Answer:
1. d. x-intercept is -4; y-intercept is 8.
2.d. x-intercept is 16; y-intercept is 20
3. b. -x+6y=24
4. a. 4.75k+2.25p=22
Step-by-step explanation:
1. -10x+5y=40
to find the y intercept let x =0
5y = 40
divide by 5
y = 40/5 = 8
to find the x intercept let y =0
-10x = 40
divide by -10
x = 40/-10
x=-4
2. 5x+4y=80
to find the y intercept let x =0
4y = 80
divide by 4
y = 80/4 = 20
to find the x intercept let y =0
5x = 80
divide by 5
x = 80/5
x=16
3. Write y=1/6x+4 in standard form using integers.
Ax+by =c
multiply each side by 6
6y = 6* (1/6 x + 4)
6y = x+24
subtract x from each side
-x+6y = x-x+24
-x +6y = 24
4. lbs of kumquats * price/per + lbs of pears * price/lb =22
k * 4.75 + p * 2.25 =22
4.75k + 2.75p = 22
the memory is the independent, because that can vary at will, so it's independently varying at will, whilst the amount of songs are limited to how much memory there's in the CD, so the songs are dependent on the memory availability.
Alice has read 0.75*200 = 150 pages. The number of pages in Nina's book is
