Solve for d
d=5t+2
d=2+5t (divide both sides of the second one by two)
so they are both equal to d=5t+2
That means that the graph of the solutions to the system is a straight line - because every point on the line would be a solution to the system. It also means that the equation are equivalent. This means that every solution to the first equation is a solution to the second equation.
This question is poorly worded because they both go the same direction, but since parallel lines are defined as lines that never intersect, and these lines do intersect (they're the same line)...
Among the four, the false statement is "The graphs of the equations are parallel lines."
Answer:
b 12 hats for $48
Step-by-step explanation:
Answer:
B. 44.6 feet
Step-by-step explanation:
To find the height of the tree, create a proportion where x is its height:
=
Cross multiply and solve for x:
57x = 2542
x = 44.6
So, the tree is B, 44.6 feet
The equation of a line parallel to the given line and passing through the given point can be found by using the point-slope form of a linear function.
y - y₁ = m(x - x₁) where 'm' is the slope and (x₁ , y₁) is the given point.
Now first, we need to realize that parallel lines have the same slope. As a result, the line we are looking for will have a slope equal to our given line's slope, or 1/4
We just substitute into the equation as follows:
Now you can solve for y to put this into slope-intercept form if you like:
I hope it is useful for you:)
