The sum of the rational expression is
X=4
Answer:
y = 2
Step-by-step explanation:
For the exponential function in the form
y = a
Use ordered pairs from the table to find a and b
Using (0, 2 ), then
2 = a ( = 1 ) , thus
a = 2, so
y = 2
Using (1, 6 ) , then
6 = 2b ( divide both sides by 2 )
b = 3
Thus the exponential function is
y = 2
Answer:
7b-c²
Step-by-step explanation:
7times b is 7b reduced by the square of c means minus c²
-3x + 7y = -16 . . . (1)
-9x + 5y = 16 . . . .(2)
(1) x 3 => -9x + 21y = -48 . . . (3)
(2) - (3) => -16y = 64 . . . (4)
Required equivalent system of equations is
-9x + 5y = 16
-16y = 64
