Answer:
y=1/2x-2
Step-by-step explanation:
1. Find slop by subtracting y values over subtracting x values, which will get you the m value
-1+3 / 2+2 = 1/2
Answer: 7x+25y=15
Step-by-step explanation: combine all like terms
6- ounce packet rate = $0.72 .
In order to find the one ounce rate, we need to divide $0.72 by 6.
On dividing 0.72 by 6, we get $0.12.
<em>Therefore, first unit rate is $0.12 per ounce.</em>
3- ounces packet rate = $0.27.
In order to find the one ounce rate, we need to divide $0.27 by 3.
On dividing 0.27 by 3, we get $0.09.
<em>Therefore, second unit rate is $0.09 per ounce.</em>
<h3>So, we can say that each pair of rates is not equivalent. </h3>
Answer:
Part 9) The number of items on Emily's grocery list is 5 and the number of items on Bobby's grocery list is 13
Part 10) The height of the taller bookshelf is 4 feet and the height of the shorter bookshelf is 1 foot
Step-by-step explanation:
Part 9)
Let
x ----> number of items on Emily's grocery list
x ----> number of items on Bobby's grocery list
we know that
----> equation A
----> equation B
Solve by substitution
Substitute equation A in equation B

solve for x



Find the value of y

therefore
The number of items on Emily's grocery list is 5 and the number of items on Bobby's grocery list is 13
Part 10)
Let
x ----> the height of the taller bookshelf in feet
y ----> the height of the shorter bookshelf in feet
we have
----> equation A
Remember that

To convert inches to feet divide by 12
so

----> equation B
Solve the system by substitution
substitute equation A in equation B
solve for y
Find the value of x

therefore
The height of the taller bookshelf is 4 feet and the height of the shorter bookshelf is 1 foot
