Answer:
x = 19.5
Step-by-step explanation:
-2x + 7 = -32 (subtract 7 on both sides)
-7 -7
-2x = -39 (Divide by -2)
x = 19.5
The solution is y = -5
What is Quadratic Equation?
A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c = 0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
Given data ,
Let the function be f ( x ) = y
And , y = x² + 2x - 8
So , f ( x ) = x² + 2x - 8
Substituting the value for x in the equation , we get
When x = -3
f ( -3 ) = ( -3 )² + 2( -3 ) - 8
= 9 - 6 - 8
= 9 - 14
f ( -3 ) = -5
When x = 1
f ( 1 ) = ( 1 )² + 2( 1 ) - 8
= 1 + 2 - 8
= 3 - 8
f ( 1 ) = -5
Hence , the value of y = -5

Answer:
Half of the 10-inch quesadilla is greater than the entire 5-inch quesadilla
Step-by-step explanation:
we know that
The area of a circle is equal to
where
r is the radius
step 1
Find the area of the 10 inch-round quesadilla
we have
substitute
step 2
Find the area of the 5 inch-round quesadilla
we have
substitute
step 3
Which is larger, half of the 10-inch quesadilla or the entire 5-inch quesadilla?
Compare
half of the 10-inch quesadilla is equal to ----> 
the entire 5-inch quesadilla ---->
therefore
Half of the 10-inch quesadilla is greater than the entire 5-inch quesadilla
