Step-by-step explanation:

Let's simplify step-by-step.

−x2+2x−2x2−3x+4+x2

=−x2+2x+−2x2+−3x+4+x2

Combine Like Terms:

=−x2+2x+−2x2+−3x+4+x2

=(−x2+−2x2+x2)+(2x+−3x)+(4)

=−2x2+−x+4

Answer:

=−2x2−x+4

Two gift shops sell postcards. Each gift shop charges a fixed amount per postcard. The prices, in cents, for different numbers o
Snowcat [4.5K]

1st gift shop:

120/4 = 30 cents each

180/6 = 30 cents each

390/13 = 30 cents each

 

2nd gift shop:

204/7 = 29.14 cents each

192/8 = 24 cents each

270 /9 = 30 cents each

360/10 = 36 cents each


 so if both gift shops have a fixed price then the 9 post cards would be the answer since it matches 30 each like the 1st gift store

A husband and wife have normal vision, although both of the couple's fathers are red–green color-blind, an inherited X-linked re
Mekhanik [1.2K]

Answer:

1/2

Step-by-step explanation:

Since the recessive gene is carried in the x chromosome and a father can only pass it to a daughter, the father doesn't have the disease nor carries it.

The mother carries the recessive gene because her father passed her his conditioned gene (only having one x chromosome), while her mother gave her a normal one so she can have normal vision.  

The chance of having a boy or a girl is 1/2 and the chance of this baby of having both recessive gene is null because in order to have a girl that is color blind both her x chromosomes must have the recessive gene, but the father can't pass it since he doesn't carries it. Therefore the combined probability is 1/2*(1-0) = 1/2.
