  • It is linear as the equation performs ax+by +c
  • y = 90.2x - 177670
  • number of student to enroll 2011 is 3722

Step-by-step explanation:

  • Linear is a straight line.
  • Quadratic is a square which generates parabola.
  • Quadratic formula is (ax)^2 + bx + c = 0.
  • Linear formula is ax+bx + c = 0
  • To  forecast time series data modelling can be used.
  • To form a linear equation y = mx + c.
  • After finding x is the required value , m is the intercept and C constant.
  • X axis have years and Y axis has the value.
  • to find number of students x is 90.2 * 2011 - 177670.
  • The result comes to 3722.
  • In Data analysis predictive modeling is the second phase.
  • It is important because it helps in associating to variables.

Answer:

1.) \frac{5}{4\\}

2.) \frac{4}{3}

3.) 1

4.) \frac{2}{3}

5.) \frac{9}{8}

6.) \frac{7}{8}

Step-by-step explanation:

The 2 steps for all of these is to get common denominators and then add and simplify.

1.) 3/4 + 1/2 (common denominator) 3/4 + 2/4 = 5/4

2.) 5/6 + 1/2 (common denominator) 5/6 + 3/6 = 4/3

3.) 3/6 + 1/2 (common denominator) 3/6 + 3/6 = 6/6 (simplify) = 1

4.) 1/6 + 4/8 (common denominator) 8/48 + 24/48 =  32/48 (simplify) = 2/3

5.) 7/8 + 1/4 (common denominator) 7/8 + 2/8 = 9/8

6.) 3/8 + 1/2 (common denominator) 3/8 + 4/8 = 7/8

the difference of two number is 28 if the larger number is three time of the smaller find the number​
Elza [17]

Set up an equation:

3x - x = 28

Simplify:

2x = 28

Divide both sides by 2

X = 14

3(14) = 42

The numbers are 42 and 14

Find the perimeter of a rectangle with a length of 6x+3 and a width of -2x-5.
blsea [12.9K]
The simple way of calculating a perimeter is to add all of the sides.
For a rectangle this would equal 2 x length + 2 x width
P = 2(6x + 3) + 2(-2x - 5)
= 12x + 6 - 4x - 10
= 8x - 4

At a higher level both the length and width must be greater than zero (= zero is a trivial rectangle)
6x + 3 > 0
6x > -3
x > -0.5

-2x - 5 > 0
2x + 5 < 0 (multiplying by -1 reverses the inequality)
2x < -5
x < -2.5

This rectangle cannot exist as x cannot be < -2.5 and > -0.5 at the same time!
