X, y - the numbers
The numbers multiply to 100.
![xy=100](https://tex.z-dn.net/?f=xy%3D100)
The numbers add up to -29.
![x+y=-29 \\ y=-x-29](https://tex.z-dn.net/?f=x%2By%3D-29%20%5C%5C%0Ay%3D-x-29)
Substitute -x-29 for y in the first equation:
![x(-x-29)=100 \\ -x^2-29x=100 \\ -x^2-29x-100=0 \\ -x^2-4x-25x-100=0 \\ -x(x+4)-25(x+4)=0 \\ (-x-25)(x+4)=0 \\ -x-25=0 \ \lor \ x+4=0 \\ x=-25 \ \lor \ x=-4 \\ \\ y=-x-29 \\ y=-(-25)-29 \ \lor \ y=-(-4)-29 \\ y=25-29 \ \lor \ y=4-29 \\ y=-4 \ \lor \ y=-25 \\ \\ (x,y)=(-25,-4) \hbox{ or } (x,y)=(-4,-25)](https://tex.z-dn.net/?f=x%28-x-29%29%3D100%20%5C%5C%0A-x%5E2-29x%3D100%20%5C%5C%0A-x%5E2-29x-100%3D0%20%5C%5C%0A-x%5E2-4x-25x-100%3D0%20%5C%5C%0A-x%28x%2B4%29-25%28x%2B4%29%3D0%20%5C%5C%0A%28-x-25%29%28x%2B4%29%3D0%20%5C%5C%0A-x-25%3D0%20%5C%20%5Clor%20%5C%20x%2B4%3D0%20%5C%5C%0Ax%3D-25%20%5C%20%5Clor%20%5C%20x%3D-4%20%5C%5C%20%5C%5C%0Ay%3D-x-29%20%5C%5C%0Ay%3D-%28-25%29-29%20%5C%20%5Clor%20%5C%20y%3D-%28-4%29-29%20%5C%5C%0Ay%3D25-29%20%5C%20%5Clor%20%5C%20y%3D4-29%20%5C%5C%0Ay%3D-4%20%5C%20%5Clor%20%5C%20y%3D-25%20%5C%5C%20%5C%5C%0A%28x%2Cy%29%3D%28-25%2C-4%29%20%5Chbox%7B%20or%20%7D%20%28x%2Cy%29%3D%28-4%2C-25%29)
The numbers are
-4 and
-25.
Answer:
D
B
Step-by-step explanation:
1. x² - 5x = 14
x² -5x -14 = 0
x² +2x -7x -14 = 0
x(x + 2) -7(x + 2) = 0
x - 7 or x + 2 = 0
x = 7 or x = -2
2. y² + 6y + 9 = 49
y² + 6y +9 -49 = 0
y² +6y -40 = 0
y² +10y -4y -40 = 0
y(y + 10) -4(y + 10) = 0
y -4 or y + 10 = 0
y = 4 or y = -10
Answer:
F 4 ^ -2
Step-by-step explanation:
4 ^ -5
-----------------
4^-3
We know that a^b/ a^c = a^ (b-c)
4 ^ (-5 - -3)
4 ^ (-5 +3)
4 ^ (-2)
