Answer:
43.5 unit^2.
Step-by-step explanation:
Area of the triangle
= 1/2 * base * height
= 1/2 * AB * AC.
AB = √ [(6-1)^2 + (6-8)^2] = √29
AC = √ [(8 - (-7))^2 + (1 - (-5)^2] = √261
So the area = 1/2 * √29 * √261
= 43.5
The <em><u>equation of a straight line</u></em> is an equation that comes in the form of an algebraic equation. It is also referred to as <u>Slope - Intercept form.</u> It can be represented using the equation below:
Equation : y = mx + c
where:
<u><em>m = Gradient</em></u>
<u><em>c = Slope of the line</em></u>
The equation that shows how the price of a personal pizza y, depends on the number of toppings x is y = 7 + x
This question can be solved and represented using the equation of a straight line.
Let's represent
- y = price of a personal pizza
- The price for a plain cheese pizza = $7
- The price for each of the toppings = $1
Therefore, the equation that shows how the price of a personal pizza y, depends on the number of toppings x is written as:
y = $7 + $1 * x
y = 7 + x

Answer:
6m + n + 2
Step-by-step explanation:
[7m + 3n - 11 - 2m] + [n + 5 - -m - 3n + 8]
[5m + 3n - 11] + [n + 5 + m - 3n + 8]
5m + 3n - 11 + (-2n + 13 + m)
5m + 3n - 11 - 2n + 13 + m
6m + n + 2
