Determine the unknown angle measures?
Answer:
Step-by-step explanation:
A certain data set has a line-of-best-fit that travels through these two points: (6, 275) and (8, 450) write the equation for that line-of-best-fit.
The equation of the line is - 175 x + 2 y = - 500
From the question, we have
Point 1 :
x-coordinate, x1 = 6
y-coordinate, y1 = 275
Point 2 :
x-coordinate, x2 = 8
y-coordinate, y2 = 450
We know that,
y-275 = (275-450)/(6-8)*(x-6)
y-275 = 175/2*(x-6)
- 175 x + 2 y = - 500
Slope of a Line :
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
As a result, m = change in y/change in x = y/x is the formula for the change in y-coordinate with respect to the change in x-coordinate.
where "m" represents a line's slope.
The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.

-j + 0.8 = -0.9j + 0.76
What is the answer :D
Answer:
j = 0.4
Step-by-step explanation:
hope it helps
To answer this question, you should combine like terms:
Like terms are two or more terms that share the same variable.
J is the variable in this question so add 0.9j to both sides of the equation to get j on one side:
-0.1j + 0.8 = 0.76
Now subtract 0.8 from both sides to isolate j on one side of the equation:
-0.1j = -0.04
Divide both sides by -0.1 to isolate j and your answer should be:

What are examples of linear equations?
An equation with only one variable is referred to as a linear equation in one variable. It has the mathematical formula Ax + B = 0, where A and B can be any two real numbers, and x is an unknowable variable with just one possible value. One such linear equation in one variable is 9x + 78 = 18.Step 1 - Write the equation.
3/a + 2 - 6a/a² - 4 = 1/a - 2
Step 2 - rewrite the equation.
3/a + 2 - 6a/a² - 4 = 1/a - 2
Step 3 - Take the LCM.
3(a- 2) - ( a + 2 )/a² - 2² = 6a/a²-4
Step 4 - Further simplify the above expression
3a - 6 - a - 2/a² - 4 = 6a/a² - 4
Step 5 - Cancel out the denominator of both sides and then further simplify.

1 is the value of cat in linear equation.
What is an explanation of a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.number of cats = n
number of fleas per cat = 2n
total number of fleas = (number of fleas per cat) * (number of cats) = 2n * n = 2n2
If we take the total number of fleas, subtract the fleas of two cats, then subtract 3 for every remaining cat, we get half the total number of fleas.
(total number of fleas) - 2(number of fleas per cat) - 3(n - 2) = (total number of fleas)/2
2n2 - 2(2n) - 3(n - 2) = (2n2)/2
2n2 - 4n - 3n + 6 = n2
Subtract n2 from both sides and combine like terms.
n2 - 7n + 6 = 0
Factor the left side
(n - 6)(n - 1) = 0
n = 6 or n = 1
n must be 6 because we can't remove 2 cats if there is only 1 cat to begin with.

Answer: 422.39
Step-by-step explanation:
To find the shaded region (I'm assuming it's the area inside the circle but outside the rectangle), subtract the area of the rectangle from the area of the circle.
The formula for circle area: πr^2
r is the radius, and it is given that r = 12, so the area of the circle is:
π * 12^2 ---> 144π is the area of the circle
Next, find the area of the rectangle: 3 * 10 = 30
Finally, find subtract the area of the rectangle from the area of the circle to find the shaded region:
144π - 30 ≈ 422.39

What is the price per gallon at Miguel's Gasoline Station?
Responses
$2.50
Based on the line on the graph, the price per gallon at Miguel's Gasoline Station is equal to: B. $2.50
How to calculate the price per gallon?In order to calculate the price per gallon at Miguel's Gasoline Station, we would have to determine the slope of the line representing the number of gallons bought and the total cost of their purchases are plotted on the graph below (see attachment).
Mathematically, the slope of any straight line can be calculated by using this formula;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
By critically observing the graph (see attachment), we can logically deduce that the line passes through the following points:
Points (x, y) = (4, 10)Points (x, y) = (8, 20)Substituting the given parameters into the formula, we have;
Slope, m = (20 - 10)/(8 - 4)
Slope, m = 10/4
Slope, m = 2.5

The length and width of a rectangle are consecutive integers. The perimeter of the rectangle is 54 centimeters. Find the length and width of the rectangle.
Thank you!
Answer:
length = 13 cm and width = 14 cm
Step-by-step explanation:
let n be the length then n + 1 is the width
the perimeter (P) of a rectangle is calculated as
P 2(l + w) ← l is length and w is width
given P = 54 , then
2(n + n + 1) = 54 ( divide both sides by 2 )
2n + 1 = 27 ( subtract 1 from both sides )
2n = 26 ( divide both sides by 2 )
n = 13
n + 1 = 13 + 1 = 14
length = 13 cm and width = 14 cm

Plan B: No per month charge,but a charge of 0.10 per text. Is there a certain number of texts,when the two plans cost the same amount? Determine your answer by setting up a system of equations that model the two plans.
The system of equation for the given condition is: 5+0.03x = 0.10x, where x is the number of texts.
There is no certain number of texts for which two plans are equal.
Let the number of texts for which two plans amount to same number be = x
Plan A: $5.00 per month charge along with a charge of $0.03 per text.
So, Plan A: 5+0.03x
Plan B: No per month charge but a charge of 0.10 per text.
Plan B: 0.10x
Since the plans amounted to same for x texts. So, the suitable system of equation is,
5+0.03x = 0.10x
Solving the equation we get,
0.10x - 0.03x = 5
0.07x = 5
x = 5/0.07 = 71.42 (approximately)
