S) = 48% + 54% - 26%
P (C ∪ S) = 102% - 26%
P (C ∪ S) = 76%
P (C ∪ S) = 0.76
Thus, The probability that a randomly selected person in the country enjoys cooking or shopping or both will be;
⇒ P (C ∪ S) = 0.76

Explanation:
To complete the missing values, we have to evaluate the function at the x-values given.
For example, to find the number below x = -1, we will put in x = -1 into y = (1/6)^x.
Putting in x = - 1 in y = (1/6)^x gives
[tex]y=(\frac{1}{6})^{-1}[/tex]which simplifies to give
[tex]y=\frac{1}{1/6}[/tex][tex]\rightarrow y=6[/tex]Similarly, for the missing value below x = -2, we put in x = - 2 into y = (1/6)^x to get
[tex]y=(\frac{1}{6})^{-2}[/tex]which simplifies to give
[tex]y=\frac{1}{(1/6)^2}[/tex][tex]\begin{gathered} \rightarrow y=6^2 \\ \rightarrow y=36 \end{gathered}[/tex]Similarly, for the missing value below x = 2, we put in x = 2 in y = (1/6)^x to get
[tex]y=(\frac{1}{6})^2[/tex]which simplifies to give
[tex]y=\frac{1}{36}[/tex]Hence, the missing value to be put in is 36.

A linear function r models the growth of your right index fingernail. The length of the fingernail increases 0.7 millimeter every week. Graph r when r(0)=12.
A nail's length in x weeks of m=0.7 slope with a growth rate of mm per week b starting length follows.
The slope-intercept form of a straight-line equation is indicated by y = mx + b. X and y denote the line's distance from the x- and y-axes, respectively. When x = 0, the value of b equals y, and m indicates how steep the line is.
Given, r(0) = 12
According to the question, fingernail increases by 0.7 millimeters every week. So, m = 0.7 which is the slope of the equation of a straight line.
r(0) = 12 is the b of the y = mx + b.
Now, the final equation is:
r(x) = 0.7x + 12
As a result, the slope of r(x) length of a nail in x number of weeks of m=0.7, with growth rate in mm per week b starting length.

The equation of the line passing through the points: (3,-10.5) and (1,-7.5) is [tex]3x+2y+12=0.[/tex]
How to find equation of a line by two-point form?Every point on a line fulfills the equation of that line, which means that every point on the line represents every other point on the line.
The equation of a line passing through two-points [tex](x_{1} ,y_{1} )[/tex] and [tex](y_{1} ,y_{2} )[/tex] is given by the formula,
[tex]y-y_1= \frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
So, the equation of the line passing through the points (3,-10.5) and (1,-7.5) will be-
⇒[tex]y-(-10.5)=\frac{-7.5-(-10.5)}{1-3} *(x-3)[/tex]
⇒[tex]y+10.5=\frac{-7.5+10.5}{-2} *(x-3)[/tex]
⇒[tex]y+10.5=\frac{3}{-2} *(x-3)[/tex]
⇒[tex]y+10.5=\frac{-3x}{2} +\frac{9}{2}[/tex]
⇒[tex](y+10.5)*2=-3x+9[/tex]
⇒[tex]2y+21=-3x+9[/tex]
⇒[tex]2y+3x+21-9=0[/tex]
⇒[tex]3x+2y+12=0[/tex]
Hence, the equation of the line passing through the points (3,-10.5) and (1,-7.5) is [tex]3x+2y+12 =0[/tex].

The weights (in pounds) of the gaskets in a batch are 0.58, 0.63, 0.65, 0.53, and 0.61. Which gaskets should be thrown out? Use an absolute value inequality to justify your answer.
If the weights (in pounds) of the gaskets in a batch are 0.58, 0.63, 0.65, 0.53, and 0.61. The gaskets that should be thrown out is 0.53 and the inequality is: 0.54 ≤ w ≤ 0.66.
Means and inequalityUsing this formula to determine the mean
Mean = ∑x/n
Mean = 0.58 + 0.63 + 0.65 + 0.53 + 0.61 /5
Mean = 3/6
Mean = 0.6
Since the mean is 0.6 the gasket that are less than 0.53 and more than 0.66 (0.6±0.06) should be thrown out which in turn means that 0.53 should be thrown out.

Description of the function over each part of its domain is:
Slope = 0 and the domain is constant at (0,12000).Domain (12000, 38000) is declining with a negative slope.What is a function?A function is a type of rule that produces one output for a single input. This is illustrated by the equation y=x2. Any input for x results in a single output for y. Considering that x is the input value, we would say that y is a function of x.So, we examine the displayed graph.
The y values are constant from x = 0 to x = 12,000.
There is no increase or decrease in y's value; it is constant.Consequently, the graph's cost is constant from x=0 to x=12000.So slope = 0.
Then,
Slope = 0 and the domain is constant at (0,12000).
The y values are decreasing from x = 12,000 to x = 38,000.The slope is negative for y values that are decreasing.The slope is therefore negative.Domain (12000, 38000) is declining with a negative slope.
