What are the values of a, b and c in the quadratic equation -2x^2+4x-3=0?

AlladinOne [14]

Answer:

$a=-2\\b=4\\c=-3$

Step-by-step explanation:

In a quadratic equation in the Standard form

$ax^2+bx+c=0$

You need to remember that "a", "b" and "c" are the numerical coefficients (Where "a" is the leading coefficient and it cannot be zero: $a\neq0$ ).

You can observe that the given quadratic equation is written in the Standard form mentioned before. This is:

$-2x^2+4x-3=0$

Therefore, you can identify that the values of "a", "b" and "c" are the following:

$a=-2\\b=4\\c=-3$

Emily and Kylie are 140 miles apart, traveling towards each other. If Kylie travels 12 mph and Emily travels 8 mph how long unti

Bogdan [553]

Answer: 7 hr

Step-by-step explanation:

Given

Distance between Emily and Kylie is $140\ \text{miles}$

Speed of Emily $v_e=12\ mph$

Speed of Kylie $v_k=8\ mph$

Distance traveled by Emily $\Rightarrow d_e=12t$

Distance traveled by Kylie $\Rightarrow d_k=8t$

$\Rightarrow 12t+8t=140\\\Rightarrow 20t=140\\\Rightarrow t=7\ hr$

They will meet after 7 hour.
