Answer:
multiply by 3 and divide by 2 to get 6x -y = 12.
Step-by-step explanation:
A standard form equation has mutually prime integers for coefficients, and the leading one is positive. We can get that here by multiplying by 3 (to eliminate the denominator) and dividing by 2 (to remove that common factor). The result is ...
4(3/2)x -(2/3)(3/2)y = 8(3/2)
6x -y = 12

Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
<span>Equation at the end of step 2 :</span> 6x2 - x - 4 = 0 <span>((2•3x2) - x) - 4 = 0
</span><span>Step 2 :</span>Trying to factor by splitting the middle term
<span> 2.1 </span> Factoring <span> 6x2-x-4</span>
The first term is, <span> <span>6x2</span> </span> its coefficient is <span> 6 </span>.
The middle term is, <span> -x </span> its coefficient is <span> -1 </span>.
The last term, "the constant", is <span> -4 </span>
Step-1 : Multiply the coefficient of the first term by the constant <span> <span> 6</span> • -4 = -24</span>
Step-2 : Find two factors of -24 whose sum equals the coefficient of the middle term, which is <span> -1 </span>.

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.
