If f(x)=x^2+3 and g(x)=2x-5 find (f-g) (x)
Answer:
[tex](f - g)(x) = x^2-2x-2[/tex]
Step-by-step explanation:
We have the following two functions:
[tex]f(x)=x^2 +3g(x) = 2x-5[/tex]
In order to solve for [tex](f - g)(x)[/tex] we look at the two functions and realize that:
[tex](f - g)(x) = f(x) - g(x) = x^2+3-2x-5=x^2-2x-2[/tex]
Therefore:
[tex](f - g)(x) = x^2-2x-2[/tex]

Step-by-step explanation:
y=5(x-4) +5 -> y= 5x -20 +5 -> combine to get y=5x-15
An article was sold at a price of $360. If the profit made by the shopkeeper is 20%, find the cost price of the article
Answer:
288
step by step explanation:you first have to figure ot what
does 20% means. And this
questions is with subtracting.
So,
20% = 72
And since the question is with
subtracting we use our 360$
from before and we subtract.
360$ - 20% = 288 or
360$ - 72 = 288

The 14 compact cars sold by a dealer on Monday was 56% of the cars sold that day.
step by step please
the 14 cars sold = 56% of total car stock
how many cars (noted n) for 100 % ?
14.............56%
n..............100%
n x 56% = 14 x 100%
n = 14 : 0,56
n = 25
total cars in stock : 25
56% were sold
so 25 x 56% = 14 have been sold

c is inversely proportional to d.
c=0.5 when d=6
Find a formula for c in terms of d.
I think this is the answer!
c=3/d
The formula for c in terms of d is c= 3/d
What is Constant of proportionality?The ratio between two quantities that are directly proportional is the constant of proportionality. When two quantities grow and shrink at the same rate, they are directly proportional. When y and x are two values that are directly proportional to one another, the proportionality constant k is defined as k=y/x.
Given:
c=0.5 when d=6
We know that c is inversely proportional to d.
c ∝ 1/d
c = k / d
and, k = cd
k = 0.5 x 6
k = 3
Hence, the formula for c in terms of d is c= 3/d

Calvin kicked a soccer ball laying on the ground. It was in the air for 5 seconds before it hit the ground. While the soccer ball was in the air it reached a height of approximately 25 feet. Assuming that the soccer ball’s height (in feet) is a function of time (in seconds), what is the range in the context of this problem?
Answer:
The range is 0-25 feet
Step-by-step explanation:
Mathematically, when we are talking of the range, we are simply referring to the values at the boundaries.
This refers to the y-axis values. That is the values of the dependent variable
If we are to plot the graph, we will have the time on the x-axis while the amount of time spent in air would be on the y-axis
The base height is from the ground which is marked 0 feet to a maximum height of 25 feet
So the range in the context of this problem is 0-25 feet
The number of inches in a foot is 12. How many centimeters are in a foot? Explain the steps you used to find the answer.
Answer:

12 inch=12*2.5 cm =30 cm
Therefore, 1 foot =30 cm

What is the LCM of 600 and 1050?
Thanks :)
Answer:
4200
Step-by-step explanation:
The least common multiple (LCM) is the product of the unique factors of the numbers:
600 = 4 × 150
1050 = 7 × 150
LCM(600, 1050) = 4×150×7 = 4200
_____
The above factoring may also help you see that the LCM is also the product divided by the greatest common factor:
LCM(600, 1050) = 600 × 1050 / GCF(600, 1050)
= 600 × 1050 / 150
= 4200
Write an equation of the parabola in vertex form that passes through (13,8) and has vertex (3,2).
Answer:
[tex]y=\frac{3}{50} (x-3)^{2}+2[/tex]
Step-by-step explanation:
Vertex: (3,2)
Point: (13,8)
The equation form is [tex]y=a(x-h)^2+k[/tex]
h = 3
k = 2
y = 8
x = 13
Plug in the values into the form..
[tex]8=a(13-3)^{2} +2[/tex]
Simplify and solve for a..
[tex]8=a(10)^{2}+2[/tex]
[tex]8=100a+2[/tex]
[tex]100a=8-2[/tex]
[tex]100a=6[/tex]
[tex]a=\frac{6}{100} or \frac{3}{50}[/tex]
Plug a into the equation..
[tex]y=\frac{3}{50} (x-3)^{2}+2[/tex]
Hope this helped you!
