5 0

You can "plug in" the value for y from the top eq in the bottom one:

3(-2x+6) - x + 3 = 0

Simplify:

-6x + 18 - x + 3 = 0

-7x + 21 = 0

-7x = -21

x = 3

y = -2*3+6 = 0

In a basketball skills competition, Corson successfully made 5 of 7 shots and Charleigh made 3 of 5
xxTIMURxx [149]

Answer:

Corson had a better performance at the skills competition.

Step-by-step explanation:

In order to determine which player had a better performance at the skills competition, we need to find the percentage performance of both the players.

Therefore,

Corson's percentage performance

=\frac{5}{7}\times 100= 71.43%

Charleigh's percentage performance

=\frac{3}{5}\times 100= 60%

\because Corson's percentage performance > Charleigh's percentage performance

So, Corson had a better performance at the skills competition.

X+ 1/x =5 what is the value x²+1/x²?
irga5000 [103]
X+ 1/x= 5
⇒ (x+ 1/x)^2= 5^2
⇒ (x+ 1/x)^2= 25
⇒ x^2+ 2(x)(1/x)+ 1/x^2= 25
⇒ (x^2+ 1/x^2)+ 2*1= 25
⇒ x^2+ 1/x^2= 25 -2
⇒ x^2+ 1/x^2= 23

The final answer is 23~
