Answer:
f(x) = 2/5x^2.
Step-by-step explanation
Take the quadratic function x^2.
A vertical compression of 2/5 would transform it to:
f(x) = 2/5 x^2.
Answer: 5(5 + 9). This expression can be solved by multiplying 5 by both the addends. So, 5(5) + 5(9) = 25 + 45 = 70.
Step-by-step explanation:
Answer:
(7/4)x - 10
Step-by-step explanation:
y = mx + c
m = gradient
c = y-intercept
so you just substitute in the respective values
Step-by-step explanation:
![{x}^{2} + 14x + 24 = 0 \\ {x}^{2} + 12x + 2x + 24 = 0 \\ x(x + 12) + 2(x + 12) = 0 \\ (x + 12)(x + 2) = 0\\ x = - 12 \\ x = - 2](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%2B%2014x%20%2B%2024%20%3D%200%20%5C%5C%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%2012x%20%2B%202x%20%2B%2024%20%3D%200%20%5C%5C%20x%28x%20%2B%2012%29%20%2B%202%28x%20%2B%2012%29%20%3D%200%20%5C%5C%20%28x%20%2B%2012%29%28x%20%2B%202%29%20%20%3D%200%5C%5C%20x%20%3D%20%20-%2012%20%5C%5C%20x%20%3D%20%20-%202)
