Answer:
It is 28 miles. It is much more simple than you are making it out to be in your head. Draw out the picture with 7 marks on a line. The first 3 marks were traveled Friday. After Friday, there are 4 marks left. On Saturday, 2 of those 4 remaining marks are traveled. On Sunday, the last two marks are traveled. The last two marks are 8 miles together, meaning that each mark is 4 miles a piece. Therefore, 7 times 8 is 28 miles.

Answer:
62.1467 square units (correct to four decimal places)
Step-by-step explanation:
Let's say the triangle is;
A(-7,5)
B(-4,1)
C(0,1)
Let's say also that AB = a , BC = b and AC = c
By measurement BC = 4 units , AB = 5 units (applying Pythagorean theorem) and AC = 8.1 units (correct to one decimal place) also through Pythagorean theorem.
Area of this triangle =
, where p is half the perimeter of the triangle
p =
units
Area =
= 62.1467 square units (correct to four decimal places)
Answer:
The equation of the straight line is x - 2y +6 =0
Step-by-step explanation:
<u>Explanation:</u>-
Given a point ( 2, 4) and slope m = 
The equation of the straight line passing through the point and having slope 'm'
y - y₁ = m ( x - x₁)
y - 4 =
( x - 2)
2( y -4) = ( x-2)
2 y - 8 = x -2
x - 2 y - 2 + 8 =0
x - 2y + 6 =0
The equation of the straight line is x - 2y +6 =0
