Answer:
a = 1
Step-by-step explanation:
Given the point (a, 3) is on the line: 5x + y = 8.
Any point on the line satisfies the equation.
So, (a, 3) should satisfy the equation 5x + y = 8
Substituting x = a and y = 3, we get:
5(a) + 3 = 8

⇒ a = 1
Therefore, (1, 3) is the point on the line.
Answer:
x=32
Step-by-step explanation:
i think you divide the 72 by 9 to find the answer that you times the 4 by. i got 8, so 8x4=32
Answer:
2
Step-by-step explanation:
Using the rule of logarithms
x = n ⇒ x = 
let
8 = n ⇒ 8 =
, that is
2³ =
( equate exponents )
n = 3
and let
(
) = n ⇒
=
, that is
=
( equate exponents )
n = - 1
then
8 +
(
)
= 3 + (- 1)
= 3 - 1
= 2
