Answer:
y = 20*4^x
Step-by-step explanation:
to find the value of the constants a and b, we just need to use the points given in the equation and solve the system of equations:
point (0,20): x = 0 and y = 20:
20 = a*b^0 = a*1 = a
a = 20
point (2,320): x = 2 and y = 320
320 = 20 * b^2
b^2 = 16
|b| = 4
b = 4 or b = -4
So we have two exponencial equations that pass through these points:
y = 20*4^x and y = 20*(-4)^x
As the questions asks for just one equation, we can answer y = 20*4^x
Y=20+35x because the 20 is a 1 time thing and 35x because 35 is charged each month
The answer is 5÷90+8 and that's the answer does the answer
Answer:
-1/4
Step-by-step explanation:
-3/8 - 7/8= 4/8=1/2
Answer: C: 2/5
Step-by-step explanation:
because there is 10 tiles total in two bags with 5 tiles each
each bag has two vowels
so part over whole means 2/5
