Answer:
Step-by-step explanation:
36°
Answer:
1/3
Step-by-step explanation:
3x – 9y = 4
We need to solve for y
Subtract 3x from each side
3x – 9y-3x = 4-3x
-9y = -3x+4
Divide each side by -9
-9y/-9 = -3x/-9 +4/-9
y = 1/3 x -4/9
This is in the form y = mx+b where m is the slope and b is the y intercept
y =1/3x -4/9
The slope is 1/3
X=1 because when u put it in then u will find out.y=-1
Answer: C.) The total number of stamps is 35.
Step-by-step explanation:
Given the table :
No of 45-cent stamp - - - No of 65-cent stamp
- - - - - - - 18 - - - - - - - - - - - - - - 17
- - - - - - - 20 - - - - - - - - - - - - - - - 15
- - - - - - 22 - - - - - - - - - - - - - - 13
- - - - - - 10 - - - - - - - - - - - - - - - - 25
Verifying each option stated :
Total value of stamp:
Each row add up to 35. Example (18 + 17) = 35
(20 + 15) = 35
(22 + 13) =35
(10 + 25) = 35
Total value of stamp:
Using the first row:
45 cent = $0.45 ; 65 cent = $0.65
(10 * 0.45) + (25 * 0.65)
= $4.5 + $16.25 = $20.75
Not all rows add up to $19.15
The answer is the second graph (bottom one)
