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:
B
Step-by-step explanation:
the ideal way to put the equation would be x= 6 x 8 but since that is not an option B is the answer. the keyword is "each" that allows you to know that you will be multiplying those to numbers.
so the only one that allows you to multiply 6 and 8 is B when you multiply 6 to the other side.
2 and 4 are the answers that apply to this statement
Answer:
one pair of parallel sides.
Step-by-step explanation:
A trapezoid has just one pair of sides parallel.
The parallel sides if a trapezoid forms its base.
A parallelogram on the other hand, has two pairs of sides parallel.
The pair of parallel sides in the trapezoid are not congruent while the pair of parallel sides in a parallelogram are congruent.
