Twice the opposite of eleven will be 2(-11).
What is an expression?An expression is a combination of some mathematical symbol such that arithmetic operator and variable such that all are constrained and create an equation.
In other meaning, expression is very useful to determine the end or root value of constraint.
For example 3x +5y
The constraint of expression is represented as = or <, >.
Opposite of eleven = negative of eleven
Opposite of eleven = -11
Twice = multiply by two
So,
Twice the opposite of eleven = 2(-11) = -22
Hence "Twice the opposite of eleven will be 2(-11)".

Transitive property: if 3x plus y equals 7 and 7 equals 5x minus 2y then
Answers
7 = 5x - 2y
THEN 3x + y = 5x - 2y ... it's like you're taking out the middle man "7"
Transitive property states that if x = y and y = z then x = z.
3x + y = 7 and 7 = 5x - 2y
Using the transitive property we get,
3x + y = 5x - 2y.
What is transitive property?It states that if x, y and z are the three quantities, and if x is related to y by a rule, and y is related to z by the same rule, then we can say x is related to z by the same rule.
Example:
x + 1 = 2 and 2 = x + 9 then x + 1 = x + 9
We have,
3x + y = 7 and 7 = 5x - 2y
Using transitive property we can say that,
3x + y = 5x - 2y
Thus using the transitive property we have,
3x + y = 5x - 2y.

10y + 5x = - 5.....B
You should see right away that -10y and 10y cancel out.
We are left with
14x = -14
x = -14/14
x = -1
Plug x = -1 into EITHER equation A or B to find y.
I will use equation A.
-10y + 9(-1) = - 9
-10y - 9 = - 9
-10y = - 9 + 9

What is the side length b in the triangle below
Answers
144 + b^2 =400
B^2 =256
B=16
Answer:
Option B : 16
Step-by-step explanation:
Refer the attached file
Given :
In ΔABC , AB = b , BC = 12 , AC= 20
To Find : value of b i.e. Length of AB
Solution:
Since we are given a right angles triangle so we can use Pythagoras theorem i.e.
[tex](Hypotenuse)^{2} =(Perpendicular)^{2} +(Base)^{2} [/tex] ---(a)
Now in a given triangle AB is Perpendicular , BC is Base and AC is Hypotenuse.
So, putting values in (a)
[tex](AC)^{2} =(AB)^{2} +(BC)^{2} [/tex]
[tex](20)^{2} =(b)^{2} +(12)^{2} [/tex]
[tex]400 =(AB)^{2} +144 [/tex]
[tex]400-144 =(b)^{2} [/tex]
[tex]256 =(b)^{2} [/tex]
[tex]\sqrt{256} =b[/tex]
[tex]16=b[/tex]
Thus the value of b is 6
Hence Option B is correct.

Write each interval as an inequality. Then graph the solutions

please help, thank you so much.
Answers
notice the brackets, as opposed to parentheses.
the brackets mean, -4 is a bound and it is included in the range, and 5 is the other bound and 5 is also included in the range too.
so, whatever number "x" is, we know that is between -4 and 5, so it could be -3, -2, 1, 4 or such.
keeping in mind that, for the negative side of the numbers, the closer to 0, the greater the number, therefore, -4 is greater than -5 and is also greater than -1,000,000, because -4 is closer to 0 than those two.
so, "x" is greater than -4, and includes it, but is also less than 5, but it can be 5 too.

Mayumi is constructing a line through point P that is perpendicular to RS←→. A horizontal line segment R S and a point P are drawn. The point P is above the horizontal line segment R S. She places her compass on point P to construct an arc. What must be true about the width of the compass opening when Mayumi draws the arc? It must be greater than 12RS. It must be equal to PS . It must be wide enough so that the arc intersects RS←→ in two points. It must be equal to PR .

Width of the compass should be more than the smallest space between P and RS, so that it cuts RS at two distinct points. Therefore, it must be wide enough so that the arc intersects RS←→ in two points. The photo is attached so that you can understand it more.

Ali,s dod weighs 8 times as many as her cat.Together, the two pets weigh 54 pounds.HOW much does Ali's dog weigh
Answers
cat = 1 unit
total = 9 units
9u= 54
1u=6
8u= 48 pounds
First you have to look at the facts about what we know:
- her dog is 8 times as much as her cat
- her dog and cat together equal 54 pounds
Now you need to create the equations based on what you know:
Let's say x is her dog and y is her cat
x+y=54 (both dog & cat equal 54)
x=8y (dog is 8 times as much as cat)
Step 1 -
Put in what we know x is for our first equation and solve for y (cat):
8y+y=54 (Combine like terms)
9y=54 (Divide by 9 on each side to get y by itself)
y=6
Now we have solved for y, but we still don't know what x is.
Step 2 -
Put in y into our first equation to solve for x (dog):
x+6=54 (Subtract 6 from both sides to get x by itself)
x=48
Now we have solved for x also. So now we have both x and y.
But to check our work we just have to put the numbers into the original equations:
x+y=54 ----> 48+6=54 (Correct)
x=8y ----> 48=8(6) (Correct)
You now have your final answer. Ali's dog weighs 48 pounds and her cat weighs 6 pounds.

Hope this helped!
Answer:
The value of the function for f(-5) is 21.
Step-by-step explanation:
Consider the provided function.
[tex]f(x)=|2x-1|+10[/tex]
We need to find the value of the function for f(-5).
Substitute the value of x=-5 in the above function.
[tex]f(-5)=|2(-5)-1|+10[/tex]
[tex]f(-5)=|-10-1|+10[/tex]
[tex]f(-5)=|-11|+10[/tex]
The absolute value of -11 is 11.
[tex]f(-5)=11+10[/tex]
[tex]f(-5)=21[/tex]
Hence, the value of the function for f(-5) is 21.
