The sum of two numbers is 15. One of the numbers is 12 times the other. Find the
bigger number.

The Sum of two number is 15: x + y = 15

One of the numbers is 12 times the other: x = 12y:

System of equations:

x + y = 15

x = 12y

Plug x = 12y into equation one(x + y = 15)

12y + y = 15

13y = 15

y = 15/3

y ≈  1.15

Now we know x = 12y

x = 12(15/13) = 180/13

x = 180/13

x ≈ 13.85

The biggest number is x = 180/13.

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:

yes
