PLEASE HELP! Is my answer correct?

Answer:

Our answer is [tex]x=9[/tex]

Step-by-step explanation:

First we will rearrange so we have to divide by 7.

[tex]\frac{x}{3}= \frac{2x+3}{7}[/tex]

Now we will cross multiply.

So...

[tex]x*7 \\3*2x+3[/tex]

Our new equation will look like:

[tex]7x=6x+9[/tex]

Now we have to isolate x.

So we have to subtract 6x from both sides.

[tex]7x-6=1x[/tex]

and

[tex]6x-6x=0[/tex]

Our new equation is:

[tex]1x=9[/tex]

Now divide.

Our answer is [tex]x=9[/tex]

Hope this helped!

Answer:

AC

Step-by-step explanation:

We know that a diameter of a circle is any straight line segment that passes through the center of the circle such that whose endpoints lie on the circle. It is also be known as the longest chord of the circle.

In the given figure we can see that only AC and BE are the  line segments that pass through the center of the circle such that whose endpoints lie on the circle.

Answer:

(6x - 1)(6x + 1)

Step-by-step explanation:

36x² - 1 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

Thus

36x² - 1

= (6x)² - 1²

= (6x - 1)(6x + 1)

Answer:

36 miles

Step-by-step explanation:

(Imagine a huge triangle on a perfectly open space-- not with streets or houses or cornfields.)

The dimensions of the two sides given are multiples of a classic Pythagorean Triple: 3, 4, 5.    [tex]3^{2} + 4^{2} = 5^{2}[/tex]  

9 is 3x3, 12 is 3x4 so the remaining side would be 3x5  15

Add those 3 sides to get the total distance, 36 miles.

Answer:

16400 in ^2

Step-by-step explanation:

For area, we multiply by the scale factor squared

area 2 = sf^2 * area 1

Since the scale factor is 10,

area 2 = 10^2* 164

           = 100*164

           = 16400

Answer:

16,400 in²

Step-by-step explanation:

Ratio of Areas = (Ratio of sides)²

A/164 = 10²

A/164 = 100

A = 16400

Answer:

1/12

Step-by-step explanation:

Since all are equally likely, each outcome has a probability of 1/12.

P(9) = 1/12

Answer:

1/12

Step-by-step explanation:

The probability of rolling a nine is given by the number of good outcomes over the total outcomes

P(9) = number of 9's / total

       =1/12

Step-by-step explanation:

[tex] \frac{f}{5} - ( - 13) = 12[/tex]

[tex] \frac{f}{5} + 13 = 12[/tex]

[tex] \frac{f}{5} = 12 - 13[/tex]

[tex] \frac{f}{5} = - 1 [/tex]

Now cross multiply

Therefore f = -5

Answer:

f= -5

Step-by-step explanation:

f/5-(-13)=12

remove the parenthesis and replace the negative with a positive.

f/5+13=12

multiply all by 5

f+65=60

move constant to the right

f=60-65

subtract 60 to 65

f= -5

Answer:

- 85

Step-by-step explanation:

The n th term of a geometric series is

[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]

where a is the first term and r the common ratio

1[tex](-2)^{n-1}[/tex] ← is the n th term of a geometric series

with a = 1 and r = - 2

The sum to n terms of a geometric series is

[tex]S_{n}[/tex] = [tex]\frac{a(r^{n}-1) }{r-1}[/tex]

    = [tex]\frac{1((-2)^{8}-1 }{-2-1}[/tex]

    = [tex]\frac{256-1}{-3}[/tex]

    = [tex]\frac{255}{-3}[/tex]

Ratio or outcome maybe?

Step-by-step explanation:

To find the product with unknown values of variables, multiply the terms and equate the value to the given product.

[tex](7d^{2} - 3d + g)(3d^{2} + hd - 8)[/tex] = [tex]21d^{4} + 7hd^{3} - 56d^{2} - 9d^{3} - 3hd^{2} + 24d + 3gd^{2} + ghd - 8g[/tex]

[tex](7d^{2} - 3d + g)(3d^{2} + hd - 8)[/tex]     = [tex]21d^{4} + (7h-9) d^{3} + (3g-56-3h)d^{2} + (24+gh)d -8g[/tex]   ... (1)

Comparing eq(1) to the product given in question,

-8g = -1

g = 2

24 + gh = 14, sub g =2,

24 + 2h = 14

h = -5

Answer:

34.3 meters

Step-by-step explanation:

The generic equation for a movement with constant acceleration is:

S = So + Vo*t + (a*t^2)/2

Where S is the final position, So is the inicial position, Vo is the inicial speed, a is the acceleration and t is the time.

If we compare with our equation (where x is the time and f(x) is the final distance), we have that:

So = 34.3

Vo = 29.4

a = -9.8

So we have that the inicial position (So) of the object is 34.3 meters

Answer:

18.02 cm

Step-by-step explanation:

A diagonal makes a rectangle into two right triangles. So if we use the Pythagorean theorem we can find the hypotenuse which is the diagonals.

Remember, because we know the length and width, we know the two sides.

10^2 + 15^2 = c^2

100+225 = c^2

325 = c^2

18.027 ≈ c

We can use the Pythagorean theorem to solve for the diagonal. The diagonal is the same as the hypotenuse of a triangle.

Pythagorean Theorem: a² + b² = c²

Now, solve for the diagonal.

(10)² + (15)² = c²

100 + 225 = c²

325 = c²

√325 = √c²

18.0277... = c

Round if necessary.

18.0277... = 18.03

Therefore, the diagonal of the rectangle is approximately 18.03cm.

Answer:

[tex]V=35.3\ m^3[/tex]

Step-by-step explanation:

-Given the cone's height is 9.1m and the Circumference is 12.1

#We use the circumference formula to calculate the radius:

[tex]C=2\pi r\\\\12.1=2\pi r\\\\r=\frac{12.1}{2\pi}=\frac{6.05}{\pi}\ cm[/tex]

-The volume of the cone using the radius above can then be calculated as follows:

[tex]V=\pi r^2\frac{h}{3}\\\\=\pi\times(\frac{6.05}{\pi})^2\times \frac{9.1}{3}\\\\\\=35.3\ m^3[/tex]

Hence, the cone's volume is [tex]35.3\ m^3[/tex]

Answer:

(2,5)

Step-by-step explanation:

If you are flipping a point over the x-axis, multiply the y coordinate by -1, if you are flipping something over the y-axis, multiply the x coordinate by -1.

The coordinates of point B are (2,5)

When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.

If you study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.

Given that  coordinates of point A on a grid are (2, -5). Point A is reflected across the x-axis to obtain point B.

Since flipping a point over the x-axis, then we have to multiply the y coordinate by -1,

And ifyou are flipping something over the y-axis, then we have to multiply the x coordinate by -1.

Therefore, the point B are (2, _5_).

Answer:

f(6)=-29

Step-by-step explanation:

f(6)=-5(6)+1

f(6)=-30+1

f(6)=-29

The value of f(6) is -29.

Given,

f(x)= -5x+1

We need to find f(6).

A function is denoted by f(x) and the point can be a value of x.

The x values are called domain and f(x) is called the output.

Example:

f(x) = x + 2

At x = 1

f(1) = 1 + 2 = 3.

Find f(x) = -5x + 1 at x = 6.

f(x) = -5x + 1

f(6) = - 5 x 6 + 1

     = -30 + 1

     = -29

This means the function f(x) is -29 at x = 6.

Thus the value of f(6) is -29.
