= cos(x-π/2)/sin(x-π/2)
= (cos(x)cos(π/2) + sin((x)sin(π/2)) / (sin(x)cos(π/2) - cos(x)sin(π/2)
= sin(x)/ (-cos(x)) .... cos(π/2) = 0; sin(π/2) = 1
= -tan(x)
idk if this is right but i tried
There is a common entity between the two terms of the given expression and that is the number 2 before each variable. We can factor out the 2 from the given expression and it becomes,
2 x (a + b)
Step-by-step explanation:
..........I think the answer is 80.

Answer:
The correct option is a=5, b = -4, c=7 ....
Step-by-step explanation:
The standard form is ax²+bx+c=0
where a, b, and c being constants, or numerical coefficients, and x is an unknown variable.
The given expression is:
4x + 5x2 = 8x – 7
To make it a standard equation we will move all the values to the left hand side and 0 will be left at the right hand side.
4x+5x²-8x+7=0
Now solve the like terms and arrange the equation according to the standard form:
ax²+bx+c=0
5x² - 4x +7 =0
Here a = 5
b = -4
c= 7
Thus the correct option is a=5, b = -4, c=7 ....
Answer:
5.25 miles.
Step-by-step explanation:
What I did was I took 3/4 and made it into its decimal form which is 3/4. I then times it by 7 to get 5.25.
5.25 miles is your answer.
