Transformations
Melanie wants to create a pattern using a transformation that will change the orientation of a figure but not the orientation of the vertices. What transformation should she use?
Rotation
Rex deposited $900 into an account that earns 4% simple interest. How many years will it take for the value of the account to reach $1,800?
25 years
What is b?
1/2b + 8 - 10 = 6
B=16
Coefficient (tell me the definition)
Number in front of a variable (multiplying the variable)
Image
Shape or figure after a transformation; the new figure
What algebraic representation shows the effect that a reflection over the x-axis will have on the coordinates of a figure?
(x,-y)
Sage plans to start depositing $175 each month into an interest earnings savings account. According to her online calculations, the balance of the savings account in 5 years will be about $12,100. How much of the final balance will come from interest earned?
$1,600
What is W?
18-5w + 7w - 4 = 28
W=7
Fixed value, or a number on its own. (tell me the word that goes with the definition)
Constant
Total Surface Area
Total area of the faces and bases of a three-dimensional object
Say the correct algebraic representation for a translation 8 units right and 4 units down.
(x+8, y-4)
Nadia deposited $3,000 into an account that earns annual simple interest. After 6 years, she had earned $990 in interest. What is the interest rate of the account?
5.5%
What is R?
-14= 7R+ 2R+ 8.5
R= -2.5
Credit
Ability to make a purchase before payment, based on the assumption that payment will be made in the future.
Dilation
Transformation that enlarges or reduces a figure
Point D (9,-8) is reflected to D' (9,8)
X-axis
(Tell me interest earned & Total Value)
Donna deposits $850 in an account of interest earned and the total value of the account after 60 months.
Interest Earned- $130.61
Total Value- $980.61
What is N?
17n-23n+ 11.5n= 44
N=8
Height of a prism
Pre- Image
Shape or figure before a transformation; The original figure
Ben is going to rotate a figure in Quadrant IV 90 degrees counterclockwise. What quadrant should the image be in?
Quadrant I
(Say the interest & total value)
$600 deposit for 30 years at a simple interest rate of 2%.
Interest-$360
Total Value-$960
James bought a cheeseburger, fries, and a drink for dinner. The cheeseburger was three time the price of the fries, and the drink and the fries were the same price. If the entire meal cost $12.50, what was the price of each item?
Cheeseburger- $7.50
Fries- $2.50
Drink- $2.50
Scale Factor
Ratio of corresponding sides in similar figures; the multiplier used to create a dilation.
Area of the sides (faces) of a three-dimensional object; the surface area of a three- dimensional figure excluding the bases.
Lateral Surface Area
