Answer:
You got your negatives messed up. The answer was -5y-4x
Step-by-step explanation:
Expression: -8y + 5x + 3y -9x
Your objective: Simplify the expression
The First step, Combine like terms meaning -8y+3y and -9x+5x
Solve, -8y+3y
That would equal -5y
Next solve -9x + 5x
That would equal -4x
Write your expression in simplest form:
-5y-4x
What you did:
You combined like terms but didn't follow the negative rules
Remember: Positive and Negative = Negative
Negative and Negative = Positive
For example -8y + 3y
You chose to add -8 and 3 which you got -11
What you were supposed to do was to subtract.
A helpful trick: Since they are like terms you could rearrange the questions like this 3y-8y+5x-9x, You can see that you have to do subtraction left to right
3y-8y= -5y
5x-9x= -4x
Solution: -5x-4x
Answer:
0,0 represents the y intercept
1,10 represents the slope
X = -1
Y=1
This should be the answer
C, because first of all, it is asking for m, the number of muffins, and not b, the number of blueberries. So, we can eliminate b and d. Now we can decide between A and C.A) is m=b+144, and it is is false because it will not work for all of the table. C is now our only option, so it is correct. :) Hope this helps!!! :)
At time t = 1 hr... fee is initial ($12)+ ($8) = 20
<span>and so on... the intercept would be initial fee... which is $12 charged at t=0 hr
</span>
8$ per hour is the essentially the slope
<span>12 is the initial charge also known as the y-intercept </span>
<span>y = 8x + 12 </span>
where y is the total charge and x is the number of hours
hope it helps
