Determine 93% of 108. Round your answer to the nearest tenth.
c. y = 1/4 x + 5
step-by-step explanation:
first, put the equation of the line on the graph into slope-intercept form
(y = mx + b): y = -4x + 8
second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )
original slope: m = -4 perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)
new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
5=812a+9+3
step 1: simplify both sides of the equation.
5=812a+9+3
5=(812a)+(9+3)(combine like terms)
5=812a+12
5=812a+12
step 2: flip the equation.
812a+12=5
step 3: subtract 12 from both sides.
812a+12−12=5−12
812a=−7
step 4: divide both sides by 812.
812a /812 = -7/812
a= -1/116
so the answer is
a= -1/116
