Ok so there are 8 min of commercials and if each commercial is .25 minutes. what I did was 8 × 60 to get how many seconds there were. which = 480 and then I did .25 min × 60 and got 15 so I subtracted 15 from 480 and got 7.75
but it says how many commercials so you have to round to the full commercial and you get 8
so I think the answer is 8 or 7.75.
Answer:
K = 5m+y/x
Step-by-step explanation:
Let's solve for k.
y=kx+1m(2−7)
Step 1: Flip the equation.
kx−5m=y
Step 2: Add 5m to both sides.
kx−5m+5m=y+5m
kx=5m+y
Step 3: Divide both sides by x.
kx/x = 5m+y/x
Therefore, k = 5m+y/x
Use the substitution method for x
y= 4(-2)-1
y= -8-1
y= -9
Answer is y=-9
Answer:
21.96 ; 24.72
Step-by-step explanation:
Given that :
Give the equation:
A(t) = 700(1.03)^t
A.)
Average rate of change over the first 4 years ;
(t=0 to t=4)
At t = 0
A(0) = 700(1.03)^0 = 700
A(1) = 700(1.03)^1 = 721
A(2) = 700(1.03)^2 = 742.63
A(3) = 700(1.03)^3 = 764. 9089
A(4) = 700(1.03)^4 = 787.856167
[(721 - 700) + (742.63 - 721) + (764.9089 - 742.63) + (787.856167 - 764.9089)] / 4
= 87.856167 / 4
= 21.96404175
= 21.96
Over the 2nd 4 years :
A(4) = 700(1.03)^4 = 787.856167
A(5) = 700(1.03)^5 = 811.49185201
A(6) = 700(1.03)^6 = 835.8366075703
A(7) = 700(1.03)^7 = 860.911705797409
A(8) = 700(1.03)^8 = 886.73905697133127
[(811.49185201 - 787.856167) + (835.8366075703 - 811.49185201) + (860.911705797409 - 835.8366075703) + (886.73905697133127 - 860.911705797409)] / 4
= 98.88288997133127 / 4
= 24.72
Just replace the x in the question with -2, and the y with 2.
Therefore, you're doing ((-2)(2²))/7 which is -2 times 2 squared all over 7.
-2 × 2² = -8
-8/7 is your answer.
