Answer:
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection)

Step-by-step explanation:
A large koi pond is filled from a garden hose at the rate of 12 gal/min. Initially, the pond contains 200 gal of water.
(a) Find a linear function V that models the volume of water in the pond at any time t.
(b) If the pond has a capacity of 1304 gal, how long does it take to completely fill the pond?
a) The linear function that models the amount of water after t minutes is given by:
[tex]V(t) = 200 + 12t[/tex]
b) It takes 92 minutes to completely fill the pond.
Item a:
Initially, the pond contains 200 gal of water, that is, the linear function has a y-intercept of 200.Filled at a rate of 12 gallons per minute, thus the linear function has a slope of 12.Then, the function is:
[tex]V(t) = 200 + 12t[/tex]
Item b:
It takes t minutes to fill the pond, t is found for which:
[tex]V(t) = 1304[/tex]
Then
[tex]200 + 12t = 1304[/tex]
[tex]12t = 1104[/tex]
[tex]t = \frac{1104}{12}[/tex]
[tex]t = 92[/tex]
It takes 92 minutes to completely fill the pond.

Answer:
x = 6
Step-by-step explanation:
because of the exterior angle theorem, instead of looking for the inner angle's amount, I can directly look for the other angle's amount.
so:
6x + 8 + 5x + 8 = 82
11x + 16 = 82
11x = 66
x = 6

Answer:
24 cars
Step-by-step explanation:
By using 11 cars and AED 79.75, you can find out the cost of washing 1 car.
(AED 79.75)/(11 cars) = AED 7.25 / car
Now we divide AED 174 by AED 7.25/car to find the number of cars.
(AED 174) / [(AED 7.25)/car] = (174/7.25) cars = 24 cars
Answer: 24 cars

Step-by-step explanation:
you will have to replace the n with -7, that means,
(-7+5)2
when a number is beside a bracket, it automatically means multiply
you will have to solve the numbers in the bracket first
-7 +5 is equal to -2
then, -2 multiplied by 2 is equal to -4

Write the equation of a line that passes the point (-6,9)and is perpendicular to a line that passes through the points (-2,1) and (6,7).
Answer:
y = 4/3x + 1.
Step-by-step explanation:
The equation of the lines passing through (2,1) and (6,7) is:
y - 7 = (7-1)/(6- -2)(x - 6)
y - 7 = 6/8(x - 6)
y = 3/4(x - 6) + 7
y = 3/4x + 5/2.
So the line perpendicular to it has slope -1/3/4 = -4/3:
y - 9 = -4/3(x + 6)
y = -4/3 x - 8 + 9
y = 4/3x + 1.

The length of a rectangle is 4ft longer than it’s width. If the perimeter of the rectangle is 68ft, find it’s length and width.
Answer:
Represent the length and width by L and W. Then L = W + 4.
Using the perimeter formula: P = 2L + 2W = 68 ft = 2W) + 2(W+4).
Solve for W: 68 = 2W + 2W + 8, or 4W = 60. Thus, W = 15 and L = 19.
The dimensions of the rectangle are 15 by 19 feet.

Answer:
Read below
Step-by-step explanation:
For the first row, the inequality is x ≤ -5.
For the second row, the inequality is x < -5.
For the last row, the inequality matching the graph is x ≥ -5.
A trick to remember the sign is if the point on the graph is empty, then the sign would be either < or >, and if it's filled, it would be ≤ or ≥.
Also, x is less is on the left (negative) and x is more is on the right (positive).

then climbed at 0.4 meters per second for 5 seconds.
What was the average rate of change in altitude per second?
Answer:
Step-by-step explanation:
we will use 0,8 in 10 seconds as thats the easiest.
for 10 to become 1 we move the decimel once to the right, 10/10
same will happen to 0.8,
10/10=1
0.8/10=0.08

If <5 and <6 are complementary angles, and m<6=6", find m<5.
Answer:
∠ 5 = 84°
Step-by-step explanation:
Complementary angles sum to 90° , then
∠ 5 + ∠ 6 = 90° , that is
∠ 5 + 6° = 90° ( subtract 6° from both sides )
∠ 5 = 84°
