Bro i did the same test [i picked c. for my answer]
(14 meter/sec) x (1 mile/1609.344 meter) x (3,600 sec/hour) =
(14 x 3600) / (1609.344) = <em>31.32 mile/hour </em>(rounded)
Answer:
8
Step-by-step explanation:
Since they intersect you can just solve for x and y
since y=-4x and y=x^2+2x+8, you can set -4x=x^2+2x+8
add 4x to both sides to make 0=x^2+6x+8
and factor out (x+4)(x+2)
so the solutions for x are -4 and -2
then insert the two values for x into the first equation
so y=-4(-4) and y=-4(-2)
so y=16 and y=8 when x=-4 and x=-2
so the smallest value for y in both equations is 8
Please give brainliest :)
