Answer:

first one is f(x)=-5

second one is f(x)=7

third one is x=-3

4th one is x=0

5th one is f(x)=1

6th one is x=-4

Step-by-step explanation:

first one. plug in x as -2:

f(x)=2*-2-1=-4-1=-5

second one is the same way:

f(x)=4*2-1=8-1=7

third one is a different one:

2x-1=-7

2x=-6

x=-3

4th one is the same way:

2x-1=-1

2x=0

x=0

5th way is the same thing as previous:

f(x)=2*1-1=2-1=1

Finally, the 6th one is the same thing as the 4th one:

2x-1=-9

2x=-8

x=-4

Answer:

Mandy will take 67.5 mins to complete the 15 km race.

Step-by-step explanation:

Given:

Mandy runs 4 km in 18 min

She plans to run in a 15 km race.

We need to find how much time required to run 15 km.

4 km =18 min

15 km = time required for 15 km race

By Using Unitary method we get,

Time required for 15 km = $\frac{18\times 15}{4}=67.5 mins$

Hence time required by Mandy to complete 15 km race is 67.5 mins.
