Can u guys solve all this
1 answer:
Answer:
1) y = - 5/3x
2) y = - 4/3x
3) slope = - 1/17
4) slope = 6
6) y = -x - 1
7) y = -3/5x - 1/5
8) y = -x - 7
Step-by-step explanation:
5x + 3y = 0
3y = 0 - 5x
y = 0/3 - 5/3x or…
y = - 5/3x
- - - - - - - - - - - - - - - - -
4x + 3y = 0
3y = 0 - 4x
y = 0/3 - 4/3x or…
y = - 4/3x
- - - - - - - - - - - - - - - - -
(4, -9) , (-13, -8)
m = slope
m = change in y/change in x
m = (y2 - y1)/(x2 - x1)
m = (-8 - -9)/(-13 - 4)
m = 1/-17 or…
m = - 1/17
- - - - - - - - - - - - - - - - -
(8, 12) , (5, -6)
m = slope
m = change in y/change in x
m = (y2 - y1)/(x2 - x1)
m = (-6 - 12)/(5 - 8)
m = -18/-3
m = 18/3 or…
m = 6

6)
y = -x - 1
- - - - - - - - - - - - - - - - -
through (3, -2), parallel
to y = -3/5x
y = -3/5x + b
-2 = -3/5(3) + b
-2 = -9/5 + b
b = -2 - -9/5
b = - 1/5
The line would be y = -3/5x - 1/5
- - - - - - - - - - - - - - - - -
y = -x
(-5, -2)
-2 = 5 + b
b = -2 - 5
b = -7
The line would be y = -x - 7

Answer:
4
Step-by-step explanation:
Each walk-in is $5, so 20 divided by 5 is 4. 4 classes.
U must find the median, the range, and the mode. And that is your answer
Step-by-step explanation:
what was his starting balance ?
<h3>
Answer: 6 apples</h3>
x = number of apples originally
50% of x = 0.50*x = amount of apples eaten = 3
0.50x = 3
x = 3/0.50 ....... divide both sides by 0.50
x = 6
You can think of 50% as 1/2. If 3 apples represent half the bag, then the full bag is 6 apples. So half of 6 is 3.
