Plug in x-2 for y
x + x - 2 = -10
2x = 12, x = 6
The value of x is 6
Answer:
a. The terms are;
40, 20 , 10
b. The function will be;
f(x) = f(x-1)/2
Step-by-step explanation:
Here, as we can see, the number of dots in a preceding term is twice the number of dots in the succeeding term
What we mean here is that as we progress, the number of dots in the last term is twice the number of dots in the next term
Firstly, let us fill in the terms written;
That’s ;
40,20,10
The function that determines or describes the pattern is;
Tn =1/2 * Tn-1
or simply put;
f(x) = f(x-1)/2

Answer: The equations are A= 600 + 125w and A = 1100 + 50w. Look into the steps for more information.
Step-by-step explanation:
Zypel's situation can be represented by the equation, A= 600 + 125w where A is the amount of money she will have after w weeks.
The same way we can represent Joshua's situation by the equation
A = 1100 + 50w where a is also the amount of money he will save after w weeks.
It says that there are 4 weeks in one month which means there will be 16 weeks in 4 months.
Now input 16 into the equations for w and solve for A.
A = 600 + 125(16)
A= 600 + 2000
A = 2600
So Zypel will save $2600 in a 4 months
A = 1100 + 50(16)
A= 1100 +800
A= 1900
So Zypel will save more than Joshua in four months.
10 liters of gas fill one tank.
x liters of gas fill x/10 tanks.
35 liters of gas fills 35/10=7/2 tanks
7/2 can also be written as 3.5 or the mixed number (3 and 1/2)
