−36+x<8 whats is the x
Answer:
Therefore, the possible values of x are all numbers less than 8.
Step-by-step explanation:
To find the value of x, we need to isolate the variable on one side of the inequality.
To do this, we can subtract 36 from both sides of the inequality to get -36 + x < 8 - 36.
This simplifies to -36 + x < -28.
Next, we can add 36 to both sides to get x < -28 + 36, which simplifies to x < 8.
Therefore, the possible values of x are all numbers less than 8.

Step-by-step explanation:
A soccer training camp charges $9.50 per hour for training, plus a flat fee for equipment rental. The total fee for 12 hours of training was $128.
A) Write and solve a linear equation to find the equipment rental fee.
B) How much would it cost for 6 hours of training?
(High school)
a) The linear function used to find the equipment rental fee is of: y = 9x + 20.
b) The cost for 6 hours of training is of: $74.
How to define the linear function?The linear function is defined considering it's slope-intercept format, given as follows:
y = mx + b.
The coefficients of the function are given as follows:
m is the slope, representing the cost per hour.b is the intercept, representing the flat fee.A soccer training camp charges $9.50 per hour for training, hence the slope is of:
m = 9.
The total fee for 12 hours of training was $128, hence the intercept b is obtained as follows:
128 = 9(12) + b
b = 128 - 108
b = 20.
Hence the function is defined as follows:
y = 9x + 20.
The cost for six hours of training is obtained as follows:
y = 9(6) + 20 = $54.

Does the following system have a unique solution? Why?
Compare the investment below to an investment of the same principal at the same rate compounded annually.
principal: $6,000, annual interest: 6%, interest periods: 6, number of years: 18
The investment compounded annually has a higher final value than the investment you described because the annual compound interest rate is higher.
What is compound interest?
Compound interest is a type of interest that is calculated on the initial principal of an investment as well as any accumulated interest. In other words, compound interest is interest that is earned on both the original principal and on the accumulated interest from previous periods.
To compare the investment you described to an investment of the same principal at the same rate compounded annually, we need to calculate the final value of each investment after 18 years.
For the investment you described, the final value can be calculated using the formula:
FV = P(1 + r/n)^(nt)
Where FV is the final value, P is the principal, r is the annual interest rate, n is the number of interest periods per year, and t is the number of years.
Plugging in the values given in the problem, we get:
FV = $6,000(1 + 0.06/6)^(6*18) = $6,000(1.01)^108 = $12,688.80
For the investment compounded annually, the final value can be calculated using the same formula, but with n = 1:
FV = $6,000(1 + 0.06/1)^(1*18) = $6,000(1.06)^18 = $15,848.75
Hence, the investment compounded annually has a higher final value than the investment you described because the annual compound interest rate is higher. The difference in final value between the two investments is $15,848.75 - $12,688.80 = $3,159.95.

Find the coordinates of the circumcenter of the triangle with the given vertices.

find the circumvented
The coordinates of the circumcenter of the triangle with the vertices H(-10, 7), J(-6, 3) and K(-2, 3) is (-4, 9).
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the angles of a triangle is always 180°
The given points are H(-10, 7), J(-6, 3) and K(-2, 3)
Since, Circumcenter of triangle is equidistant from vertices,
Therefore, H(-10, 7), J(-6, 3) and K(-2, 3) are equidistant from circumcenter O,
Let the coordinate of O be (x,y).
OH = OJ
(x + 10)² + (y - 7)² = (x + 6)² + (y - 3)²
x² + 100 + 20x + y² + 49 - 14y = x² + 36 + 12x + y² + 9 -6y
8x - 8y + 104 = 0
x - y + 13 = 0 (1)
Also, OH = OK
(x + 10)² + (y - 7)² = (x + 2)² + (y - 3)²
x² + 100 + 20x + y² + 49 - 14y = x² + 4 + 4x + y² + 9 - 6y
16x - 8y + 136 = 0
2x - y + 17 = 0 (2)
By solving equation (1) and (2),
x = -4
y = 9
The coordinate of the circumcenter is (-4, 9).
Hence, this is the required answer.

The value of angle x is 161 degree. So the option B is correct.
In the given question, lines h and j are parallel and cut by transversal k.
We have to find the measure of angle x and choose the correct option.
The diagram of the given question is given below:
From the given diagram using the corresponding angle theorem
x = y
As we know that the angle of straight line is 180 degree.
So x+19 = 180
Subtract 19 on both side, we get;
x = 161 degree

The translated coordinates of B is B'(97,69).
What is translation?A translation is a geometric change in Euclidean geometry that involves moving each point in a figure, shape, or space by the same amount in one direction. A translation may alternatively be thought of as moving the origin of the coordinate system or as adding a constant vector to each point.
Given, point B with coordinates (95, 71) is mapped onto B' through a translation by vector (2,-4).
That means, the translation is 2 units right and 4 units down.
A positive number means moving to the right and a negative number means moving to the left.
The number at the second term represents up and down movement. A positive number means moving up, and a negative number means moving down.
So, B (95, 71) → B' (95 + 2, 73 -4)
B (95, 71) → B' (97, 69)
Therefore, the coordinates of B' is (97, 69).
