We know that
If the scalar product of two vectors<span> is zero, both vectors are </span><span>orthogonal

</span><span>A. (-2,5)
</span>(-2,5)*(1,5)-------> -2*1+5*5=23-----------> <span>are not orthogonal 

</span><span>B. (10,-2)
</span>(10,-2)*(1,5)-------> 10*1-2*5=0-----------> are  orthogonal 

<span>C. (-1,-5)
</span>(-1,-5)*(1,5)-------> -1*1-5*5=-26-----------> are not orthogonal 

<span>D. (-5,1)
</span>(-5,1)*(1,5)-------> -5*1+1*5=0-----------> are  orthogonal 

the answer is 
B. (10,-2) and D. (-5,1)  are  orthogonal  to  (1,5)

Solve for X<br><br> 4X-(9-3X)=8X-1
Nataliya [291]
4x - (9 - 3x) = 8x - 1

4x - (9) - -(3x) = 8x - 1

4x - 9 + 3x = 8x - 1

7x - 9  = 8x - 1        (-8x from each side)

-x - 9 = -1                (+9 to each)

-x = 8                     (divide -1 from each side)

x = -8

If 15% of 4x is 20 less than x, what is the value of x?
Bess [88]

The sentence "15% of 4x is 20 less than x"

translates to    0.15 • (4x)  = x – 20

Solving that…

    0.15(4x) = x - 20           multiplipy 0.15•4

          0.6x = x - 20           subtract x from both sides

         -0.4x = - 20              divide both sides by -0.4

                x = 50
