Given that P = (-5, 11) and Q = (-6, 4), find the component form and magnitude of vector QP.
dybincka [34]

We'll use the Pythagorean Theorem (otherwise known as the Distance Formula):

Going from Q to P, x increases by 1 and y increases by 7. Thus, the component form of QP is <1,7>, and the magnitude of this vector is √(1^2+7^2) = 5√2.

Note: this is equivalent to <1, 7>, square root of 50.

I need help with this quick question!! Extra points and I’m marking brainlist to step by step explanation
mezya [45]

Answer:

They all are solutions!

Step-by-step explanation:

3x-y=15\\6x-2y=30\\

An easy way to check this is just to substitute each pair of values into both equations:

(a) 3(6)-3=15\\6(6)-2(3)=30\\So before going any farther, we can see that A works!\\\\

(b)

3(7)-6=15\\6(7)-2(6)=30\\So B works!\\

(c)

3(8)-9=15\\6(8)-2(9)=30\\So C works!

Have a nice day!
