I believe the answer for the second one is B ( I took this last year but I think it’s that one)
Answer:
4x + 3y = 5
Step-by-step explanation:
Gradient = -9 -11/ 8 + 7
= -4/3
Equation of the line...
y = mx + c
y = -4/3(x + 7) + 11
Multiplying through by 3...
3y = -4x - 28 + 33
3y = -4x + 5
4x + 3y = 5
D is the answer to this question
First you combine the similar variables such as, 16T and 80T then you should come up with H=96t squared + 96 and then simplify!
