Triangle EFG has vertices E(2,1), F (6,-1) and G (1,-5) find the points of EFG after 180 degrees rotation

The points of EFG after 180 degrees rotation will be :  (-2,-1), (-6,1), (-1, 5).

Step-by-step explanation:

Given: Triangle EFG has vertices E(2,1), F (6,-1) ,and G (1,-5).

According to 180 degrees rotation rule:

Image of E : (-2,-1)

Image of F = (-6,-(-1)) = (-6,1)

Image of G = (-1,-(-5)) = (-1, 5)

Hence, The points of EFG after 180 degrees rotation will be :  (-2,-1), (-6,1), (-1, 5).

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
