Solve for x and y
NEED FOR TEST
Answer:
x = 4 and y = 6
Step-by-step explanation:
With the way the equations are set up, substation is faster.
Just substitute -1/2x + 8 for the y in the first equation.
3x + 4(-1/2x + 8) = 36
And then you can just solve the equation. You would get x = 4.
Substitute 4 for x.
y = -1/2(4) + 8
y = 6

3) the Angles are: ∠VIO, ∠IOL, ∠OLE, ∠LEN, ∠ENT, ∠NTV, and ∠TVI.
4) the sides are: VI, IO, OL, LE, EN, NT, NV
5) It has seven sides.
6) TV and VI are called adjacent sides or adjacent edges because they are two sides that meet at the same vertex.
7) ∠E and ∠N are called adjacent angles.
8) ∠O and ∠L would also be adjacent angles. This is because, they share the same side.
9) the angles adjacent to ∠I are: ∠O and ∠V.
10) the line that goes from vertex V to vertex L (VL) can be called a diagonal.
A heptagon is a polygon with seven sides and seven angles.
It is a two-dimensional geometric shape with seven vertices and seven interior angles, each of which measures 128.57 degrees. The sum of the interior angles of a heptagon is 900 degrees.

Which two points would a line of fit go through to best fit the data?
(3, 6) and (7, 3)
(3, 7) and (9, 1)
(1, 9) and (5, 7)
(1, 7) and (2, 5)
Answer:
(a) (3, 6) and (7, 3)
Step-by-step explanation:
You want the two points that best describe a line of best fit through the data shown on the given graph.
Line of best fitA calculator finds the slope of the line of best fit to be about -0.74. The pair of points that best matches that is ...
(3, 6) and (7, 3) . . . . choice A
The line through these points has a slope of -0.75 and is very close to the best-fit line. The attachment shows how the various point pairs relate to the computed line. The answer choice points are the larger red dots.
__
Additional comment
The slope of the line of best fit is the ratio of the covariance of x and y to the variance of x:
m = cov(x, y)/var(x) = -7.744/10.455 ≈ -0.741

A 154-lb person burns 420 calories per hour riding an exercise bicycle at a rate of 15 mi/hr. Write a function rule to represent the total calories burned over time by that person. Explain how the information in the problem relates to the function.
Describe a rule for determining how much the store charges based on the number of turkey subs delivered.
The rule for determining how much the store charges based on the number of turkey subs delivered will depend on the pricing structure that the store uses. One possible rule is a linear function, where the cost of each turkey sub is a fixed amount and the total cost is proportional to the number of subs delivered.
For example, if the store charges $5 for each turkey sub, the rule could be:
Total cost = $5 per sub * Number of subs delivered
So if the store delivers 10 turkey subs, the total cost would be:
Total cost = $5 per sub * 10 subs = $50
If the store delivers 20 turkey subs, the total cost would be:
Total cost = $5 per sub * 20 subs = $100
This rule assumes that the cost per sub remains constant regardless of the number of subs delivered. However, in reality, the cost per sub may vary depending on factors such as the cost of ingredients and labor, and the store's desired profit margin.

theta is a right angled triangle tan theta=24/43) work out the value of theta give your answer to 1 decimal place
Answer:
We know that tan(theta) = opposite/hypotenuse = 24/43.Using inverse tangent, we can find the angle theta:theta = tan^(-1)(24/43)Using a calculator, we can find:theta ≈ 29.6 degrees (rounded to 1 decimal place)Therefore, the value of theta to 1 decimal place is approximately 29.6 degrees.
Step-by-step explanation:
The value of theta in a right angle triangle for which tan(theta) = 24/43 can be found using the inverse tangent function, also known as arctan. When evaluated, theta equals approximately 29.4 degrees.
Explanation:In trigonometry, the tangent of an angle in a right angle triangle is the ratio of the side opposite to the angle to the side adjacent to the angle. Here, tan(theta) = 24/43, which means the ratio of the opposite side to the adjacent side is 24/43. To find the angle 'theta', you will need to use the inverse tangent function, commonly known as arctan or tan^-1.
In this case, theta = arctan(24/43). Use a calculator and ensure it's set to give the answer in degrees, not radians. The answer would be approximately 29.4 degrees to 1 decimal place.

A circular pool has a radius of 6 ft. What is the approximate circumference of the pool?
A. 19 ft
B. 38 ft
C. 113 ft
D. 452 ft
Answer: Option B. 38 ft
Step-by-step explanation:
To find the circumference of a circle, we use the formula C = 2πr, where C represents the circumference, r represents the radius of the circle, and π (pi) is a mathematical constant that is approximately equal to 3.14.
In this problem, we are given that the radius of the circular pool is 6 ft. We can substitute this value into the formula to find the circumference:
C = 2πr
C = 2π(6)
C ≈ 37.7 ft
Therefore, the approximate circumference of the pool is 37.7 feet. This is closest to answer choice B, which is 38 ft.

Answer:
4 1/5 or 21/5 (improper fraction)
Step-by-step explanation:
To find the area of a rectangle, there is a formula:
[tex]A=lw[/tex]
So, we know the length is 7ft, and the width is 6/10.
Substitute in the 2 values:
[tex]A=7(6/10)[/tex]
From here, you can go 2 ways:
1) Change 6/10 to a decimal, 0.6
-Then, multiply 7 x 0.6
- This equals 4.2, which as a fraction is 4 1/5 or 21/5
2) Turn 7 into a fraction, 7/1 and multiply the numerators and denominators:
- 7/1 x 6/10 = 42/10 = 21/5
Hope this helps! :)
12(6) + 14 ⋅ 2 ⋅ 2 =
Answer: 128
Step-by-step explanation:
12(6)+ 14x2x2
Use PEMDAS1.Do the parentheses-(These are parentheses) first
When the number it touching another number like this, you need to multiply them together
12x6=72
72+14x2x2
2. Then do exponents, but we don't have any so next to multiplying
2x2=4
72+14x4
14x4=56
3. Now we divide, but we don't have to divide anything so now we add
72+56=128
4. There is no subtraction in the problem, so now we are done and the total is 128
