Answer:
y = 3/2x - 3
Step-by-step explanation:
y = 3/2x + b
3 = 3/2 (4) + b
3 = 6 + b
-3 = b
y = 3/2x - 3
<3
Answer:
23
Step-by-step explanation:
29 minus 6 equals 23
If 2/3 are blue, 1/3 are not, and if 5/8 of the rest are blue, 3/8 are red.
(3/8)(1/3) = 3/24 = 1/8
So, the 6 red boats are 1/8 of the total. If 1/8 is 6, then 8/8 is 48 total boats.
(1/8)t = 6
t = 6(8)
t = 48
25
-13
which equals 12
This is because the circles have areas of 9
and 4
respectively.
Plus we can tell the square has the area of 100 due to the fact that the diameters of the circles add up to 10, meaning the larger circle has a radius equal to 5 and an area of 25
. Subtract the other two from the larger one and you get your answer.
So you subsitute y=2/3x-4 for y in 2x+y=4 so
2x+(2/3x-4)=4
2x+2/3x-4=4
add like terms
2 and 2/3x-4=4
add 4 to both sidees
2 and 2/3x=8
2 and 2/3=6/3+2/3=8/3
8/3x=8
multiply both sides by 3/8 (makes 8/3=24/24=1/1=1)
x=(3*8)/8
simplify
x=3
subtitute x=3 into y=2/3x-4
y=2/3(3)-4
y=(6/3)-4
y=2-4
y=-2
