PLEASE HELP!!!!!!!!!Let x^2+bx+c = 0 be a quadratic whose roots are each two more than the roots of 3x^2-5x-7. What is c?

Answers

Answer 1

Answer: Let $x_1 , x_2$ be the roots of the equation $3x^2-5x-7$ . By the Viet theorem you have that $\left \{ {{x_1+x_2=- (5)/(3) } \atop {x_1x_2= (-7)/(3) }} \right.$ .

For the equation $x^2+bx+c = 0$ you'll have that $c=(x_1+2)(x_2+2)=x_1x_2+2(x_1+x_2)+4=(-7)/(3)+2\cdot(- (5)/(3) )+4$
That is $(-7)/(3)- (10)/(3) +4=- (5)/(3)$ .

Answer: $- (5)/(3)$

Lexi, susie and rial are playing an online word game. Rial scores 100,034 points. Lexi scores 9,348 fewer points than rial and susie scores 9,749 more points than kexi. What is susie's score

Answers

To solve this problem, you first need to subtract 100,034-9,348. You do this because Lexi scored that many points LOWER than Rial. You then take the answer to that subtraction problem (90,696) and add 9,749 to that answer. You do this because Susie scored 9,749 MORE than Lexi. You should get 100,435. This is Susie's score, so your final answer is 100,435 points.
