I think your answer would be 4,000
Answer:
our inputs are 3 & 1/2
Step-by-step explanation:
the ? is the slope and the slope is equal to 1/2 so
?=1/2
the point slope formula is
(y-y1)=m(x-x1) (x1,y1)--> a point on the line m--> slope
so we chose (x1,y1) as (3,0)
when we plug that in we get
y-0=1/2(x-3)
so our inputs are 3 & 1/2
Simplifying
3[x + -1] = 12
Reorder the terms:
3[-1 + x] = 12
[-1 * 3 + x * 3] = 12
[-3 + 3x] = 12
Solving
-3 + 3x = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 3x = 12 + 3
Combine like terms: -3 + 3 = 0
0 + 3x = 12 + 3
3x = 12 + 3
Combine like terms: 12 + 3 = 15
3x = 15
Divide each side by '3'.
x = 5
Simplifying
x = 5
- 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.
