<span>For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a . Example 1: Find the axis of symmetry of the parabola shown. The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.</span>
{ y = 3 x - 4
9x -3y = 14
Subsititute y = 3x-4 :
[ 9 x - 3 ( 3 x-14 )=14]
Refine:
9 x - 3 ( 3 x - 4 ) = 14
- 2 = 0
is false , therefore the system of equations has no solution
Answer A
hope this helps!
1.5 tsp x 800 cakes = 1200 tsp.
1 tsp = 5 ml
1200 x 5 = 6000 ml
1 ml = 0.001 liter
6000 x 0.001 = 6 liters
Answer:
4
Step-by-step explanation:
4 because 4^2 = 16.
Answer:
Width = 2x²
Length = 7x² + 3
Step-by-step explanation:
∵ The area of a rectangle is 
∵ Its width is the greatest common monomial factor of
and 6x²
- Let us find the greatest common factor of 14 , 6 and
, x²
∵ The factors of 14 are 1, 2, 7, 14
∵ The factors of 6 are 1, 2, 3, 6
∵ The common factors of 14 and 6 are 1, 2
∵ The greatest one is 2
∴ The greatest common factor of 14 and 6 is 2
- The greatest common factor of monomials is the variable with
the smallest power
∴ The greatest common factor of
and x² is x²
∴ The greatest common monomial factor of
and 6x² is 2x²
∴ The width of the rectangle is 2x²
To find the length divide the area by the width
∵ The area = 
∵ The width = 2x²
∴ The length = (
) ÷ (2x²)
∵
÷ 2x² = 7x²
∵ 6x² ÷ 2x² = 3
∴ (
) ÷ (2x²) = 7x² + 3
∴ The length of the rectangle is 7x² + 3
