Suppose y varies directly with x and y =14 when x = -4 what is the value of y when x = -6

1 answer:

3 0

Y varies directlyas x means
x/y=k where k is constant
14/-4=k
-7/2=k

when x=-6
y/-6=-7/2
times both sides by -6
y=42/2
y=21
the value of y is 21

Correct question:

a sequence U1, U2,U3...... is defined by the relation $U_{n +1} = 2U_n +5$ . if U1 =2, find U2 and U3

Answer:

U2 = 9

U3 = 23

Step-by-step explanation:

Given sequence;

$U_{n +1} = 2U_n +5$

U1 = 2

U2 = ?

$U_{n +1} = 2U_n +5\\\\U_2 = 2(U_1) + 5\\\\U_2 = 2(2) + 5\\\\U_2 = 4 + 5\\\\U_2 = 9$

Solving for U3;

$U_3 = 2(U_2) + 5\\\\U_3 = 2(9) + 5\\\\U_3 = 18 + 5\\\\U_3 = 23$

To land on 0 the number would need to end with a .5 or .0 since that is the only way .0 can occur with counting down by.5( half)
