The system of equations have 2 solutions

<h3>How to determine the number of solutions?</h3>

The system of equations is given as:

-1/3x² = 5/6 + 1/3y²

5y² = 25/2 - 5x²

Next, we plot the graph of the system of equations.

From the attached graph, the equations intersect at two points

Hence, the system of equations have 2 solutions

What number should be added to 7/12 to get 4/15?​
DENIUS [597]

Answer:

Step-by-step explanation:

Let the number = x.

We are trying to find out what number (x) we would need to add to 7/12 to get 4/15

\frac{7}{12}  + x = \frac{4}{15}

Subtract 7/12 from both sides.

x = \frac{4}{15}  - \frac{7}{12}

We need to make the denominators of the fractions the same.

\frac{4}{15}  = \frac{16}{60}

\frac{7}{12}  = \frac{35}{60}

So,

x = \frac{16}{60}  - \frac{35}{60}  = -  \frac{19}{60}

spin [16.1K]

Answer:800

Step-by-step explanation:

Mean(\mu )=\$ 4300

and P(X>6140)=0.0107

P(X>x_0)=0.0107

P\left ( \frac{X-\mu }{\sigma}

P\left ( z

\frac{x-\mu }{\sigma}=InvNormal(0.9893)

Using Z table to get InvNormal(0.9893)=2.30

\frac{6140-4300}{\sigma}=2.30

\sigma =\frac{6140-4300}{2.30}=800

Kelly saves $5 every week. Which expression represents the amount of money, in dollars, Kelly will save in w weeks
Svetradugi [14.3K]
Let's say x is the amount of money Kelly saves.  We do not know how many weeks she is saving.  If she was saving for 2, then the equation would be x=5(2).  However, she is saving by w weeks, so the equation is x=5w.

Find the radius. Round to the nearest tenth.
Arlecino [84]

Answer:

Step-by-step explanation:

V = 1/3 * pi * r^2 * h

r = ?

pi = 3.14

h = 17 cm

3*V = pi * r^2 h = r^2    Divide by pi

3*V/pi = r^2 h  = r^2     Divide by h

3*V/(pi*h)         =r^2      Take the square root of the left to get just  r

sqrt(3*V/(pi*h))  = r         Now solve the equation.

sqrt(3*538.25 /(3.14*17)) = r

sqrt(1614 / 53.38) =

r = sqrt(30.24)

r = 5.493
