Answer: you would look for y and then once you have y you put it into desemos which is a graphing app and then you get your line
Step-by-step explanation: you would do +3x on both sides with out doing it to the 4y and the. You would get 4y =23+3x and then you divide everything by 4 even the 4y and then you would get y= 23/4 + 3/4x and then you put it into desemos and it will give you it graphed
Answer:
Width = 11.7 feet (To 1 decimal place)
Length = 23.5 feet (To 1 decimal place)
Step-by-step explanation:
w = Width
2w= Length
Area of rectangle = length * width
2w * w = 276
(Simplify expression)
2w² = 276
(Divide both sides by 2)
w² = 138
(Square root both sides to isolate w)
w = √138
w = 11.7473401245
w = 11.7 feet ( 1 decimal place)
2 ×11.7473401245 = 23.4946802489
Length = 23.5 feet (To 1 decimal place)
Answer:
Step-by-step explanation:
Solution by substitution method
3x+5y=7
and 4x-y=5
Suppose,
3x+5y=7→(1)
and 4x-y=5→(2)
Taking equation (2), we have
4x-y=5
⇒y=4x-5→(3)
Putting y=4x-5 in equation (1), we get
3x+5y=7
⇒3x+5(4x-5)=7
⇒3x+20x-25=7
⇒23x-25=7
⇒23x=7+25
⇒23x=32
⇒x=32/23
→(4)
Now, Putting x=32/23
in equation (3), we get
y=4x-5
⇒y=4(32/23)-5
⇒y=(128-115)/23
⇒y=13/23
∴y=13/23 and x=32/23
