Answer:
a) x = 10 + -1.5y
b) y+15
Step-by-step explanation:
a)2x+3y=10*√4
2x+3y=20
2x + 3y + -3y = 20 + -3y
2x + 0 = 20 + -3y
2x = 20 + -3y
x ÷ 2 = (20 + -3y) ÷2
x = 10 + -1.5y
b)x+2y+5*3=x+y
x+2y+15=x+y
x+2y+15 - y=x+y - y
x+y+15 =x
x+y+15 - x =x - x
y+15
If you can graph in slope intercept, your new equations would be: y= -2x-1 and y= 2/3x-3.
Just graph those now since it should be easier.
<em>Greetings from Brasil...</em>
According to the statement of the question, we conclude that the area of a square is requested, whose value is 171 in²
The area of a square is given by the expression:
A = S²
<em>where S is the side of the square - just what we want to know</em>
So:
A = S²
171 = S²
√171 = S
<h3>S ≈ 13.08in</h3>
