Solve for x: 6 x2 + 2x - 3 2 = 0

Mathematics

1 answer:

8 0

I think the answer is 10 because:

6x2=12

12+2x-32=0

make the like terms together = 12-32+2x=0

= -20+2x=0

again make the like terms together = 2x=0+20 [sign changes when it goes to the other side]

so, 2x=20

x=20/2 [ multiplication will change into division when it goes to the other side]

therefore x=10

Suppose that x and y vary inversely, and x = 7 and y=11. Which function models the inverse variation?Answers:Y=1.57xY=77/xY=4/xY

sdas [7]

Answer:

Y=77/x

Explanation:

Y varies inversely with x meaning

$y\propto\frac{1}{x}$

adding a proportionality constant gives

$y\propto\frac{k}{x}$

Now, we are told that y = 11 and x = 7; therefore, the above gives

$11=\frac{k}{7}$

Solving for k gives

$k=77$

Therefore, the function that models the inverse variation is

$y=\frac{77}{x}$

which is our answer!
