Real Numbers and Scientific Notation
What is the number 1,000,000,000 written as in scientific notation?
What is the y-intercept in this equation?
Y = -4x + 6
B = 6
Solve for X in this equation: X^2 = 121
(Remember how squares can have multiple answers!)
The SBC is making Valentines Day grams for our school! They will use 25 lollypops per class (c) and a total of 50 pieces of paper. What would the equation from this scenario be in -
Y = mx + b form?
Y = 25c + 50
What is the number 0.000000018 written as in scientific notation? (Remember moving decimals effects the sign of the exponent!)
1.8 x 10^-8
Given this Equation -
Y = -17x + 3.5
Will the line be slopping up or down and why?
The line will slope down because the slope -17 is negative.
Given these two points on a line -
p1(2, 2) and P2(4, 8)
Calculate the slope using Slope Formula
m = (Y2 - Y1) / (X2 - X1)
m = (8 - 2) / (4 - 2)
m = 6/2
m = 3
Solve this System of Equations by substitution:
X + Y = -9
Y = 2x
X + Y = -9
Y = 2x
X + (2x) = -9
3x = -9
X = -3
