Solve for y.
1+ 2y = 11.08 +0.2y
Answer:
y=5.6
Step-by-step explanation:
1 + 2y = 11.08 +0.2y
Move the values w/ y all to one side and the ones without to the other side
1+ 2y = 11.08 + 0.2y
-0.2y - 0.2y
-1 -1
1.8y=10.08
Divide by 1.8
y=5.6
2x+4=3x-2 solve for x
Answer:
x = 6
Step-by-step explanation:
2x + 4 = 3x - 2
2x - 3x = -2 - 4
-x = -6
x = 6
Answer:
x = 6
Step-by-step explanation:
We are given this equation:
2x + 4 = 3x - 2
And we want to evaluate the equation for x.
To do this, we need to isolate the variable (x) on one side of the equation.
We can start by putting the numbers on one side.
We can subtract 4 from both sides of the equation to start. Remember that when solving equations, whatever we do on one side of the equation, we need to do it on the other side as well.
2x + 4 = 3x - 2
-4 -4
___________________
2x = 3x - 6
Now, let's put the variables on the other side.
Subtract 3x from both sides.
2x = 3x - 6
-3x -3x
______________
-x = -6
Now, the numbers and variables are on different sides, however we are not done yet, as we need to take care of the negatives, as x shouldn't be negative in this case.
-x is the same as -1x, or -1 * x.
So, in order to get rid of the negatives, we can either multiply or divide both sides by -1.
Let's multiply both sides by -1.
-1(-x) = -1(-6)
x = 6
The value of x is 6.
how can you apply the Laws of Exponents to evaluate expressions that include integer exponents?
Exponent rules are those laws that are applied to exponent-based expressions to make them simpler. The principles of exponents make it simple and rapid to execute numerous arithmetic operations like addition, subtraction, multiplication, and division. These guidelines are also useful for reducing the complexity of numbers that have complex powers incorporating fractions, decimals, and roots.
Exponent rules, commonly referred to as the "laws of exponents" or "properties of exponents," facilitate the task of simplifying exponent-based statements. These guidelines are useful for reducing the complexity of expressions whose exponents are decimals, fractions, irrational numbers, or negative integers.
When an exponent is a negative number, we apply the negative law of exponents. This rule states, "The reciprocal should be taken to convert any negative exponent into a positive exponent." The change in sign of the exponent values moves the expression from the numerator to the denominator.

Given the system of equations:
6x + 2y = −6
3x − 4y = −18
Solve for (x, y) using elimination.
(0, −3)
(−1, 0)
(−2, 3)
(−14, −6)
Answer:
(- 2, 3 )
Step-by-step explanation:
6x + 2y = - 6 → (1)
3x - 4y = - 18 → (2)
multiplying (1) by 2 and adding to (2) will eliminate y
12x + 4y = - 12 → (3)
add (2) and (3( term by term to eliminate y
15x + 0 = - 30
15x = - 30 ( divide both sides by 15 )
x = - 2
substitute x = - 2 into either of the 2 equations and solve for y
substituting into (1)
6(- 2) + 2y = - 6
- 12 + 2y = - 6 ( add 12 to both sides )
2y = 6 ( divide both sides by 2 )
y = 3

p(z) = 3r+4
q(z) = 2z²
Find p (q(z))
The value of the function p (q(z)) is 6z² +4 .
By considering the given functions
p(z) = 3r+4
q(z) = 2z²
p (q(z))= p( 2z²)
p (q(z))= 3(2z²)+4

f+an=g Solve for 'a'.
Answer:
a= [tex]\frac{g-f}{n}[/tex]
Step-by-step explanation:
First, start off by subtracting f from both sides. This gives you "g - f" and you are left with "an." Now, to isolate the variable, we must divide "n" from both sides and you will get "a= g - f/n," which is the final answer.

Answer:
42, 12)
Step-by-step explanation:
Let the present ages of the father and son be x years and y years respectively.
According to the question,
Condition I,
Three years ago the sum of the ages of the father and his son was 48 years.
or,(x−3)+(y−3)=48
or,x−3+y−3=48
or,x−6=48−y
or,x=54−y - (i)
Condition II,
Three years hence the father's age will be three times the son's age,
or,(x+3)=3(y+3)
or,x+3=3y+9 - (ii)
Put value of x from equation (i) in equation (ii), we get,
or,(54−y)+3=3y+9
or,54−y=3y+9−3
or,54−6=3y+y
or,48=4y
or,y=484
∴y=12
Put the value of y in equation (i), we get,
or,x=54−12
∴x=42
So, (x,y) = (42, 12)
Therefore, the required present ages of the father and the son are 42 years and 12 years respectively.
is y=x+8 a inverse variation
It should be noted that y=x+8 is not an inverse variation.
What is an inverse relation?The relationships between variables that are expressed in the form of y = k/x, where x and y are two variables and k is a constant number, are known as inverse variations. According to this statement, if the value of one item rises, the value of the other quantity falls.
Ab example is when a constant of variation is k = xy = 5(2) = 10 if y changes inversely as x and x = 5 when y = 2. Consequently, xy = 10 is the equation that describes this inverse variation.
Therefore, it should be noted that y=x+8 is not an inverse variation.

lundefined
The slope of the line is zero.
The increase divided by the run, or the ratio of the rise to the run, is known as the line's slope or gradient. In the coordinate plane, it represents the slope of the line.
In the general equation of a line y= mx + c , m denotes the slope of the line.Slope of a line is calculated by the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}.[/tex] If a straight line makes an angle θ with the positive x-axis then the slope of the line is given by m = tanθFrom the given figure we can see that the line is parallel to the x-axis.
Any line parallel to the x-axis is given by the general equation y = a .
This equation can also be written as:
y = 0 x + a.
Comparing the above equation with the general equation of a straight line y = mx + c
we see m = 0 and c = a (a is a constant)
Hence the slope of the line is 0.

What is the Corresponding Angles Theorem?The corresponding angles that are formed when two parallel lines are intersected by a transversal are congruent, according to the corresponding angles theorem.
Given that lines m and n are parallel lines that are intersected by transversal t, therefore:
2x + 9 = 7x + 24
Solve for x
2x + 9 - 9 = 7x + 24 - 9 [subtraction property of equality]
2x = 7x + 15
2x - 7x = 7x + 15 - 7x [subtraction property of equality]
