Answer:
B
Step-by-step explanation:
The exponential function has the form 
where a is the starting value or y-intercept. B is the rate of change and x is the variable typically time. In this situation, 
has starting value 4, rate 3 and a -x.
Normally an exponential curve glides left to right growing steeper as it goes. But a -x flips this behavior. The curve starts very steep then gradually slows down. This means only graphs B or D are options. Since only graph B of these two has a y-intercept at 4, graph B is the solution.

The triangle could be isosceles or scalene. It cannot be equilateral since all angles in that triangle would be 60 degrees. This prevents two sides from being perpendicular. Hope this helps!
Answer:
Step-by-step explanation:
3(10 – 4x) + 6 = 12
first you need to use the distributive property
30 – 12x + 6 = 12
then subtract 6 from each side
30 – 12x = 6
then subtract 30 from each side
– 12x = -24
divide both sides by negative 12
x = 2
Answer:
100
Step-by-step explanation:
Since l and r Parrell lines that means the measure of 4 is 80 since there vertical angles. And then 1 and 4 needs to be supplementary which means the two angles combined equals 180. so 180-80=100
so 1s angle measure is 100
