In the equation 5x-2=-x-20, What is the value of x?<br> a. 2<br> b. -1<br> c. -3<br> d. -2
mestny [16]

Answer:

C choice.

Step-by-step explanation:

5x - 2 =  - x - 20 \\

First, we move the same terms to the same side.

5x + x =  - 20 + 2 \\ 6x =  - 18

Then we move 6 to divide - 18.

x =  \frac{ - 18}{6}  \\ x =  - 3

Ierofanga [76]

Answer:

A

Step-by-step explanation:

Sum the product of the components in the first row of A with the corresponding components of the first column in B

Repeat this with the components in the second row of A with the corresponding components of the second column in B, that is

AB

= \left[\begin{array}{ccc}2&1\\3&4\\\end{array}\right] \left[\begin{array}{ccc}3&1\\5&2\\\end{array}\right]

= \left[\begin{array}{ccc}2(3)+1(5)&2(1)+1(2)\\3(3)+4(5)&3(1)+4(2)\\\end{array}\right]

= \left[\begin{array}{ccc}6+5&2+2\\9+20&3+8\\\end{array}\right]

= \left[\begin{array}{ccc}11&4\\29&11\\\end{array}\right]  → A
