Answer:
The value of x in terms of b is:
The value of x when b is 3 is: x = -1
Step-by-step explanation:
We are given the function:
First we need to find
The value of x in terms of b
We need to find value of x
Multiply -2 with terms inside the bracket
Subtract 10 from both sides
Divide both sides by -2b
So, The value of x in terms of b is:
The value of x when b is 3
We have the equation for the value of x in terms of b:
Put b = 3
So, The value of x when b is 3 is: x = -1
The equation of the line is y = 0.8x - 1.4 if the slope of the line is 0.8 and line passes through coordinates (-2,-3)
<h3>What is a straight line?</h3>A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
The slope m = 0.8
The line passing through coordinates (-2,-3)
y = mx + c
y = 0.8x + c
Plug the point in the equation.
-3 = 0.8(-2) + c
c = -1.4
y = 0.8x - 1.4
Thus, the equation of the line is y = 0.8x - 1.4 if the slope of the line is 0.8 and line passes through coordinates (-2,-3)
