You did the correct thing and now you need to simplify the question. The answer would be -1. 0 squared is 0 and 4 times 0 is 0. That would leave you with -1.

Step-by-step explanation:
The high school boys vary in height more than the middle school boys.
middle school boys range = 169 − 164 = 5 cm
high school boys range = 183 − 175 = 8 cm
Answer:
D) (1,-5)
x = 1
y = -5
Step-by-step explanation:
y = 3x - 8
y = -9x + 4
substitute for y:
3x - 8 = -9x + 4
reduce:
12x = 12
x = 1
y = 3 - 8
y = -5
Answer:
He made the following mistake, he assumed that polynomial , having for granted that has two real roots, instead of two complex roots.
Step-by-step explanation:
He made the following mistake, he assumed that polynomial , having for granted that has two real roots, instead of two complex roots. The true factorized form of the fourth grade polynomial is:
The domain x ∈ {-5; 0; 5}
the relation: 2x + y + =1 → y = 1 - 2x
Put the values of x from domain to the equation of the relation:
for x = -5 → y = 1 - 2(-5) = 1 + 10 = 11for x = 0 → y = 1 - 2(0) = 1 - 0 = 1for x = 5 → y = 1 - 2(5) = 1 - 10 = -9
Answer: {-9; 1; 11}
