F(x) = x^2 - 3x - 8
f(-2) = (-2)^2 - 3 (-2) - 8
f(-2) = 4 - 3 (-2) - 8
f(-2) = 4 + 6 - 8
f(-2) = 10 - 8
f(-2) = 2 ✅

A women made a deposit of $196.If her deposit considered of 60 bills, some of them one-dollar bills and the rest being five-doll
raketka [301]
Answer: 26 pieces of $1 bill and 34 pieces of $5 bill

Total Deposit = $196
Total Bills = 60 pieces
Value of $1 = $1
Value of $5 = $5

Lets assume all the 60 pieces were $1 bill.
The total deposit will be 60 x $1 = $60

But we know that the total deposit is $196. So the extra value must have come from the $5. 

$196 - $60 = $136
There is still an outstanding amount of $136 not accounted for.

$5 - $1 = $4
The difference in the two bills is $4

Now we can find out the number of $5 bill by dividing the extra $136 by 4:
136 ÷ 4 = 34 pieces

There are 34 pieces of $5 bill.

Since there are 34 pieces of $5, the rest must be the $1 bill
60 - 34 = 26

There are 26 pieces of $1 bill.

Answer: 26 pieces of $1 bill and 34 pieces of $5 bill.

Find the zero of the function f (x) = -2x +2.
Zielflug [23.3K]

Answer:0 = 3x - 21

Step-by-step explanation:

From this given function we can take an  

x

common from its expression

i.e  

x

2

−

6

x

 

=

x

(

x

−

6

)

As we know that the product of two numbers is zero,when either one of them is zero

then in the above expression that we just factorised

the function can be zero when either  

x

=

0

or when  

x

=

6

i.e when  

x

=

0

,  

0

(

0

−

6

)

=

0

 

when  

x

=

6

,  

6

(

6

−

6

)

 

=

6

(

0

)

Finally, our prize of all that math, the zeroes of the function are  

0

and  

6

these numbers are called the zeroes of the function because when you put these values in  

x

the function gives zero.

Hye Sun has a modern coffee table whose top is a triangle with the following side legngths: 8 feet , 3 feet, and 5 feet. Is Hye
ale4655 [162]
8 feet is the longest side so it would be the hypotenuse. Use the Pythagorean formula to check.
a^2 + b^2 = c^2
3^2+5^2 = 8^2
9 + 25 = 64
34 = 64
This is obviously not true si it is not a right triangle.
