Let's solve your system by substitution.
−3x+y=−2;y=4x
Rewrite equations:
y=4x;−3x+y=−2
Step: Solvey=4xfor y:
y=4x
Step: Substitute4xforyin−3x+y=−2:
−3x+y=−2
−3x+4x=−2
x=−2(Simplify both sides of the equation)
Step: Substitute−2forxiny=4x:
y=4x
y=(4)(−2)
y=−8(Simplify both sides of the equation)
Answer:
x=−2 and y=−8
Hey,
In isosceles triangles there r two equal sides .
Base angles is usually used for isosceles triangles ....
Diagonals are two lines which intersect each other...
Answer:
Hey there!
First, we want to find the side length of the large triangle.
1/2bh=y cm^2
bh=2y cm^2
Since b and h are the same here, we have b^2= 2y, 
.
And we have FC=
.
Area of shaded triangle: 
.
This is equal to: 
, or y/4.
Let me know if this helps :)
Answer:
Step-by-step explanation:
First make a ratio,
6:62.64
Now make an equation
6/62.64=4/x
solve for x...
x=41.76
