Answer:
x=-0.544727
x=2.294727
Step-by-step explanation:
Given quadratic equation to solve:
To solve, use the quadratic formula
x= -b ± b² - 4ac / 2a
Substitute your values for a, b, & c and solve
x= -7 ± 7² - 4·(-4)·5 / 2·(-4)
x= -7 ± 49 - -80/-8
x= -7 ± 129/-8
Then, reduce the problem
x= -7/-8 ± 129/-8
x=-0.544727
x=2.294727
Answer:
- B) y = negative 4 x + three
Step-by-step explanation:
<u>Find the slope of the line that goes through (0, 8) and (2, 0):</u>
- m = (y₂ - y₁)/(x₂ - x₁)
- m = (0 - 8) / (2 - 0) = -8/2 = -4
Parallel lines have equal slopes.
<u>Looking at the choices we see only one of them has the slope of -4:</u>
We have: 5m 75cm = 5.75 m
So the length of each piece is : 
ok done. Thank to me :>
