Answer:
d= 4t
Step-by-step explanation:
to find distance, the equation is speed multiplied by time and in this question we are given the time and distance so we have to divide 9km by 2.25hrs to find the speed: 9÷2.25= 4 so, the equation would be d=4t which means that to find distance we need to multiply 4 by the time.
If the 0 and 2 are powers it would be 16^0=1, 2^2=4
Now we have 1+4*y-1.
Im not sure if you want parenthesis to make it 1+4(y-1) or not.
Solving for the first one it would simplify to 4y.
With the parenthesis it would be 4y-3.
Thats it simplified, if it is equal to something you would solve for y.
