When you multiply a function by -1, what is the effect on its graph?
A. The graph flips over the line y=x
B. The graph flips over the x-axis
C. The graph flips over the y-axis

Answer:
B. The graph flips over the x-axis
Step-by-step explanation:
When you plot the coordinate pair (x, y), you plot the point 'y' units above the x-axis. If you change the sign of that (multiply the function by -1), then the point becomes (x, -y), and is plotted 'y' units below the x-axis.
The graph flips over the x-axis.

Attached is an example of a function with its original graph (red) and the graph after being multiplied by -1 (blue). The blue graph is a reflection of the red graph across the x-axis.

Answer:
yes
Step-by-step explanation:
The width of the rectangle is given by ...
W = A/L
W = (20 cm²)/(8 cm) = 2.5 cm
__
The modified rectangle has a length of (8 cm +2 cm) = 10 cm, and an area of (20 cm² +4 cm²) = 24 cm². Its width will be ...
W = (24 cm²)/(10 cm) = 2.4 cm
The percentage change in size is ...
((2.4 cm)/(2.5 cm) -1) × 100% = -4%
The width of the rectangle decreased less than 5%. Noah is correct.

To find these out you have to use the strategy of P (parenthesis) E (exponents) M (multiplication) D (division) A (addition) S (subtraction)
3 - 4 x 2 The first thing you need to do is do the multiplication part first, since subtraction is the last thing you need to do. You multiply 4 and 2 and get the answer of 8, then subtract 3 which is 5
5 x 3 - 4 The first thing you need to do is multiplication 5 x 3 which equals 15 and then do 15 - 4 = 11
15 ÷ (3 x 5) x 2 The first thing you do is you do the P (parenthesis) which is (3x5) which equals 15. Then you multiply 15 with 2 which is 30 and then divide 30 with 15 which is 2
5 + 3 x 2 ÷ 6 First you need to do the Multiplication which is 3 x 2 which equals 6, and then you do the division, which is 6 ÷ 6 which is 1. Then add 5 to the 1 which is 6.

Step-by-step explanation: 20% of 85 is the same thing as 85 times 0.2. that equals to 17. She got 17 wrong, so 85-17 equals to 68. She got 68 problems correct and 17 wrong.
The answer to this question is 68.

2. A tree casts a shadow 25m long. At the same time, a signpost next
to the tree casts a shadow 6m long. The signpost is 3.5m tall. How
tall is the tree?
(10 pts.)
Answers
Answer:
The height of the tree is 14.85[tex]\bar 3[/tex] m
Step-by-step explanation:
The length of the shadow cast by the tree = 25 m
The length of the shadow cast by the signpost = 6 m
The height of the signpost = 3.5 m
Therefore, by similar triangles, we have;
Let θ, represent the angle formed by the line extending a line from the tip of the shadow, to the tip of the object and let x represent the height of the tree, we have
Tan(θ) = Opposite/Adjacent = Height of the object/(The length of the shadow)
∴ Tan(θ) = 3.5/6 = x/25
x = 25 × 3.5/6 = 14.58[tex]\bar 3[/tex]
The height of the tree = x = 14.85[tex]\bar 3[/tex] m

The rule of thumb in filmmaking is that you must shoot at least 3 minutes of film for every minute in a movies “final cut”. A 30 minute roll of film cost $250. How much will film cost to make a 90 minute movie?
I can't figure out the process of solving it!!!
P.S: It needs to be set up as an inequality
PLS HELPP
Answers
Answer: $750
Step-by-step explanation:
We can solve this using direct proportion.
Let the number of minutes used be x
Let the cost be y
For direct proportion,y = kx
where, y = 250, x = 30
y = kx
250 = 30k
k = 250/30
k = 8.33
The cost to make a 90 minute movie will be:
y = kx
where,
y = unknown
k = 8.33
x = 90
y = 90 × 8.33
y = $750
The cost to make a 90 minute movie is $750.
