Answer:
x=2 and y=1
Step-by-step explanation:
Rewrite equations:
y=−x+3;y=x−1
Step: Solve
y=−x+3
Step: Substitute−x+3foryiny=x−1:
y=x−1
−x+3=x−1
−x+3+−x=x−1+−x(Add -x to both sides)
−2x+3=−1
−2x+3+−3=−1+−3(Add -3 to both sides)
−2x=−4−2x−2=−4−2
(Divide both sides by -2)
x=2
Step: Substitute2forxiny=−x+3:
y=−x+3
y=−2+3
y=1(Simplify both sides of the equation)

(f-g) (x) means to subtract g(x) from f(x)
F(x) = 2x^2 +3
g(x) = x^2
This becomes:
2x^2 + 3 - x^2 = x^2 +3
Answer:
The width is 7 meters and the length is 13 meters
Step-by-step explanation:
The perimeter of a rectangle sandpit is 40 meters.
Let the width be w units, then the length which is 1 meter less than twice it’s width becomes:
The perimeter of a rectangle is given by:
We substitute P=40 and the length in term of w to get:
We simplify to get:
Divide through by 2 to get:
Hence
52 /100 x 50 : 700 * 36 so 2
