Answer:
The value of y by itself in the equation x+2y=10 is
Step-by-step explanation:
Given equation is x+2y=10 -------- (1)
To find y with given equation as below :
Equation (1) implies that x+2y=10
Subtracting the above equation by x we get
x+2y-x=10-x
x-x+2y=10-x
2y=10-x
Dividing by 2 on both sides we get
Therefore the value of y is
Therefore the value of y by itself in the equation x+2y=10 is

Answer:
- reflection over y = 2.5
- translation left 1
Step-by-step explanation:
The orientation of the triangle is reversed, so a reflection is required. Horizontal lines remain horizontal, but up/down are reversed, so the reflection is across a horizontal line. The horizontal line that is halfway between each point and its image is the line y = 2.5.
The x-coordinates of the image points are 1 less than the x-coordinates of the original, so a left shift of 1 unit is involved.
The two transformations to get from A to B could be (in any order) ...
- reflection over the line y = 2.5
- translation left 1 unit
__
The transformation can be summarized by ...
(x, y) ⇒ (x -1, 5 -y)

Roots:
x = , or x= -10
Step-by-step explanation:
A quadratic fomrual in standard form is;
ax^(2) + bx + c = 0
The given equation:
4x^2 = -9x - 4
Maniplate the equation using inverse operations
4x^2 = -9x - 4
-4x^2 -4x^2
0 = -4x^2 - 9x - 4
Yes, this is a quadratic equation, because it fits the requirement of being able to be written in standard form.
Now find its roots:
-4x^2 -9x - 4 = 0
remember,
x =
Substitute in the given values
x=
Simplify,
x =
x =
x =
or
x= -10
