The answer to this is letter C: <em>This equation is an example of converting by using proportion.</em> The proportion used here is the measurement of something in inches to the measurement of something in ft. The ratio would always be constant, hence, the equality sign.
Answer:
Step-by-step explanation:
There are currently 68 million cars in a certain country, increasingly by 1.8% annually. How many years will it take until this country has 81 million cars? Answer by ... A general equation which can be used for exponential growth (or decay) is: ... years, etc.) "A" is the amount after t units of time have passed.
#1
the answer would be C.) y = -2x + 4
here is why:
start with y = mx +b
imput the slope and the coordinates:
-8 = -2 x (6) + b
then solve for b
-8 = -2 x (6) + b
-8 = -12 + b
b = 4
so then the equation would be
y = -2x + 4
#2
y - 3 = 2 ( x - 7)
y - 3 = 2x - 14
y = 2x - 11
because none of the answers are in standard y=mx+b form I would say that the answer would be none.
