Answer:

x = 15

Step-by-step explanation:

collect like terms

6x+4x= -18-12

2x= -30

divide through by 2

2x/2= -30/2

x = -15

therefore

x = -15

Answer:

X = -15

Step-by-step explanation:

6X +12 = 4X -18

Subtract 4X from both sides

2X +12 = -18

Subtract 12 from both sides

2X = -30

Divide both sides by 2

X = -15

So basically just have the unknown on one side and normal numbers on the other. Make sure you do the same thing on both sides.

The tires on your bicycle have a radius of 14 inches. How many rotations does each tire make when you travel 900 feet? Round you
Nezavi [6.7K]

Around  150 rotations

I rounded the radius to feet which is 1 foot. Then you have to get the diameter which is 1x2=2. The diameter is 2 feet. Now for the circumference, we multiply 2 by 3.14(which is pi). The answer to that is 6.28, and since we are rounding it, we get 6 feet. However, we are traveling 900 feet. Divide 900 by 6 and get 150.

Determine the domain of the function (f o g)(x) where f(x)= 3/x+2 and g=5/x.
vitfil [10]

Answer:

The Domain is all real values of x except x = 0 and x = -2.5.

Step-by-step explanation:

I am assuming that f(x) = 3/(x + 2).

(f o g)x is found by substituting  5/x for the x in 3/(x + 2).

(f o g) x = 3/ ( 5/x + 2)

= 3 / ( 5+2x) / x

= 3x / (5 + 2x).

When finding the domain you  first check for values of x which make g(x) undefined then values of x which make (f o g)(x) undefined.

x = 0 makes  g(x) = 5/0 so it is undefined and  x = -2.5 makes g o f undefined also.

Use the Intermediate Value Theorem to show that there is a root of the given equation in the specified interval. ex = 3 − 2x, (0
raketka [301]

Answer:

f(0)=-2\\f(1)=e-1

Step-by-step explanation:

According to intermediate value theorem, if a function is continuous on an interval [a,b], and if k is any number between f(a) and f(b), then there exists a  value, x=m, where a, such that f(m)=k

In the given question,

Intermediate Value Theorem is used to show that there is a root of the given equation in the specified interval.

Here,

f(x)=e^x-3+2x

Put x=0

f(0)=e^0-3+2(0)=1-3+0=-2

Put x=1

f(1)=e^1-3+2(1)=e-3+2=e-1
