Which expression is equivalent to 15 + 6x?
Answers
Answer:
Step-by-step explanation:
The expression 15 + 6x can be simplified further. The term 15 is a constant because it does not contain a variable. On the other hand, 6x is a variable term because it contains the variable x.
To simplify the expression, you can combine like terms by adding or subtracting the coefficients of the variable terms. In this case, you can't combine 15 and 6x because they are not like terms.
Therefore, the expression 15 + 6x is already simplified and does not have an equivalent expression. It represents the sum of 15 and 6 times x.

By the Definition of congruent property, we have proved that:
VW ≅ VX
Congruent Property:
The three properties of congruence are the reflexive property of congruence, the symmetric property of congruence and the transitive property of congruence. These properties can be applied to line segments, angles, triangles, or any other shape.
Given: VZ ≅ VY and WY ≅ XZ
Prove: VW ≅ VX
Proof:
(Given): VZ ≅ VY and WY ≅ XZ
By the Definition of Congruent Substitute:
VZ = VY and WY = XZ
⇒ VZ = VX + XZ , and,
VY = VW + WY
By Substituting
VX + XZ = VW + WY
Again,
VX + WY = VW + WY
Now,
By Subtraction property of Equality
VX = VW
VW = VX (Definition of congruent property.)
Complete Question:
IF VZ congruent of VY and WY congruent of XZ. Prove that VW is Congruent of VX.

Your equation is [ y = x + 1 ].
You want to know whether (5, 6) is A solution to the equation.
When you write (5, 6), that means "x=5 and y=6".
So put those numbers into the equation in place of 'x' and 'y'
and see if the equation is true after you do that.
(y) = (x) + 1
(6) = (5) + 1
Do you see 5+1 on the right side. That's 6.
So the equation says " 6 = 6 " . . . a true statement.
So (5, 6) is a solution of the equation.
It's not THE solution. There are an infinite number of solutions
to that equation. (5, 6) is one of them.

Angles in a triangle may or may not be congruent.
The values of x and y are 90 and 47, respectively.
From the figure, we have:
This means that, angle x is a right-angle.
So, we have:
Triangle ABC is an isosceles triangle.
So, we have:
The measure of y is then calculated as:
--- sum of angles in a triangle
This gives
Subtract 137 from both sides
Hence, the values of x and y are 90 and 47, respectively.

Recall the properties of Isosceles Triangle:
An isosceles triangle has equal base angles an two equal legs that are opposite the base angles.
Triangle ABC is an isosceles triangle.
- Therefore:
m<ACD = m<ABD = 47 degrees
Find y:
- Substitute
y = 1/2(180 - (47 + 47))
y = 43 degrees.
Find x:
x = 180 - (y + m<ABD)
- Substitute
x = 180 - (43 + 47) (sum of triangle)
x = 90 degrees
Therefore, applying the properties of Isosceles triangle and the sum of triangle theorem, the values of x and y in the image given are:
