Select ALL expressions that are equivalent to -6. *
-7 + 13
-10 - (-4)
26 - 32
16 - 10
3 - ( - 3)
Answer:
The terms equivalent to - 6 are
- 10 - ( - 4)
26 - 32
Answer:
Only the 2nd and 3rd expressions are equal to -6
Step-by-step explanation:
The only way to do this is evaluating ot actually doing each expression:
Some key skills needed are subtraction with negative numbers, distributing the negative properly, and addition.
The first one is -7+13. This can be rewritten as 13-7. And this is 6, so it is not equal to -6. The 2nd one is -10-(-4). You have to distribute that minus sign after the -10 to the -4. Think of the subtraction symbol I mentioned as -1. -1(-4) is 4 since the negative signs cancel out. It would then be -10 + 4 which -6. So this works. This one is 26 - 32. You have to subtraction here. 26 - 32 is the opposite of 32 - 26. 32 - 26 is 6, so 26 - 32 would be -6. So the 3rd one is another one eqial to -6. This is simple subtraction. 16 - 10 is 6, so this one definitely does not work. This uses the same skill as number 2. Think of the minus sign after the positive 3 as a -1. -1(-3) is 3, so it would be 3 + 3 which is 6.Only the 2nd and 3rd ones work. Hope you understood and have a nice day!!

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 6 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 6) would represent a height of 6 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)
Part C: If the rate at which the candle burnt was 0.3 inches per hour instead of 0.5 inches per hour, will the relation continue to be a function? Explain your answer using input and output values. (3 points)
Answer:
Part A: 0,6 1, 5.5 2,5.0 3,4.5 4,4.0 5,3.5 6,3.0
Step-by-step explanation:
Part B: This would be a function, it has a constant rate of change.
Part C: 0,6 1,5.7 2,5.4 3,5.1 4,4.8 5,4.5 6,4.2, this would still be a function, just at a slower rate of speed.

What are the coordinates of the point (-9, 4) after a 90 degree rotation followed by a translation 3 units right?
The coordinates of the point (-9, 4) after a 90 degree rotation followed by a translation 3 units right are (8,9) (for clockwise rotation) and (0,-9) (for counterclockwise rotation)
How does rotation by 90 degrees changes coordinates of a point if rotation is with respect to origin?Let the point be having coordinates (x,y).
Case 1: If the point is in first quadrant:Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
Case 2: If the point is in second quadrant:Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
Case 3: If the point is in third quadrant:Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
Case 4: If the point is in fourth quadrant:Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
Case 5: For points on axesYou can take that point in any of the two surrounding quadrants. Example, if the point is on positive x axis, then it can taken as of first quadrant or fourth quadrant.
Case 6: On originNo effect as we assumed rotation is being with respect to origin.
For this case, the point (-9,4) (present in second quadrant) is rotated by 90 degrees.
This rotation can be either clockwise, or counterclockwise.
Thus, for each case, we have:
case 1: Clockwise rotation:Then (x,y) → (y, -x), therefore, (-9,4) → (4, 9)
case 2: Counterclockwise rotation:Then (x,y) → (-y, x), therefore, (-9,4) → (-4, -9)
Now, when shifting to right by 4, that means, we're making no changes vertically, but old x-coordinates are increased by 4 to make them shift to right side as value of x increases as we go more and more to the right side with respect to the origin and in defaultly oriented cartesian space.
Thus, we have:
case 1: Clockwise rotation:
After translation of 4 units right:
(4, 9) → (4+4, 9) = (8,9)
case 2: Counterclockwise rotation:After translation of 4 units right:
(-4, -9) → (-4+4, -9) = (0,-9)
Thus, the coordinates of the point (-9, 4) after a 90 degree rotation followed by a translation 3 units right are (8,9) (for clockwise rotation) and (0,-9) (for counterclockwise rotation)

Associative property of addition, you can add 3 or more different numbers any which way, the sum will be the same.
Commutative Property of Addition - same as the associative property but with 2 numbers.
Identity Property of Multiplication - Any number multiplied by one is itself
Multiplicative Property of Zero: x * 0 = 0
Associative Property of Multiplication - Same as that of addition, yet with multiplication.
Distributive Property: Factoring Out.
EX: (12 x 15) = 3(4 x 5)
