Find y for x=0,1,2, and 3.<br><br> y=4-x
LenKa [72]
4 - (0) = y
4 - 0 = 4      y = 4

4 - (1) = y
4 - 1 = 3     y = 3

4 - (2) = y
4 - 2 = 2     y = 2

4 - (3) = y

Given the equation 3x - 4y = 8, which equation below would cause a consistent-dependent system?
Len [333]
3x - 4y = 8

y = mx + b ; m is the slope ; b is the y-intercept

-4y = -3x + 8
y = -3x/-4 + 8/-4
<u>y = 3/4 x - 2</u>

Need to check if the given choices have the same slope.

3x + 4y = -8
4y = -3x - 8
y = -3/4 x - 8/4 = -3/4 x - 2

6x - 8y = 12
-8y = -6x  + 12
y = -6/-8 x + 12/-8
y = 3/4 x - 1 1/2

9x - 12y = 24   This equation would cause a consistent-dependent system
-12y = -9x + 24
y = -9/-12 x + 24/-12
<u>y = 3/4 x - 2</u>  

16x + 12y = -10
12y = -16x - 10
y = -16/12 x - 10/12
y = -1 1/3 x - 5/6

If Jim Roller can paint a room in 3 hours while John Brush would take 5 hours, how long will they take if they work together?
andrew11 [14]

Answer:

4 hrs

Step-by-step explanation:

half of Jim Rollers time is 1.5 hrs, and half of John Brushs time is 2.5 hrs. The two combined is 4 hrs. Therefore, the answer is four hours.

This is basically finding the average of two numbers, and you can use multiple different equations to find the same answer.

3/2 + 5/2 =4

(3+5)/2 =4

5-3=2, then 2/2=1, 5-1=4
