0 $\neq$ -1/3

False

B: (0,1)

1=-1/3(0)

1 $\neq$ 0

The engineers designing the All Aboard Railroad between Boca Raton and Jupiter decide to create parallel tracks through this por

olga2289 [7]

Answer:

there are no signs between the x and y and constant

it could be

2x+5y=15

2x+5y=-15

-2x+5y=15

2x-5y=15

for ax+by=c, the equation of a line paralell to that is

ax+by=d where a=a, b=b, and c and d are constants

(for this answer, I'm going to use 2x+5y=15)

given 2x+5y=15, the equation of a line paralell to that is 2x+5y=d

to find d, subsitute the point (4,-2), basically put 4 in for x and -2 for y to get the constant

2x+5y=d

2(4)+5(-2)=d

8-10=d

-2=d

the eqaution is 2x+5y=-2 (Only if the original equation is 2x+5y=-15

If the frequency of hba homozygotes is 0.1 what is the value of p2

Angelina_Jolie [31]

we know that

p^2 is the the frequency of hba homozygote

we are given

frequency of hba homozygotes is 0.1

so,

p^2 =frequency of hba homozygotes

we can plug values

and we get

$p^2=0.1$ ..............Answer

Twins issac and isaiah were just born issac weighs 6 pounds 2 ounces and isaiah weighs 5 pounds 4 ounces.How many ounces do issa

Ivanshal [37]

Answer: $11\ \text{pounds}\ 6\ \text{ounces}$

Step-by-step explanation:

Given

Issac and Isaiah born weighing 6 pounds 2 ounces and 5 pounds and 4 ounces.

1 Pound is equivalent to 16 ounces

Issac weighs

$\Rightarrow 6+\dfrac{2}{16}\ \text{Pounds}$

Isaiah weighs

$\Rightarrow 5+\dfrac{4}{16}\ \text{Pounds}$

Their combined weight is

$\Rightarrow 6+5+\dfrac{2}{16}+\dfrac{4}{16}\\\\\Rightarrow 11+\dfrac{6}{16}\ or\\\\\Rightarrow 11\ \text{pounds}\ 6\ \text{ounces}$
