Answer:

the first, second, third, fourth, and fifth, answers apply to this graph

Step-by-step explanation:

The graph is a constant line from 7-10 minutes (a 3 minute break)

After the first five minutes on the graph there is a great increase in his speed. (he covered more of the race in that time up until the 7th minute)

It is true he only had one mile left - this can be shown by his graph stopping at the 4th mile on the 15th minute

there is a slow but gradual increase in his speed as he covered more of the race in the first five minutes

At the 7th minute mark he is at mile 3 - there are 4 miles to the race

_______________________________

The last one is NOT true because he has another increase in the graph at the 11th minute mark.

A=4,b=-2,C=5 d=-6 , e =-1 5 ed-3cb +4ba-2ea​
Alecsey [184]

Answer:

208

Step-by-step explanation:

{ed}-{3cb}+{4ba}-{2ea} = {(-15)*(-6)} - {3*5*(-2)} + {4*(-2)*4} - {2*(-15)*4}

={90} - {15*(-2)} + {16*(-2)} - {8*(-15)}

= {90} - {-30} + {-32} - {-120}

= 90 (--)30 (+-) 32 (--) 120

= 90 + 30 - 32 + 120

= 120 - 32 + 120

= 88 + 120

= 208
