Ответ:
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
Ответ:
Step 1: add what is inside the parenthesis
9 + 1.34 + 1 2 (5.24)
Step 2: multiply what is inside the parenthesis by 12.
9 + 1.34 + 62.88
Step 3: Add all the numbers
73.22
