Answer:
f(x+2) = - 6x - 5
Step-by-step explanation:
As we have f(x) =- 6x + 7, then we also have f(x+2) = - 6(x+2) + 7 = - 6x - 12 + 7 = - 6x - 5.
Answer:
25%
Step-by-step explanation:
The crossing between two heterozygous purple flowers can have the following results:
P from 1st flower and P from 2nd flower: PP -> 25% chance
P from 1st flower and p from 2nd flower: Pp -> 25% chance
p from 1st flower and P from 2nd flower: Pp -> 25% chance
p from 1st flower and p from 2nd flower: pp -> 25% chance
As the purple flower gene is dominant over the white flower, to have a white flower we need to have only white flower's genes, that is, pp.
So, the probability of the offspring will have white flowers is 25%
I feel like it would be 10 because they are both near 10 in running speed
The speed of slower car is 45 mph and faster car is 50 mph.
Step-by-step explanation:
Given,
Distance covered by both cars = 190 miles
Time taken by both of them = 2 hours
Let,
x be the speed of slower car.
Speed of faster car = x+5
Combined speed = x+x+5 = 2x+5
We know that;
Distance = Speed * Time

Dividing both sides by 4

Speed of slower car = 45 miles per hour
Speed of faster car = 45+5 = 50 miles per hour
The speed of slower car is 45 mph and faster car is 50 mph.
