Let g(x) = 2x2 - 11x. Find g(1).<br> A) -13 <br> B) -9 <br> C) 9 <br> D) 11
ratelena [41]

Answer:

(B) -9

Step-by-step explanation:

g(x) = 2x² - 11x

To find g(1), we substitute x = 1 into g(x).

g(x) = 2x² - 11x

g(1) = 2(1)² - 11(1) = 2 - 11 = -9

Simultaneous equations no idea somebody help !
vodka [1.7K]

5r + 6s = 53

25r + 3s = 49

Meaning of simultaneous is to solve by elimination

Multiply the equation 2 by -2

-2( 25r + 3s = 49)

-50r – 6s = -98

Then add the two equation to eliminate s, so the resulting equation is:

-45r =-45

r = 1

substitute r = 1 to equation 1

5(1) + 6s = 53

6s = 53 – 5

6s = 48

joja [24]

So..to make it easier you can jut multiply by 2 on both sides...

so you get 3y-2y=8+y..

which is equal to 0=8..but because they arent equal it means that there is no solution.
