Complete the ordered pair for the equation y=-10x+18 I have one of the ordered numbers given to me by my instructor, I have to come up with the first one, this is excactly how he gave it to me, but I really don't understand this...Can someone please help me understand it better? (_, 78)
_ is the x value, 78 is the y value.
Substitute 78 for y and solve the equation given for x. The answer I obtained is -6 but check my work.
To find the first number in the ordered pair (x, 78), we can use the equation y = -10x + 18 and substitute y with 78.
So, we have:
78 = -10x + 18
To solve for x, we need to isolate it on one side of the equation. We'll start by subtracting 18 from both sides:
78 - 18 = -10x
Simplifying:
60 = -10x
Next, divide both sides of the equation by -10 to solve for x:
60 / -10 = x
-6 = x
Therefore, the first number in the ordered pair is -6.
The complete ordered pair for the equation y = -10x + 18 is (-6, 78).
To find the missing value in the ordered pair for the equation y = -10x + 18, we need to substitute the given y-value, 78, into the equation and solve for x.
Start by replacing y with 78 in the equation:
78 = -10x + 18
To solve for x, we need to isolate the variable on one side of the equation. Start by subtracting 18 from both sides:
78 - 18 = -10x + 18 - 18
60 = -10x
Next, divide both sides of the equation by -10 to solve for x:
60 / -10 = -10x / -10
-6 = x
Now we know that the missing value in the ordered pair is (-6, 78). So the complete ordered pair for the equation y = -10x + 18 is (-6, 78).
