for each line state the slope, for a bonus state the slope l l & ⟂ to the slope of the given line
Answers
Answer:
Slope of line = [tex]\frac{1}{2}[/tex]
Slope of parallel line = [tex]\frac{1}{2}[/tex]
Slope of perpendicular line = (-2)
Step-by-step explanation:
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
[tex]m_1=\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, equation of a line passing through points (1, -3) and (-1, -4) will be,
[tex]m_1=\frac{-4-(-3)}{-1-1}[/tex]
[tex]=\frac{1}{2}[/tex]
If the slope of a line parallel to the given line is [tex]m_{2}[/tex],
Then by the property of parallel lines,
[tex]m_1=m_2[/tex]
Therefore, slope of the parallel line will be [tex]\frac{1}{2}[/tex].
Property of perpendicular lines,
[tex]m_1\times m_2=-1[/tex]
[tex]\frac{1}{2}\times m_2=-1[/tex]
[tex]m_2=-2[/tex]
Therefore, slope of the perpendicular line will be (-2).

Identify The domain of the rational function, g(x)= 1/x+3
A (-∞, ∞)
B (-∞, 3)U(3, ∞)
C (-∞, -3]U[-3, ∞)
D (-∞, -3)U(-3, ∞)
Answers
Answer:
The domain is (-∞ , -3) ∪ (-3, ∞) ⇒ D
Step-by-step explanation:
The domain of the rational fraction is the values of x which make the fraction defined. That means the domain does not contain the values of x which make the denominator equal to 0.
∵ g(x) = [tex]\frac{1}{x+3}[/tex]
∴ The denominator = x + 3
→ Equate the denominator by 0
∵ x + 3 = 0
→ Subtract 3 from both sides
∴ x + 3 - 3 = 0 - 3
∴ x = -3
→ That means the domain can not have -3 because it makes the denominator
equal to 0
∴ The domain is all values of real numbers except x = -3
∴ The domain = {x : x ∈ R, x ≠ -3}
∴ The domain = (-∞ , -3) ∪ (-3, ∞)

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
Given;
Profit of business in first month= $4,312.31
Loss of business in first month= $1,025.19
Total profit= Profit - loss
=4312.31-1025.19
=3287.12
So, the profit made will be $3287.12

A recipe for blueberry muffins states that it yields 12 muffins, with 270 calories per muffin. You instead decide to make
mini-muffins, and the recipe yields 20 mini-muffins. If you eat 7 mini-muffins, how many calories will you consume?
Answers
Answer:
If you eat 7 mini-muffins, will you consume 1134 calories.
Step-by-step explanation:
A recipe for blueberry muffins states that it yields 12 muffins, with 270 calories per muffin.
i.e.
No of muffins = 12 muffinsCalories per muffin = 270 caloriesTotal calories of standard muffins = 270 × 12 = 3240 calories
If the same amount of calories are made by 20 mini-muffins, then the total number of calories per mini-muffin will be:
3240/20 = [tex]162[/tex] calories per muffin
As you ate 7 mini-muffins.
Thus,
Your eaten calories = 162 × 7 ∵ 162 calories per muffin
= 1134 calories
Therefore, if you eat 7 mini-muffins, will you consume 1134 calories.
