A.-2 opposite
To positive 2
Given: y²+5y
Converting y²+5y in the form: x²+2ax+a²
Here 2a=5 or a=5/2
Add and subtract (5/2)²
y²+5y+(5/2)²-(5/2)²
Complete the square.
(y+5/2)²-(5/2)²
Simplify
(y+5/2)² - 25/4
Answer: (y+5/2)² - 25/4

Answer:
I'm not going to give you an exact answer because there could be many different ones
Step-by-step explanation:
The equations can be rewritten as:
2x - 7 = 7y
-4x + 19 = 3y
then you just insert a value for x and get the answer.
Answer:
7
Step-by-step explanation:
So if w/5 = 49/35, then you can take w/5 and make the denominator 35 by multiplying the top and bottom by 7:
w/5 * 7/7 = 7w/35
So then you have:
7w/35 = 49/35
Which means:
7w = 49
w = 7
