Answer:

x\geq 90.

Step-by-step explanation:

Let x represent the number.

We have been given a sentence. We are supposed to translate our given sentence into an inequality.

We are told that the number is at-least 90. This means that our required number is greater than on equal to 90.

We can represent this information in an inequality as:

x\geq 90

Therefore, our required inequality would be x\geq 90.

These two matrices are unable to be added due to dimensional mismatch? True, false, both, unable to answer with the info given
Hoochie [10]

Answer:

false

Step-by-step explanation:

\left[\begin{array}{c}-4\end{array}\right] +\left[\begin{array}{c}7\end{array}\right] =\left[\begin{array}{c}3\end{array}\right]

Both of the matrices are 1 x 1 ("one by one"), so they can be added to produce a 1 x 1 matrix.

To add (or subtract) two matrices, they must be the same size.

(m x n) + (m x n) = (m x n)

m x n  means a matrix has  m  rows and  n  columns.  Dimensions are always named in that order:  rows, then columns.

Solve the triangle for all missing sides and angles
Mama L [17]

Answer:

x = 35

C = 18.92

A = 71.07

Step-by-step explanation:

x)

Use the Pythagorean theorem to find the unknown side.

a^{2} +b^{2} =c^{2} \\\\\\12^{2} +x^{2} =37^{2} \\x^{2} = 37^{2}-12^{2}\\x=35

For Angle C

The angle C can be found using the inverse sine function.

C=arcsin(opp/hyp)

C=arcsin(12/37)

C=18.92

For Angle A

The sum of all the angles in a triangle is 180 degrees.

A + 90 + 18.92 = 180

A = 71.07

What are the steps to factoring 6x^2+5x-6
Tanya [424]

Answer:

there is only one easy way to sole this

using quadratic equation

\frac{ - b + \sqrt{ {b}^{2}  - 4ac}   }{2a}  \\ and \: \:  \\ \frac{ - b  -  \sqrt{ {b}^{2}  - 4ac}   }{2a}

Step-by-step explanation:

a=6 b=5 c=-6

and by applying it to the equation you will get

x=0.66 and x=-1.5
