You first have to turn 2x + 4y = -8 into y = mx + b before graphing. To do this, you subtract 2x from the left side of the equation because inverse operations. This will bring 2x to the right side. Now, you will have 4 = -2x + 8. However, you cannot have a number with y. Therefore, you must divide -8 and 2 by 4. You will get y = -1/2 x + 2 as your equation.
To graph -1/2x + 2, you must remember rise/run. Since it is NEGATIVE -1/2, your slope will go downwards (1 down, 2 across) starting from y = 2.
Answer:
$6.40
Step-by-step explanation:
2.56 / 16 = 0.16
so 16 cents per oz
16 * 40 = 640
Answer:
l.c.m of 15 and 5 is 15
next step is to equalize the denominator with the l.c.m value
11/15 is the same (same denominator)
3/5 will change to 9/15 (multiply numerator and denominator by 3 to equalize)
Lastly, you just need to subtract
11/15 - 9/15
2/15
