Ten years ago. Phukan is 18 years younger than Namwan. Currently, the sum of their ages is 100 years. Find their current ages. WRITE AS AN EQUATION

Step-by-step explanation:

phukan = x

Nanwan = y

let this be a simultaneous equation.

x - y = 18 equation i

x + y = 100 equation ii

subtract equation i from equation ii

= 2y = 118

y = 59

substitute y = 59 in equation ii to get x

x + 59 = 100

x = 100- 59

x = 41

Nanwan = 59, Phukan = 41

Nawman = 59 years

Phukan = 41 years

Step-by-step explanation:

P = N - 18

P + N = 100

(N - 18) + N = 100

2N = 100 + 18

2N = 118

N = 118 : 2

N = 59 years

P = (59 - 18) years

P = 41 years

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
