The answer is 1 1/5
Hope this helps
2²-6x-56
this is unfactorable because there is no x on where the number is squared or the -56
Here are the steps
put it into y=mx+b 4y=-5x+20
to isolate y divide both sides by y=-5/4+5
to find the xi
xi is when y=0 so plug it in to the equation 4y=-5x+20 4(0)=-5x+20
0=-5x+20 subtract 20 from each side -20=-5x the negatives cancel out 20=5x
to isolate x divide each side by 5 x=20/5
20/5=4
Answers:
m=-5/4
yi=5
xi=4
I’m not sure but i think the answer is 1124.28 to 2 decimal places.
