Answer:
w=5
Step-by-step explanation:
using the distributive property to simplify the equation
-4(w)+1(-4)=-24 so
-4w-4=-24 (adding 4 to both sides)
-4w==20 (divide by -4)
w=5
(0,15)(1,19)
slope = (19 - 15) / (1 - 0) = 4
y = mx + b
slope(m) = 4
(0,15)...x = 0 and y = 15
sub
15 = 4(0) + b
15 = b
y = 4x + 15....so ur rule is : F(s) = 4s + 15

Answer:
exponential. not linear functions because they change by equal differences not intervals.
Answer: 26 minutes
Step-by-step explanation:
Assume that the total time spent in the morning which includes getting dressed, eating breakfast, making her bed, and driving to work is x.
Time getting dressed = ¹/₃x
Eating breakfast = 10 mins
Making bed = 5 mins
¹/₃x + 10 + 5 = 35 ½
¹/₃x + 15 = 35 ½
¹/₃x = 35 ½ - 15
¹/₃x = 20 ½
x = 20 ½ / ¹/₃
= 61.5 minutes
Total morning routine is is 61.5 mins
Time taken to drive to work is;
= 61.5 - 35 ½
= 26 minutes
