Answer:
It requires of two equations
Step-by-step explanation:
example:
2x +7y = 12
Answer:
The average speed is 
Step-by-step explanation:
we know that
To find out the average speed divide the distance by the time
Let
s -----> average speed
d -----> the distance in feet
t ----> the time in minutes

we have


substitute
Simplify

Sorry, I don't understand your question... But, if you're trying to find how triangles are congruent, congruent means Same Size and Same Shape.
Answer:
(0,−7)
Explanation:
To find the y-intercept of an equation, set x equal to 0 and solve: In the case of 2x−5y=35, let's replace all instances of x in the equation with 0 and solve for y: 2(0)−5y=35−5y=35−5y−5=35−5
y=−7
Thus, the y-intercept is at (x y)=
(0,−7).
