Step-by-step explanation:
You want the to find the value of k such that the y coordinate of the vertex is 0.
0=x2−6x+k
The x coordinate, h, of the vertex is found, using the following equation:
h=−b2a
h=−−62(1)=3
Evaluate at x = 3:
0=32−6(3)+k
k=9
Answer:
$20
Step-by-step explanation:
you divide 40 by the two tickets and get $20.
Answer
y=120
Step-by-step explanation:
2.5 ->100
3 -> y
y=(3*100)/2.5
y=120
Answer:
Step-by-step explanation:
he spent 75% of his savings to buy a camera that costs 325....
so 75% of his original savings is 325
let x represent his original savings...." of " means multiply.." is " means equals
75%(x) = 325....turn ur percent into a decimal
0.75x = 325.....divide both sides by 0.75
x = 325 / 0.75
x = 433.33 <=== ur answer
check...
0.75(433.33) = 325
324.99 (rounds to 325) = 325
