Solve this linear equation for p:<br> 2.6(5.5p – 12.4) = 127.92
Ymorist [56]
HI :)
First we must distribute the 2.6 to everything inside the () 

The new equation would then be
14.3p-32.24 = 127.92

Then you would add a -32.24 to each side of the equal sign, so that the 32.34 would become a zero pair on the right side of the equal sign and cancel. 

The new equation would then be
14.3p = 160.16

Then you divide each side of the = by 14.3, that way the p becomes isolated.
14.3p/14.3 = 160.16/14.3

Then you're left with 
p = 11.2

Hope this helped :)

What is the value of f(x) = 2 • 2^x for f(–2)? Will Give brainliest answer!!!
Sedbober [7]
For f(-2), x will equal -2.

Plug the x-value into the equation:

2 \times 2^{-2}

A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator. 
Solve 2^(-2):

2^{-2} =  \frac{1}{2^{2}} =  \frac{1}{4}

Solve the problem:

2 \times \frac{1}{4} = \frac{1}{2}

f(-2) will equal 1/2.

( 6 − √ 100 − 6 ⋅ 6 ) 3 − 9 ÷ 3
sergij07 [2.7K]

Answer:

(6 - √ 100 - 6 * 6) 3 - 9 ÷ 3 = -64003/1 = -64003

Step-by-step explanation:

1.Square root: sqrt(100) = √ 100 = 10

2.Subtract: 6 - the result of step No. 1 = 6 - 10 = -4

3.Multiple: 6 * 6 = 36

4.Subtract: the result of step No. 2 - the result of step No. 3 = -4 - 36 = -40

5.Exponentiation: the result of step No. 4 ^ 3 = (-40) ^ 3 = -64000

6.Divide: 9 / 3 = 3

7.Subtract: the result of step No. 5 - the result of step No. 6 = -64000 - 3 = -64003
