y = x + 2
Step-by-step explanation:
General formula for any straight line:
y = mx + c
Where
m = gradient
c = constant
m = y2 - y1/x2 - x1
m = (4 - ( -2))/(2 - ( -4))
m = 6/6
m = 1
y = (1)x + c
y = x + c
Substitute any coordinate from the line of the equation.
4 = 2 + c
c = 2
substitute m and c into general formula
y = mx + c
y = x + 2
7 mph and started 1 mile from the house = 7x + 1.
The second day, he rode 10 mph = 10x.
Answer: D
-2, because when you subtract 12 from both sides you get -4 and then you would divide that by 2 which then gives you -2:)
We will apply Pythagoras theorem in a right triangle, which states
" Consider a right triangle with hypotenuse 'h' and two legs say 'b' and 'p'. Pythagoras theorem states that the square of hypotenuse is equal to the sum of the square of both the legs of a triangle".
Mathematically,
(Equation 1)
Length of hypotenuse (h)= 52 feet
Length of one leg (let b )= 20 feet
We need to calculate the length of another leg that is 'p'
Using Equation 1,

Substituting the values, we get




p = 48 feet
Therefore, Option D is the correct answer.
