Solve the equation
3/4x+3-2x= -1/4+1/2x+5
Please help I have tried everything and I haven’t gotten the right answer and it won’t let me move on

Answers

3/4x + 3 - 2x = -1/4 + 1/2x + 5

Put in terms of 4 as denominator
3/4x + 12/4 - 8/4x = -1/4 + 2/4x + 20/4

Combine like terms
-5/4x + 12/4 = 2/4x + 19/4

Simplify
12/4 = 7/4x + 19/4
-7/4 = 7/4x
x = -1 :)

Check:
3/4(-1) + 3 - 2(-1) = -1/4 + 1/2(-1) + 5
-3/4 + 3 + 2 = -1/4 - 1/2 + 5
-3/4 + 5 = -3/4 + 5
-3/4 = -3/4 :)

If f(x) = 1 - 2x^3, find the inverse of f.

Answers

Swap x and y's positions

f(x) is another way of saying y, so basically tha initial function is y = 1-2x^3.

Change it up to x = 1-2y^3 and solve for y

X - 1 = - 2y^3

(X - 1)/-2 = y^3

So the cube root of ((x-1)/2) = y

Answer:

B, E, F

Step-by-step explanation:

Answer:

B, F

Step-by-step explanation:

A is false; the slope of function Z is 1/4 and the slope of function W is 1/2. 1/2 is greater than 1/4.

B is true. The slope of function Z is less then the slope of function W.

C is false, the y-intercept of function Z is -2 and the y-intercept of function W is -1. They are not the same number.

D is false, the y-intercept of function W is greater than Function Z.

E is false, -3 and -3 are equal

Function W:

y = 1/2x - 1

y = 1/2(-4) - 1

y = -4/2 = -2

y = -2 - 1

y = -3

Function Z:

y = 1/4x - 2

y = 1/4(-4) - 2

y = -1 - 2

y = -3

F is true, if y = -4 for functions W and, they would both be equal.

9-3 additional practice circles in the coordinate plane

Answers

Answer:

1. The center is (-5, 6)

The radius is 11

2. The center is (3, -9)

The radius is 6

3. The center of the circle is (-4, -2)

The radius is 3

4. The coordinate of the center of the circle is (2, 2)

The radius of the circle is 4

5. The equation of the circle is (x - 4)² + (y + 3)² = 2²

6. The equation of the circle is (x + 1)² + (x - 10)² = 7²

7. The given point (6, 8) does not lie on the circumference of the circle

8. Yes, the point (√17, 4) lies on the circumference of the circle

9. Please find the attached graph created with the aid of MS Excel

10 Please find the attached graph created with the aid of MS Excel

11. The equation of the circle is (x - a)² + (y - b)² = c²

12. The equation of the circle is x² + y² = 1

Step-by-step explanation:

1. The equation of the circle is (x + 5)² + (y - 6)² = 121

The standard form of the equation of a circle is (x - h)² + (y - k)² = r²

Where;

The center of the circle = (h, k)

The radius of the circle = r

By comparison we have;

h = -5, k = 6, and r = √121 = 11

The center of the circle, (h, k) = (-5, 6)

The radius of the circle, r = 11

2. (x - 3)² + (x + 9)² = 36

Similar to question 1, above, we have by comparison;

h = 3, k = -9, r = √36 = 6

The center of the circle, (h, k) = (3, -9)

The radius of the circle, r = 6

3. From the graph of the circle on the coordinate plane, we have;

The center of the circle = (-4, -2)

The radius of the circle =  -1 - (-4) = 3

4. From the graph of the locus of the circle, we have;

The coordinate of the center of the circle, r = (2, 2)

The length of the radius of the circle = The distance from the center  to the point (-2, 2)

Therefore, the radius of the circle, r = 2 - (-2) = 4

5. The given radius of the circle, r = 2

The center of the circle, (h, k) = (4, -3)

The equation of a circle in standard form is  (x - h)² + (y - k)² = r²

By comparison, we have the equation of the circle given as follows;

(x - 4)² + (y - (-3))² =  (x - 4)² + (y + 3)² = 2²

The equation of the circle is (x - 4)² + (y + 3)² = 2²

6. The given radius of the circle, r = 7

The center of the circle, (h, k) = (-1, 10)

The equation of a circle in standard form is  (x - h)² + (y - k)² = r²

By comparison, we have the equation of the circle given as follows;

(x - (-1))² + (y - 10)² = (x + 1)² + (y - 10)² = 7²

The equation of the circle is (x + 1)² + (x - 10)² = 7²

7. The given point = (6, 8)

The radius, r = 4

The center of the circle = (3, 5)

The point lies on the circle if the distance. 'd', from the point to the center of the circle = The radius of the circle

∴ d = √((6 - 3)² + (8 - 5)²) = √((3² + 3²) = √(18) = 3·√2

Given that the distance from the point to the center of the circle, d = 3·√2 ≠ 4 = r, the point (6, 8), does not lie on the circumference of the circle

8. The point = (√17, 4)

Radius, r: 9

The center: (0, -4)

The distance from the point to the center of the circle, d = √((√17 - 0)² + (4 - (-4))²) = 9 = r, the radius of the circle

Therefore, given that the distance of the point from the center of the circle = The radius of the circle, the point, (√17, 4), lies on the circumference of the circle

9. The given equation of the circle is (x - 5)² + (y - 1)² = 49

Comparing with the equation of a circle in standard form, we have;

The center of the circle, (h, k) = (5, 1)

The radius of the circle, r = √49 = 7

Please find the attached graph created with the aid of MS Excel

10. The given equation of the circle is x² + (y - 3)² = 25

The center of the circle, (h, k) = (0, 3)

The radius of the circle, r = √25 = 5

Please find the attached graph created with the aid of MS Excel

11. Given that the center of the circle is (a, b) and the radius of the circle is c, the equation of a circle in standard form, (x - h)² + (y - k)² = r², becomes;

(h, k) = (a, b)

r = c

∴ (x - a)² + (y - b)² = c²

12. The diameter of the circle, d = 2 in.

The center of the circle = The origin with coordinates, (0, 0)

Therefore;

The radius of the circle. r = d/2 = 2 in./2 = 1 in.

The center of the circle, (h, k) = (0, 0)

The equation of the circle is therefore;

(x - 0)² + (y - 0)² = 1²

Which gives the equation of the circle as x² + y² = 1.

Hudson wants to write a letter to his friend. He took out
square paper which covers the total area of 225 feet^2
.
What is the length of any side of the paper?

Answers

Answer:

length = 15 feet.

Step-by-step explanation:

This paper is 15 feet across on any side. Who will deliver this monster?

Area = s^2 where s is the length of 1 side.

Area = 225 feet^2  (You sure this isn't inches).

s^2 = area

s^2 = 225        Take the square root of both sides of the equation.

sqrt(s^2) = sqrt(225)

s = 15

There are between 24 and 40 students in a
class.
The ratio of boys to girls is 4:7
How many students are in the class?

Answers

Answer:

Step-by-step explanation:

The ratio of boys is 4/11

You need a number that is divisible by 11.

11 represents the number of students in the class. That was obtained by adding 4 and 7 together. So there are 4/11 boys and 7/11 girls.

You could try 33 which is between 24 and 40

4/11 * 33 = 12

There are twelve boys in the class.

7/11 * 33 = 21

There are 21 girls in the class.

21 + 12 = 33 which is exactly what you need.

John is 8 years younger than Ahmad. If the sum of their ages is 38, how old is John?

Answers

Let x equal Ahmad’s age.
Since John is 8 years younger than Ahmad, the equation would be as follows:

x+x-8=38

Solve for x:

2x-8=38
38+8=46
2x=46
x=23

23 is Ahmad’s age, subtract 8 from this and you’ll get 15 for John’s age.

Mr. Jones' other friend Ms. O'Neill has "x" meters of fencing, what is the maximum area in square meters she can have?

Answers

Answer:

[tex]Max\ Area = \frac{x^2}{16}[/tex]

Step-by-step explanation:

Given

[tex]P = x[/tex] ---- the perimeter of fencing

Required

The maximum area

Let

[tex]L \to Length[/tex]

[tex]W \to Width[/tex]

So, we have:

[tex]P = 2(L + W)[/tex]

This gives:

[tex]2(L + W) = x[/tex]

Divide by 2

[tex]L + W = \frac{x}{2}[/tex]

Make L the subject

[tex]L = \frac{x}{2} - W[/tex]

The area (A) of the fence is:

[tex]A = L * W[/tex]

Substitute [tex]L = \frac{x}{2} - W[/tex]

[tex]A = (\frac{x}{2} - W) * W[/tex]

Open bracket

[tex]A = \frac{x}{2}W - W^2[/tex]

Differentiate with respect to W

[tex]A' = \frac{x}{2} - 2W[/tex]

Set to 0

[tex]\frac{x}{2} - 2W = 0[/tex]

Solve for 2W

[tex]2W = \frac{x}{2}[/tex]

Solve for W

[tex]W = \frac{x}{4}[/tex]

Recall that:

[tex]L = \frac{x}{2} - W[/tex]

[tex]L = \frac{x}{2} - \frac{x}{4}[/tex]

[tex]L = \frac{2x- x}{4}[/tex]

[tex]L = \frac{x}{4}[/tex]

So, the maximum area is:

[tex]A = L * W[/tex]

[tex]A = \frac{x}{4}*\frac{x}{4}[/tex]

[tex]Max\ Area = \frac{x^2}{16}[/tex]
