Hello! The question is in the picture and getting help would be greatly appreciated!

1. y=13

2. y= -6

Step-by-step explanation:

hello there!

in no.1 we should ignore the sign of 1st +

and do the further process

in no.2 we need to multiply sign (-) from each down digits.. and after that ..we can do the further process

hope it helps!

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
