When given a system of equations in slope-intercept form, is graphing or substitution the most efficient method to solve? Explain.
Choose the best answer below.
A.
Substitution is the only method that should be used if the answer involves integer values. If the answer involves values that are not integers, graphing would be more efficient because an exact answer can be obtained. It is easier to read graphs when the point of intersection does not occur at integer values.
B.
Graphing is the only method that would be appropriate to use here because it is not possible to use the substitution method if both equations are in slope-intercept form.
C.

What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, a system of equations in slope-intercept form y₁ = m₁x₁ + b₁ and
y₂ = m₂x₂ + b₂.
We can use both substitution and graphing depending on the numerical values of the variables.
If the solution involves integer numbers, graphing and substitution are the proper methods to utilize. Substitution would be more effective since an accurate solution may be reached if the solution involves values that are not integers. If the intersection point doesn't have integer values, it can be challenging to understand graphs, so using this approach to solve would be ineffective.

Edelia is planning a crawfish broil party. Each case of crawfish weighs 20 pounds of crawfish. If each pound of crawfish contains 15-25 individual crawfish, approximately how many crawfish can she serve if she buys 5 cases?
Answers
Edelia can serve approximately 1,500 to 2,500 crawfish if she buys 5 cases.
Given:
Each case of crawfish weighs 20 pounds.Each pound of crawfish contains 15-25 individual crawfish.Edelia buys 5 cases.The theory of unit conversion and basic arithmetic is used to solve this question.
1. Finding the total weight of crawfish.
Total weight of crawfish = Weight per case × Number of cases
Total weight of crawfish = 20 pounds × 5 cases
Total weight of crawfish = 100 pounds.
2. Determining the range of crawfish count.
Since each pound of crawfish contains 15-25 crawfish, we can calculate the minimum and maximum number of crawfish as follows:
Minimum crawfish count = Minimum crawfish per pound × Total weight of crawfish
Minimum crawfish count = 15 crawfish/pound × 100 pounds
Minimum crawfish count = 1500 crawfish.
Maximum crawfish count = Maximum crawfish per pound × Total weight of crawfish
Maximum crawfish count = 25 crawfish/pound × 100 pounds
Maximum crawfish count = 2500 crawfish.
Therefore, Edelia can serve approximately 1,500 to 2,500 crawfish if she buys 5 cases of crawfish.

Drug Name Half-life
-----------------------------------
Acetaminophen 1-4 hours
Ibuprofen 1.8-2 hours
Loratadine 8.4 hours
Lithium 8 hours
Diphenhydramine 5.3-11.7 hours
The table above displays the half-lives of 5 common house hold drugs. The half-life (h) is the time is takes for a substance to reduce to half its initial value (A0). Half life can be used to solve for the amount (A) of a substance left after t time by using the following equation:
A=A^0⋅(12)^t/h

C. 212.17

Answers
Answer:
B. 106.07
Step-by-step explanation:
To make use of the given formula for amount remaining, we need to know the original amount (300 mg), the elapsed time (12 h), and the half-life of the substance of interest (8 h).
SetupUsing the given formula with the relevant values, we have ...
A = (300 mg)·(1/2)^(12/8)
