Question 1
The given system of equations is:

Equate the two equations:

Rewrite in standard form:




When we put x=0, in y=3x +6, we get:

One solution is (0,6)
When we put x=-2, into y=3x+6, we get:

Another solution is (-2,0)
The solutions are; (0,6) and (-2,0)
Question 2:
The function is

Let us put x=-x,

This gives:

We can observe that:

This is the property of an even function.
Question 3:
The given function is

The average rate of change of f(x) from x=a to x=b is given as:

This is the slope of the secant line connecting the two points on f(x)
From x=2 to x=6, the average rate of change

The average rate of change is 11
Answer:
3(x+8)
Step-by-step explanation:
In order to factor the expression completely, you need to find the greatest common factor of both numbers, which would be 3 because 3 fits in both numbers without leading to weird decimals or fractions.
3(x+8) is the answer.
<u>1.03*10^{6}>9.8*10^{5</u>
Answer:
4.01*10³<5*10^(-5)false
3.9*10^5<8.06*10^{-7}false
1.03*10^{6}>9.8*10^{5}true
7.8*10^{2}>2.1*10^{3}false
Answer: 64 days
Step-by-step explanation: 1/8 every day, so he has 1 bag per 8 days, 8 bags, so 8x8 = 64 days.
3-4 feet would be a good estimate I think
