Answer:
help with what? what is your q u e s t i o n
Step-by-step explanation:
Answer: x = 1
x =(-3-√-15)/4=(-3-i√ 15 )/4= -0.7500-0.9682i
x =(-3+√-15)/4=(-3+i√ 15 )/4= -0.7500+0.9682i
x2 = 0

1. Two integers with the same signs
Once 2 integers has the same sign, then just add the numbers.
For example</span>
<span>1. 1+1 = 2 </span>
<span>2. 2 + 5 = 7 </span><span>
2. Two integers with different signs
<span>When 2 integers has different sign, then find the difference
For example
1. 1-1 =0</span></span>
<span>2. 2 – 5 = -3 </span><span>
3. Two integers that vary in sign
<span>When 2 integers vary in sign, then it will depend who which number carries the largest value

1. </span>-3 + 2 = -1</span>

The average rate of change of a function f(x) in an interval, a < x < b is given by

Given q(x) = (x + 3)^2
1.) The average rate of change of q(x) in the interval -6 ≤ x ≤ -4 is given by

2.) The average rate of change of q(x) in the interval -3 ≤ x ≤ 0 is given by

3.) The average rate of change of q(x) in the interval -6 ≤ x ≤ -3 is given by

4.) The average rate of change of q(x) in the interval -3 ≤ x ≤ -2 is given by

5.) The average rate of change of q(x) in the interval -4 ≤ x ≤ -3 is given by

6.) The average rate of change of q(x) in the interval -6 ≤ x ≤ 0 is given by
The equation of proportional relationship is of the form:

where m is the slope.
Drawing it is fairly easy, you start from the origin (0, 0) and you draw a diagonal staight line. The inclination of the line depends on the value of m. See picture attached.
