1. Write 3-4 sentences describing how many acute and obtuse angles are created when 2, 3, or 4 parallel lines
are crossed by a single transversal that is not
perpendicular to them. Create pictures to help.
2. Identify how many unique acute angle measures there are
and how many unique obtuse angle measures there are,
explaining your reasoning.
3. Propose a generalization for when there are n parallel
lines, and confirm the generalization matches what was
found for the cases of 2, 3, or 4 parallel lines. Prove the
generalization, explaining all of your reasoning.

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
