Answer:

The required equation of the line is y = [x]+2

Step-by-step explanation:

From the graph shown, we can see that the line dotted points forms a straight line. We are to find the required equation of the line formed.

The formula for calculating the equation of a straight line is expressed as y = mx+b where

m is the slope b is the y-intercept

<u>Get the slope 'm'</u>

m=\frac{y_2-y_1}{x_2-x_1}

Using the coordinate points (2, 0) and (4, 2)

m=\frac{2-0}{4-2}\\m=\frac{2}{2}\\m=1

<u>Get the y-intercept 'b'</u>

Substitute m = 1 and (2, 0) into y = mx+b as shown;

2=1(0)+b\\2=0+b\\b=2

Get the required equation. Recall that y = mx+b, hence;

y = 1x + 2\\y=x+2

The expression can also be written as  y = [x]+2

Answer:

x = 6

Step-by-step explanation:

The area of a triangle is equal to the base times the height divided by two. In this case, the base is 6 (or x, it doesn't really matter) and the height is x (or 6, it doesn't matter). That means that the area of this triangle is equal to 6 * x divided by 2, which is also equal to 18. we can say that 6x/2 = 18, meaning that 6x = 36, so x = 6.

sana is senior to Mona by 18 years after 6 years.Sana will be twice as old as Mona. find Mona,s percentage​
Gwar [14]
Let
Present age of Sana = s
Present age of Mona = m


Sana is senior to Mona by 18 years
s=m+18............(1)

After 6 years
Sana will be = s+6
Mona will be = m+6
Then
Sana will be twice as old as Mona
(s+6)=2(m+6)
s+6=2m+12
s=2m+12-6
s=2m+6.............(2)
Put the value of s from (2) to (1)
2m+6=m+18
2m-m=18-6
m=12
Put the value of m in (1)
s=m+18
s=12+18
s=30



Present age of Sana = s = 30 years old
Present age of Mona = m = 12 years old
