F(x)=1-x² and g(x)=√(11-4x)

(g+f)(2)=>

1-(2)²+√(11-4(2))

=√3-3

(f/g)(-1)

(1-(-1)²)/(√(11-4(-1))

=0

(g-f)(-1)

√(11-4*-1)-(1-(-1)²

=√15

(g×f)(2)

1-(2)²×√(11-4(2))

-3√3

lukranit [14]

Answer:

The answer is "8".

Step-by-step explanation:

Let the number are a, b, c then value is as follows:

a= 3

b= 5

c= 7

The addition of equation ⇒ a+b+c =15....................(i)

multiply by the value ⇒ 3a + 5b + 7c = 75 ...............(ii)

let b= 15-a-c which subtract from equation (ii)

equation:

⇒ 3a + 5b + 7c = 75

⇒ 3a + 5(15-a-c) + 7c = 75

⇒ 3a +75-5a-5c+7c = 75

⇒ 3a -5a-5c+7c = 75-75

⇒ -2a + 2c = 0

⇒ 2(c-a) = 0

⇒ (c-a) = 0

⇒ c=a

if we put value in between 0 to 7 from it satisfies the two equations, with c=a and b = 15 - a - c. So, the correct answer is 8.

Angelique had 20 tokens to use for games at the arcade. She lost some of them. Her dad tripled the tokens she had left. Angeliqu

alexandr402 [8]

Answer: Both the expressions are exactly same . Both are representing the number of tokens she has now.

Step-by-step explanation:

Given: The total number of tokens Angelique has= 20

Since, she lost some of them, let the number of lost tokens be t.

Then, The remaining tokens she has = 20-t

Then her father triples the tokens she has.

now, the number of token she has= $3(20-t)$ ....>Angelique's expression

By using distributive property,

The number of token she has= $3\times20-3t$

⇒The number of token she has= $60-3t$ ...> Dante's expressions

Hence, both are the same expressions. Both are representing the number of tokens she has now.

Carrie spent 1 /4 of her allowance on a shirt, 1 /3 of her allowance on a skirt, and $8 on a belt. If she spent $22 in all,

charle [14.2K]

Hi There!

Answer:

$24

Step-by-step explanation:

= 1/4 + 1/3

= 3/12 + 4/12

= 7/12

7/12a + 8 = 22

Subtract 8 to both sides of the equation.

7/12a + 8 - 8 = 22 - 8

Simplify

7/12a = 14

Switch

a = 12/7 * 14

Simplify

a = $24

Hope This Helps :)
