Answer:
The rate of change in the table is 78 students per year
Step-by-step explanation:
Here, we want to get the rate of change of the function
Mathematically, we can get this by using the formula;
m = (y2-y1)/(x2-x1)
(x1,y1) and (x2,y2) are points we are to select from the table
Let us select the point (4,704) and (17,1718) from the table
The slope is thus;
m = (1718-704)/(17-4) = 78 students per year
Answer:
2 ( 4x² + 3xy - 2 )
Step-by-step explanation:
( 5x² + 4xy - 7 ) + ( 3x² + 2xy + 3 )
5x² + 4xy - 7 + 3x² + 2xy + 3
Combine like terms.
5x² + 3x² + 4xy + 2xy - 7 + 3
8x² + 6xy - 4
Factorize the answer.
2 ( 4x² + 3xy - 2 )
Answer:
Exact form: x = + 7 sqaureroot 2
Decimal Form: x = 9.89
Y – 3x = 7
y -3x +3x = 7+3x
y = 7+3x
21 + 9x = 3y
21 + 9x = 3(7+3x)
21 + 9x = 21 + 9x
The answer is B.There are an infinite number of solutions.
