Shawn is buying towels for his apartment. he finds some green towels that cost $10 each and blue towels that cost $7 each. he wants to buy at least 6 towels but doesn’t want to spend more than $70. write a system of inequalities that represents the situation and then graph the solutions.

define the variables: let x = the number of green towels, let y = the number of blue towels.

inequality 1:

inequality 2:

one possible combination of green and blue towels:

one not possible combination of green and blue towels:

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.

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables
