If your class wins the contest, then the class will receive a pizza party. brooke’s class won the contest.

what conclusion can you make from the statements above? which law did you use to come up with your conclusion?

a.
brooke’s class will have fun eating pizza.
law of syllogism
b.
brooke’s class will have wings with their pizza.
law of detachment
c.
brooke’s class will have a pizza party.
law of syllogism
d.
brooke’s class will have a pizza party.
law of detachment

The correct answer is D. Brooke’s class will have a pizza party by the law of detachment.

Step-by-step explanation:

By definition, the lay of detachment establishes if these two statements are true:

Then:

In this case:

If your class wins the contest, then the class will receive a pizza party.

P: If your class wins the contest.

Q: The class will receive a pizza party.

Using P for Brooke's class:

P: If Brooke’s class wins the contest.

Q: Brooke’s class will have a pizza party.

.5 lb

step-by-step explanation:

12 in / 6 in =2 in

.25 x 2 = .5 lb

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
