For this all you have to do is plug in the x and y values into the equation and see if it is a true statement. If it's true then it's on the line. The x value is 2 and the y is -4.
12x + 3y = 6
12 (2) + 3 (-4) = 6
24 -12 = 6
12 = 6
The statement 12=6 is not a true statement so that point is not on the line.
The equivalent expression 2 / 7 d¹¹ for given exponential expression 6d⁻⁴ / 21 d⁷ which is determined by dividing by the GCF of 3.
<h3>What is an exponential function?</h3>
An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.
It is a relation of the form y = aˣ in mathematics, where x is the independent variable
We have been the given expression below as:
⇒ 6d⁻⁴ / 21 d⁷
To begin, divide the numerator and denominator by the GCF of 3.
If the negative exponent is relocated to the denominator, it will turn positive.
So you will have
⇒ 2 / 7 d⁷d⁴
Add the exponents because their base is the same,
⇒ 2 / 7 d⁷⁺⁴
⇒ 2 / 7 d¹¹
Therefore, the equivalent expression 2 / 7 d¹¹ for given exponential expression 6d⁻⁴ / 21 d⁷.

Answer: The price for the meal after the coupon was used is : 28.80
Explanation:
A percentage is basically a fraction, with a denominator of 100, so:
10% = 10/100
15% = 15/100
Hence, 20% is 20/100
This fraction can be reduced to 1/5
Next multiply 36 by 1/5:
36 x 1/5 = 7.2
Another way to get the answer would be dividing by the reciprocal
36 divided by the reciprocal of 1/5 is 5/1, or just 5.
5 divided by 36 is 7.2
So, just add a zero to the end: 7. 20, that number is the amount that will be taken off.
Now we do the number that is taken off minus the amount of the meal:
7.20 - 36 = 28.80
The price for the meal after the coupon was used is : 28.80
Hope this helps! :)
