Ch 5 review

which is not a non-linear expression

• 2x² + 3y - 4
• 6y - 8x x 4 + 4
• 15y² x 16x
• 17y + 1²

What are like terms ?

• The Numerical Factor of a term that contains a variable ..
• The Price of Chips
• Terms That Contain the same Variables Raised to the same power
• Each Number in a Sequence

(5x + 6 ) + ( x + -10 )

• 0
• 4x - 16
• 6x-4
• 5x + 16x

What are constants?

• Something I don't care about
• A number with a variable
• A number without a variable
• A negative number with a variable

How many constants are in 4(1x+-1x)+(1-1x)+(1+-1x)+(3x+-1)

• 3

• 4

• 5

• 6

a type of expression that contains a variable or variables?

• i dont know
• algebraic
• a term
• adding numbers

like terms

• cant remember
• terms that have the same numbers
• variable is the number
• terms that have identical variable parts 4y and 3y

(5x-9)-(2x-7)

• 7x-2
• 3x-2
• I don't even know !!
• 2-3x

What is the definition of linear expressions?

• When you add the variables
• How far you jump
• The distance from zero
• An algebraic expression in which the variable is raised to the first power.

Exponents

• Examples: 32 + 4x2 + to the third power of 5 =26
• How many numbers is in the problem.
• How many times to use that number in multiplication
• How many times to use that number in division.
