Answer:

x = 2 or x = -1/4

Step-by-step explanation:

Let's solve your equation step-by-step.

4x2−7x−2=0

For this equation: a=4, b=-7, c=-2

4x^2+−7x+−2=0

Step 1: Use quadratic formula with a=4, b=-7, c=-2.

x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}

x=\frac{-(-7)\pm\sqrt{(-7)^2-4(4)(-2)} }{2(4)}

x=\frac{7\pm\sqrt{81} }{8}

x = 2 or x = -1/4

<u>Answer:</u>

x = 2 or x = -1/4

Solve the system using substitution.
elixir [45]
Hi there...

Solve the system using substitution.
2x + 2y = 38
y = x + 3

We need to solve y = x+ 3 for y
substitute x + 3 for y in 2x + 2y = 38
2x + 2y = 38
Now replace x+3 everywhere there's y
2x + 2(x+3) = 38
2x + 2x + 6 = 38
4x + 6 = 38
4x = 38 - 6
4x = 32
x = 32/4
x = 8
Now, we have the number of x which is gonna help us find y
what we gonna do is replace 8 everywhere we see an x so we find y. Please follow me :)

Substitute 8 for x in y = x + 3
y = 8 + 3
y = 11
Final answer : x = 8 and y = 11
The correct option is A

If you have any further questions about my answer please let me know.

By the way.... I would be happy to help you with the other 10 :) 

Good luck !

Cos (a-b) - cos (a+b) = 2 sin a sin b
ollegr [7]
                                                         cos(a - b) - cos(a + b) = 2sin(a)sin(b)
 [cos(a)cos(b) + sin(a)sin(b)] - [cos(a)cos(b) - sin(a)sin(b)] = 2sin(a)sin(b)
[cos(a)cos(b) - cos(a)cos(b)] + [sin(a)sin(b) + sin(a)sin(b)] = 2sin(a)sin(b)
                                                                       2sin(a)sin(b) = 2sin(a)sin(b)
