Answer:

25)In order to bring this inequality to graphable form, we need to move all the terms to the left side.In my example, term -144, will be moved to the left side.

Notice that a term changes sign when it 'moves' from one side of the inequality to the other. so it will be written as 12c+144≤0 and ur answer will be

c ≤ -12

27) term 3/5, will be moved to the left side. so it will be written like this 6b+(-3/5) ≥ 3/5 + (-3/5). then it will be written as 5(6b) + (-3)/5 ≥ 3/5 - 3/5, and ur answer will be

b ≥ 1/10

29) In order to factor an integer, we need to repeatedly divide it by the ascending sequence of primes (2, 3, 5...).The number of times that each prime 'goes into' the original integer becomes its exponent in the final result.     Prime number 2 goes into 8 three times. So it will be written like this, b/8 + 2 ≤  -2 + 2, and then b/2^3 + 2 ≤ 0 and ur answer will be

b ≤ -16

31) We need to get rid of all the denominators in this inequality. This can be achieved by multiplying both the left and the right side by the Least Common Denominator. In my example, the LCD is equal to 2 x 3. So it will be written like this, 3 < 2 (-r), and then 3 < -2r and ur answer will be, rin(-\infinity ,-3/2)

the perimeter of a rectangle brownie pan is 50 Inches. the lenght of the pan is 5 less than twice the width. write a system of e
Serga [27]

Answer: The system of equation is,

2 ( x + y ) = 50

x = 2 y - 5

Step-by-step explanation:

Let x represents the length of the rectangular brownie and y represents the width of the rectangular brownie.

Thus, the perimeter of the brownie = 2 ( x + y )

But, According to the question,

Perimeter of the brownie = 50,

2 ( x + y ) = 50

The length of the brownie is 5 less than twice the width,

That is, x = 2 y - 5

Thus, the required system of equation is,

2 ( x + y ) = 50 , x = 2 y - 5

An airplane is traveling due east with a velocity of 583 miles per hour. The wind blows at 75 miles per hour at an angle of S58°
ASHA 777 [7]

Answer:

  D. 647.8 miles per hour; S86.5°E

Step-by-step explanation:

We assume the wind direction is supposed to be S58°E. Then the bearing of the plane measured clockwise from north is 90°, and the direction the wind is blowing toward has a bearing of 122°. The resultant speed and direction is the sum of the two vectors, which is easily found using a suitable calculator:

  583∠90° + 75∠122° = 647.8∠93.5°

The bearing of 93.5° translates to the direction S86.5°E.

_____

An angle east of south is subtracted from 180° (south) to find the equivalent bearing.
