#1: if there is buy 1 get 1 free, then buy 6 get 3 free. so 2.8 times 3 = $8.4
#2: 4 for $3. break it up to 1 for $0.75. now 0.75 times 6 = $4.5
#3: the second one. $4.5 < $8.4
#4: 45 times 12 = $54
Write the equation of the line that passes through (-3,9) and is parallel to y = -2x + 5
Answer:
y = -2x +3
Step-by-step explanation:
Parallel lines always have the same slope
To insert the point, use the slope intercept formula: y =mx+b
insert y (9)
insert x (-3)
insert the slope -2
9 = (-2)(-3) + b
9 = 6+b
subtract 6 from both sides
3 = b

transformation?
Ro, 90°
Ro, 180°
Ro, 270°
Ro, 360°
Answer:
Ro, 360°
Step-by-step explanation:
Given
(x,y) transformed to (x,y)
Required
Determine the transformation
We have the following observations
Before transformation, the coordinates are: (x,y)
After transformation, the coordinates are: (x,y)
In other words, the coordinates before and after the transformation are the same.
This implies that there is a 360 degrees rotation.
Simply put, when there are no changes in the pre and post transformation of a point, line or shape, then the transformation is 360 degrees
The parallelogram transformed according to the rule (x,y) → (x, y), in other words can be stated as 360 degrees rotation (Ro, 360°).
360 degrees rotation
For 360 degrees rotation, the coordinates before and after the transformation will be the same.
According to this rule, the transformation of (x,y) gives (x, y)
Thus, the parallelogram transformed according to the rule (x,y) → (x, y), in other words can be stated as 360 degrees rotation (Ro, 360°).

Li bought his dog Spot a huge bone that is 15 inches long. Spot chews 4 inches off the bone every day. What is the new length of the bone after 3 days?
Answer:
3 inches
Step-by-step explanation:
If the dog chews off 4 inches every day, you first have to multiply the inches by the number of days, which in this case is 3 x 4, which equals 12. In 3 days, he chewed off 12 of the original 15 inches, leaving only 3 inches left.

Answer: line a
Step-by-step explanation:
line a becuse the walking is going strigt ahead and it quicker too
I don't know how doing this
Slope intercept form - y = m(x) + b. m represents slope, b represents the y-intercept. You should be able to plug in any value for y and x into the equation, and it should result in a true statement.
The y-intercept is easy to find. It is the point where X is equal to zero and the graph line crosses through the y axis. In this case, y intersects at -2. Since we insert the y intercept at b, we can go ahead and plug it in there.
y = m(x) + b > y = m(x) - 2
Since there is only one option with the y intercept equalling -2, you can go ahead and pick D) y = -x - 2 as your answer, since no other options have the correct y-intercept.

In the given figure, ABCD is a trapezium in which AD || BC,
ABC = 90°, AD = 16 cm, AC = 41 cm and BC = 40 cm. Find the
area of the trapezium,
Answer:
252 cm²
Step-by-step explanation:
Find AB:
AB² = 41² - 40²
AB² = 81
AB = √81
AB = 9 cm
Area of the trapezium = ½(a + b) × h
Where,
a = 16 cm
b = 40 cm
h = 9 cm
Area = ½(16 + 40) × 9
Area = ½(56)×9
Area = 252 cm²
