Divide both sides of this eq'n by -9. You'll get y = -1.
Answer:
40-9x+4x+5=
45-5x
You can't do anything else because the variables are different.
5/8 = x/32
8 x 4 = 32
5 x 4 = 20
5/8 = 20/32
x = 20

Solution:</h3>
A linear function is a straight line formed on a coordinate plane.
<u>To classify an equation as a linear function:</u>
- It must not have any exponent in the equation.
- If there is a fraction, the denominator of that fraction must not multiply by x.
If any of these two occurs in an equation, the line can form a curve in a line, which is a non-linear function. A non-linear function is a curved line formed on a coordinate plane.
<u>Option A - y = x³ + 1:</u>
- This equation has an exponent in the variable x. Hence, this is a non-linear function.
<u>Option B - 5x/6 = y - 4:</u>
- This equation has no exponents in the equation. Hence, this is a linear function and also our answer.
<u>Option C - y = 8x²</u>
- This equation has an exponent in the term 8x². Hence, this is a non-linear function.
<u>Option D - y = 1/5x</u>
- The denominator of the fraction on the RHS side is multiplied by x. Hence, this is not a linear function.
Hence, Option B is correct.

What is real number?</h3>
Real numbers are numbers that include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers.
Given that:
The given option are
-2.3456 =-23456/10000
since, -2.3456 can be represented as rational numbers.
π is an infinite decimal, so it cannot be expressed as a rational number.
So, 1/4 π is irrational number.
is an irrational number.
2 + √16=2+4= 6 is a rational number.
Therefore, the number are 1/4 π and
are irrational number.
