Answer: 49x
Step-by-step explanation:
first, i rewrite the equation, removed the parentheses, and multiplied it all out.
(-5-4)x x (-5) + 7x - 3x
then, i calculated it.
-9x x (-5) + 7x - 3x
then, i multiplied and calculated again.
45x + 7x - 3x = 49x
Yep !! That’s cool I never knew :0
Answer: The formula for exponential growth is y = a(1 + r)^x, and the formula for exponential decay is y = a(1 - r)^x, with r being the rate of growth/decay. :)
Answer:
Step-by-step explanation:
One of the most important things to understand about lines is the definition of slope. Slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate slope by dividing the change in the y-value between two points over the change in the x-value.
Wrong because you need to add the -2 to the 8.... I hope this helps
