Step-by-step explanation:
So, you have to get angle under 130° angle:
180°-130°= 50°
And you get X
x=180°-(113°+50°)
x=180°- 163°
x=17°
Answer:
red: x
blue: 2x+3
Step-by-step explanation:
let the number of red chips= x
let the number of blue chips= 2x+3
Answer:
X= -7 ± √17 / 16
x= - 0.7798...
Step-by-step explanation:
For this case we have a function of the form:

Where,
A: initial amount
b: decrease rate
x: time in days
Substituting values we have:

Therefore, the graph of the function is a decreasing exponential function in the first quadrant and that has an initial value of 40.
Answer:
graph of exponential function going from left to right in quadrant 1 through the point 0, 40 and approaching the x axis
