What is -2(4g-3)=30 I can't figure it out so I need so help
timofeeve [1]

Answer:

g =  - 3

Step-by-step explanation:

- 2(4g - 3) = 30

- 8g + 6 = 30

- 8g + 6 - 6 = 30 - 6

- 8g = 24

\frac{ - 8g}{ - 8}  =  \frac{24}{ - 8}

g =  - 3

Circle the rate that does not belong with the other three. Explain your reasoning.
gladu [14]
<span>500ft/1minute
</span> <span>The rate which deviates from the choices given is 500ft/1min
<span>Since, 60mi/hr and 88ft/s =1440mi/day
To illustrate this hypothesis we can solve and convert 60miles/hr
60 x 24 = 1440
hence, 60miles/hr = 1440miles/day

88ft/s
1. 88ft = 0.016667miles
2. 60 seconds = 1 minute </span></span> 3. 60 minutes = 1 hr 4. 24 hours = 1 day Hence, in conversion <span><span>
60 sec x 60 min x 24 hours = 86400s
0.016667 miles x 86400 sec  = 1440 mi/day
88ft/s = 1440miles/day</span> </span>

Determine the standard form of the equation of the line that passes through (-8, -6) and (-4, 9)
Darya [45]

Answer:

15/4 x-y=-24

Step-by-step explanation:

the standard form is ax+by=c

two points (x1,x2) , (y2,y1)

x1=-8       x2=-6

y1=-4        y2=9

find slope m: y2-y1/x2-x1

m=9-(-6)/-4-(-8)

m=15/4

find b: take any point(-8,-6)

y=mx+b

-6=15/4 (-8)+b

-6=-30+b

b=-6+30

b=24

y=15/4 x+24

standard form: y-15/4x=24

OR : 15/4 x-y=-24
