Answer:
Unknown
Step-by-step explanation:
Hi! so you didn't add the ordered pair options but I will do my best :) so if you see the ordered pair (0.7) that could definitely be a solution because using the slope intercept form equation you gave I know that's our y Intercept. the slope is 4/1 so moving up 4 and to the right 1 or down 4 and to the left 1 on a graph could show you more points! If you don't want to draw it you could use Desmos and just put this equation in or give me the ordered pairs and I will give you your answer!
hope this helps :)
I kept getting 900 i am sorry if that is incorrect
Answer:
B) -2.5
Step-by-step explanation:
2x^2 + 5x -3 = 0
(2x - 1)(x + 3) = 0
2x - 1 = 0; 2x = 1, so x = 1/2 = ROOT 1
x + 3 = 0, so x = -3 = ROOT 2
Now add the roots: -3 + 1/2 = - 2 1/2, so the answer is B.
Ok well check it out work out how long it took to hose 1/7 the of the lawn which is 2/5 hours. Times that by 7 to get the whole lawn: 7 x 2/5 = 2.8 hours hope that helps
