Answer:
They have different slopes but the same y-intercept, so they have one solution.
Step-by-step explanation:
Both equations are organized in slope-intercept form, y=mx+b. m is the slope and b is the y-intercept.
In the first equation, the slope is 1/2 and the y-intercept is -3.
In the second equation, the slope is -1/2 and the y-intercept is -3.
These two equations have different slopes, in fact, the second equation has the same slope except negative. This means that they travel with the same steepness but one goes up and the other goes down.
However, they have the same y-intercepts. This means that they both intercept the same point on the y axis. Wherever two equations intercept is their solution.
Therefore, these two equations have one solution.

Option A is correct, the value of y is 57 degrees in the triangle.
We have to find the value of y in the given triangle.
Initially let us find the adjacent angle or interior angle which is adjacent to 114 degrees.
We know the straight line has an angle of 180 degrees
114+x=180
x=66 degrees.
By angle sum property the sum of three angles is 180 degrees.
66+y+y=180
66+2y=180
Subtract 66 from both sides:
2y=180-66
2y=114
Divide both sides by 2:
y=57 degrees
Hence, the value of y is 57 degrees in the triangle.

A student solved the equation below by graphing. log Subscript 6 Baseline (x minus 1) = log Subscript 2 Baseline (2 x + 2) Which statement about the graph is true? The curves do not intersect. The curves intersect at one point. The curves intersect at two points. The curves appear to coincide.
Answer:
A.) The curves do not intersect.
Step-by-step explanation:
By looking at the graph, we can see that the curves do not intercept, meaning that the equation has no solutions.
Graphs of logarithmic functions:First, here we have the graph of the lines:
y = log₆(x - 1)y = log₂(2x + 2)Which can be seen at the end of the answer.
In the graph, you can see that the lines never do intercept, this means that the equation:
log₆(x - 1) = log₂(2x + 2)
Has no solutions.

Janie ordered boxed lunches for a student advisory committee meeting. Each lunch costs $4. The total cost of the lunches is $47, including a $7 delivery fee. Write and solve an equation to find x, the number of boxed lunches Janie ordered.
Answer:
10 lunches
Step-by-step explanation:
$47-$7=$40
40/4=10
Hello, 928747!
So we are trying to find how many boxed lunches Janie ordered.
Each box is $4.00 and the total cost is $47.00 + delivery fee of $7.00
So to find this, we will first subtract the delivery fee because that does not count towards the lunches.
47 - 7 = 40
So the boxed lunches cost $40.00
To find how many Janie ordered, we will divide 4 by 40
40 ÷ 4 = 10
So Janie bought 10 boxed lunches.
The equation would be (47 - 7) ÷ 4

A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage. If they share one sausage, they can eat it in 6 seconds. How long does it take each animal to eat a sausage alone?
Answer:
Kitten is 15 seconds and dog is 10 seconds
In work and time the time taken is inversely proportional to the work done. Work and time is a concept to solve the problems of work related question in a given time.The kitten eats a sausage in 15 seconds and puppy eats a sausage in 10 seconds.
What is concept of Work and time?
In work and time the time taken is inversely proportional to the work done. Work and time is a concept to solve the problems of work related question in a given time
Given-Puppy and kitten eats one sausage combined in 6 sec.
A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage.
Let puppy eats a sausage in [tex]x[/tex] seconds and kitten eats a sausage in [tex]y[/tex] seconds.
As Puppy and kitten eats one sausage combined in 6 sec.Thus,
[tex]\dfrac{1}{x} +\dfrac{1}{y} =\dfrac{1}{6}[/tex]
Let above equation is equation one.
A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage. Thus
[tex]\dfrac{1}{x} -\dfrac{1}{y}=\dfrac{1}{5}[/tex]
Put this value of [tex]x[/tex] in the the equation one to get the value of y. Therefore,
[tex]\dfrac{1}{6} -\dfrac{1}{y}-\dfrac{1}{y}=\dfrac{1}{5}[/tex]
[tex]-\dfrac{1}{2y}=\dfrac{1}{5}-\dfrac{1}{6}[/tex]
[tex]-\dfrac{1}{2y}=-\dfrac{1}{30}[/tex]
[tex]y=15[/tex]
Thus the kitten eats a sausage in 15 seconds.
Put the value of y in equation one. thus,
[tex]\dfrac{1}{x} +\dfrac{1}{15} =\dfrac{1}{6}[/tex]
[tex]\dfrac{1}{x} =\dfrac{1}{6}-\dfrac{1}{15}[/tex]
[tex]\dfrac{1}{x} =\dfrac{9}{90}[/tex]
[tex]x=10[/tex]
Thus the puppy eats a sausage in 10 seconds.
Hence the kitten eats a sausage in 15 seconds and puppy eats a sausage in 10 seconds.

a cone has a height of 4 ft and a volume of 7.77 Ft cubed determine its radius to the nearest tenth of a foot
Answer:
The radius of the cone is approximately 1.4 feet
Step-by-step explanation:
The given parameters of the cone are;
The height of the cone, h = 4 ft.
The volume of the cone, V = 7.77 ft.³
The volume, 'V', of a cone is given by the following formula;
V = 1/3 × π·r²·h
Where;
V = The volume of the cone = 7.77 ft.³
r = The radius of the cone
h = The height of the cone = 4 ft.
By substituting the vales of 'h' and 'V' in the above equation, we have;
7.77 ft.³ = 1/3 × π × r² × 4 ft.
∴ r = √(3 × 7.77 ft.³/(π × 4 ft.)) = 1.36196580784 ft.
∴ The radius of the cone, r ≈ 1.4 ft. (rounding the answer to the nearest 10th)

Rewrite the equation by completing the square.
x^2 - 4x + 3 = 0
Answer:
the answer would be x=3,1
Answer:
After completing the square, we can say:
(x - 2)² = 1
If we solve for x, this tells us that x has a value of both 1 and 3.
Step-by-step explanation:
Given:
x² - 4x + 3 = 0
We can complete the square by adding 1 to both sides:
x² - 4x + 4 = 1
(x - 2)² = 1
We can then solve for x by saying:
(x - 2)² = 1
x - 2 = √1
x = 2 ± 1
x = 1, 3
if √2 = 1.414 then find the value of (√50+√72) please solve
Given:
[tex]\sqrt{2}=1.414[/tex]
To find:
The value of [tex]\sqrt{50}+\sqrt{72}[/tex].
Solution:
We have,
[tex]\sqrt{50}+\sqrt{72}[/tex]
It can be rewritten as
[tex]=\sqrt{2\times 25}+\sqrt{2\times 36}[/tex]
[tex]=\sqrt{2}\times \sqrt{25}+\sqrt{2}\times \sqrt{36}[/tex] [tex][\because \sqrt{ab}=\sqrt{a}\sqrt{b}][/tex]
[tex]=5\sqrt{2}+6\sqrt{2}[/tex]
[tex]=11\sqrt{2}[/tex]
Putting [tex]\sqrt{2}=1.414[/tex], we get
[tex]=11(1.414)[/tex]
[tex]=15.554[/tex]
Therefore, the value of given expression is 15.554.
