Oh my didn’t answer of why equals 61X equals 2/3 find XY equals 12 on you just multiplied by three and you’ll get the
Set them up to equal each other
-7x + 2 = 9x - 14
16 = 2x
x= 8
plug in the x value into any of the two y equations
y= 9 (8) - 14
y=58
points (8, 58)
The correct answer is: [A]: " 4x³ + x² − 11x + 15 " .

<u>Note</u>:
_______________________________________________________
(6x³ − 4x + 5) − (2x³ − x² + 7x − 10) ;
= (6x³ − 4x + 5) − 1(2x³ − x² + 7x − 10) ;
_________________________________________
Examine the following portion of the expression:
_________________________________________
" − 1(2x³ − x² + 7x − 10) " ;
= (-1 * 2x³) − (-1 * x²) + (-1 * 7x) − (-1 * 10) ;
= (-2x³) − (-1x²) + (-7x) − (-10) ;
= (-2x³) + 1x² − 7x + 10 ;
= " − 2x³ + 1x² − 7x + 10 " ;
Now, bring down the other part:
6x³ − 4x + 5 − 2x³ + 1x² − 7x + 10 ;
Combine the "like terms" :
6x³ − 2x³ = + 4x³ ;
− 4x − 7x = − 11x ;
+ 5 + 10 = + 15 ;
and bring down the:
+ 1x² ( which equals: " x² ") ;

And rewrite:

→ " 4x³ + x² − 11x + 15 " ;
→ which is: Answer choice: [A]: " 4x³ + x² − 11x + 15 " .

Answer:
More Than
Step-by-step explanation:
According to the given statement:
This year the club earned $20 more than twice what it earned last year. Let x represent the amount raised last year.
The two words in this problem which tell us about the operation are "More Than"
This year club earned $20 more than than twice it earned last year. This means, to find the earnings of this year, double the earnings of previous year and add 20 to them.
Since, x represents the earnings of last year, we can represent the earnings of this year as:
Twice of x + 20
2x + 20
