## I am actively going for an 800 and am scoring high 600’s very low 700’s right now.

Mike I seem to be having an issue. I am actively going for an 800 and am scoring high 600’s very low 700’s right now. My biggest issue is misreading, poor arithmetic, and at times, a lack of motivation. I seem to give up on certain solutions only to return afterwards and figure it out like it’s nothing. Is this a sign of burn out? I am taking 2-3 practice tests for math a day, and I feel worn out sometimes. My other disturbing trend is getting a ton of easy’s wrong…I mean got #1 wrong once….

## If x and y are numbers such that (x+9)(y-9)=0 what is the smallest possible value of X^2 + y^2?

Hi Mike, sorry for asking questions so frequently. I’m on my 16th practice test now and I am amazed to find something new everytime. Anyway…

If x and y are numbers such that (x+9)(y-9)=0 what is the smallest possible value of X^2 + y^2

A 0
B 9
C 18
D 81
E 162

I got E when I did this but the answer is 81.Why?

## In the xy plane above, f and g are functions defined by f(x)=abs[x] and g(x)=-abs[x] + 3 for all values x. What is the area of the shaded region bounded by the graphs of the two functions?

Hi mike! This question is from the May 2015 SAT.

In the xy plane above, f and g are functions defined by f(x)=abs[x] and g(x)=-abs[x] + 3 for all values x. What is the area of the shaded region bounded by the graphs of the two functions?

## If h is 6 less than t in the equations above, then g is how much less than s?

s=t
g=h-5

If h is 6 less than t in the equations above, then g is how much less than s?

A)1
B)5
C)6
D)9
E)11

## For all numbers x and y, let x # y be defined by x # y= |x^2-y^2| + 2…

I’m just going to make up a symbol for better visualization. The symbol will look like this: #

For all numbers x and y, let x # y be defined by x # y= |x^2-y^2| + 2. What is the smallest possible value of x # y?

This was a 2/5 on the difficulty scale yet I somehow didn’t understand this and still got it wrong. I tried to do some weird algebra that got me nowhere so I moved on. Funny thing this was the only question I got wrong in the section.
