Solve this system of equations algebraically
Y+x= 19-2
x + y = 80
t. Isolate one variable in the system of equations.
y = -x²-x+19
y = -x + 80
-x+80=-82-x + 18
2 Use substitution to create a one-variable equation
3 Solve to determine the unknown variable in the equation
real number solution(s).
The system has

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
