What is linear equation?A two-variable equation with a line-shaped graph is referred to as a linear equation. A collection of coordinate plane points that are all the solutions to the linear equation make up the graph. If all of the variables have true numerical values, the equation can be graphed by first drawing a sufficient number of points to identify a pattern, then connecting those points to include all of the points.
A linear equation is represented in standard form as
Ax+By=C,A,B≠0
The equation for y must first be solved before you may graph a linear equation in its usual form.
The x-intercept is found by finding the value of x when y = 0, (x, 0), and the y-intercept is found by finding the value of y when x = 0, (0, y).

The equation of line r is x = -3/2y + 5/2.
What is the equation of the line?A line's equation is typically expressed in the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. A line's equation expresses the y coordinate of any point on the line in terms of its x coordinate. In other terms, a line equation is a formula that can be used to compute the y coordinate of any point on a line given its x coordinate.
In the given question,
The equation of line r is y = -1/3x + 7.
Line r is perpendicular to line q, so the slopes of the two lines must be opposite reciprocals of one another. The slope of line q is 3, so the slope of line r must be -1/3.
To find the equation of line r, we can use the point-slope formula. The point-slope formula is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.
In line r, (x1, y1) is (1, 3). The slope, m, is -1/3.
Substituting values into the point-slope formula, we have y - 3 = -1/3(x - 1).
Solving for y, we have y = -1/3x + 7.
This equation is written in slope-intercept form, which is the form y = mx + b, where m is the slope and b is the y-intercept.
In line r, the slope is -1/3 and the y-intercept is 7.

The estimated quantity of dye left in a healthy pancreas 30 minutes after the injection, rounded to the closest hundredth of a grams, is 0.07 grams.
As per the question given,
After the dye is injected, a healthy pancreas will secrete 4% of the remaining amount of dye each minute. Let's use exponential decay to model the amount of dye remaining in the pancreas over time.
The amount of dye remaining after t minutes can be expressed as:
R(t) = 0.3 * (1 - 0.04)^t
We want to find the amount of dye remaining after 30 minutes, so we can substitute t=30 into the equation and calculate:

Terrell decides to buy some strawberry jam for his grandmother at the Berrien County Farmer's Market. The jars are cylinders.
Terrel has enough money to either
buy one large jar has which has a diameter of 8 cm, and a height of 16 cm.
or
buy three small jars of jam which have a diameter of 6 cm, a height of 7 cm.
Which option will give him the most jam to give to his grandmother? Please explain your answer and your reasoning in complete sentences. Be sure to explain each step that requires a computation. Use key vocabulary like "volume of a cylinder."
Answer:
A large container is a better deal because for a large container the amount of jam per dollar is greater thank that in the three smaller containers.
Step-by-step explanation:
What is the volume of a cylinder?
The volume of a cylinder is given by -
V[c] = πr²h
Given is Terrel who has to buy either one large jar or three small jars of jam. A small jar has a diameter of 6 cm, a height of 7 cm, and costs $4. A large jar has a diameter of 8 cm, a height of 16 cm, and costs $12.
For one large container, its volume will be -
V[L] = πr²h = 22/7 x 4 x 4 x 16 = 804.56 cm³
Amount of jam per dollar = V[1] = 804.56 / 12 = 67.04 cm³
For three small containers, the total volume will be -
V[S] = πr²h = {22/7 x 3 x 3 x 7} x 3 = 594 cm³
Amount of jam per dollar = V[2] = 594 / 12 = 49.5 cm³
It can be seen that for a large container the amount of jam per dollar is greater than that in the three small container. Hence, a big container would be a better deal for Terrell.
Therefore, a large container is a better deal because for a large container the amount of jam per dollar is greater than that in the three small container.

Step-by-step explanation:
To solve the inequality 4x-(6x+1)≤ 8x + 2(x-3), we can simplify both sides of the inequality and isolate x on one side:
4x - (6x + 1) ≤ 8x + 2(x-3)
4x - 6x - 1 ≤ 8x + 2x - 6
-2x - 1 ≤ 10x - 6
Subtract 10x from both sides:
-12x - 1 ≤ -6
Add 12x to both sides:
-1 ≤ 6x
Divide both sides by 6:
-1/6 ≤ x
The solution to the inequality is x ≥ -1/6. This means that x is greater than or equal to -1/6, so any value of x that is greater than or equal to -1/6 will satisfy the inequality.

Answer: Y would be 4
If you look at the graph and find 7 on the x axis where the inputs are, you can see that if you go up, the only output for 7 is 4.
Find the constant of proportionality (r)(r)left parenthesis, r, right parenthesis in the equation y=rxy=rxy, equals, r, x
The constant of proportionality (r) in the equation y = rx represents the rate of change of y with respect to x, indicating the factor by which x and y are related.
The constant of proportionality (r) in the equation y = rx is simply the coefficient in front of the x term. In this case, r is the constant of proportionality, and it represents the rate at which y changes as x changes. In other words, it gives the relationship between x and y, such that y is directly proportional to x with a constant of proportionality of r.
So, in the equation y = rx, the value of r is the constant of proportionality.
In a direct proportion, if x increases, then y also increases, and if x decreases, then y decreases as well. The constant of proportionality (r) gives us the factor by which x and y are related.
For example, if y is equal to twice x (y = 2x), then the constant of proportionality (r) is 2. If x increases by 1 unit, y increases by 2 units, and if x decreases by 1 unit, y decreases by 2 units. The constant of proportionality in this case is 2.
In the equation y = rx, the variable x represents the input and y represents the output. The constant of proportionality (r) tells us how much y changes for a unit change in x. It can be thought of as the ratio of the change in y to the change in x. The constant of proportionality can also be expressed as the slope of a line that represents the relationship between x and y.
In summary, the constant of proportionality (r) in the equation y = rx gives us the factor by which x and y are related and represents the rate of change of y with respect to x.

how many 3-digit numbers have exactly one zero?
Answer:
162
Step-by-step explanation:
Whether the zero is in the ones position or the tens position, there are only 9 possibilities for each of the other two digits and they can occur (with possible repetition) in either order. That’s 81 for each zero position for a total of 162.
There are 171 three-digit numbers that have exactly one zero. The zero can be in either the tens or units places, yielding 90 and 81 possibilities respectively.
Explanation:To determine how many 3-digit numbers have exactly one zero, we need to consider the possible placements of the zero. A 3-digit number has three positions: the hundreds place, tens place, and units place. The zero cannot be in the hundreds place, as that would make it a 2-digit number. So, the zero can only have two possible positions: the tens or units place.
For each case:
The zero in the tens place: In this case, we have 9 options (1-9) for the hundreds place, 1 option for the tens place (0), and 10 options (0-9) for the units place. This gives 9 * 1 * 10 = 90 numbers.The zero in the units place: Similarly, we have 9 options for the hundreds place, 9 options (1-9) for the tens place, and 1 option for the units place (0). This gives 9 * 9 * 1 = 81 numbers.So, in total, we have 90 + 81 = 171 3-digit numbers with exactly one zero.
