Which of the following is NOT a method to solve a quadratic equation?
A.quadratic formula
B.factoring
C.rationalizing the denominator
D.taking square roots
Answer: C. rationalizing the denominator
Rationalizing the denominator is a useful step to simplify expressions where there are square roots in the denominator. It doesn't apply to actually solving a quadratic. On the other hand, the quadratic formula can solve quadratics. The same applies for choices B and D as well.
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

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
I hope that explanation helped
you understand why the answer
is 288.
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]

Answer:
1.) x=61 2.) c=62
Step-by-step explanation:
Answer:
x=61 c=62
Step-by-step explanation:
1)multiply both sides by seven
56=x-5 add 5 to both sides
61=x
2) multiply both sides by -3
63=c+1 subtract one from both sides
c=62

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

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

Which equation is represented by the model? x2 – 2x – 3 = (x – 3)(x 1) x2 – 4x 3 = (x – 3)(x – 1) x2 2x 3 = (x 3)(x – 1) x2 4x – 3 = (x 3)(x 1).
The equation which can be represented by the algebraic model are provided in option A and option B as,
[tex]x^2 - 2x - 3 = (x - 3)(x +1)[/tex]
[tex]x^2 - 4x+ 3 = (x - 3)(x - 1)[/tex]
What is algebraic model?Algebraic model are the expression which consist the variables, coefficients of variables and constants.
The algebraic model are used represent the general problem in the mathematical way to solve them.
Let's check the first option,
[tex]x^2 - 2x - 3 = (x - 3)(x +1)[/tex]
Multiply the brackets to solve it further as,
[tex]x^2 - 2x - 3 = x^2+x-3x-3\\x^2 - 2x - 3 = x^2-2x-3[/tex]
As, the LHS is equal to the RHS. Thus, this is correct option.
Second option is given as,
[tex]x^2 - 4x+ 3 = (x - 3)(x - 1)[/tex]
Multiply the brackets to solve it further as,
[tex]x^2 - 4x+ 3 = x^2 -x-3x+3\\x^2 - 4x+ 3 = x^2 -4x+3[/tex]
As, the LHS is equal to the RHS. Thus, this is correct option.
Third option is given as,
[tex]x^2 +2x+ 3 = (x +3)(x - 1)[/tex]
Multiply the brackets to solve it further as,
[tex]x^2 +2x+ 3 = x^2 -x+3x - 3 \\x^2 +2x+ 3 = x^2 +2x - 3[/tex]
As, the LHS is not equal to the RHS. Thus, this is not correct option.
Forth option is given as,
[tex]x^2 +4x - 3 = (x+ 3)(x +1)[/tex]
Multiply the brackets to solve it further as,
[tex]x^2 +4x - 3 = x^2+ x+3x +3\\x^2 +4x - 3 = x^2+4x +3[/tex]
As, the LHS is not equal to the RHS. Thus, this is not correct option.
Hence, the equation which can be represented by the algebraic model are provided in option A and option B as,
[tex]x^2 - 2x - 3 = (x - 3)(x +1)[/tex]
[tex]x^2 - 4x+ 3 = (x - 3)(x - 1)[/tex]

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..
