Explain why x^2 + y^2 -6x +10y = -34 is NOT a circle. What is it?

Mathematics
1 answer:
kenny6666 [7]4 years ago
4 0

Answer:

(See explanation for further details)

Step-by-step explanation:

The expression is transformed into its standard form:

x^{2} + y^{2} - 6\cdot x + 10\cdot y + 34 = 0

x^{2} - 6\cdot x + 9 + y^{2} + 10\cdot y + 25 = 0

(x-3)^{2} + (y+5)^{2} = 0

The function does not represent a circle, as radius is a positive number.

Explain how you could add 678 + 303 using mental math
Vaselesa [24]
678 + 303 = 981

Here are a few examples to get you started:
600 + 300 = 900 
<span>78 + 3 = 81 </span>
<span>900 + 81 = 981
</span>Here's another one:
678 = 600 + 70 + 8 
<span>303 = 300 + 00 + 3 </span>
<span>Add the ones place = 11 </span>
<span>Add the tens place = 70 </span>
<span>Add the hundreds place = 900 </span>
<span>Now add 900 + 70 + 11 = 981</span>
Hope this helps! :-)

Which is a conditional statement for the sentence?
vova2212 [387]

The conditional proposition for the given sentence is:

"For all real numbers a, b, and c, if a = b, then a−c=b−c."

<h3>Which one is a conditional statement?</h3>

A conditional statement is of the form:

If P, then Q.

Where P and Q are two propositions.

The sentence is:

"For all real numbers a, b, and c, a = b implies that a−c=b−c."

So the propositions are:

P = "a = b"

Q = " a - c = b - c"

Where we need to define that this works for all real numbers.

So the conditional proposition is:

"For all real numbers a, b, and c, if a = b, then a−c=b−c."

So the correct option is C.
