<Q and <R are complementary angles. If m<Q = (31 - 3x)° and m<R = (19x - 5)°, find m<R

Sergio [31]

31-3x+19x-5=90

26+16x=90

-26 -26

--------------------

16x= 64

16x/16= 64/16

x=4

m <R=19 (4)-5= 71.

The discriminant for the equation f(x)=6x^(2)-x+c is 73. What is the value of c?

Andrews [41]

Answer:

c = -3

Step-by-step explanation:

The discriminant is 73, that means we have:

(-1)^2-4*6*c=73

then: 1-24c=73

or -24c= 73 -1

-24c = 72

Then c = 72/-24= -3

The answer is -3
