B? I’m sorry if I got it wrong
Answer:
1 equation) make a point on the y axis at (0,4) then draw a horizontal line.
2 equation) make a point on the y axis at (0,3) then count up 1 from the point and to the left one, and continue until you have as many points as you need.
Step-by-step explanation:
For the first equation you would simplify the problem first. Since -7+3 is -4 the first equation is y=-4
For the second equation the problem is already simplified so you would just graph.
Answer: The correct option is C.
Explanation:
It is given that Jonas made the following matrix of temperatures for the first 4 days of January and for the first 4 days of February.
Let the matrix A and B represents the temperatures for the first 4 days of January and February respectively.


The difference of January and February is defined by the matrix A-B.
To subtract two matrices, we subtract all the corresponding elements.


It is the option C.
Well the 9 is in the tens place so the value of 9 is 90
