The correct answer is: D. (-3) + 2 = -1
The other ones result in a positive sum:
A: 7 + (-5) = 2
B: 1 + (-1) = 0
C: (-3) + 4 = 1
I think your answer is 1,800
The sum of these numbers is 1771, so if you round up or down, whichever is closest, then you would get a total of 1,800.
I hope this helps!
A scale factor of 3 was used
The slope is rise/run, so if you count it in the graph, you’ll see that it’s 3/2. Also, the y-intercept (where the graph crosses the y axis) is 1. So the answer is y=3/2x-1.
(It looks like you may have accidentally typed answers C and D as the same.)
Answer:
(5,-1)
x=5
y= -1
Step-by-step explanation:
To solve this we're going to solve for one variable in either equation
so we have
x+y=4
We can subtract y and 4 from both sides to get
x-4= -y
Then divide by -1 so that y will be a positive number
-x+4=y
We can plug this in for y in the other equation
2x -2(-x+4)=12
Distribute the -2 and get
2x+2x-8=12
Combine like terms and add 8 to get
4x=20
divide and get x=5
Plug in x=5 into the first equation to get
5+y=4
subtract 5 to get y= -1
Our answer is (5,-1) or x=5 y= -1
I checked this on desmos and the math is correct
