Given the vectors u= <2, 1> and v= <5, 4>, determine the components of a vector represented by 2u - 3v
kati45 [8]

Answer:

C.) <-11, -10>

Step-by-step explanation:

Let's define how to work with vectors.

For two vectors:

V = <a, b>

W = <c, d>

The product of a scalar k and a vector is given by:

k*V = k*<a, b> = <k*a, k*b>

And the sum (or difference) of two vectors is given by:

V ± W  = <a, b> ± <c, d> = <a ± c, b ± d>

Now that we know this, we can solve the problem.

Here we have the vectors:

u = <2, 1>

v = <5, 4>

then:

2u - 3*v = 2*<2, 1> - 3*<5, 4>

             = <2*2, 2*1> - <3*5, 3*4>

             = <4, 2> - <15, 12>

             = <4 - 15, 2 - 12>

             = < -11, -10>

Then the correct option is C.

What are the solutions of 2x^2+3x-7=x^2+5x+39
sveticcg [70]

Answer:

{x}^{2}  - 2x - 46

Step-by-step explanation:

{2x}^{2}  + 3x -  7 =  {x}^{2}  + 5x + 39

Collect like terms

{2x }^{2}  -  {x}^{2}  + 3x  - 5x - 7 - 39

{ x}^{2}  - 2x - 46
