When x = 0 y = a(b)^x = a which is the y intercept
so as the y-intercept = 3 a must be = 3.
Answer:
D.
Step-by-step explanation:
The gragh crosses the y-axis at (0,-5), decreasing from x=-10 to x=-2 and remaining constant from x=-2 to x=10
The amount of times takes to assemble a simple puzzle is a quantitative variable.
Quantitative Variables are the variables whose values result from counting or measuring something.
A qualitative variable, also called a categorical variable, is a variable that isn't numerical.
Here given variable is amount of time takes to assemble a simple puzzle
The time is a quantitative variable
Hence, the amount of times takes to assemble a simple puzzle is a quantitative variable.

Answer:
x = 28
Step-by-step explanation:
ΔARP ≈ ΔCRD
42/x = 57/(10+x)
cross-multiply:
42(10+x) = 57x
420 + 42x = 57x
420 = 15x
28 = x
Answer:
x=3, multiplicity of 2
x=-5, multiplicity of 1
Step-by-step explanation:
f(x) = (x - 3)(x - 3)(x + 5)
Rewriting
f(x) = (x - 3)^2(x + 5)
Setting equal to zero
0 = (x - 3)^2(x + 5)
Using the zero product property
(x-3)^2 = 0 x+5 = 0
x-3 = 0 x= -5
x=3 x-5
Since x-3 was squared, the multiplicity is 2
