For y=-3sin (x)-2 it's C
Step-by-step explanation:
Step-by-step explanation:
The difference is 1 times +3 is like 1×3=3
Unlike 1 times 1 + 3 =1×1+3=4
Answer:
7x^2+10y^2-2x is the correct answer, Marcus put -10y INSTEAD of +10y^2
Step-by-step explanation:
(3x^2-2y^2+5x)+(4x^2+12y^2-7x)
Combine like terms- I'll add x^2 first, then y^2, and then finally x, and it will be in that order.
7x^2+10y^2-2x
Make sure to check your signs are correct, and you wrote down the proper exponents.
