Algebra C and C Geometry

The table is a proportionality table, then x =

• 10

• 35

• 1.6

Was a French mathematician, lawyer, and advisor to Kings Henry III and IV of France. He made significant advances in Algebra, and first introduced the use of letters to represent variables.

• Joseph-Louis Lagrange (1736 – 1813)

• Leonardo da Vinci (1452 – 1519)

• Fibonacci (1175 – 1250)

• François Viète (1540 – 1603)

What is step 4

• Substitution property (simplify)

• Addition property of equality

• Subtraction property of equality

This student made an error with the disruptive property. What did s/he do wrong?

• You can't drop down a -16; You need to keep it positive

• You should only multiply the -2 & 8m; the 8 should stay the same

• You need to multiply -2 to both parts inside the parenthesis; -2*8m is -16m and -2*8 is -16

• You should divide -2 from both sides first

This student subtracted 2 from both sides of the equation. What should s/he have done?

• Nothing; This is correct

• S/He should have added a -2 to both sides

• S/He should have added 2 to both sides

• Subtracted 2x instead of 2

What error(s) did this student make?

• Did not combine like terms

• Needed to add 2x instead of subtract

• Should not use inverse operations on the same side of the equal sign

• No errors; the student is correct

Did this student solve the problem correctly? Type YES or NO

This student's mistake is circled in yellow. What should s/he put here.

What is the name given to the point (0 , 7)?

• just a plain point

• root

• y-intercept

• vertex

Does the graph represent a min/max/both/neither?

• A) Minimum

• B) Maximum

• C) Both

• D) Neither
