Simplifying
12x + 2y = 18
Solving
12x + 2y = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
12x + 2y + -2y = 18 + -2y
Combine like terms: 2y + -2y = 0
12x + 0 = 18 + -2y
12x = 18 + -2y
Divide each side by '12'.
x = 1.5 + -0.1666666667y
Simplifying
x = 1.5 + -0.1666666667y
Answer:
Hi
Step-by-step explanation:
First, you need to subtract both sides by 12x
12x+ 2y=18
-12x -12x
That will give you: 2y= 18-12x
Next, you need to deviede both sides by 2
2y/2= 18-12x/2
That gives you the answer:
y= 18-6x

Find the value of x in the equation below 5= x/6
Answer:
x=30
Step-by-step explanation:
Answer:
x=30
Step-by-step explanation:
To find the value of x in an equation, our goal is always to isolate it so that it's on one side of the equal sign while everything else is on the other. We can do this by performing inverse operations to cancel values out (for example, the inverse operation of addition is subtraction and the inverse operation of division is multiplication).
5=x/6
Because x is being divided by 6, we multiply both sides by 6 to cancel it out on the side with x.
5×6=(x/6)×6
5×6=x
30=x

1/3y y = 15
please help
Answer:
Step-by-step explanation:
y in (-oo:+oo)
(1/3)*y = 15 // - 15
(1/3)*y-15 = 0
1/3*y-15 = 0 // + 15
1/3*y = 15 // : 1/3
y = 15/1/3
y = 45
y = 45
Answer: The answer is five
Step-by-step explanation: This is because if the equasion is 1/3 x y and y=15 than the equasion is 1/3 x 15 or 1/3 x 15/1 which is 5

Answer:
Quadratic
Step-by-step explanation:
A quadratic equation is an equation that contains an input variable to the second degree. This means that one of the (x) variables is squared. The given equation satisfies this condition (with its term ([tex]3x^{2}[/tex])), and therefore it is a quadratic equation.

DOGS During a recent visit to the veterinarian's office, Mrs. Cho was informed that a healthy weight for her cat is approximately 35 pounds, plus or minus three pounds. Write an absolute value inequality that represents healthy weights w for her dog.
Answer:
Step-by-step explanation:
from the given information:
The healthy weight of the cat = 35 pounds
with +/- 3
To write the absolute value;
The healthy weight will either be less or greater.
So; w > 35 +3 or w < 35 - 3
w - 35 > 3 or w - 35 < -3
Thus, the healthy weight will be |w - 35| > 3

What are the zeros of the polynomial function? State the multiplicity of each zero y=(x+2)(x-3)^2
Answ er:
-2, 3
Step-b y-step explanation:
The question is asking what x equals that makes y equals 0
How do we do this?
Because we're multiplying things together we just need one part of the equation to equal 0
for example if x= -2 then we would have the following
(-2+2)(-2-3)^2
(0)(-5)^2
which is 0
and the other answer is 3 because when you have
x-3=0
x= 3
