Mathematics
1 answer:
Usimov [2.4K]3 years ago
5 0

Answer:

A

Step-by-step explanation:

x^2 + x - 12

12 = 4*3,

We have -12 so 4 or 3 should be negative.

+ x , coefficient = +1 , so we have +4 - 3 = +1

(x+4)(x-3)

We can check:

(x+4)(x-3) = x^2 + 4x - 3x -12 = x^2 + x - 12

Answer:

The multiplicative rate of change is 3/4

Step-by-step explanation:

Here, we want to get the multiplicative rate of change

In this case, by dividing the succeeding term by the preceding term, we will get the multiplicative rate of change

mathematically, we have this as;

81/128 divided 27/32

= 81/128 * 32/27

= 3/4

Five times the difference of a number and two is seven more than that number
prisoha [69]
Answer: The number is: 4 ¼ ; or, write as 4.25 .
<span>_____________________________________________
</span>Explanation:
_______________
We set up the problem as:
_____________________________

5(x − 2) = 7+ x  ;  Solve for "x" (our "unknown number"; which is the answer).
____________________________________________________
Using the "distributive property of multiplication" :
____________________________________________________
a*(b + c) = ab + ac ; AND:

a* (b − c) = ab − ac ; 
_____________________________________________________
Let us take the "left-hand side" of our equation and expand it:
_______________________________________
5(x − 2) = (5*x) − (5*2) = 5x − 10 ;
_________________________________________
and rewrite the equation; substitute our "expanded value" for the "left-hand side";
________________________________
→ 5(x − 2) = 7+ x ;  ↔ 5x − 10 = 7+ x ;
____________________________________
Now, subtract "x" from EACH SIDE of the equation; & add "10" to EACH SIDE of the equation;
________________________________________________
 → 5x − 10 − x + 10 = 7+ x − x + 10 ; 
 _______________________________________________
 → to get:  4x = 17 ;  
________________________________________________
  → Now, divide EACH side of the equation by "4"; to isolate "x" on one side of the equation; and to solve for "x" (our answer);
________________________________________
 → 4x / 4 = 17 / 4; 
__________________________
 → x = 17/4  = 17 ÷ 4 = 4 ¼ ; or, write as 4.25 .
_________________________________________
→ Answer: The number is: 4 ¼ ; or, write as 4.25 .
_____________________________________________
→Let us check our answer: 
_____________________________________________
"Five times the difference of a number and 2"  ;
_____________________________________________
 → 5* (x − 2) = 5 * (4.25 − 2) = 5 * (2.25) = 11.25 ;

→ Is "11.25" ,  SEVEN MORE THAN 4.25??
_________________________________________
  → 11.25  −  4.25 =?? 7 ???  Yes!
