Use subsiution]
y=-3x+5
subsitute -3x+5 for y in second equation
5x-4(-3x+5)=-3
distribute
5x+12x-20=-3
add like terms
17x-20=-3
add 20 to both sides
17x=17
divide both sides by 17
x=1
now subsitute 1 for x
y=-3x+5
y=-3(1)+5
y=-3+5
y=2
x=1
y=2

Answer:
√2, pi.
Step-by-step explanation:
An irrational number cannot be written as a fraction a/b where a and b are integers ( not = 0)..
The weight of the second one will be 4 tons
1 3/5=1.6
2 1/2=2.5
2.5×1.6=4
Replace X in the equation with 0:
f(0) = 3-2(0)
f(0) = 3-0
f(0) = 3
