First, add -7 to both sides of the equation:

$9x = 0$

Dividing by 9 gets us:

$x = 0$

The answer is x = 0.

Hello!

Explanation:

First, you had to do is add by 7 from both sides of an equation.

$9x-7+7=-7+7$

Then, simplify.

$-7+7=0$

$9x=0$

Next, you divide by 9 from both sides of an equation.

$\frac{9x}{9}= \frac{0}{9}$

Finally, simplify.

$9/0=0$

So therefore, the final answer is x=0

Hope this helps!

Thanks!

What’s the angle of cda

Anastaziya [24]

Answer:

∠ CDA = 32.3°

Step-by-step explanation:

See the given figure attached to this answer.

Draw perpendiculars from B and C on AD which is BE and CF.

Now, Δ ABE is a right triangle and AE² = AB² - BE² = 7.5² - 6² = 20.25

⇒ AE = 4.5 cm

Now, DF = AD - EF - AE = 24 - 10 - 4.5 = 9.5 cm {Since BC = EF}

And CF = BE = 6 cm.

Now, Δ CFD is a right triangle and

$\tan \beta =\frac{CF}{FD} = \frac{6}{9.5} = 0.6315$ {Where β = ∠ CDA}

⇒ $\beta = \tan^{-1} (0.6315)=32.27$ Degree.

So, ∠ CDA = 32.3° {Correct to one decimal place} (Answer)

raketka [301]

Answer:

523.6 cm^3

Step-by-step explanation:

We know the diameter is 10. The radius is half the diameter, so 10/2=5.

Knowing the radius is 5, we just need to plug it into the formula.

Volume=(4/3)pi5^3

≈523.6

Answer:523.6 cm^3

70 POINTS! PLEASE HELP! Explain the difference between the following equation formats: Slope-Intercept, Point-Slope and Standard

katrin2010 [14]

Answer and Step-by-step explanation:

1. slope intercept

2. point-slope form

3. standard

Explanation:

1. A slope intercept form equation is when it's set up as y = m x + b

m = slope

b = y-intercept

2. A point-slope form is when a line passes through a point

and the equation is set up as y −b = m ( x−a)

m = slope

(a, b) A point that the line passes through

3. standard lope form is when the equation is set up as

Ax + By = C

PIUWawilities

blondinia [14]

Answer:

23.44%

Step-by-step explanation:

The probability of getting a 4 on the first 2 throws and different numbers on the last 5 throws = 1/6 * 1/6 * (5/6)^5

= 0.01116

There are 7C2 ways of the 2 4's being in different positions

= 7*6 / 2 = 21 ways.

So the required probability = 0.01116 * 21

= 0.2344 or 23.44%.
