Which would be the best method to use to solve the following equations. Explain your reasoning. Use each method only once. Factoring, Square root property, Completing the square, and the Quadratic formula 1. x^2- 49 = 0 2. x^2 - 3x - 4 = 0 3. x^2 - 2x - 6 = 0 4. x^2 - 17x + 7 = 0 which method would you use for each and why,? ​

answer: this doesnt make any sense especially the photo.

step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
