A set of equations is given below:
Equation A: y = x + 1
Equation B: y = 4x + 5
Which of the following steps can be used to find the solution to the set of equations?
x + 1 = 4x + 5
x = 4x + 5
x + 1 = 4x
x + 5 = 4x + 1
Answer:
x + 1 = 4x + 5
Step-by-step explanation:
To solve this set of equation you can just equalize them ot one another, as you can see they are already in Y form, which means that they have already been solved for Y, so that makes things easier for us, we just insert the second equation in the place of Y in the first one, and we can solve for "x".

There are two aircraft carriers, A and B, and the carrier A is longer in length the carrier B. The total length of these two carriers is 4178 feet, while the difference of their lengths is only 14 feet.
Answer:
Length of carrier A = 2096 feet Length of carrier B=2082 feet.Step-by-step explanation:
Given , two air craft carriers are A and B . The carrier A is longer than the carrier B in length.
Total length of two carriers =4178 feet
Difference of two carriers = 14 feet
Let
Length of carrier A =x feet
And
Legth of carrier B =y feet
According to question
The I equation is
x+y=4178
The II equation is
x-y= 14
Substitution method: In this method step I : we find value of x or y from the equation I
Step II: put the value of x or y in II equation then we get the value of another varaiable x or y
Step : Again put the obatined value of variable x or y from step II in equation I then we get value of other variable x or y .
By using substitution method ,
we find value of x from equation I
x= 4178-y
Now, put the value of x in equation II then we get
4178-y-y=14
4178-2y=14
4178-14=2y
4164=2y
[tex]y=\frac{4164}{2}[/tex]
y= 2082
Again , put the value of y in equation I
2082 +x=4178
x= 4178-2082
x=2096
Hence, the length of carrier A = 2096 feet
The length of carrier B= 2082 feet
Final answer:
To solve the problem, we set up two equations based on the given total length and the length difference of the two aircraft carriers. By solving these equations, we find that carrier A is 2096 feet long and carrier B is 2082 feet long.
Explanation:
The student's question involves solving a system of linear equations to find the lengths of two aircraft carriers, A and B. Given that the total length is 4178 feet and the length difference is 14 feet, we can set up the following equations:
Equation 1: A + B = 4178
Equation 2: A - B = 14
To solve for A and B, we can add the two equations together to eliminate B.
This gives us 2A = 4192, hence A = 2096 feet.
Substituting A back into one of the equations, we find B = 2082 feet.
Therefore, carrier A is 2096 feet long and carrier B is 2082 feet long.

Determine whether each of the functions log(n + 1) and log(n2 + 1) is o(log n)
Both functions log(n + 1) and log(n^2 + 1) are not o(log n). For large values of n, log(n + 1) is approximately equal to log n, and log(n^2 + 1) behaves like 2*log n, none of which grows strictly slower than log n.
To determine whether the functions log(n + 1) and log(n2 + 1) are o(log n), we'll use the definition of little-o notation. A function f(n) is said to be o(g(n)) if for any positive constant c > 0, there exists a threshold n0 such that for all n > n0, f(n) < c * g(n). In other words, f(n) grows slower than any constant multiple of g(n) as n approaches infinity.
Analysis for log(n + 1)
When n is very large, the +1 becomes negligible, and log(n + 1) behaves similarly to log n. Therefore,
log(n + 1) ≈ log n when n is large.
This implies that log(n + 1) is not o(log n) because it does not grow strictly slower than any multiple of log n.
Analysis for log(n2 + 1)
Using logarithm properties:
log(n2 + 1) < log(n2 + n2) = log(2n2) = log 2 + 2*log n.
As n grows, the constant term (log 2) becomes insignificant, and the function approaches the behavior of 2*log n. However, since there is a multiple of log n (which is 2*log n), this still means that log(n2 + 1) is not o(log n) because it grows faster, not slower, than log n.

A class tossed coins and recorded 165 heads and 172 tails. What is the experimental probability of tails?
Answer:
Probability of tails = 0.51
Step-by-step explanation:
Probability is the ratio of number of favorable outcome to the total number of outcomes.
Total number of outcomes = Total number of heads + Total number of tails
= 165 + 172 = 337
Number of favorable outcome = Total number of tails = 172
[tex]\texttt{Probability}=\frac{172}{337}=0.51[/tex]

What is the equation of the line that passes through (4,3) and (2,2)
Answer:
The equation of line is [tex]y=\frac{1}{2}(x)+1[/tex].
Step-by-step explanation:
Given information: The line passes through the point (4,3) and (2,2).
If a line passes through the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the equation of line is
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The line passes through the point (4,3) and (2,2), so the equation of line is
[tex]y-3=\frac{2-3}{2-4}(x-4)[/tex]
[tex]y-3=\frac{-1}{-2}(x-4)[/tex]
[tex]y-3=\frac{1}{2}(x-4)[/tex]
Using distributive property, we get
[tex]y-3=\frac{1}{2}(x)+\frac{1}{2}(-4)[/tex]
[tex]y-3=\frac{1}{2}(x)-2[/tex]
Add 3 on both sides.
[tex]y=\frac{1}{2}(x)-2+3[/tex]
[tex]y=\frac{1}{2}(x)+1[/tex]
Therefore the equation of line is [tex]y=\frac{1}{2}(x)+1[/tex].

From 1980 to 1990, the consumer price index (CPI) increased from 82.4 to 130.7. If a bottle of dish soap cost $0.74 in 1980 and the price of dish soap increased at the same rate as the CPI from 1980 to 1990, by approximately how much did the price of a bottle of dish soap increase from 1980 to 1990?
Using proportions, it is found that the price of a bottle of dish soap increased $0.43 from 1980 to 1990.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The percent increase, as a proportion, of the CPI is given by:
P = 130.7/82.4 = 1.5862.
Hence, for the price of the bottle:
Pb = $0.74 x 1.5862 = $1.17.
The difference is:
1.17 - 0.74 = $0.43.

a class voted for either kayaking, fishing, or hiking as their favorite summer activity. if hiking got 17% percent of the vote and fishing got 33%, what percentage of the class voted kayaking?
The percentage of the class that voted for kayaking is 50%.
Given data:
To find the percentage of the class that voted for kayaking, use the fact that the total percentage of votes adds up to 100%.
Hiking got 17% of the vote.
Fishing got 33% of the vote.
Let x be the percentage of the class that voted for kayaking.
Since the total percentage of votes is 100%:
17% + 33% + x = 100%
On solving for x:
x = 100% - (17% + 33%)
x = 100% - 50%
x = 50%
Hence, 50% of the class voted for kayaking.

What is the value of b2 - 4ac for the following equation? x(x + 8) = 9 28 64 100
Answer:
C) 100
Step-by-step explanation:
The given equation is x(x + 8) = 9
Distributing x insides, we get
x^2 + 8x = 9
Now set the equation equal to zero.
x^2 + 8x - 9 =0
Here a = 1, b = 8, and c = -9
b^2 - 4ac = (8)^2 - 4*1*-9
= 64 + 36
= 100
Therefore, b^2 - 4ac = 100.
Answer: C) 100

In the rhombus, m<1=8y-6. Find the value of y. Please help!!
Answer: 12
The value of y= 12.
Step-by-step explanation:
We know that the diagonal of rhombus are perpendicular bisector of each other.
i.e. the angle made at the intersection of diagonal is 90 degrees.
Thus , for the given figure m∠1 = 90°
Since it is given that m∠1 = 8y-6
Thus , 8y-6= 90
⇒8y=96 [Adding 6 both sides]
⇒ y = 12 [Dividing both sides by 8]
Hence, the value of y= 12.
