Answer:
7c^2d-7c+4d-10
Step-by-step explanation:
Start off with the term that has c^2 in it. 5c^2d + 2C = 7c^2d, then since you have multiple choice, the d value differs between the two answer choices that have 7c^2d so you can do +3d +d to get +4d to get the fourth answer choice.
To check your work, you can add/subtract each term to see if you get 7c^2d-7c+4d-10
Answer:
5/b
Step-by-step explanation:
you would want to add your 1+4 together on top of your b which is your common denominator in this case and you should end up with 5/b
Answer:
7
Step-by-step explanation:
Or 7/1. the equation is y = mx + b. m is the slope. b is the y intercept. so m (the slope) would be 7. And b (the y intercept) would be -9.
Answer:
I think it's a but I'm not 100 percent sure but I'd say a
