Answer:
21x+7
The value of (fog)(x) is, 21x+7
Step-by-step explanation:
Given the functions:
f(x) = 7x
g(x) = 3x+1
We have to find (fog)(x)
(fog)(x) = f(g(x))
substitute the function g(x) we have;
(fog)(x) = f(3x+1)
Replace the value of x from 3x+1 in f(x) we have;
(fog)(x) =7(3x+1)
⇒(fog)(x) = 21x+7
Therefore, the value of (fog)(x) is, 21x+7

On the coordinate plane shown, each grid unit represents 10 feet. Polygon QRST has vertices Q(20, 10), R(−20, 10), S(−20, −20), and T(20, −20), and represents the floor plan of a room. Find the perimeter and area of the room.
Answer:
P 140 units
A 1200 units^2
Step-by-step explanation:
The length of the rectangle is 20 to -20 = 20 - -20 = 40 units
The width of the rectangle is 20 to -10 = 20 - -10 = 30 units
The perimeter is given by
P = 2 ( l+w) = 2 (40+30) = 2 (70) = 140 units
The area is given by
A = lw = 40*30 = 1200 units^2

Answer:
3^5 = 243 square feet
Step-by-step explanation:
Ellen’s dog has a pen that is 3² feet by 3³ feet. To find its area we follow the next steps:
1. Multiply powers:
A = 3² * 3³
2. Expand each power:
A = (3*3) * (3*3*3)
3. Simplify:
[tex]A = 3^5[/tex]

Circle G:(x-14)^2+(y+12)^2=49 and Circle H:(x-18)^2+(y-8)^2=196. Describe a complete series of transformation from Circle G to Circle H.
Step-by-step explanation:
The equation
(x - a)² + (y - b)² = r²
describes a circle of radius r, with center at the point (a, b).
G is a circle of radius 7 units, centered at the point (14, -12).
H is a circle if radius 14 units, centered at the point (18, 8).
Answer:
Dilation
Step-by-step explanation:
The general form of a circle with center at (h, k) and radius r units is given as
(x - h)² + (y - k)² = r²
G is a circle centered at the point (14, -12) with radius 7 units.
G is dilated 4 units to the right on the x-axis, 20 units upwards on the y-axis, and 7 units on the radius to a circle H with center at the point (18, 8) and radius 14 units.

What is the equation of a horizontal line passing through the point (-3, 8)?
Ox=-3
Oy=8
Ox= 5
Oy=-11
Answer:
Y=8
Step-by-step explanation:
A horizontal line is going to be parallel to the x-axis, so you need to use your y-value to determine the equation of the line. Your y-value in the coordinate (-3,8) is 8, so y=8
Answer: y = 8
Step-by-step explanation: Whenever we are given a line and the problem says that it's horizontal or a flat line, we know that the equation of the line will always be in the form "y = a number".
Since we are given that the y-coordinate is 8, that means that
the equation of this line will be y = 8.

Answer:
D. y = -2x + 20
Step-by-step explanation:
first, plot these points on a linear graph.
work down from the top:
A. y = 2x + 5
look at the last number first, this means the line will cross over the y axis (vertical line) at + 5. draw a point on + 5
y = 2x + 5
From this point (+5), the 2x means that for every 1 square you move across (to the right), you will go up 2. This will make the second point of the line. connect the dots. (see picture 1 below)
B. y = 2x - 6
the last number means the first point will be on -6 on the y axis.
y = 2x - 6
the 2x means that every 1 square you go across (to the right) from that point, you will move up 2
C. y = 2x
as there is no second number, this line will cross through the center of the graph. the 2 means that for every 1 square you move across from that point, you will move up 2
D. y = -2x + 20
the +20 means this line will cross the y axis and + 20, the -2 means that for every 1 square you move across to the right, you move DOWN 2.
this is the only line that moves down from left to right
f(1) = 1
f(2) = 2
f(n) = f(n − 2) + f(n - 1)
f(3) =?
Answer:
3
Step-by-step explanation:
To find f(3) we just need to plug in 3 wherever we see an n
f(3) = f(3 - 2) + f(3 - 1)
f(3) = f(1) + f(2)
Since f(1) and f(2) are given, we can plug in the respective values
