Answer:
part A:d=5.4-3.1
Part B:t=4.9+3.1
Part C:If ted walks 5.4 kilometers,then david walks 2.3 kilometers,If david walks 4.9 kilometers,then ted walks 8 kilometers.
Y=mx+b
b represents your y-intercept
mx represents your slope
B. represents a dialation
K=y/x
k=68.75/5 (you can pick any number by multiplying x by 13.75)
k=13.75
hope this helps
Answer:
y = 12x + 8
Step-by-step explanation:
1. 3x - 1/4y = -2
Subtract 3x from both sides
2. -1/4y = -2 - 3x
The equation is in standard form.
3. -1/4y = -3x - 3
Multiply both sides by -4
4. Check photo for step 4
Divide by -1/4 = -0.25 undoes the multiplication -1/4 = -0.25
5. y = (-3x-2) / (-1/4)
Divide -2 - 3x by -1/4 = -0.25 by multiplying -2 - 3x by the reciprocal of -1/4 = -0.25
y = 12x + 8
