1 point Four students were discussing the equation given by their teacher shown below. Which student has the best understanding of the equation? 5x = 5x O Student 1: The equation has one solution, x = -4, because 5x cancels out on each side and all that is left is a -4 O Student 2: The equation has one solution, but it is -2/5, because after the like terms are combined, the result is 10x = -4 O Stude 3: The equation has infinite solutions because both sides of the equation contain the term 5x O Student 4: The equation has no solutions because when 5x is taken off both sides of the equation, the result is 0 = 4, which is false.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
