Sergeu [11.5K]

Answer:

a < -1

Step-by-step explanation:

Okay, so we are given this equation:

t(x) = ax^5 + 2

Lets plug in -2 as x and see what happens.. t(x) can be 66..

a * (-2)^{5}  + 2 = 66

-32a + 2 = 66

-32a = 64

a = -2

A is less than -1,

a < -1

Tyler can shovel the driveway in 2 hours Dakota can complete the job in 90 minutes if they work together how long will it take
topjm [15]
One JOB = 1  and 2 hours = 120 min

Tyler Rate per minute: 1/120 (in 1 minute he performes 1/120 of the job)
Dakota<span> Rate per minute: 1/90 (in 1 minute he performes 1/90 of the job)

Tyler's + Dakota's rate per 1 minute = 1/120 + 1/90  = 7/360 (Job/minutes)

7/360 of the job was performed in 1 minute
</span>a complete JOB =1 to be performed in x minutes (Rule of three)

x = 1x1/(7/360) that equals to 360/7 and x (time of both) = 51 min 42
