What expression could be used to represent "12 less than triple a number , x" ? Explain.

2 answers:

3x - 12

Triple a number would be 3x instead of x cubed as it is not asking for a number multiplied by itself three times.

-12 is the second half as since you don’t know whether or not the variable will be larger or smaller than the constant, it is safer to put it on the other half.

Thus, this equation fills in the worded format.

Hope this helps!

12-3x because 12 less than means 12- and tripe a number is 3x which is 12-3x or -3x+12

Solve for x:<br> 6x + 6 = 3x – 21

Volgvan

Answer:

x = -9

Step-by-step explanation:

6x + 6 = 3x – 21

Subtract 3x from each side

6x-3x + 6 = 3x-3x – 21

3x+6 = -21

Subtract 6 from each side

3x+6-6 = -21-6

3x = -27

Divide by 3

3x/3 = -27/3

x = -9

What is the matrix for y+x=4 and 2x-3y=3

andrew11 [14]

Given equations:

x+y = 4;
2x-3y = 3;

Matrix form would be:

$\left[\begin{array}{cc}1&1\\2&-3\end{array}\right] \left[\begin{array}{c}x\\y\end{array}\right] = \left[\begin{array}{c}4\\3\end{array}\right]$

1+cos2A /1-cos2A=cotA.cotA

Allisa [31]

Answer:

See Explanation

Step-by-step explanation:

$formulae \: to \: be \: used : \\ \cos 2 \theta = 2 { \cos}^{2} \theta - 1 \\ and \\ \cos 2 \theta = 1 - 2 { \cos}^{2} \theta \\ \\ now \: let \: us \: prove \: the \: given \: trigonometrical \: \\ identity. \\ \\ \frac{1 + \cos2A}{1 - \cos2A} = \cot \: A. \cot \: A \\ LHS = \frac{1 + \cos2A}{1 - \cos2A} \\ \\ = \frac{1 +2 { \cos}^{2} A- 1 }{1 - (1 - 2 { \sin}^{2} A)} \\ \\ = \frac{1 +2 { \cos}^{2} A- 1 }{1 - 1 + 2 { \sin}^{2} A} \\ \\ = \frac{2 { \cos}^{2} A }{2 { \sin}^{2} A} \\ \\ = \frac{{ \cos}^{2} A }{ { \sin}^{2} A} \\ \\ = { \cot}^{2} A \\ \\ = { \cot} A .{ \cot} A \\ \\ = RHS \\ \\ hence \: proved.$

Determine if the two triangles are congruent.

stiks02 [169]

Answer:

SAS

Step-by-step explanation:

The two triangles share a side, so that would be reflexive to show that side is congruent. Also, keep in mind that all right angles are congruent! The picture already tells us that the two outer side are congruent. So in conclusion, the two angles are congruent by SAS.

Hope this helps! :)
