Answer:
18
Step-by-step explanation:
Do you see a pattern? Each time it decreased by 3. 33-3=30, 30-3=27, the pattern goes on, just do the same with the last shown number. 21-3=18
Answer:
y=1/5x-39/5
Step-by-step explanation:
y=mx+b (slope y intercept formula)
y=1/5x+b
take (-6,-9) and put in appropiate places
-9= -6/5+b
*multiply lhs and rhs by 5
-45= -6+5b
-45+6=5b
-39=5b
-5b=39
b=39/-5
y=1/5x-39/5
Answer:
y = 0.15x+77 is the equation linear connecting total cost y and miles driven x
Step-by-step explanation:
Given that the leasing company charged a flat rental fee for the week, plus a charge for each mile driven.
Let flat rental fee be c and cost per mile driven = m and miles driven = x
Total cost =y
Then y = mx+C is the linear equation.
to find m and c, we use the fact that y =110.30 when x = 222
i.e. 110.30 = c+222x
and similarly 99.05 = c+147x
Subtract to eliminate c
11.25 = 75 x
0.15 =x
Substitute in I equation
110.30 = c+222(0.15)
c = 77
y = 0.15x+77 is the equation linear connecting total cost y and miles driven x
