Hi!
Slope intercept form is in the form y=mx+b
m is the slope, and that is given so we can plug that into the equation
y = -5x + b
We are also given the y-intercept (0,2) and we can plug that into the equation as well, to find b
2 = 5(0) + b
2 = b
So now that we know both m and b, plug only those two into the equation.
y = -5x + 2
That is your equation
It could maybe be 4 ,6. i am not pretty sure if this answer is correct or incorrect but i am just trying.
Answer:
Step-by-step explanation:
g(x) = (5/8)^x is an exponential function. Because 5/8 is less than 1, this function decreases constantly. You should start with "easy" values of x, such as 0, 1, 1/2, and calculate the corresponding y-values.
x y = (5/8)^x Plot these points:
0 1 (0, 1)
1 5/8 (1, 5/8)
2 25/64 (2, 25/64)
10 0.009 (10, 0.009
-1 1.6 (-1, 1.6)
Observe that the y-intercept is (-1, 1.6), and that as x increases, the y values decrease. As x grows larger and larger, the curve of the graph approaches the x-axis. We call that axis the "horizontal asymptote).
System of Equations:
let these two numbers be x and y
x+y = 82
x-y = 29
If you add the two equations you can eliminate y.
2x = 111
x= 55.5
Plug x back into one of the two equations. So the two numbers are 55.5 and 26.5.
