The answer is B because if the result is 3/4 and the question is asking to the result then you would an equation.
Answer:
![\large\boxed{(f-g)(x)=-5x^2+2x+1}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%28f-g%29%28x%29%3D-5x%5E2%2B2x%2B1%7D)
Step-by-step explanation:
![(f-g)(x)=f(x)-g(x)\\\\\text{We have}\ f(x)=-2x^2-2x-3\ \text{and}\ g(x)=3x^2-4x-4.\\\\\text{Substitute:}\\\\(f-g)(x)=(-2x^2-2x-3)-(3x^2-4x-4)\\\\(f-g)(x)=-2x^2-2x-3-3x^2+4x+4\qquad\text{combine like terms}\\\\(f-g)(x)=(-2x^2-3x^2)+(-2x+4x)+(-3+4)\\\\(f-g)(x)=-5x^2+2x+1](https://tex.z-dn.net/?f=%28f-g%29%28x%29%3Df%28x%29-g%28x%29%5C%5C%5C%5C%5Ctext%7BWe%20have%7D%5C%20f%28x%29%3D-2x%5E2-2x-3%5C%20%5Ctext%7Band%7D%5C%20g%28x%29%3D3x%5E2-4x-4.%5C%5C%5C%5C%5Ctext%7BSubstitute%3A%7D%5C%5C%5C%5C%28f-g%29%28x%29%3D%28-2x%5E2-2x-3%29-%283x%5E2-4x-4%29%5C%5C%5C%5C%28f-g%29%28x%29%3D-2x%5E2-2x-3-3x%5E2%2B4x%2B4%5Cqquad%5Ctext%7Bcombine%20like%20terms%7D%5C%5C%5C%5C%28f-g%29%28x%29%3D%28-2x%5E2-3x%5E2%29%2B%28-2x%2B4x%29%2B%28-3%2B4%29%5C%5C%5C%5C%28f-g%29%28x%29%3D-5x%5E2%2B2x%2B1)
This is one of the special right triangles known as a 30, 60, 90 triangle. (Characterized by its angles)
In these triangles, the shortest leg is HALF the length of the hypotenuse.
The longest leg is (√3) times the length of the short leg.
Therefore, the shortest leg is 20, and the longest leg is 20(√3)
FINAL ANSWER:
SHORT LEG: 20 units
LONG LEG: 20√3 units
The answer is A because the bigger/ larger the Apple the longer time it takes to eat it
Answer:
1) y = -2x - 1
2) y = -3/4 + 3
3) y = 4x + 9
4) y = - 5/3x - 2
Step-by-step explanation:
b = y - m*x
1) (-7,13) and slope: -2
b = 13 - (-2)*(-7)
b = 13 - 14
b = -1
2) (4,6) lope = -3/4
b = 6 - (-3/4)*(-4)
b = 6 - 3
b = 3
y = -3/4x + 3
3) (-5,-11) and (3,-7)
Slope: (1 - - 11)/(-2 - - 5) = 12/3
= 4
b = -11 - (4) (-5) = 9
b = 9
4) slope = (-7 - 8)/(3- - 6)
= -15/9 = - 5/3
b = 8 - (-5/3)*(-6)
b = 8 - 10
b = -2
