Combining like termsStep-by-step explanation:
Step 1: Define
f(x) = 4x - 8
g(x) = x - 2
(f - g)(x) is f(x) - g(x)
Step 2: Find
Substitute: (f - g)(x) = 4x - 8 - (x - 2)Distribute negative: (f - g)(x) = 4x - 8 - x + 2Combine like terms: (f - g)(x) = 3x - 6J. D. Is saving up to buy a set of Apple Airpods.

A drive in movie charges $9 per car plus $2 per person in the car. The total cost for going to the drive in movie when you go on x people are in the car is f(x) = 2x + 9. How will the graph of this function change if the cost per car is changed to $6 ?
Step-by-step explanation:
f(x)= 2x + 9
Cost per car
Change 9 to 6.
f(x) = 2x + 6
Because 9 was the y-intercept and it was changed to 6, or 3 units down, the function would be be translated 3 units down

Find the radius of a circle whose sector area is 59 square inches and whose arc measures 40o.
A line that contains the point (0,4) if the slope of the line is m=5 write the equation of the line using slope intercept form
Answer:
y = 5x + 4
Step-by-step explanation:
Slope intercept form is y = mx + b. m is the slope which is already given to you, which leaves you with y = 5x + b. Then you plug in (0,4) to find what b is. 4 = 5(0) + b
4 = 0 + b
4 = b
y = 5x + 4

Answer:
45° and 135°
Step-by-step explanation:
(a)
The sum of the angles around O = 360°
There are 8 segments from each vertex to O , thus
∠ AOB = 360° ÷ 8 = 45°
The sum of the interior angles of a regular polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 8 , then
sum = 180° × 6 = 1080°
In a regular polygon the 8 interior angles are equal, thus
∠ ABC = 1080 ÷ 8 = 135°
9514 1404 393
Answer:
a) angle AOB = 45°
b) angle ABC = 135°
Step-by-step explanation:
a) The sum of the 8 identical central angles is 360°, so each one has a measure of ...
angle AOB = 360°/8 = 45°
__
b) The sum of the 8 exterior angles is 360°, so each one is 45°, the same measure as the central angle. The measure of angle ABC is the supplement of the exterior angle at B, so is ...
angle ABC = 180° -45° = 135°
_____
In the attached image, the central point is your O. Angle AOB is the interior angle of triangle AOB whose vertex is at O.

The graph of the cube root of X is shifted one unit down in seven units to the left. What is the equation of the resulting graph? Explain
Using translation concepts, it is found that the equation of the resulting graph is given by:
[tex]y = \sqrt[3]{x + 7} - 1[/tex]
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The cube root function is given by:
[tex]y = \sqrt[3]{x}[/tex]
The changes are as follows:
Shifted one unit down, hence 1 is subtracted from the function.Shifted seven units to the left, hence [tex]x \rightarrow x + 7[/tex] in the domain of the function.Hence, the equation is given by:
[tex]y = \sqrt[3]{x + 7} - 1[/tex]

A video game system and several games are sold for $652. The cost of the games is 3 times as much as the cost of the system. Find the cost of the system and the cost of the games.
Cost of the video game system: $
Answer:
The cost of the system is $163 and The cost of the games is $489
Step-by-step explanation:
∵ A video game system and several games are sold for $652
∵ The cost of the games is 3 times as much as the cost of the system
→ Assume that the cost of the system is $x
∵ The cost of the system = x
∴ The cost of the games = 3 × x = 3x
∵ The total cost of the system and the games = 652
→ Equate the sum of the cost of the system and the cost of the games
by 652
∴ x + 3x = 652
→ Add the like terms in the left side
∴ 4x = 652
→ Divide both sides by 4 to find x
∵ [tex]\frac{4x}{4}=\frac{652}{4}[/tex]
∴ x = 163
∵ The cost of the system = x
∴ The cost of the system is $163
∵ The cost of the games = 3x
∴ The cost of the games = 3(163) = 489
∴ The cost of the games is $489

A pizza restaurant sells containers of juice that it marks up 75 percent above its wholesale cost. If the restaurant marks up each container by $0.90, how much does the restaurant pay for each container of juice wholesale?
$0.51
$0.83
$1.20
$1.58
Answer:
$1.20
Step-by-step explanation:
$0.90=75%. divide it by 3. =$0.30. do 4 times $0.30. $1.20.
Answer:
75% of what is 0.90
0.75x = 0.90
x = 0.90/0.75
x = 1.20 <== restaurant pays $ 1.20 wholesale

P = 2(w + h)
W = 12 correct to the nearest whole number
h = 4 correct to the nearest whole number
Work out the upper bound for the value P
(urgent please)
Answer:
p=32
Step-by-step explanation:
4+12=16
16×2=32
p=32
After substituting W = 12, h = 4, in the equation P = 2(w + h), P = 32
What is upper bound?"An element greater than or equal to all the elements in a given set."
What is equation?"It is an expression which contains an equal symbol."
For given question,
Given equation: P = 2(w + h)
W = 12, h = 4
After substituting these values in given equation,
⇒ P = 2 × (12 + 4)
⇒ P = 2 × 16
⇒ P = 32

Answer:
x=35, y=18
Step-by-step explanation:
