Answer:
B
Step-by-step explanation:
1. Before anything, figure out the inequality symbol. Why? In the solutions, all of the inequalities are different so you narrow it down by figuring out the inequality sign.
2. "At most 50 pounds" means we can't go over 50 pounds, but the package can still equal 50, that's just the most it can be. This means we will have a line underneath because it includes the maximum number, 50, in the solution.
3. "At most" also means the package (x) cannot be over 50. The sign opening must face 50 because that shows x has to be less than. But it can equal 50, so the sign is [tex]x\leq 50[/tex]. That would be B.
4. About the numbers, the box weighs 2 pounds. This means it is x+2 because weight is not negative and it is ADDING weight to what we don't know. To isolate x, just do 50-2, and you get 48. That again proves b is the answer.

Given f(x)=4(2)^x
a. find f(4)
b. write your answer as a logarithmic expression
a) The numeric value at x = 4 is given as follows: f(4) = 64.
b) The logarithmic expression is given as follows: x = log2(16).
How to find the numeric value of a function or of an expression?To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.
The function for this problem is defined as follows:
f(x) = 4(2)^x.
At x = 4, the numeric value is found replacing the lone instance of x by 4, hence:
f(4) = 4(2)^4 = 64.
For the logarithmic expression, we obtain the inverse function, hence:
64 = 4(2)^x.
2^x = 16
x = log2(16).

Temasa has a 1:10 scale drawing of her doll house in the drawing the dimensions of the rectangular house are 7 1/5 inches by 4 4/5 inches.The actual length is 72
inches
12 inches equals 1 feet, what is the area of Temasa's doll house
to the nearest SQUARE FOOT?
The area of the Temasa's doll house is 31.5 square feet.
What is the scale factor?
The scale factor is a ratio that compares the measurements of an object on a drawing or map to the actual measurements of that same object in real life. It is usually expressed as a ratio in the format 1:n (or 1/n) where n is the scale factor.
We can start by using the scale factor of 1:10 to find the actual dimensions of the doll house.
Since the scale factor is 1:10, this means that for every 1 inch on the drawing, the actual measurement is 10 inches. So, to find the actual length and width of the doll house, we can multiply the measurements on the drawing by 10.
7 1/5 inches * 10 = 71 inches + 2 inches
4 4/5 inches * 10 = 44 inches + 8 inches
So, the actual length of the doll house is 71 inches + 2 inches = 73 inches, and the actual width is 44 inches + 8 inches = 52 inches.
To find the area of the doll house, we can multiply the length and width:
73 inches * 52 inches = 3788 square inches
To convert this to square feet, we can divide by 12^2, since 1 foot = 12 inches:
3788 square inches / (12 inches)^2 = 31.5 square feet (rounded to the nearest square foot)
Hence, the area of the Temasa's doll house is 31.5 square feet.

There are three angles in a triangle ABC. A triangle is a three-sided polygon and it has three angles. Each angle is formed by the intersection of two sides of the triangle.
In a triangle, the angle between two sides is measured in degrees and these angles are formed by the intersection of the two lines that represent the sides of the triangle. The three angles in a triangle are labeled with the corresponding vertex, for example, angle A, angle B, and angle C.
In a triangle, the sum of the three angles is always 180 degrees. This can be proved using the fact that a straight line is 180 degrees. If we draw a straight line, and divide it into two angles, which are supplementary angles. Therefore, these angles add up to 180 degrees. In a triangle, we can draw one straight line and divide it into three angles, which are supplementary angles, therefore the sum of the angles in a triangle is always 180 degrees.

How to solve systems of linear equation in two variables by substitution?.
Solving systems of linear equations in two variables by substitution involves isolating one of the variables and substituting its value into the other equation.
This can be done by adding or subtracting the same term from both sides of one equation and then using that result to substitute into the other equation.
For example, consider the system of equations below:
2x + 3y = 8
3x + 2y = 7
Start by solving for x in the first equation by subtracting 3y from both sides:
2x + 3y = 8
2x = 8 - 3y
x = (8 - 3y)/2
Now substitute this expression for x in the second equation:
3(8 - 3y)/2 + 2y = 7
24 - 9y + 2y = 7
11y = 17
y = 17/11
Finally, solve for x, add y = 17/11 to the first equation as follows:
2x + 3(17/11) = 8
2x + 51/11 = 8
2x = 8 - 51/11
x = (8 - 51/11)/2
x = 21/22
The solution is x=21/22 and y=17/11.

Using Composition of functions, the value of g(h(24)) = 1158.
What is meant by Composition of functions?A function is composed in mathematics when two functions, f and g, are used to create a new function, h, such that h(x) = g(f(x)). The function of g is being applied to the function of x, in this case. Therefore, a function is essentially applied to the output of another function.
The new function h is created by combining the two functions f and g, where h(x) = f(g(x)) for all x in g's domain where g(x) is in f's domain. Function composition is denoted by the notation h = f • g, also written as h(x) = (f • g)(x), which can be interpreted as "f of g of x."
Given,
g(x) = 2x + 4, h(x) = x² +1

How do you solve complex fractions with rational expressions?.
To solve a complex fraction, which is a fraction that contains one or more fractions in its numerator and/or denominator, you can follow these steps:
Factor the numerator and denominator of the complex fraction if possible. This will make it easier to cancel common factors.
Multiply both the numerator and denominator by the reciprocal of the fraction(s) in the denominator. This will eliminate the fraction(s) in the denominator, leaving a simplified expression.
Simplify the resulting expression by combining like terms, if possible.
Check your work by multiplying the numerator and denominator of the original complex fraction by the reciprocal of the fraction(s) in the denominator, and verifying that the simplified expression you obtained is equivalent.

Triangle ABC is a right triangle with the right angle at angle B. If the sine of angle A is ? and the longer leg is 52 inches, what is the length of the shorter leg of the triangle?
Answer:
The length of the shorter leg of the triangle can be calculated using the Pythagorean Theorem. The formula is a^2 + b^2 = c^2, where a is the length of the shorter leg, b is the length of the longer leg and c is the length of the hypotenuse. In this case, a^2 + 52^2 = c^2. The hypotenuse can be calculated by using the sine formula. c = (52/sinA). Substituting this value into the Pythagorean Theorem equation, a^2 + 52^2 = (52/sinA)^2. Solving for a, a = sqrt(52^2 - (52/sinA)^2).
