Answer:

f(x)=7x+4


When x=-8

f(-8)=7·(-8)+4=-56+4=-52


When x=3

f(3)=7·3+4=21+4=25


When f(x)=67, then :

7x+4=67

7x=63

x=9

Simplify (3a^4-2a^2+5a-10)-(2a^4+4a^2+5a-2
sammy [17]
<span>3a4-2a2+5a-10)-(2a4+4a2+5a-2) 
remove first set of parentheses:
 
apply "-" sign to second parentheses (distributive prop):
 
the - of a - becomes a + :
 
combine like terms:
 

Factor out the variables that are alike:

{(1)a^4 + (-6)a^2 + 0a + (-8)}}} 
0a is just 0, makea the "a" term go away:
 
can try to factor as squares, but it doesn't work out:
8 = (-4) x (+2) product factors cannot add to make 6. </span>

Prove that the value of the expression (2^10+2^8)(2^5-2^3) is divisible by 60
bearhunter [10]

Let's simplify it, because if we do, we can find the value and then deduce whether it is divisible by 60.

2^10 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2

2^10 = 1,024

2^8 = 256

2^5 = 32

2^3 = 8

Substitute the expressions in the equation for their values...

(1,024+256)(32-8)

Simplify...

(1,280)(24)

Simplify...

30,720

Now, divide it by 60...

512 * 60 = 30,720

512*60=(2^10+2^8)(2^5-2^3)

On a baseball team, there are infielders and outfielders. Some players are great hitters, and some players are not great hitters
inysia [295]

Answer: c. P(I \text{ or }\overline{H})

Step-by-step explanation:

Notation to show "not an event E" : \overline{E}

Given:  I = the event that a player in an infielder.

H = the event that a player is a great hitter.

= the event that a player is not a great hitter.

The correct symbol for the probability that a player is an infielder or is not a great hitter : P(I \text{ or }\overline{H})

hence, the correct option is  c. P(I \text{ or }\overline{H})
