Solve the equation for x 120(2x − 2) = 240
sashaice [31]

Answer:

The answer is 2

Step-by-step explanation:

To find this, follow the order of operations as laid out below.

120(2x - 2) = 240 ----> Divide both sides by 120

2x - 2 = 2 ----> Add 2 to both sides

2x = 4 ------> Divide both sides by 2

x = 2

Which statements about the hyperbola are true? Check all that apply.
never [62]

Answer:

Only option A is correct.

Step-by-step explanation:

From the given figure it is noticed that the vertices of hyperbola are (0,8) and (0,-8). It is a vertical hyperbola.

It means a=8.

From the rectangle we can say that the value of b is 6.

c^2=a^2-b^2

c^2=(8)^2+(6)^2

c^2=100

c=10

The focus of a vertical hyperbola are (0,c) and (0,-c). So, the focus of hyperbola are (0,10) and (0,-10).

Therefore option A is correct.

Asymptotes of a vertical hyperbola are

y=\pm \frac{a}{b}x

y=\pm \frac{8}{6}x

y=\pm \frac{4}{3}x

Directrix of a vertical hyperbola are

y=\pm \frac{a^2}{c}

y=\pm \frac{(10)^2}{6}

y=\pm \frac{50}{3}

Only option A is correct.

Elena and her husband Marc both drive to work. Elena's car has a current mileage (total distance driven) of 7,000 and she drives
cupoosta [38]
Yes they will be equal at some point. Although Marc has more miles on his car at the current moment, Elena is adding miles at a higher rate.

Elena's car: 7000 + 21000t

Marc's car: 20000 + 11000t

To find at what time t they are equal, set these two expressions equal to each other and solve for t.

7000 + 21000t = 20000 + 11000t

13000 = 10000t

t = 1.3 years from now

Least to greatest 0.2,4/15,0.21,1/4
vladimir1956 [14]

Turn all rational numbers into fractions:

0.2 remains as it is

4/15 as a decimal is 0.26 with the 6 repeating

0.21 remains as it is

1/4 as a decimal is 0.25

Now we can organize from least to greatest as shown below:

0.2, 0.21, 0.25 (1/4), 0.2666666 (4/15)

Hope this helped!
