Since x is the x-intercepts, that means x'=x" =6 or in other word the discriminante ( Δ = b² 4ac) =0. Answer is A
Equation Form:
w x 2 
19
Divide both sides by 2:
w 9.5
So, w must be equal to or greater than 9.5 for this equation to work.

Step-by-step explanation:
Under a reflection in the line y = x
a point (x, y ) → (y, x ) , thus
(- 1, - 2 ) → (- 2, - 1 )
(1, 1 ) → (1, 1 )
(4, - 3 ) → (- 3, 4 )
Answer:
4×(34-12)+3×6
4×22+3×6
88+18
=106
Step-by-step explanation:
Apply the BEDMAS rule
B=brackets
E=exponents
D=Division
M=multiplication
A=addition
S=subtraction
The first step is to find the CHANGE. This is done by subtracting the two values and taking the absolute value. Next step is to find the ratio of the change to the original and multiplying by 100% to make it a percentage.
So;
a) change = Ι60 - 25Ι = 35.
ratio of change to original = 35:25,
multiplying by 100% will give 35/25 × 100% = 140%.
Hence it is a 140% INCREASE.
b) change = | 30 - 66 | = 36
the ratio is 36:66
multiplying by 100% = 36/66 × 100% = 0.545454... ×100% ≈ 54.5%
Hence it is a 54.5% DECREASE.
