Answer:
2(5x+9) = 10x+18
3(4x+2) = 12x+6
5(3x+7) = 15x+35
Does this anwser your question?!?
Answer:
See below
Step-by-step explanation:
For there to be infinitely many solutions, the equations have to be the same on the left side of the equation as on the right
3x+6 = 3 ( x+2)
As you can see when we distribute
3x+6 = 3x+6
Another example
2x+3 = x+ x+ 1+2
When we combine like terms
2x+3 = 2x+3
A third example
2x -5 +2x -6 = 7x-3x - 15+4
Combine like terms
4x -11 = 4x -11
The model represents an equation. What value of x makes the equation true?
Answer:
x=3
Step-by-step explanation:
Okay so there are 5 small blocks! We need to get 11,but how? 5 + 6 equals eleven can we split 6 into 2? Yes we can. 6 divided by 2 equals 3 therefore our answer is the X represents 3, each tall shape is equivalent to 3 small shapes!
Write a quadratic function in standard form with zeros 1 and -10 plzzzz helppp meee
Answer:
[tex]f(x)=x^2+9x-10[/tex]
Step-by-step explanation:
Standard Form of Quadratic Function
The standard representation of a quadratic function is:
[tex]f(x)=ax^2+bx+c[/tex]
where a,b, and c are constants.
The factored form of a quadratic equation is:
[tex]f(x)=a(x-\alpha)(x-\beta)[/tex]
Where [tex]\alpha[/tex] and [tex]\beta[/tex] are the roots or zeros of f.
The question gives the zeros of the function: 1 and -10. This makes our function look like:
[tex]f(x)=a(x-1)[x-(-10)][/tex]
[tex]f(x)=a(x-1)(x+10)[/tex]
Operating:
[tex]f(x)=a(x^2+10x-x-10)[/tex]
Joining like terms:
[tex]f(x)=a(x^2+9x-10)[/tex]
Since we are not given any more conditions, we choose the value of a=1, thus. the required function is:
[tex]\boxed{f(x)=x^2+9x-10}[/tex]
The school's newspaper has asked you to contact 100 of the approximately 1100 students at the school to gather information about student opinions regarding food at your school's cafeteria. (c) You decide to conduct a survey about the quality of food served in the school cafeteria by randomly selecting students as they leave the cafeteria after lunch on a specific day next week. Describe a source of bias that may result from using this method. Be sure to use the correct terminology, and indicate the direction of the potential bias.
Answer:
Sampling bias
Step-by-step explanation:
Sampling bias is due to the mistaken manner of selection of the respondents for the survey when conducting market research or similar survey. The sampling bias error is said to have occurred when the sample selection procedure, methodology, or process focuses on part of the population with a particular attribute, rather than being a random sample. Such that a given subset of the of the population are selected for the survey, which results in a biased sample.
The length of a rectangle is 4 m shorter than its width. If the perimeter of the rectangle is 18 m, find its length and width.
Group of answer choices
2(x - 4) + 2x = 18, where x represents the width.
2x - 8 + 2x = 18 (Distribute 2)
4x - 8 = 18 (Add like terms)
4x = 26 (Add 8 to both sides)
x = 6.5 (Divide 4 from both sides)
Length = x - 4 (Length is 4 less m than Width [x - 4])
6.5 - 4 = 2.5 (Substitue in x)
Length = 2.5
The length is 2.5 meters and the width is 6.5 meters.
You can check by adding 2.5 + 2.5 + 6.5 + 6.5 = 18.
Which of these are irrational and which are rational ?
Answer:
-51/5 and √64 are rational, the rest are irrational
Step-by-step explanation:
Irrational numbers are numbers that never end; 9.68, line of the 8 means the number would be 9.6888888888... going on forever, meaning its irrational. 2.010010001... goes on forever, and the square root of 6 also goes on forever.
-51/5, however, does not go on forever. The square root of 64 is 8, so these two are rational.

Evaluate when a = 15:
2(a - 5) + 2
Answer:
22
Step-by-step explanation:
Just plug in
2(15 - 5) + 2 (Solve what's in the parenthesis)
2(10) + 2 (multiply 2*10)
20 + 2 (collect like terms)
22
The evaluation of the expression, 2(a - 5) + 2 when a = 15 is; 22
According to the question;
We are required to evaluate 2(a - 5) + 2. when a = 15.To evaluate 2(a - 5) + 2. when a = 15.
We have;
= 2(15 - 5) + 2= 2(10) + 2= 22.Read more;

Answer:
D. y = { -x + 2 x ≥ 1}
{ x + 1 x < 1}
Step-by-step explanation:
First is to eliminate A and C, why?
This is because of the end points shown on the graph.
As shown, if you look at the point of (2,1) it is black, this means that not only is it closed but it is also means ≤ or ≥ symbol.
You are now left with B and D
The difference between these two is the symbols; they are facing the opposite directions.
While B says x ≤ 1, and x > 1
While D says x ≥ 1, and x < 1
The direction of the symbols depends on the direction of the lines and what is part of it (some what like a shaded area)
So you answer would be D
