The number of races the team need to win today for the team to have a 75% success rate is 15
Number of attempt = 45
Number of winnings = 30
Percentage won so far = 30/45 × 100
= 66.67%
let
x = Number of races that tfe team needs to win to have 75% success rate
(30 + x) / (45 + x) = 0.75
Cross product
30 + x = 0.75(45 + x)
30 + x = 33.75 + 0.75x
x - 0.75x = 33.75 - 30
0.25x = 3.75
x = 3.75 / 0.25
x = 15
Therefore, the number of races the team need to win today for the team to have a 75% success rate is 15

Answer:
1. 4, -2
2. 3, 0
3. 1, -8
4. 0, 5
5. 2, 5
Step-by-step explanation:
the highest raised to power in a term is called degree
eg: -2x^4
here -2 is always 0
but x is 4
so the highest is 4
the number found in the term is called coefficient
eg: -2x^4
here the only number seen is -2
so the only number is -2
this is same for all term

<span>Domain is all values of x that can make a function valid
so, x is all real values
and range is all values of f(x) for the above domain
So, range is also all real values</span>
Answer:
Step-by-step explanation:
To find the inverse function switch variables out and solve for y
If
y=(x+3)/x swap variables to get
(y+3)/y=x then solve for y
y+3=yx
y-yx+3=0
y-yx=-3
y(1-x)=-3
y=-3/(1-x)
y=3/(x-1)
