Answer:
Non linear( it doesn't go through the 0
Step-by-step explanation:
Let's use the SAS postulate! SAS means Side, Angle, Side. I would sometimes write this the other way and get in trouble, haha.
It technically means if a triangle that has a congruent angle between two congruent sides, it means it is congruent. Here is a picture.
Answer:
A: Store A will cost about $1.28 less
Step-by-step explanation:
Okay, let's find the unit rate of cost. To find that for store A, we divide 7.26 by 3, which gets us 2.42. For store B, we need to look for the first intersection. We find that at (20, 50). Let's divide 50 by 20. That gets us 2.50. Let's multiply 2.42 and 2.50 by 16. That gets us 38.72 for store A and 40 for store B. Let's subtract 38.72 from 40. That gets us 1.28. That means store A costs $1.28 less than store B. That makes our answer A.
Answer:
<em>x∈ -10,4</em>
Step-by-step explanation:
x+3<7, x+3≥0: -(x+3)<7, x+3<0- separate the inequality into 2 possible cases
x<4, x≥-3; x>-10, x<-3- solve the inequalities
x∈ [-3,4}; x∈ {-10,-3}- find the intersection
x∈{-10,4}- Find the union
