If the ordinate is three more than twice the abscissa and x E {-1,0,-1/3} which of the following sets of ordered pairs satisfies

almond37 [142]

<span>The ordinate is three more than twice the abscissa
</span>Ordnate: y; Abscissa: x
y=3+2x

x=-1→y=3+2(-1)=3-2→y=1→(x,y)=(-1,1)
x=0→y=3+2(0)=3+0→y=3→(x,y)=(0,3)
x=-1/3→y=3+2(-1/3)=3-2/3=(3*3-2)/3=(9-2)/3→y=7/3→(x,y)=(-1/3,7/3)

Answer: Option <span>A) {(-1,1),(0,3),(-1/3,7/3)}</span>

Juan did a survey in four butterfly parks and wrote the following observations: Butterfly Park Survey Park Number of Pink Butter

Elena L [17]

Answer:

Park Q has greatest percentage of pink butterflies.

Step-by-step explanation:

Butterfly Park Survey Park P Q R S

No, of Pink Butterflies 25 35 37 23

Total Number of Butterflies 53 64 75 55

Now we are supposed to find which park had the greatest percentage of pink butterflies

So, Percentage of pink butterflies in park P = $\frac{25}{53} \times 100=47.169\%$

Percentage of pink butterflies in park Q = $\frac{35}{64} \times 100=54.68\%$

Percentage of pink butterflies in park R= $\frac{37}{75} \times 100=49.33\%$

Percentage of pink butterflies in park S= $\frac{23}{55} \times 100=41.81\%$

So, Park Q has greatest percentage of pink butterflies.

So, Option B is true

Hence Park Q has greatest percentage of pink butterflies.
