Answer 1

Answer:

The answer is x = 3

Step-by-step explanation:

5x + 9 = 24

5x +9 -9 = 24 - 9

5x = 15

x = 15/5 = 3

Therefore, x = 3

Kelly multiplied 5 to each side when she solved for x, which is incorrect.

Answer 2

Answer:

Kelly had incorrectly solved for [tex]x[/tex] where she had multiplied by [tex]5[/tex] instead of dividing by [tex]5[/tex] to find for [tex]x[/tex].

Step-by-step explanation:

How Kelly should have solved it:

[tex]5x+9 = 24[/tex]

[tex]5x + 9-9= 24-9[/tex]

[tex]5x=15[/tex]

[tex]5x\div 5=15\div 5[/tex] (mistake occurred during this step in Kelly's work where she had multiplied by [tex]5[/tex])

[tex]x=3[/tex]

Checking:

To check if [tex]x=3[/tex], we can use substitution:

[tex]5x+9 = 5(3)+9[/tex]

[tex]=15+9[/tex]

[tex]=24[/tex]

∴ The solution for [tex]x[/tex] is correct.

Hope this helps :)

Answer:

d=25 or d=2

Step-by-step explanation:

hope that helps!

Answer:

d=2/5 or d=2

Step-by-step explanation:

Step 1: Subtract -6d^2 from both sides.

−d2−12d+4−−6d2=−6d2−−6d2

5d2−12d+4=0

Step 2: Factor left side of equation.

(5d−2)(d−2)=0

Step 3: Set factors equal to 0.

5d−2=0 or d−2=0

d= 2/5 or d=2

Which is the graph of f(x) = x2 – 2x + 3?

Answers

Answer:

The correct answer is:

The graph will be the same width as the parent graph f(x) = x², but the vertex has been shifted to (1, 2).

Step-by-step explanation:

Since the value of a, the coefficient of x², is 1, this means the graph has not been stretched or shrunk. However, since the function is different than f(x)=x², we know that the vertex is not at (0, 0). We can write the function in vertex form to find the new vertex.

To write the function in vertex form, we find the value of b/2. The value of b in this function is -2; -2/2 = -1. We then square this: (-1)² = 1. This is what we add and subtract to the function (we must do both to preserve equality), giving us:

f(x) = x²-2x+1+3-1

The first three terms of this function can be written as the square (x+(b/2))²; this is (x-1)², and gives us f(x) = (x-1)²+3-1. Combining like terms, we have:

f(x) = (x-1)²+2

This is vertex form, f(x) = a(x-h)²+k, where (h, k) is the vertex. This means the vertex is at (1, 2) instead of (0, 0).

25 points if you answer. Martin Rode his bike 3 2/3 miles in 16 1/2 minutes. Assume he wrote the same speed the entire time. How fast did he ride in miles per minute?

Answers

Answer:

The speed is 2/9 miles per minute

Step-by-step explanation:

Speed is defined as the distance covered per unit time.

The formula for speed is given by:

[tex]Speed = \frac{distance}{time}[/tex]

Let s be the speed, d be the distance and t be the time then

[tex]s = \frac{d}{t}[/tex]

Given

[tex]d = 3\frac{2}{3} = \frac{11}{3}\ miles\\t = 16\frac{1}{2} = \frac{33}{2}\ minutes[/tex]

The speed will be calculated by dividing the number of miles by minutes

So putting the values in the formula

[tex]s = \frac{\frac{11}{3}}{\frac{33}{2}}\\= \frac{11}{3} * \frac{2}{33}\\=\frac{1}{3} * \frac{2}{3}\\=\frac{2}{9}[/tex]

Hence,

The speed is 2/9 miles per minute

Answers

Answer:

Option 4: 45 units is the correct answer

Step-by-step explanation:

Let [tex]P_1[/tex] be the perimeter of Pentagon and

Let P2 be the perimeter of Triangle

So,

[tex]P_1 = 5(\frac{1}{2}x-1)\\P_2 = 3(x-5)[/tex]

In order to find the perimeter of each figure we have to put both the expressions equal so that the value of x can be found and then perimeter.

So,

[tex]P_1 = P_2\\5(\frac{1}{2}x-1) = 3(x-5)\\\frac{5}{2}x-5 = 3x-15\\\frac{5}{2}x-3x = -15+5\\\frac{5x-6x}{2} = -10\\-\frac{x}{2} = -10\\-x = -10 * 2\\-x = -20\\x = 20[/tex]

Putting x = 20 in 2nd perimeter

[tex]P_2 = 3(x-5) \\= 3(20-5)\\= 3(15)\\=45[/tex]

As both the perimeters are same, the perimeter of pentagon will also be 45 units.

Hence,

Option 4: 45 units is the correct answer

a rectangular garage has a volume of 480m^3, with a length of 12m and the width 8m.

Answers

Answer:

5 m

Step-by-step explanation:

V = l × w × h

480 = 12 × 8 × h

h = 480 ÷ 96 = 5 m

Answer:

5m

Step-by-step explanation:

Well volume is V=Bh. So you do 12 times 8= 96 thats your base. So you need to them do 480 divided by 96 which equals 5 so therefore 5 is your answer. Also just to make sure that's the right answer, do 12 times 8 times 5. That equals 480.

The volume of a right circular cone is 300 cubic inches. What is the volume, in cubic inches, of
a right cylinder that has the same base and height as the cone?

Answers

Answer:

900 cubic inches.

Step-by-step explanation:

Given the following data

Volume of right circular cone = 300in³

We know that the volume of a right circular cone is given by the formula;

[tex] V = \frac{1}{3} \pi r^{2}h[/tex]

Where;

V is the volume of right circular cone.r is the radius of the base of the right circular cone.h is the height of the right circular cone.

The volume of a right circular cylinder is given by the formula;

[tex] V = \pi r^{2}h[/tex]

Thus, multiplying the volume of the right circular cone by 3 would give us the volume of the right circular cylinder.

[tex] V = \frac{1}{3} \pi r^{2}h * 3[/tex]

Substituting into the equation, we have;

V = 300 * 3

V = 900in³

Therefore, the volume of a right cylinder that has the same base and height as the cone is 900 cubic inches.
