Parallel lines have the same slope. Since our reference line has a slope of -1, so will a line parallel to it. Thus far we have:
y=-x+b, using point (7,1) we can solve for b
1=-7+b
8=b so the parallel line passing through (7,1) is:
y=-x+8

12 total roses.
Probability of selecting a pink rose would be 3/12 or 1/4.
p(pink)=3/12=1/4
The complement of that would be 1-1/4=3/4.
P(NOT pink)=1-1/4=3/4
So theres a 3/4 chance that she WON'T randomly select a pink rose.

Answer:
4.4
Step-by-step explanation:
16.8 was for 4 hour
divide 4 by 16.8
you get 4.2 per hour
so you need 1 hour
1 hour would be 4.2
temp would be -4.2 at 9pm
Answer:
Low
Step-by-step explanation:
Low because it only overlaps twice.
Answer:
Ix - 950°C I ≤ 250°C
Step-by-step explanation:
We are told that the temperature may vary from 700 degrees Celsius to 1200 degrees Celsius.
And that this temperature is x.
This means that the minimum value of x is 700°C while maximum of x is 1200 °C
Let's find the average of the two temperature limits given:
x_avg = (700 + 1200)/2 =
x_avg = 1900/2
x_avg = 950 °C
Now let's find the distance between the average and either maximum or minimum.
d_avg = (1200 - 700)/2
d_avg = 500/2
d_avg = 250°C.
Now absolute value equation will be in the form of;
Ix - x_avgI ≤ d_avg
Thus;
Ix - 950°C I ≤ 250°C
