x + y = 9
x + y = 9
- x - x
y = -x + 9
xy = -360
x(-x + 9) = -360
x(-x) + x(9) = -360
-x^2 + 9x = -360
+ 360 + 360
-x^2 + 9x + 360 = 0
-1(x^2) - 1(-9x) - 1(-360) = 0
-1(x^2 - 9x - 360) = 0
-1 -1
x^2 - 9x - 360 = 0
(x + 15)(x - 24) = 0
x = -15 or x = 24
The two numbers that multipky to -360 and 9 are -15 and 24.

Answer:
a=6
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 8^2 = 10^2
a^2 + 64= 100
a^2 +64-64 = 100-64
a^2 = 36
Take the square root of each side
sqrt(a^2) = sqrt(36)
a = 6
Answer:
a = 6
- The length of side a is 6.
Step-by-step explanation:
According to the question,
Using Pythagorean theorem
( a )² + ( b )² = ( c )²
- Where, a and b are the base and c is the length of hypotenuse.
( a )² + ( 8 )² = ( 10 )²
evaluate the exponent
a ² + 64 = 100
subtract 64 from each side
a ² + 64 - 64 = 100 - 64
a ² = 36
Take the square root of each side
√a² = √36
a = 6
\[ y=\sqrt{x} \]
\[y= \sqrt{x+3} \]

Firstly we have to determine the domain of the function
The domain of the function is the set of values for which the function is real and defined.
In the function we can clearly observe that for the negative values of x , the value of y will not be real.
So, the domain for this function is or
.
The second function is
In this function we can clearly observe that for the values of x less than -3, the function is not real.
So, the domain for this function is or
As we know, the square root of negative numbers.
Hence, the x must be a positive value and greater than 0.
So, x:x∈[0,∞)
subtracting 3 from both sides
x:x∈[-3,∞)
B. You have to pay interest on charge cards but not on credit cards.
C. You have to pay interest on credit cards but not on charge cards.
Answers
The correct answer is:
C) You have to pay interest on credit cards but not on charge cards.
Explanation:
A charge card is a card in which you are required to pay the balance in full every month. Because of this, there is no charge that accrues from month to month, so there is nothing to charge interest on.
B. False
