Y=-4x -3.......................
Answer:
x = 2.5.
y = 5.
Step-by-step explanation:
As they are image and pre-image of a dilation they are similar triangles, so the corresponding sides are in the same ratio.
4/2 = 5/x
2 = 5/x
2x = 5
x = 2.5.
Also:
4/2 = (y + 1)/ 3
2 = (y + 1) / 3
y + 1 = 6
y = 5.
f = -10 because you add 8f on both sides causing it to be 10+f=0
Then, you subtract 10 from both sides to get f = -10
There are 24 hours in a day, so 9 hours of the day is 9/24.
To reduce this, you need to recognize that both 9 and 24 are divisible by 3: 9=3x3 and 24=8x3
If you divide both by 3, you’d get your answer of 3/8.
You should sleep 3/8 of the day, when you’re 10 to 17 years old.
