A system has an infinite number of solutions. one equation is 3x-3y=8. Which could be the other equation in the system of equations?
Answer:
[tex]6x-6y-16=0[/tex]
Step-by-step explanation:
Consider the following system of equations:
[tex]a_1x+b_1y+c_1=0\\\\a_2x+b_2y+c_2=0[/tex]
The system of equations has infinite solutions if [tex]\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}[/tex]
One equation is [tex]3x-3y=8[/tex]
[tex]3x-3y-8=0[/tex]
Take another equation as [tex]6x-6y-16=0[/tex]
So, the two equations are [tex]3x-3y-8=0[/tex] and [tex]6x-6y-16=0[/tex]
[tex]a_1=3,b_1=-3,c_1=-8,a_2=6,b_2=-6,c_2=-16[/tex]
[tex]\frac{a_1}{a_2}=\frac{3}{6}=\frac{1}{2}\\ \frac{b_1}{b_2}=\frac{-3}{-6}=\frac{1}{2}\\ \frac{c_1}{c_2}=\frac{-8}{-16}=\frac{1}{2}[/tex]
So,
[tex]\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}[/tex]
Therefore, another equation can be [tex]6x-6y-16=0[/tex]
the equation of a circle is x2 + y2 - 12x + 6y + 20 = 0.

Horace measured a circular lid and found d, the diameter, was 8 inches and C, the circumference, was 25 inches.
Answer:
A/C ≅ 2
Step-by-step explanation:
diameter of circle d = 8 in
Circumference of the circle C= 25 in
Let us assume we have to find the area of the circular lid A = [tex]\frac{\pi}{4}d^2[/tex]
⇒ A= [tex]\frac{\pi}{4}\times8^2= 50.24 in^2[/tex]
Therefore ratio of area to circumference A/C = 50.24/25 = 2.0096≅2

Explanation:
For proofs of this nature, it often works well to replace everything possible with appropriate equivalents. Here, we'll use sin² to represent sin²(A), and equivalent notation for other trig functions.
We will change the left side to the form of the right side.
[tex]\displaystyle \frac{\tan^2-\cot^2}{1+\cot^2}=\frac{\sin^2-\cos^2}{\cos^2}\\\\=\frac{(\sec^2-1)-(\csc^2-1)}{\csc^2}\\\\=(\sin^2)(\sec^2-\csc^2)\\\\=\frac{\sin^2}{\cos^2}-1=\frac{\sin^2-\cos^2}{\cos^2}\qquad\text{Q.E.D.}[/tex]
__
The equivalents (identities) used are ...
1+tan² = sec²
1+cot² = csc²
1/csc = sin
sec = 1/cos
El reloj de Nuestra Basílica de Chiquinquirá señala cada hora con igual número de campanadas. Para indicar las 6 a.M. Tocó 6 veces la campana y demoró 15 segundos. ¿Cuántos segundos empleará para indicar las 8 a.M.?
Answer:
El reloj de Nuestra Basílica de Chiquinquirá empleará 20 segundos para indicar las 8 a.m.
Step-by-step explanation:
De acuerdo a la información proporcionada, sabes que el reloj de Nuestra Basílica de Chiquinquirá señala cada hora con igual número de campanadas, por lo que a las 8 a.m. tocará 8 campanadas y puedes usar una regla de tres para encontrar cuantos segundos empleará en hacerlo dado que conoces que las 6 campanadas se demoran 15 segundos:
6 campanadas → 15 segundos
8 campanadas → x
x=(8*15)/6
x= 20
De acuerdo a esto, la respuesta es que el reloj de Nuestra Basílica de Chiquinquirá empleará 20 segundos para indicar las 8 a.m.

Step-by-step explanation:
Brooklyn needs to order some new supplies for the restaurant where she works. The
restaurant needs at least 498 glasses. There are currently 230 glasses. If each set on
sale contains 10 glasses, write and solve an inequality which can be used to determine
x, the number of sets of glasses Brooklyn could buy for the restaurant to have enough
glasses.
Answer:
Inequality to determine number of glass sets: 10x + 230 ≥ 498
Solved inequality: x ≥ 26.8 (She needs to buy at least 27 sets)
Step-by-step explanation:
In order to write an inequality to represent this situation, you must first identify the important information:
- The restaurant needs 498 glasses total at the least
- They already have 230 glasses
- Each set of glasses has 10 glasses
Now, you can write an inequality to represent this situation:
498 (needed glasses) ≤ 230 (glasses already owned) + 10x (number of glasses in one set (x))
You can rewrite it as 10x + 230 ≥ 498 so that x is on the left and it is ordered by variable exponential value. Now you have the inequality to represent the situation, so to find the number of sets of glasses Brooklyn could buy, you need to isolate x:
10x + 230 ≥ 498 (given)
10x ≥ 268 (subtract 230 from both sides)
x ≥ 26.8 (divide both sides by 10)
So, Brooklyn needs to buy at least 27 sets since she can't buy 4/5 of a set.
Answer:
10x + 230 ≥ 498

Answer:
[tex]x=49.16^{\circ}[/tex]
Step-by-step explanation:
We need to find the value of x in the given figure.
It is a right angled triangle, in which base is 19, height is 22.
We can use trigonometry to find x.
We know that,
[tex]\tan\theta=\dfrac{P}{B}[/tex]
Where
P is perpendicular and B is base
So,
[tex]\tan x=\dfrac{22}{19}\\\\x=\tan^{-1}(1.157)\\\\x=49.16^{\circ}[/tex]
So, the value of x is equal to [tex]49.16^{\circ}[/tex].
The function f(x) = –3x2 + 36x – 119 written in vertex form is f(x) = –3(x – 6)2 – 11. Which statements are true about the graph of f(x)? Select three options.
The axis of symmetry is the line x = 6.
The vertex of the graph is at (–6, –11).
The parabola has a minimum.
The parabola opens down.
The value of h, when the equation is written in vertex form, is positive.
Answer:
A D and E
Step-by-step explanation:
The statements true about the graph of the function are
a) The axis of symmetry is the line x = 6
b) The parabola opens down
c) The vertex of the graph is at (-6, -11)
What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) = -3x² + 36x - 119
And , the vertex form of the function is
f ( x ) = -3 ( x - 6 )² - 11
Now , The axis of symmetry is the line x = 6. This is true because in vertex form, the equation of the axis of symmetry is given by x = h, where (h, k) is the vertex of the parabola. In this case, the vertex is (6, -11), so the axis of symmetry is x = 6.
The parabola has a minimum. This is also true because the coefficient of the x² term in the given equation is negative (-3), which means the parabola opens downward and has a minimum at the vertex.
Hence , the graph of the polynomial is solved

Answer: approximately 15
Step-by-step explanation:
Answer:
radius = 5.48ft

The formula for the circumference of a circle is: C = πr² or pie times the radius squared.
Now that we know this, we can plug in the equation.
94.25 = πr²
÷π ÷π
30 = r²
√30 = √r²
5.48 = r

Find the measure of ∠C. b=110 d=30 m∠C= °
Answer:

Step-by-step explanation:
If your are reffering to a triangle the answer would be 40 since the three angles of a triangle must always add up to 180° so you would add b+d (110+30) resulting in 140 which you would then subtract from 180 getting you 40°

A fmaily wants to rent a van for a four day camping trip. The rental cost is $32.00 per day plu s$0.15 per miles driven. Their vacation budget allows them to spend $225.00 to rent the van. Which expression represents the number of miles that they can drive without going over their budget?
Answer:
The expression is: (225 - (32 × 4))/0.15
Steps:
first we'll calculate the rental cost of 4 days without the miles driven
32 × 4 = $128.00
now we'll calculate the money that can be spent on miles
225 - 128 = $97.00
with $97.00 they can drive: 646.66 miles
97 / 0.15 = 646.66 miles
The expression is: (225 - (32 × 4))/0.15
