Ben is decorating his home with vases of flowers. He bought glass vases that cost $22 each and ceramic vases that cost $14 each. The total cost of the vases came to more than $172. Also. Ben bought no more than 10 vases in all.
Which system of inequalities can be used to determine the number of glass vases, X, and the number of ceramic vases, y, that Ben could have
bought?
OA 22 + 147 > 172
+y<10
OB.225 + 147 > 172
I+y<10
OC 145 + 22y > 172
I+y<10
OD. 145 + 22y > 172
I + y < 10

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

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
