Answer:
7x + 3y = 44
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c (m is the slope and c the y- intercept )
Rearrange - 3x + 7y = 5 into this form by adding 3x to both sides
7y = 3x + 5 ( divide all terms by 7 )
y = 
x + 
← in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= - 
, thus
y = - x + c ← is the partial equation
To find c substitute (5, 3) into the partial equation
3 = - 
+ c ⇒ c = 3 + = 
y = - x + ← in slope- intercept form
Multiply through by 3
3y = - 7x + 44 ( add 7x to both sides )
7x + 3y = 44 ← in standard form
2x=84 is a one step equation so all u need to do is divided both sides by 2 so the variable can be by itself, so x=42
In 386750.36 years the Carbon - 14 will be 20 g in the substance
Step-by-step explanation:
Here A = 20 g
The given equation is,
A= 25e - 0.000124t
We need to find the value of t
20 = 25e - 0.000124t
20 - 25e = - 0.000124t
25e - 20 = 0.000124t
(25e - 20 ) / 0.000124 = t
t = (25e - 20) / 0.000124
t = (65.957 - 20) / 0.000124
t = 45.957 / 0.000124
t = 386750.36 years
