Hello:
2x+3y=8
y =(-2/3)x+8/3 (the slope is : (-2/3) )
<span>an equation of the line through (-1,4) and perpendicular to 2x+3y=8</span>
<span> is : y = ax+b
the slope is a : a×(-2/3) = -1......(
perpendicular to a line with a slope of -2/3)
a = 3/2 y=(3/2)x+b
the line that passes through (-1, 4) :4 =
(3/2)(-1)+b
b =11/2
the equation is : y = (3/2)x+11/2</span>
The cost of labor per hour is $55, and Savannah spent a total of $441.50.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represents the cost of labor per hour, hence if the total was $441.50, hence:
441.50 = 4.5x + 194
x = 55
The cost of labor per hour is $55, and Savannah spent a total of $441.50.
