Two times the sum of nine and a number is the opposite of 9.
Write an equation and solve.
Answers
The number is -27/2 if two times the sum of nine and a number is the opposite of 9 after applying the concept of the linear equation.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Two times the sum of nine and a number is the opposite of 9.
Let the number be x:
2(x + 9) = -9
2x + 18 = -9
2x = - 9 - 18
2x =- 27
x = -27/2
Thus, the number is -27/2 if two times the sum of nine and a number is the opposite of 9 after applying the concept of the linear equation.

This is because you have "two times" which is 2*
The sum of a number = x
Opposite of 9 = -9

g(x) =
Step-by-step explanation:
Exponential function 'g' that can be written as g(x) = a.bˣ
From the graph attached,
Graph of the function passes through two points (0, 9) and (1, 3)
g(0) = a.b⁰
9 = a
Similarly, g(1) = a.b¹
3 = a.b
3 = 9(b)
b =

Answers
Answer: ∠S = ∠X.
Step-by-step explanation:
Since we have given that
∠RST and ∠WXY
WE need to find the corresponding part of ∠S.
As we have given RST and WXY,
Corresponding part means a pair of matching sides or angles that are in the same side in two different shapes.
So,According to question,
Corresponding angle to ∠S is ∠X.
Hence, ∠S = ∠X.

Amount of sugar in the cabinet of Cassie = 1/2 pound
Amount of sugar required by Cassie to make her cake recipe = 2/10 pound
= 1/5 pounds
Then
The number of cakes that Cassie can make = (1/2)/(1/5)
= 5/2
= 2 1/2
So from the above deduction we can easily conclude that Cassie can make a total of 2 cakes with the sugar she has and there will still be some sugar left.
Answer:2cakes

RT = 2(RX)
WX = 2(RX)
RT + TW = RX

This statement must be true as RT + TW = WX + TW, which is correct option (A).
What are congruent triangles?
Two triangles are said to be congruent if their corresponding sides and angles are equal.
SSS stands for Side-Side-Side criterion. According to this, two triangles are congruent if three sides of a triangle are equal to the corresponding sides of the other triangle.
Since RT ≅ WX, RT and WX are represent congruent
So we can say that for all kinds of reasons, they are absolutely equal.
Given that, we can substitute RT with WX in the equations and solve them to check which one is valid. The valid equation will be to true statement.
For RT + TW = WX + TW
Substitute RT = WX in the equation
RT + TW = WX + TW
WX + TW = WX + TW
Subtract TW from both sides of the equation
WX + TW - TW = WX + TW -TW
WX = WX
Since RT ≅ WX,
Therefore RT and WX are exactly equivalent and interchangeable as a result, the equation WX = WX is true..
Hence, this statement must be true as RT + TW = WX + TW
