Answer: y= -x-5
Step 1: Determine which equation to change
Since we will be using the substitution method, we will need to substitute y from the bottom equation with information from the top equation. This will be the equation we change.
Step 2: Change the equation
Let’s rewrite the equation we will be working with.
3x+3y= -15
Our goal will be to get y alone on the left side. To start, let’s subtract 3x from both sides, leaving only 3y on the left side.
3x+3y= -15
3y= -3x-15
Now we need to get y completely alone by eliminating the coefficient of 3. Let’s do this by dividing each term by 3.
3y= -3x-15
y= -x-5
This is your answer. Hope this helps! Comment below for more questions.
Answer: B (-12, 15)
Step: (3×-4) =-12
And (3×5)= 15
Answer:
-0.5 and 5.5
Step-by-step explanation:
removing absolute value will yield two equation: 2.5-y=3 and 2.5-y=-3
solve for y in both case.
It would show the average time spent on the homework.
And the average distance between the mean and the lowest and highest numbers in the data.
The answer is 326. this is simple.
