| Y | 4 | 8 |16|20| 40 |
Answer:
b
Step-by-step explanation:
Y is three times the value of x , It can be said that y is directly proportional to Y .
Direct proportion is when an increase in the independent variable causes an increase in the dependent variable.
the equation for direct proportion is :
y = bx
y = dependent variable
b = constant
x = independent variable
Answer:
45
Step-by-step explanation:
9, 13, 17, 21, 25
We are adding 4 each time
9+4 = 13
13+4 =17
17+4 = 21
The common difference =4
a1 = 9
The formula is
an = a1+d(n-1) where n is the term number
an = 9+4(n-1)
We want the 10th term
a10 = 9+4(10-1)
= 9+4(9)
= 9+36
= 45
Answer:
2^5 + 4^3 – 6x + 3
Step-by-step explanation:
Order the numbers by decreasing exponents. Start with the 2^5, since it has an exponent of 5. Next is the 4^3 since it has an exponent of 3. After that is -6x since it has an exponent of 1. 3 is last because it has an exponent of 1 and it has no variables attached.
