what is the soution to the equation 1/2 x + 3 = 2/3 x + 1
a.1/3
b.2/3
c.2
d.12
Answer:
d
Step-by-step explanation:
To eliminate the fractions in the equation multiply all term on both sides by the lowest common multiple of 2 and 3, that is 6
3x + 18 = 4x + 6 ← equation with no fractions
Subtract 4x from both sides
- x + 18 = 6 ( subtract 18 from both sides )
- x = - 12 ( multiply both sides by - 1 )
x = 12 → d

Is 0.67 a terminating or a repeating decimal
Answer:
Terminating decimal.
Step-by-step explanation:
A terminating decimal had an end.
0.67 ends after the 7; therefore it's terminating.
A recurring decimal does not end.
⅓ or 0.333333333... is a recurring decimal because it never ends. Similarly with ⅔ or 0.6666666666....
It is terminating good luck

Which segment is the image of AB reflected across the line y= -2
Answer:
GH
Step-by-step explanation:
If you look at y = -2, you can see that AB is one unit below it. Now if you flip this line segment across y = -2, all you have to do is count on unit up and find segment GH is in the correct position.
Answer:
The line segment GH is the answer.
Step-by-step explanation:
In the given figure we can see that point B of line AB lies one unit below the given y=-2. Now, when this line across y = -2, the point B will lie one unit above -2 that is H with the other end G.
So, GH is the correct answer.

Find the values of x and y. Write your answer in simplest form.
Answer:
y = 6√3 and x = 6
Step-by-step explanation:
this is a 30-60-90 triangle. The side opposite the 30° angle corresponds to the side of length 1 in the most basic 30-60-90 triangle; the side opp. 60° to the side of length √3; and the hyp. to the side of length 2.
To find y, write and solve an equation of ratios, as follows:
adj side adj side (adjacent to the 30° angle)
y √3
hypo hypo then (cross multiplying): 2y = 12√3, and
12 2 y = 6√3
If the hypo here is 12 and the adj side (y) is 6√3, then we can use the Pyth. Theorem to find the third side (x):
[12]² = [6√3]² - x² ↔ 144 = 36(3) - x² ↔ 36 = x². So x = 6 here.
Answer:
x = 6
y ≈ 10. 40
Step-by-step explanation:
Using the SOHCAHTOA principle we can solve for x and y since the angle is known and it is a right angle triangle.
hypotenuse = 12
adjacent = x
opposite = y
cos 60° = adjacent/hypotenus
cos 60° = x/12
cross multiply
x = 12 cos 60°
x = 12 × 0.5
x = 6
Finding y
sin 60° = opposite/hypotenuse
sin 60° = y/12
cross multiply
y = 12 sin 60°
y = 12 × 0.8660254038
y = 10.392304845
y ≈ 10. 40

Find the equation of the line below.
y=5x is your answer :)
The equation of the line passing through the points (1, 5) and (2, 10) is y = 5x.
Step 1: Calculate the slope (m) using the given points (1, 5) and (2, 10).
The slope (m) is given by the difference in y-coordinates divided by the difference in x-coordinates:
m = (10 - 5) / (2 - 1) = 5 / 1 = 5
Step 2: Select one of the points to use in the point-slope form. Let's choose (1, 5) as (x₁, y₁).
Step 3: Substitute the values into the point-slope form equation:
y - 5 = 5(x - 1)
Step 4: Distribute and simplify the equation:
y - 5 = 5x - 5
Step 5: Isolate 'y' on one side of the equation:
y = 5x - 5 + 5
y = 5x

The Logo For Super Snacks Company is Shown below. What is the area of the shaded region? Round to the nearest whole number. PLEASE HELP
Answer:
50.27 square inches
Step-by-step explanation:
If you look at the logo for the Super Snacks Company, you'll see it's basically a cylinder that has been cut and twisted, but if you just curve the top part the other way around, you'll have a perfect cylinder again.
We can then calculate the lateral surface area of the cylinder, to do so we use the following formula:
L = 2 * π * r * h
Which means we multiply by 2 by the constant π (3.1416) by the radius of the cylinder (in our case 2 inches, since the full diameter is 4 inches) and the height (in our case 4 inches). So, we enter the numbers in the formula and solve it:
L = 2 * 3.1416 * 2 * 4 = 50.2656 square inches.

Which value of y below is the solution to the system shown below. A) y=6 B) y=-1 C) y=-4 D) y=8
Equations: x+2y=27
2x+3y=46
first set the first equation equal to x
subtract 2y from both sides
x=27-2y now plug this in to the other equation
2(27-2y)+3y=46 distribute
54-4y+3y=46 --> 54-y=46 now subtract 54 from both sides -y=-8 --> D)y=8
If you weren't asked to show work you could just plug the choices given into the equation
Final answer:
By using the elimination method and subtracting the second given equation from the doubled first equation, we find that the solution for y in the system of equations is y=8.
Explanation:
We are tasked with finding the solution for y in the system of equations:
x + 2y = 27
2x + 3y = 46
To solve the system, we can use either the substitution method or the elimination method. Let's use the elimination method for this problem:
Multiply the first equation by 2:
(2)(x + 2y) = (2)(27)
2x + 4y = 54
Now we have:
2x + 4y = 54 (from step 1)
2x + 3y = 46 (original second equation)
Subtract the second equation from the first:
(2x + 4y) - (2x + 3y) = 54 - 46
y = 8Thus, y=8 is the solution to the system of equations, which corresponds to option D.

5x−2y=305, x, minus, 2, y, equals, 30
Complete the missing value in the solution to the equation.
(8,(8,left parenthesis, 8, comma
))right parenthesis
Answer:
The missing value is 5
The solution is (8,5)
Explanation:
The given equation is:
5x - 2y = 30
An order pair is written as (x , y). We are given (8 , ?)
This means that we want to find the y value that corresponds to x=8
To do this, we will substitute with x=8 in the given equation and solve for y
This is done as follows:
5x - 2y = 30
5(8) - 2y = 30
40 - 2y = 30
2y = 10
y = 5
This means that at x=8 and y=5, the equation is satisfied
(8,5) is a solution to the given equation
Hope this helps :)
Answer:
(8, 5)
Step-by-step explanation:
The given equation is:
5x - 2y = 30
We have to complete the given incomplete solution set (8, ?)
The first point in the ordered pair is always the x-value. So we are given an x-value and we have to find the corresponding y-value from the function.
Using x = 8 in the given function, we get:
5(8) - 2y = 30
40 - 2y = 30
- 2y = 30 - 40
- 2y = -10
y = 5
So, the value of y for x = 8 is 5. The complete ordered pair that satisfy the equation will be (8, 5)

Enter your answer in the box.
f(x)=
F(x)=(x+1)^2 that’s the answer
Answer:
[tex]f(x)=(x+1)^2[/tex]
Step-by-step explanation:
We have been given graph of a function. We are asked to find the equation of the graphed function.
Upon looking at our given graph, we can see that the graph represents a parabola.
We know that vertex form of a parabola is: [tex]y=a(x-h)^2+k[/tex], where, (h,k) represents the vertex of parabola.
We can see that vertex of our given parabola is at point [tex](-1,0)[/tex], so substituting the coordinates of vertex of parabola, we will get:
[tex]y=a(x--1)^2+0[/tex]
[tex]y=a(x+1)^2[/tex]
Now we will find the value of a using coordinates of point (0,1) in above equation.
[tex]1=a(0+1)^2[/tex]
[tex]1=a(1)^2[/tex]
[tex]1=a*1[/tex]
[tex]1=a[/tex]
Therefore, the equation of our graphed function would be [tex]f(x)=(x+1)^2[/tex]

What is the approximate area of a semicircle with diameter of 22 inches
Answer:
Aprox 190 inch2
Step-by-step explanation:
A = [Pi*r^2]/2
A = 60.5*Pi
A = 189.97 inc2
Best regards
Answer:
190 Square inches
Step-by-step explanation:
Formula for a semicircle is A=3.14*r^2/2
R=11 because its half the diameter
11^2=121
121 * 3.14 = 379.94
379.94 / 2 = 189.97
189.97 is approximately 190.
(7+u)^2−(5+u)^2=6v, (2−v)^2−(6−v)^2=4u.
Solve for u in (7 + u)^2 - (5 + u)^2 = 6v
u = 3(v - 4)/2
Substitute u = 3(v - 4)/2 into (2 - v)^2 - (6 - v)^2 = 4u
8v - 32 = 6(v - 4)
Solve for v in 8v - 32 = 6(v - 4)
v = 4
Substitute v = 4 into u = 3(v - 4)/2
u = 0
Therefore,
u = 0
v = 4
