Please answer this question thx ❤️ y=x+1 4x + y = 6
1 answer:
Step-by-step explanation:
Hey there!
Here, The equations are:
y = x+1........(i)
4x + y = 6........(ii).
Now,
Putting equation (i) in (ii)
4x + y = 6
4x + (x + 1) = 6
5x + 1 = 6
5x = 6-1
Therefore, x= 1
Putting the value of x in equation (i).
y = x+1
y = 1+1
Therefore the value of y is 2.
<u>Check</u><u>:</u>
y = x+1
2 = 1+1
2=2 ( True ).

Answer:
x = - 6
Step-by-step explanation:
Given
x² = 24 ( multiply both sides by 3 )
2x² = 72 ( divide both sides by 2 )
x² = 36 ( take the square root of both sides )
x = ± ← note plus or minus
x = ± 6
solutions are x = - 6, x = + 6
The smallest solution is x = - 6
Let
x-------> the length side of the poster
y-------> the width side of the poster
we know that
Area of the poster is equal to
-------> equation
Area of the printed area is equal to
----> equation
substitute equation in equation
using a graph tool
Find the vertex of the graph
The vertex of the graph is the point that represent the value of x for the largest printed area
see the attached figure
the vertex is the point
the largest printed area is
find the value of y
therefore
the answer is
The dimensions of the poster are
