2. Ronu's present age is "x “years and her sister Shaani's present age is twice of Ronu's age. Write following as algebraic expression
a) Ronu's present age
b) Ronu's age after 2 years
c) Shaani's present age
d) Shaani's age after 2 years
What hould be added to 100 to get - 132​

x = -232

Step-by-step explanation:

Ronu's present age is "x “years and her sister Shaani's present age is twice  of Ronu's age.

(a) Ronu's present age = x years

(b) Ronu's age after 2 years = (x+2) years

(c) Shaani's present age = 2x years

(d) Shaani's age after 2 years = (2x+2) years

Let x should be added to 100 to get -132.

x+100 = -132

x = -100-132

x = -232

Hence, -232 must be added to 100 to get -132.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
