Solve the following quadratic equations
[tex]x { }^{2} - x - 42[/tex]
[tex]x {}^{2} + x - 6[/tex]
[tex]r {}^{2} - 25[/tex]
Answer:
see explanation
Step-by-step explanation:
To solve these equations equate them to zero, that is
x² - x - 42 = 0
Consider the factors of the constant term (- 42) which sum to give the coefficient of the x- term (- 1)
The factors are - 7 and + 6, since
- 7 × 6 = - 42 and - 7 + 6 = - 1 , thus
(x - 7)(x + 6) = 0
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 6 = 0 ⇒ x = - 6
Solutions are x = - 6, x = 7
---------------------------------------------------------
x² + x - 6 = 0 ← in standard form
(x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 2 = 0 ⇒ x = 2
Solutions are x = - 3, x = 2
------------------------------------------------------------
x² - 25 = 0 ( add 25 to both sides )
x² = 25 ( take the square root of both sides )
x = ± [tex]\sqrt{25}[/tex] = ± 5
Solutions are x = - 5, x = 5

Answer:
Chopped tomatoes
= 3/4 x 800 = 600g
Stock
= 3/4 x 600 = 450 ml
Red wine
= 3/4 x 300 = 225 ml
Answer: See below
Step-by-step explanation:
For this problem, you will need to use proportions to make sure that the ingredients are the correct amounts when the grams of minced beef is decreased.
Chopped tomatoes
[tex]\frac{400g beef}{800 g tomatoes} =\frac{300g beef}{x}[/tex] [cross multiply]
[tex]400x=240000[/tex] [divide both sides by 400]
[tex]x=600g[/tex]
We will need 600 g chopped tomatoes.
------------------------------------------------------------------------------------------
Stock
[tex]\frac{400g beef}{600ml stock} =\frac{300gbeef}{x}[/tex] [cross multiply]
[tex]400x=180000[/tex] [divide both sides by 400]
[tex]x=450[/tex]
We will need 450 ml of stock.
------------------------------------------------------------------------------------------
Red wine
[tex]\frac{400g}{300ml} =\frac{300g}{x}[/tex] [cross multiply]
[tex]400x=90000[/tex] [divide both sides by 400]
[tex]x=225[/tex]
We will need 225 ml of red wine.

What is the solution to -2(8x – 4)< 2x + 5?
Ox>
Ox<
O x > 6
O x<6
Answer:
x> 1/6
Step-by-step explanation:
-2(8x – 4)< 2x + 5
Distribute
-16x +8 < 2x+5
Add 16x to each side
-16x +8+16x < 2x+16x+5
8 < 18x+5
Subtract 5 from each side
8-5 < 18x
3 < 18x
Divide each side by 18
3/18 < 18x/18
1/6 < x
Answer:
[tex]x > \frac{1}{6} [/tex]
First answer is correct.
Step-by-step explanation:
[tex] - 2(8 x - 4) < 2x + 5 \\ - 16x + 8 < 2x + 5 \\ - 16x - 2x < - 8 + 5 \\ - 18x < - 3 \\ \frac{ - 18x}{ - 18} < \frac{ - 3}{ - 18} \\ x > \frac{1}{6} [/tex]
find the amount at compound interest that #600 would be at 3% the end of the first year, 2% at the end of the second year
Step-by-step explanation:
First we find the interest at the end of the first year.
Principal = #600
Rate = 3%
Time = 1 year
Interest = [tex]\frac{600 * 3 * 1}{100}[/tex]
= #18
Amount = #618 at the end of the first year
Now at the end of the second year.
Principal now = #618
Rate now = 2%
Time = 1 year
Interest = [tex]\frac{618 * 2 * 1}{100}[/tex]
= #12.36
Amount = #630.36 at the end of the second year

What is a Venn diagram?A Venn diagram is an overlapping circle to describe the logical relationships between two or more sets of items.
We have,
The number of students who like both algebra and geometry is the intersection of A and G, denoted as A ∩ G.
The number of students who like algebra only is the difference between A and A ∩ G, denoted as A - A ∩ G.
The number of students who like geometry only is the difference between G and A ∩ G, denoted as G - A ∩ G.
The number of students who do not like either subject is the complement of the union of A and G with respect to U, denoted as U - (A ∪ G).
We are given that:
A = 45
G = 53
U = 75
U - (A ∪ G) = 6
Now,
U - (A ∪ G) = 6
75 - (45 + 53 - A ∩ G) = 6
27 = A ∩ G
Therefore,
The number of students who like both algebra and geometry is 27.

Answer:
h = 2.5
Step-by-step explanation:
250 + 200h = 300 + 180h
subtract 180 from both sides250 + 200h - 180 = 300 + 180h - 180

The cost of endless chicken wings and sauce at resturant X is $10. The cost of chicken wings at Resturant Z is $0.50 per wings plus a one-time $1.50 charge for sauce. The total cost, c, of n chicken wings can be represented by a system of equations.
Answer:
10=.50n+1.50
Step-by-step explanation:
The total cost, c, of n chicken wings can be represented by a system of equations as follows c = 0.50n + 1.50
c = total cost
n = number of chicken wings
Therefore,
The cost of chicken wing at restaurant Z is $0.50 per wings plus a one time $1.50 charge for sauce.
The system of equation that represent the system is as follows:
c = 0.50n + 1.50
The one time fee for sauce is just like a constant in the equation.

A relação entre o tempo e a distância percorrida pelo ciclista é uma função? Justifica.
Answer: Yes, it is a function.
Step-by-step explanation:
This question is:
"A relation between time and distance traveled by a biker is a function?"
Well, as you may know, a function is a relation where each value in the domain or input, has only linked one value in the range or output.
In this relation the domain is time and the range is the distance.
Now, as you know, at each given time, the distance of the biker can be only one (he can not be at different locations at the same time) so this relation is actually a function.
How many roots do u thinn
Answer:
2 roots1 rootStep-by-step explanation:
Each equation is in vertex form, so you can easily determine the number of real roots. The leading coefficient tells you whether the parabola opens upward (positive) or downward (negative).
y = a(x -h)^2 +k
has leading coefficient "a" and vertex (h, k).
__
f(x) = 1/3(x +5)^2 +7
vertex: (-5, 7), opens downward
The vertex is above the x-axis, so there are two real roots.
__
f(x) = -5(x -3)^2
vertex: (3, 0), opens downward
The vertex is on the x-axis, so there is one real root.

A tent in the shape of a triangle prism is made using the following piece of fabric.
Find the surface area of the fabric. Explain your reasoning
Answer:
85.84 ft²
Step-by-step explanation:
The surface area of the fabric would be the total net area of the shape of the tent covered.
Thus, surface area = area of the 3 rectangular faces + area of the 2 triangular faces
From the diagram given, the 3 rectangular faces have the same dimensions as follows:
L = 6ft
W = 4ft
Area of the 3 rectangular faces = 3(6*4) = 3(24) = 72ft²
The 2 triangular faces have the same dimensions as follows:
B = 4f
H = 3.46ft
Area of the 2 triangular faces = 2(½*B*H)
= 2(½*4*3.46)
= 2(2*3.46)
= 2(6.92)
= 13.84 ft²
Surface area of fabric used to cover the triangular tent = 72ft² + 13.84ft² = 85.84 ft²
Answer:
85.84

La suma de las edades de tres personas es 127años. La mayor tiene 30 años mas que la menor y la del intermedio 26 menos que la menor.¿ calcula la edad de la persona mayor'
Answer:
La mayor tiene 61 años.
Step-by-step explanation:
Sea x,y,z la edad de la mayor, intermedio y la menor respectivamente.
Tenemos las siguientes ecuaciones:
[tex]x+y+z=127[/tex] (la suma de las edades es 127)
[tex]x = z+30[/tex] (la mayor tiene 30 años más que la menor)
La frase "y la del intermedio 26 menos que la menor" no tiene sentido, puesto que esto implicaría que la del intermedio es menor que la menor. Luego se asume que la frase ha de ser "y la del intermedio 26 menos que la mayor"
[tex]x-26 = y[/tex] (la del intermedio tiene 26 menos que la mayor).
La segunda ecuación se traduce a x-30 =z. Si reemplazamos todo en la primera ecuación obtenemos
[tex]x+(x-26)+(x-30) = 127[/tex]
Obtenemos la ecuación
[tex]3x-56 = 127[/tex]
Sumando 56 a ambos lados y dividiendo por 3, obtenemos
[tex] x = \frac{127+56}{3} = 61[/tex]
Es decir la mayor tiene 61 años.

For two rectangles to be similar polygons, it means that the ratio of their corresponding sides must be the same.
In question 1;
Ratio of corresponding left sides = 1225/3.5 = 350
Ratio of corresponding bottom sides = 144/1.2 = 120
Ratios do not correspond and as such they are not similar polygons.
In question 2;
Ratio of corresponding left sides = 13/5.2 = 2.5
Ratio of corresponding bottom sides = 5/2.5 = 2
Ratios do not correspond and as such they are not similar polygons.
In question 3;
Ratio of corresponding left sides = 18/4.5 = 4
Ratio of corresponding bottom sides = 6/1.5 = 2l4
Ratios correspond and as such they are similar polygons.
In question 4;
Ratio of corresponding left sides = 40/8 = 5
Ratio of corresponding bottom sides = 15/3 = 5
Ratios correspond and as such they are similar polygons.
