Solve 12x- 6y = 18 for y.
The given equation solved for y as y=2x-3.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is 12x-6y=18.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
The equation can be solved as follows
6(2x-y)=18
⇒ 2x-y=3
⇒ y=2x-3
Therefore, the given equation solved for y as y=2x-3.

PLEASE HELP!!
Guys please help i need this
Answer:
Because they are both base angles of isosceles triangles
For all horizontal lines the range is
When you have a function where y equals a constant, your graph is a truly horizontal line,
In that case, the range is just that one and only value. No other possible values can come out of that function! Many other functions have limited ranges.

Answer:
Algebra is a branch of mathematics that substitutes letters for numbers. Algebra is about finding the unknown or putting real-life variables into equations and then solving them. Algebra can include real and complex numbers, matrices, and vectors. An algebraic equation represents a scale where what is done on one side of the scale is also done to the other and numbers act as constants.
Expressions is a Numbers, symbols and operators (such as + and ×) grouped together that show the value of something.
Examples:
• 2 + 3 is an expression

A function f(x) has an inverse, or is one-to-one, if and only if the graph y = f(x) passes the horizontal line test. A graph represents a one-to-one function if and only if it passes both the vertical and the horizontal line tests.
A cone with a radius of 3 feet and a height of 5 feet is placed on top of a cylinder as shown. Find the volume of the total figure in terms of pi
Answer:
5π
Step-by-step explanation:
v=1/3πrh
v=1/3×π×3×5=5π
The volume of the combined solid is given as 69π ft³.
What is a right circular cylinder?A right circular cylinder is a three dimensional figure having its base and top as a circle and the height is perpendicular to circular base. The volume is given as V = πr²h.
The volume of the combined solid is given as,
Volume of cone + Volume of cylinder
The expression can be written as,
1/3πr²h + πr²H
Where h and H are the heights of cone and cylinder respectively.
Plug r = 3, h = 5 and H = 6 to obtain as,
⇒ 1/3π × 3² × 5 + π × 3² × 6
⇒ 69π
Hence, the volume of the combined solid is obtained as 69π ft³.

Two angles form a linear pair. The measure of one angle is twice the measure of the other angle. Find the measure of each angle.
The smaller angle measures =?
The larger angle measures =?
Answer:
The smaller angle measures = 60º
The larger angle measures = 120º
Step-by-step explanation:
The sum of angles in linear pair is 180
The measure of one angle is twice the measure of the other angle.
x + 2x = 180
Combine like terms
3x = 180
Divide both sides by 3
x = 60º
2x = 120º

Step-by-step explanation:
Answer:
x = 146°
Step-by-step explanation:
this shape is a rhombus and one property is that adjacent angles are supplementary
therefore, 'x' + 34 = 180
'x' = 180-34
'x' = 146

1.5a + 6 = 9a + 12
please answer quick i hate math
Answer:
-0.8
Step-by-step explanation:
First move the variable terms to one side of the equal sign. I always move the smallest to the largest.
[tex]1.5a + 6 = 9a + 12 \\ - 1.5a \: \: \: \: \: \: \: \: \ \: - 1.5a[/tex]
Solve and move the constants to opposite side. I'm going to subtract 12 from both sides.
[tex] 6 = 7.5a + 12 \\ - 12 \: \: - 12[/tex]
Now solve for a by dividing both sides by 7.5
[tex] \frac{ - 6}{7.5} = \frac{7.5a}{7.5} [/tex]
[tex]a = - 0.8[/tex]
