The solution of B(x) = 18 - 0.5x with x being -2, 0, 5 is 19, 18 and 15.5.
How to evaluate functions?Finding the value of f(x) =... or y =... that corresponds to a certain value of x is what it means to evaluate a function. Simply swap out all instances of x with the value of x to do this. For example, if we are requested to evaluate f(4), then the value 4 has been given to x.Given:
B(x) = 18-0.5x
x = -2, 0, 5
Putting the values of x to find the result of the function.
B(-2) = 18 - 0.5 × (-2) = 18 + 1 = 19
The required solution of the function at x = -2 is f(-2) = 19.
B(0) = 18 - 0.5 × (0) = 18
The required solution of the function at x = 0 is f(0) = 18.
B(5) = 18 - 0.5 × (5) = 18 - 2.5 = 15.5
Thus, the required solution of the function at x = 5 is f(5) = 15.5.

after school, a group of students decides to have a snowball fight. with 2 students on a team, they can make 6 snowballs per minute. with 10 students on a team, they can make 30 snowballs per minute. what is the slope in this situation?
Based on the calculations using the given points, the slope in this situation is equal to 5.
What is a slope?A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.
How to calculate the slope of a line?Mathematically, the slope of any straight line can be calculated by using this formula;
[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
Substituting the given points into the formula, we have;
Slope = (30 - 10)/6 - 2)
Slope = 20/4
Slope = 5.
In conclusion, the slope of the line that passes through the given points is equal to 5.

529 One digit is right, but in the wrong place
Answer:
987
Step-by-step explanation:
You want to determine a three-digit combination based on clues about which digits are right and/or correctly placed.
Clue 1This tells you one of digits 1, 2, or 7 is correct and correctly placed.
Clue 2 tells you that digit is not 1. Clue 4 tells you that digit is not 2.
7 is correctly placed as the 3rd digit
Clue 2We already know that 1 is not the correct digit. This means 3 must be the first digit, or 8 must be the first or second digit.
Clue 3We already know that 7 is a correct digit, properly placed as the 3rd digit. Since 1 is not a correct digit, 9 must be a correct digit, properly placed as the 1st digit.
9 is correctly placed as the 1st digit
Combining this fact with Clue 2 means ...
8 is correctly placed as the 2nd digit
The combination is 987.

Given m/8= 86° and m/4= (4x + 2)°, what is the value of x ?
X =
Bring the variable to the left and the remaining values to the right to define the value of x. If m/8 = 86° and m/4 = (4x + 2)° then value of x = 21.
How to find the value of x?Any of the algebraic expressions, including addition, subtraction, multiplication, and division, should be used. Bring the variable to the left and the remaining values to the right to determine the value of x. To determine the outcome, simplify the values.
Let the m/8 = 86° and m/4 = (4x + 2)°
m ∠4 = m ∠8 (Corresponding angles are equal)
To estimate the value of x
4x + 2 = 86
Substracting both sides of the equation by 2, we get
4x + 2 - 2 = 86 - 2
simplifying the above equation,
4x = 86 - 2
4x = 84
Dividing both sides of the equation by 4, we get
4x / 4 = 84 / 4
x = 21
Therefore, the value of x = 21.

A passbook savings account has a rate of 10% Find the effective annual yield if the interest is compounded daily.
The effective annual yield if the interest is compounded daily is 10.5155 %.
The annual interest rate or rate of return that an investor is entitled to over a particular time period is known as effective annual yield.
In the case of daily, there are 360 days in a year.
Therefore, making n = 360.
Therefore, the effective annual yield if the interest of 10% is compounded daily when r = 10 % and n = 360 will be:
Y = ( 1 + r/n )ⁿ - 1
Y = ( 1 + 0.1 / 360 )³⁶⁰ - 1
Y = ( 1 + 0.000277 )³⁶⁰ - 1
y = 1.105155 - 1
Y = 0.105155
However, since it is in decimal form, we must first multiply it by 100 before adding the symbol "%" after the last digit of the value.
Therefore,
Y = 0.105155 × 100%
Y = 10.5155 %

Standard form is used, for instance, in the linear equation 6x+5y=11. This method makes finding an equation's two intercepts very simple (x and y) .Y = mx + c is the cartesian equation for a straight line, where m denotes the gradient of the line and c denotes the location of its y-axis intersection.An infinitely long object without any width, depth, or curvature is a line. Since they can exist in two, three, or higher dimensions, lines are one-dimensional objects.We know that when a straight line passes through (a,b) with slope m then the equation of the line is given by:
y - b = m ( x - a )
