Write the slope-intercept equation for the line with
y-intercept of -3/4 and slope of 5
y=5x-3/4
100
Is this a function? (Only one try!)
No! It fails the vertical line test (has multiple y values for a given x value)
100
What point solves this linear system?
(4,3)
100
Simplify:
(x^3)^4
x^12

What percent of a watermelon is water? (Guess within +/- 2%)
A watermelon is 96% water!
200
Solve for k:
-5k+3<=18
k>= -3
200
What is the domain of this relation?
(-7, 0, 1, 4, 5)
200
What point solves this system of equations?
x=y+2
y=5
(7,5)
200
Simplify:
4x^2y^4*x^3y^3
4x^5y^7
200
How many millions of pounds of watermelons were grown in the US in 2020? (Guess within +/- 5 million)
38 million pounds (on over 100,000 acres of land!)
300
Evaluate
6m^2+m if m=3
57
300
Is this relation a function? (only one try!)
Yes! Every x value (input) has only one y value (output)
It's ok if one y value has multiple x values!
300
What point solves this system of equations?
3x-y=5
y=x+7
(6,13)
300
Simplify:
(4u^3v^4)/(2uv^2)
2u^2v^2

AUDIO CLUE! In what year was this song originally released? (Guess within +/- 5 years)
400
Solve for x:
px+2x=q
x=q/(p+2)
400
f(x)=|x|+3x^2
f(-2)=?
f(-2)=|-2|+3(-2)^2
=2+3*4=2+12=14
400
What point solves this system of equations?
2x+3y=4
-2x+2y=6
(-1,2)
400
Simplify:
(-3x^4y^-3)/(-x^-3y^-2)
(3x^7)/y
400
1 + (1 x 0) + 1
= 1 + 0 + 1 = 2
500
Solve for t:
|7-3t|=1
(Hint: two solutions!)
t={2,8/3}
500
