5 hours if you convert 180 kilometers to meters its 180,000 meters. 180,000 meters time 5 is 900,000
A triangle can't have two right angles because there is 180° in a triangle. Each right angle is 90° so it would be impossible
Answer:
x = 0
Step-by-step explanation:
= 2 - x ( square both sides to clear the radical )
x + 4 = (2 - x)² ← expand using FOIL
x + 4 = 4 - 4x + x² ( subtract x + 4 from both sides )
0 = x² - 5x ← factor out x from each term
0 = x(x - 5)
equate each factor to zero and solve for x
x = 0
x - 5 = 0 ⇒ x = 5
As a check
substitute these values into the equation and if both sides are equal then they are the solutions
x = 0
left side = = = 2
right side = 2 - 0 = 2
then x = 0 is a solution
x = 5
left side = = = 3
right side = 2 - 5 = - 3 ≠ 3
then x = 5 is an extraneous solution
Answer: y=-.667x+1
Step-by-step explanation:
1. Firstly, substitute the coordinates of the two points into the slope intercept equation:
(1) y₁ = mx₁ + b
(2) y₂ = mx₂ + b
2. Then, subtract the first equation from the second:
y₂ - y₁ = m(x₂ - x₁)
3. Finally, divide both sides of the equation by (x₂ - x₁) to find the slope:
m = (y₂ - y₁)/(x₂ - x₁)
4. Once you have found the slope, you can substitute it into the first or second equation to find the y-intercept:
y₁ = x₁(y₂ - y₁)/(x₂ - x₁) + b
b = y₁ - x₁(y₂ - y₁)/(x₂ - x₁)
