Writing an Equation to Represent a Real-World Problem
Caitlin is designing a railing for a set of stairs. The railing Which function can represent the height, y, of the
will begin at a height of 36 inches and follow the slant of railing in inches according to the horizontal distance in
the stairs, which decreases 9 inches for every 12 inches, x, from the top of the stairs?
horizontal inches
y=-3x + 36
4.
O y=-3x + 36
36 in
© y = x + 36
y = 3x + 36

send it over

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
