Y'all can you answer these? 8th grade algebra 1-10 Q's??

This is 8th grade? I learned this in 7th grade

Step-by-step explanation:

1. Slope= 3/4x (MAKE SURE TO PUT THE X) Y intercept = +7 (MAKE SURE YOU PUT A + IF IT IS POSITIVE AND - IF NEGATIVE

2. Slope = 5x  Y intercept = 8 (I think this was a trick question?)

3. Slope = -2x Y intercept = 0 (So just keep it empty or say 0 if your teacher is like that)

4. Slope = x Y intercept = +12

I can't see the full question so sadly I can't help with the otherones

step-by-step explanation:

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:  

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497

i think u have 12 apples sorry again i don't really know if it correct i'm just tryna hrlp people out.
