Actually Welcome to the Concept of the straight lines.
y-y1 = m(x-x1) + C
====> y - 1 = 3(x - 2)
====> y-1 = 3x -6
====> y = 3x - 5
hence the equation is y = 3x - 5
Answer:
tan²A
Step-by-step explanation:
1+tan²A/1+cot²A Simplify 1+tan²A first
sec²A/1+cot²A Now simplify 1+cot²A
sec²A/csc²A Simplify sec²A and csc²A
/
Simplify the fraction
sin²A/cos²A = tan²A

For the answer to the question above,
2x + 4y = –7 (1)
y = -1/2x + 5 (2)
Putting (2) into (1), we have:
-2x + 4(-1/2x + 5) = -7
-2x - 2x + 5 = -7
-4x = -7 - 5 = -12
x = -12/-4 = 3
y = -1/2(3) + 5 = -3/2 + 5 = 7/2
Therefore there is only one solution
I hoipe my answer helped you. Feel free to ask more questions. Have a nice day!
167.462 because you can round up the 4 to a 5 because the second number is 5 or up.
<span>a)
Acceleration of stone = 10
Integrate:
So velocity = 10t
Integrate again:
So distance from starting point = 5t^2
Distance from ground = 450-5t^2
b)
450 - 5t^2 = 0
9.48 seconds
c) velocity = 10t
Put the time into this to give:
94.8 m/s
d.
Velocity = 10t + 5
Integrate again:
5t^2 + 5t
Solve
5t^2 + 5t = 450
Gives 9 seconds</span>
