Answer;
x = 0.6 and x = -1.75
Step-by-step explanation:
80x2+92x−84=0
Use quadratic formula
x = (−b ±√(b2−4ac))/√2a
x = (-92 ± √(35344)) / 160
x = 95/160 and x = -280 / 160
x = 0.6 and x = -1.75
Answer:
Step-by-step explanation: The simplification calculator allows you to take a simple or complex expression and simplify and reduce the expression to it's simplest form.
(0, 2 ), (4,5)
to draw a graph of a straight line , we only require 2 points
select any 2 values for x, substitute them into the equation for the corresponding y- coordinates
x = 0 → y = 0+2 = 2 ⇒ (0, 2)
x = 4 → y = 3+2 = 5 ⇒ (4, 5)
Plot these 2 points and draw a straight line through them for graph
