Question 2:1 pts Frank and Angio are making pizzes for their business. If Frank can produce all of the nocesoary pizzas on his own in 8 hours and Angie can do tho same job in 4 hours, then what portion of the day's pizzas can they make together in 1 hour? O 1 10 O la ww O 12 Question 4:1 Kim and her little brother are picking strawberries. Actually, Kim picks the strawberries and her brother eats them out of the pail. If Kim could fill the pail in 16 minutes without her brother's intervention, and he can eat all the berries in 32 minutes, how long does it take Kim to fill the pail? O 20 min None of these 32 min 24 min 48 min Question

care to share were the trapezoid shown is ?

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
