I believe you should do as much work as you can on each of these problems and only then ask for help. You'll almost always learn more by becoming involved in the thinking and problem solving you encounter here.
|x| + 5 = 13 reduces to |x| = 13, so x could be either -13 or +13.
Answer:
Six cases are enough to construct more than one isosceles triangle
Step-by-step explanation:
An Isosceles triangle is a triangle in which at least two of it's sides are congruent.
If two of the three sides of a triangle are congruent, but the third side is of a different length, the triangle is isosceles.
If all three sides of the triangle are congruent, even though this is an equilateral triangle, it satisfies the condition of an isosceles, and it is ok to still it isosceles.
Julius might decide to split information for a better explanation, it doesn't matter the number of cases he has, but six cases should be enough to draw an isosceles triangle.
Function 1
rate of change = (80-100)/(2-1) = -20
y = -20x + 120
function 2
y = -18x + 120
rate of change = -18
answer
function 2 shows a greater rate of change

Answer: B) Complex numbers</h3>
Complex numbers are always in the form a+bi with 'a' and 'b' as real numbers.
If b = 0 and 'a' is nonzero, then a+bi = a+0i = a which is strictly a real number
If a = 0 and b is nonzero, then a+bi = 0+bi = bi indicating that the number is now purely imaginary
