Can someone please help me on this??

Usimov [2.4K]

Answer:

Step-by-step explanation:

To solve this use the equation $x^2 -15x - 50 = y$ given in the problem and the value y = 50. Substitute y = 50 then solve for x by factoring.

$x^2 -15x - 50 = 50\\x^2 - 15x -100 = 0$

Find two numbers which multiply to -100 and also add to -15. The numbers are -20 and 5.

So the factored form is (x-20)(x+5) = 0.

Set each factor equal to 0 and solve.

(x-20) = 0 so x = 20.

(x+5)=0 so x = -5.

This means the temperature is 20 degrees C or -5 degrees C. Only 20 is an option. The solutions is C.
