ERROR ANALYSIS Describe the error in evaluating the expression. X (x-2.9)2x= 1.8
(x - 2.9)2 = (1.8-2.9)2
= (-1.1)
= -1.21
The wrong value was substituted for x.
O The difference between 1.8 and 2.9 is incorrect.
o The value of (-1.1)? should be positive.
Correct the error in evaluating the expression.
The correct value of the expression is

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

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

answer:

c) the x-coordinate of the center of the circle increases by 3
