rationalise the denominator by multiplying both top and bottom by (8-5√3) then expand and simplify
Answer:
see explanation
Step-by-step explanation:
Given
f(x) = - 2x² + 4x - 2
To find the y- intercept set x = 0
f(0) = 0 + 0 - 2 = - 2 ← y- intercept
The equation of the axis of symmetry is of the form x = c
where c is the value of the x- coordinate the line goes through.
Given the equation in standard form
with a = - 2, b = 4 then the axis of symmetry is
x = - 
= - 
= 1
Equation of axis of symmetry is x = 1
Answer:x is 15

Answer:
6 soda's will cost $9.
Step-by-step explanation:
4 soda's costs $6.
Find the amount 2 soda's will cost. Divide 2 from both sides.
(4)/2 = 2
(6)/2 = 3
2 soda's will cost $3.
Now, solve for the cost for 6 soda's by multiply 3 to both sides.
2(3) = 6
3(3) = 9
6 soda's will cost $9.

Answer:
Step-by-step explanation:
so 30% of the total number of goals shot is 5
30% of what number is 5....turn ur percent to a decimal..." of " is multiply
let the number of shots represent x
0.30x = 5...divide borh sides by 0.30
x = 5/0.30
x = 16.66 shots
