Which inequality models this problem? Nico finds two online stores both sell the same kind of party hats that he wants. Store A sells the hats for $7 each and does not charge for shipping. Store B sells the hats for $4 each and charges a flat rate of $9 for shipping. What is the minimum number of hats Nico will need to buy for the cost to be less at store B than store A?​

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
