Okay add 78 and 66. Then add 96 and 108. It should be 144 by 204. I know math is hard, but when you work at it you can do amazing things! I hope that helps you.
Answer:In a function: A set of ordered pairs should not be repeating the value of x.
(2, 3), (6,-5), (-1,3) is a function.
(1,9).(-3,-2) (1,4) is not a function. It has a repeating x value.
(0,3), (0,7). (4,0) is not a function. It also has a repeating x value.
(-6,5),(-5, 6), (8, 2) is a function.

Answer:
yes
Step-by-step explanation:
The correct answer is option A. Which is the solution of the given equation will be (15,15).
<h3>What is an equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given equations are solved as:-
a - 1.2b = -3 or a = -3 + 1.2b
0.2a + 0.6b = 12
Put the value of a from equation 1 to the equation second.
0.2 ( -3 + 1.2 b) + 0.6b = 12
-0.6 + 0.24b + 0.6b = 12
0.84b = 12 + 0.6
0.84 b = 12.06
b = 15
Put the value of b in the first equation to find the value of a.
a = 1.2b - 3
a = (1.2 x 15) - 3
a = 15
Therefore the correct answer is option A. Which is the solution of the given equation will be (15,15).
