The value of x from the given equation is -2.

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 4(x - 2) + 3 = 2x - 9.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

4x-8+3=2x-9

4x-5=2x-9

4x-2x=-9+5

2x=-4

x=-2

Therefore, the value of x from the given equation is -2.

Answer:

7 in

Step-by-step explanation:

Step one:

Given data

A candle that is 10 inches tall burns at a rate of 1/4 inches per hour

let the number of hours take to burn completely be x

and the lenght after certain time be y

So

The expression for the situation is

y= 10-1/4x

y= 10-0.25x

for x= 12

y=10-0.25*12

y=10-3

y= 7 in

After 12 hours the length is 7 in

Answer:

y = 4

Step-by-step explanation:

y + 6 = 5(2 - 4)

y + 6 = 10 - 20

y + 6 = 10

y + 6 - 6 = 10 - 6

y = 10 - 6

y = 4

Answer:

y = -16

Step-by-step explanation:

Answer:

1/2(8x-6)=-1/3(9x-12)

We move all terms to the left:

1/2(8x-6)-(-1/3(9x-12))=0

Domain of the equation: 2(8x-6)!=0

x∈R

Domain of the equation: 3(9x-12))!=0

x∈R

We calculate fractions

(3x9/(2(8x-6)*3(9x-12)))+(-(-2x8)/(2(8x-6)*3(9x-12)))=0

We calculate terms in parentheses: +(3x9/(2(8x-6)*3(9x-12))), so:

3x9/(2(8x-6)*3(9x-12))

We multiply all the terms by the denominator

3x9

We add all the numbers together, and all the variables

3x^9

We do not support expression: x^9

Answer:

1

Step-by-step explanation:

First, we have to make the fractions improper.

To this we would need to multiply the denominator by the whole number and add it to the numerator. 2*4 is 8.  8 + 5 is 13. So for the first fraction, it will be 13/5. Let’s do the second fraction. 2*4 is 8. 8 + 3 is 11. So for the second fraction, it will be 11/2. Since the fractions have the same denominator, we will not have to do anything to them. Now, all you have to do is simple subtraction. 13 - 11 is 2. Since the denominators are the same, it will equal to 2. So the final answer is 2/2 or 1.

Answer:

8, 2, 4

Step-by-step explanation:

All the y values of a function are its range and all the x values are its domain

Since the y values of the functions are 8, 2, and -4. the range of this function{(4,8), (9,2), (-3,-4)} will be 8, 2, -4.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

All the y values of a function are its range and all the x values are its domain

All y's potential values are referred to as the function's range. Using the formula y = f(x), one may determine a function's range (x). If there is just one y value for each x value in a relation, then it is merely a function.

The y values of the functions are 8, 2, and -4.

Thus, since the y values of the functions are 8, 2, and -4. the ranges of this function{(4,8), (9,2), (-3,-4)} will be 8, 2, -4.
