Answer:
3\2 is her walking rate I think but sure
Step-by-step explanation:
Y=1/3x+6
where x is your age and y is your brothers age
This is a geometric sequence where r = -3.
4 x -3 = -12
-12 x -3 = 36
36 x -3 = -108
-108 x -3 = 324
Answer: 324
4x - 3y = -11
-7x - 8y = 6
We need to cancel out one of the variables so let's multiply the first equation by 8 and the second by 3 and aim to cancel y.
32x - 24y = -88
-21x - 24y = 18
Now we subtract,
53x = -106
x = -2
3y = 4x + 11 = 4(-2) + 11 = 3
y = 1
Answer: (x,y)=(-2,1)
Check:
4(-2) -3(1) = -8 - 3 = -11, good
-7(-2) - 8(1) = 14 - 8 = 6, good
By this equation: d = 4(32), we know what d equals, which means we have the value of d.
d= 4*32
d = 128
