ABCD~EFGH 3, x, 4.5, 140°, 50°, 110°, 2, 2.4 x =?​

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

most likely linear (proportionate)

step-by-step explanation:

as time increases heart rate increases
