Check graphically whether the pair of equations 2x-y=1 and x+2y=3 is consistent if so solve them graphically
1 answer:
Answer:
A(1,1)
Step-by-step explanation:
the system is :
2x-y=1
x+2y=3
so :
y = 2x-1 .....the line color : red
y= (-1/2)x+3/2......the line color : blue
the pair solution is the intersection point for this line : A(1 ; 1)

hello friend ☺
Given :
TV cost = 800 £
VAT = 20 %
Amount of VAT
= 20% of 800
= 800 × 20 /100
= 160 £
So Total cost of TV
= original price + VAT
= 800 + 160
= 960 £
Thanks ❤

Answer:
53 Meters.
Step-by-step explanation:
34*34 + 41*41 = 2837.
1156 + 1681 = 2837.
The square root of 2837 would be your answer.
34*34 + 41*41 = 53.26349 * 53.26349
a*a + b*b = c*c.
a² + b² = c².
