Answer:
2.) Infinitely many solutions
3.) No solutions
Step-by-step explanation:
To solve systems of equations graphically, you need to find where they intersect
2.) First put each equation in the form y=mx+b
x-y=6 -> y= x-6
2x=12+2y -> y= x-6
Then, graph each line
Since we have the same equation, the lines are on top of each other so there are infinitely many solutions as they intersect everywhere.
To check, plug a point in from the graph into both equations and you should get 0=0
3.) First put each equation in the form y=mx+b
1/2x-y=4 -> y=1/2x-4
2y=x+6 -> y=1/2x+3
Then, graph each line
Since the lines have the same slope but a different y intercept, the lines are parallel. Therefore, there are no solutions as they do not intersect.
To check your answer, you would one equation as the y in the other equation.
2(1/2x-4)=x+6, then solve for x
Then plug that x into the original equations, and you'll see they are not equal. Hope that helps!

Solve 2x=54xˆ(2/3)
Please, I need the step by step working to find the value of x
Answer:
x = 19683 or x = 0
Step-by-step explanation:
Solve for x:
2 x = 54 x^(2/3)
Hint: | Isolate the radical to the left hand side by reversing the equality.
2 x = 54 x^(2/3) is equivalent to 54 x^(2/3) = 2 x:
54 x^(2/3) = 2 x
Hint: | Eliminate the power on the left hand side.
Raise both sides to the power of three:
157464 x^2 = 8 x^3
Hint: | Move everything to the left hand side.
Subtract 8 x^3 from both sides:
157464 x^2 - 8 x^3 = 0
Hint: | Factor the left hand side.
Factor x^2 and constant terms from the left hand side:
-8 x^2 (x - 19683) = 0
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by -8:
x^2 (x - 19683) = 0
Hint: | Find the roots of each term in the product separately.
Split into two equations:
x - 19683 = 0 or x^2 = 0
Hint: | Look at the first equation: Solve for x.
Add 19683 to both sides:
x = 19683 or x^2 = 0
Hint: | Look at the second equation: Eliminate the exponent.
Take the square root of both sides:
Answer: x = 19683 or x = 0

Answer:A. Yes, they are inverse of each other.
B. Domain and range of the compositions is .
Step-by-step explanation:
A. We have, and .
Now, 'when two functions f and g are inverses of each other, they satisfy the property '.
So, we have,
Thus, we get for the given function f and g, .
Hence, they are inverse of each other.
B. Now, as we have,
That is, the composition of the functions is equal to the identity function.
Thus, the domain and range are the set of all real numbers respectively.

Carter has a fruit stand. In the morning, he has 25 1/2 pounds of peaches. He sells bags of peaches that each weigh 1 1/2 pounds. He will restock when he has less than 3 pounds of peaches left. Which solution represents how many bas of peaches, b, Carter will sell before he restocks?
Answer:
Carter will sell 17 bags of peaches before he restocks.
Step-by-step explanation:
Total pounds of peaches Carter have = [tex]25\frac{1}{2} = \frac{51}{2} = 25.5[/tex]
Weight of each bag = [tex]1\frac{1}{2} = \frac{3}{2} = 1.5[/tex] pound
Number of bag made = [tex]\frac{25.5}{1.5}[/tex] = 17
The number is fully divided , it means no of peaches left = 0 < 3
So,
Carter will sell 17 bags of peaches before he restocks.
The number of bas of peaches, b, Carter will sell before he restocks is 17.
Calculation of the number of peaches:Since he has 25 1/2 pounds of peaches. He sells bags of peaches that each weigh 1 1/2 pounds. He will restock when he has less than 3 pounds of peaches left.
So here
[tex]= 25.5 \div 1.5[/tex]
= 17

B: 112[tex]\pi[/tex][tex]cm^{3}[/tex]
C: 351.68[tex]cm^{2}[/tex]
Step-by-step explanation:
The cubic inches that can fill the cylinder is [tex]112\pi[/tex] and the decimal approximation 351.68 cm^3
The given parameters are:
Radius (r) = 4 cm
Height (h) = 7 cm
The area of the baseThe area of the base is:
[tex]A = \pi r^2[/tex]
So, we have:
[tex]A = \pi *4^2[/tex]
[tex]A = 16\pi[/tex]
Hence, the area of the base is [tex]16\pi[/tex]
The cubic inches that can fill the cylinderThis is the volume of the cylinder.
So, we have:
[tex]V = \pi r^2h[/tex]
Substitute known values
[tex]V = \pi * 4^2 * 7[/tex]
[tex]V = 112\pi[/tex]
Hence, the cubic inches that can fill the cylinder is [tex]112\pi[/tex]
The decimal approximationWe have:
[tex]V = 112\pi[/tex]
Expand
[tex]V = 112 * 3.14[/tex]
Evaluate the product
[tex]V = 351.68[/tex]
Hence, the cubic inches that can fill the cylinder is 351.68 cm^3
