Hey there,

The first thing you have to do is add -1y to both sides:
1x + 1y = 8
+-1y +-1y

You should get: 1x = -1y+8

So your total answer is: 1x = -1y+8

~~I hope I helped and let me know if you need anything else~~

Which is the most appropriate answer for this problem? Kara bought a sweater for $16.98, a shirt for $14.99, and jeans for $21.9

liq [111]

60-(16.98+14.99+21.95)=change=60-53.92=6.08

change is $6.08

-3(-5)-3y=-6 find the value of y

julia-pushkina [17]

-3 (-5) - 3y = -6

15 - 3y = -6

-3y = -6 + (-15)

-3y = -21

y = -21 / -3

y = 7

The value of y is 7.

For the vectors Bold uequalsleft angle negative 8 comma 0 comma 1 right angleand Bold vequalsleft angle 1 comma 3 comma negative

trapecia [35]

Answer:

Step-by-step explanation:

Given that there are two vectors U = (-8,0,1)

V = (1,3,-3)

To find projection of u on V and also projection of V on U

First let us find the dot product U and V

U.V = $-8(1)+0(3)+1(-3)\\= -11$

Projection of U on V = $\frac{U.V}{|V|} \\=\frac{-11}{\sqrt{1+9+9} } \\=\frac{-11}{\sqrt{19} }$

Similarly projection of V on U

= $\frac{U.V}{|U|} \\=\frac{-11}{\sqrt{64+0+1} } \\=\frac{-11}{\sqrt{65} }$
