Answer:
x>-2
Step-by-step explanation:
-9x-15<3
+15<+15 add 15 to both sides
_________
-9x<18
÷-9 <÷-9 divide both sides by -9, switch inequality _________ symbol when dividing by negative number.
x>-2 Answer
_________
$88
Explanation:
Adults $12x5 = 60
Child $7x 4=28
60+28=88
Answer:

Answer:

Step-by-step explanation:
Given the quadratic equation as:

Let us put
for simplicity of the equation:
Now, the equation becomes:

Now, let us try to solve the quadratic equation:

So, the solution to the given trigonometric quadratic equation is:

and

Let us try to find the values of
in the interval
.
can have a value equal to
in 1st and 2nd quadrant.
So,
can be

For
,

So, the answer is:

Answer:
y = √(3² + 3²)
9 = √(5² + x²)
Step-by-step explanation:
Diagram 1:
Hypotenuse = y
Opposite = 3
Adjacent = 3
y² = 3² + 3²
y = √(3² + 3²)
y = √(9 + 9)
y = √18
Diagram 2:
Hypotenuse ² = known leg² + unknown leg²
Hypotenuse = 9
Known leg = 5
Unknown leg = x
9² = 5² + x²
9 = √(5² + x²)
9² = 5² + x²
9² - 5² = x²
x² = 81 - 25
x = √ 56
