Assuming the equation is
you can subtract 5 from both sides to get
Which means that the "positive version" of c has to be 4.
So, if c is positive, it must be 4 itself.
If c negative, it must be -4, so that when you change its sign it becomes 4 again.
So, the answer is
Answer:
y = 3/4x + 6
Step-by-step explanation:
6-3 3
------- = ------
0--4 4
y = mx + b
take coordinates for y and x out of (-4, 3) or (0,6)
6= 3/4 * 0 + b
6 = 0 + b
b = 6
Answer:
1) x > -12
Step-by-step explanation:
first, subtract 7 from each side of the inequality to get:
-2/3x < 8
multiply each side by the reciprocal of -2/3 which is -3/2 to get:
x > -24/2
notice the symbol has been reversed because that is the rule whenever you multiply or divide an equality be a negative value
simplified, answer is x > -12
<span>Each pepper shaker has 7/80 kilograms of pepper.
First, determine how much black pepper Brian distributed to all the pepper shakers. Do this by multiplying 7/10 by 7/8.
7/10 * 7/8 = 49/80
Now divide 49/80 by 7 to get the amount of pepper in each shaker. Division is the same as multiplication by the reciprocal, so multiply by 1/7. So
49/80 * 1/7 = 49/560 = 7/80
So each pepper shaker has 7/80 kilograms of pepper.</span>
