Answer:
The equation for the amount of tax (8%) T on an item that costs P dollars is:
T=0.08P
Step-by-step explanation:
X=25 and u would add 5x to both sides 6x=25+5x then u would multiply both sides by 0.25 making it 1.5x=6.25+1.25x
Answer:
(c) 4x - 7
Step-by-step explanation:
7x - 3x
= -4x
-5 -2
= -7
4x - 7
Answer: y = 3.5 x+ 43.8
Step-by-step explanation:
Here x represents the number of years after 1990
Thus, we get the table that is used to find the equation will be,
x 0 2 4 6 8
y 45 51 57 61 75
Let the equation that shows the above data,
y = b + a x ---------(1)


By the above table,




By substituting these values in the above value of a and b,
We get b = 43.8 and a = 3.5
Substitute this value in equation (1)
we get, the equation that shows the given data is,
y = 3.5 x + 43.8
⇒ Option (3) is correct.
