Answer:

12 years later.

Step-by-step explanation:

Let assume in X years, the table will be twice as old as the sofa.

36+X=2(12+X), X=12

Or think it the other way. The difference of ages between two things never change. So they must have a difference(of age) of 24 forever. When will this difference(24) be as same as the younger's age so that the older one is exactly twice as old as the younger? 12 years later when the sofa is 24.

Can someone explain y-intercept? I had a test, and I am pretty sure I bombed it. I really need help!!

Dvinal [7]

Y-intercept, it can be described as y-intercept form, or another way of writing it in mathematical form is y=mx+b, this can be used to draw polygons, find ortho-centers (very difficult), etc. m is the rise/run, rise over run, or 1/2. The rise and the run is the rate of change. b is the starting point or slope where it starts at, that is most of it!

A triangle has angles that measure 72.5 degrees and 32.7 degrees. What is the measure of the third angle?

astraxan [27]

72.5+32.7= 105.2
Triangle angles have to equal 180
180-105.2= 74.8
Third angle= 74.8 degrees

8k + 2m = 3m + k Solve for k

mina [271]

Minus both sides by 2m
$8k = 3 m - 2m + k \\ 8k = m + k$
Minus both sides by k
$7k = m$
Divided both sides by 7
$k = \frac{m}{7}$

Which relationship between x and y in the equation shows a proportional relationship

balandron [24]

Answer:

The equation y = 3x shows a proportional relationship between x and y

Step-by-step explanation:

The proportional relationship is represented graphically by a line passes through the origin point

The equation of the proportional relationship is y = m x

Let us solve the question

Substitute x by 0 to find the value of y, if y = 0, then the line represents this equation passes through the origin point, then the equation shows a proportional relationship

∵ y = 3x

∵ x = 0

∴ y = 3(0)

∴ y = 0

→ That means the line that represents the equation passes through

the origin point

∴ The equation y = 3x shows a proportional relationship between x and y
