The numbers in the sequence decrease by 7 each step. Just subtracting.
THE answer is D :))))))))))
Answer:
Input of x when it is equal to (1,2,3,4,5) gave an output of 3, 9, 27,81 & 243 respectively.
Step-by-step explanation:
Step 1. Substitute for x (1,2,3,4,5) in the functions to solve for the output of y.
y=3^x
when x= 1
y=3¹ = 3
when x= 2
y=3² = 9
when x= 3
y=3³ = 27
when x= 4
y=3⁴ = 81
when x= 5
y=3 ^ 5 = 243.
Input of x when it is equal to (1,2,3,4,5) gave an output of 3, 9, 27,81 & 243 respectively.
Answer:
3 and -4
Step-by-step explanation:
this is simple but difficult
let the number be x and second number be y
3x + 2y=1
x-y/2=5
from the 2nd equation
x-y/2=5
x=5+y/2
substitute value for x into equation 1
3x + 2y=1
3(5+y/2) + 2y= 1
15 +3y/2 +2y=1
15 + 7y/2=1
7y/2= 1 - 15
7y/2=-14
cross multiply
7y= -28
y= -28/7
y= -4
therefore second number is -4
substitute value for y into 1st equation
3x + 2y=1
3x + 2(-4) = 1
3x - 8= 1
3x= 1+8
3x= 9
x= 9/3
x= 3
therefore first number is 3
therefore two numbers are;
3 and -4
