# Get the Math and the Points! August 2019 CC Alg I Regents #3 For this question, we need to use the Distributive Property:
2(x^2 – 1) = 2x^2 – 2
while
3x(x – 4) = 3x^2 – 12x

Michael Paul Goldenberg’s excellent comment was that the constant term must be -2 and that leads us right to the answer!  Thanks

Combine like terms and only the x^2 are combinable.
A way to check your work is to put  2(x^2 – 1) +  3x(x – 4) into Y1 and to put each multiple choice answer into Y2 and then compare to see if the tables for Y1 and Y2 are equivalent.

# Get the Math and the Points CC Alg I Aug 2019 Regents #2 A function is defined as no repeating x values.  Please take a look above and see which table has unique x values.  That’s it — 2 points 🙂

# Get the Math and the Points! Aug ’19 Regents CC Alg I #1 This is actually a reading question!
If x = 0, it will still cost 250
If x = 1, the cost should be 273 (250 + 23)
If x = 2, the cost should be 296 (250 + 23 + 23)
Try these values for x and you will find the answer 🙂

# Get the Math and the Points! CC Alg I Jan 2019 #3  Rational means that the number can be written as exact number or with a repeating decimal. Which of the above is either a terminating or repeating decimal?

# Jan 2019 Algebra I Regents #2 This question asks students to substitute or plug in -3 for x so
g(-3) = -2(3)^2 + 3(-3) being careful about order of operations 🙂

Students can check their work by using the TI-84
