Answer:
A
Step-by-step explanation:
Given a quadratic equation in standard form : ax² + bx + c = 0
Then the discriminant Δ = b² - 4ac informs us about the nature of the roots.
• If b² - 4ac > 0 then 2 real, distinct roots
• If b² - 4ac = 0 then 2 real , equal roots
• If b² - 4ac < 0 then 2 non real roots
x² + 6x + 14 = 0 ← is in standard form
with a = 1, b = 6, c = 14, then
b² - 4ac = 6² - (4 × 1 × 14) = 36 - 56 = - 20
Since b² - 4ac < 0 then 2 non real roots → A
Answer:
Option D y=3
Step-by-step explanation:
The question in English is
Which of the following functions is a constant function?
we know that
A <u>constant function</u> is a function whose output value is the same for every input value
so
<u><em>Verify each case</em></u>
case A) y=x+1
This is not a constant function, this is a linear equation
Is a function whose output value is different for every input value
case B) y=x+2
This is not a constant function, this is a linear equation
Is a function whose output value is different for every input value
case C) x=y+3
This is not a constant function, this is a linear equation
Is a function whose output value is different for every input value
case D) y=3
This is a constant function
Is a function whose output value is the same for every input value
Answer:
x = 6
Step-by-step explanation:
In similar triangles, corresponding sides are in same ratio
940,000 is your answer
You have to divide 135 from 540,000 and then multiply 100. Which is 400,000.
540,000+400,000=940,000.
If it’s not that, I’m sorry
