Rewrite each problem so that x appears on only one side
Vlad1618 [11]

Answer:

x = -5/21

Step-by-step explanation:

Step 1: Write equation

2(12x - 1) = (21x - 49)/7

Step 2: Solve for <em>x</em>

  1. Multiply both sides by 7: 14(12x - 1) = 21x - 49
  2. Distribute 14: 168x - 14 = 21x - 49
  3. Subtract 21x on both sides: 147x - 14 = -49
  4. Add 14 to both sides: 147x = -35
  5. Divide both sides by 147: x = -5/21

Outside temperature over a day can be modeled as a sinusoidal function. Suppose you know the temperature is 45 degrees at midnig
Paraphin [41]

Answer:

D = 9sin(2π(t + a)/24) + 45

Step-by-step explanation:

Let's find the average temperature;

(54 + 36)/2 = 45°

Amplitude = 54 - 45 = 9

From the wave equation, we can write the temperature as;

D = 9sin(2π(t + a)/24) + 45

Where;

D is the temperature

t is the time in hours after midnight

a is a "phase" that is used to set the time at which temperature(D) occurs

1. Find f(-2) if : *<br> f (x) = 4 |x – 4| + 2<br>-20 <br> 28<br> 32 <br> 26 ​
Mandarinka [93]

Answer:   34

f(-2) means inserting 'x = -2' into the equation.

x = -2

4*|-2 -4| +2

= 4*|-8| + 2

= 4*8 + 2

= 32 + 2

= 34
