1.

a cell phone company offers two texting plans to its customers. the monthly cost, y dollars, of plan a is y = 0.12x + 7, where x is the number of texts. the cost of plan b is shown in the table. drag and drop the correct option into the box to make the statement true.

number of texts , x 100 200 300 400 500
cost ($),y 29 36 43 50 57

which plan is cheaper for under 300 texts?

for under 300 texts, (select plan b is cheaper, the plans cost the same amount , plan a cheaper )

2. solve
3.5d + 7.75 = 4 + 4.75d
the solution is d =

3.what is the solution of the system of equations?
y = 2x − 3
5x + y = 11

a. (2,1) b. (1,-1) c. (3,-4) d. (1,2)

step-by-step explanation:

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

answer: b
