Answer:
Step-by-step explanation:
11) (-1, 4) (-5, 6) (-3, 10) Since it is reflected upon the y-axis it is the negative version of the x.
13) it is x = 5 because 2(x+1) is 2x+2 and so subtracting that from 3x you'd get x - 2 = 2x - 7. Simplifying that would be 5 = x.
y = a(x - b)^2 + c has vertex (b , c)
so here the vertex is (1, -36)
Answer:
They ate 0.75. I only wrote it as a decimal.
3÷4= 0.75 Hope it helps :)
Have a good day.
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
