What is the answer to: -1.5x -3.1 < 5.5

Mathematics
1 answer:
liraira [26]3 years ago
6 0

For this case we have the following expression:

-1.5x-3.1

Adding 3.1 to both sides of the inequality:

-1.5x

Dividing between -1.5 on both sides of the inequality, keeping in mind that the sign changes direction:

x> \frac {8.6} {- 1.5}\\x> -5.73333

Answer:

x> -5.73333

A car is driving 90 kilometers per hours how far in meters does it travel in 3 second
serious [3.7K]

Answer:

<u><em>I hope it  will work</em></u>

Step-by-step explanation:

as given

speed = v = 90 km/hr    convert to meter and sec we get

v =( 90 *1000 meter)/(3600 sec)

v=25 m /sec

as given t= 2 sec so

v=s/t

s= v*t

s=25*2

s=50 meter

if its help-full hit the stars and brain list it thank-you

An expression is shown below:
kirza4 [7]

The factored expression is:

3y(x^3 + 4x - 3x^2 - 12)

------------------------

To factor the expression:

  • First, we need to find the greatest common factor of the numeric and symbolic coefficients.
  • Then, we divide each term of the expression by it's gcf.

------------------------

The expression is:

3x^3y + 12xy - 9x^2y - 36y

------------------------

The numeric coefficients are: 3, 12, 9, 36

The gcf of the numeric coefficients is:

3 - 12 - 9 - 36|3

1 - 4 - 3 - 12

The gcf of the numeric coefficients is 3, as 3 is the only number by which 3, 12, 9 and 36 are all divisible.

------------------------

The symbolic coefficients are: x^3y, xy, x^2y, y

The only common term is y, so y is the gcf of the symbolic coefficients.

------------------------

The gcf of the entire expression is the multiplication of the gcfs of the numeric and of the symbolic coefficients, so it is 3y.

Now, to factore the expression:

3x^3y + 12xy - 9x^2y - 36y = 3y(\frac{3x^3y}{3y} + \frac{12xy}{3y} - \frac{9x^2y}{3y} - \frac{36y}{3y}) = 3y(x^3 + 4x - 3x^2 - 12)

The factored expression is:

3y(x^3 + 4x - 3x^2 - 12)

(1 point) Find an equation of the largest sphere with center (5,3,5)(5,3,5) and is contained in the first octant. Be sure that y
Hoochie [10]

Answer:

x^2+y^2+z^2-10x-6y-10z +50 =0

Step-by-step explanation:

Given that a sphere is contained in the first octant

Centre of the sphere is given as (5,3,5)

Since this is contained only in the first octant radius should be at most sufficient to touch any one of the three coordinate planes

When it touches we can get the maximum sphere

We find that y coordinate is the minimum of 3 thus radius can be atmost 3 so that then only it can touch y =0 plane i.e. zx plane without crossing to go to the other octants.

Hence radius =3

Equation of the sphere would be

(x-5)^2 +(y-3)^2+(z-5)^2 = 3^2\\x^2+y^2+z^2-10x-6y-10z +50 =0

Solve for x, and refer to the attached image.
AVprozaik [17]

Answer:

x=8

Step-by-step explanation:

7+5x

so basically what you have to do is take the 7 and subtract from both sides

so like this: 7-7 is 0 so that cancels then 47-7 is 40

then you take 5x and divide 40 by 5

so x=8

hope this helped!
