Answer:
The equation of the graphed line written in standard form is:x-y=0
Step-by-step explanation:
we know that for graphing lines the equation of a line must be in standard form.
the standard form of a line is given by
where a,b,c are some real numbers.
hence, in the given question for graphing our line we must use the equation
because on comparing it to the general equation of the line
we have here a=1, b=-1 and c=0.
therefore the standard form is: 
Answer:
P(x>278) is 0.16
Step-by-step explanation:
We are given that a normal distribution has a mean of 266 and a standard deviation of 12.
Mean = 
Standard deviation =
We are supposed to find P(x > 278)
So, Formula : 

Z=1
Refer the z table for p value
p value = 0.8413
P(x<278) is 0.84
P(x>278)=1-P(x<278)=1-0.84=0.16
Option A is true
Hence P(x>278) is 0.16
Answer:
4 + 5i
Step-by-step explanation:
To calculate this you have to combine the like terms until they cannot be combined any further:
7 + 10i + 4 - 10i - (7 - 5i)
11 + 0i - 7 - 5i
7 & 4 are liked terms so add them together + subtract 10i and 10i
4 + 5i <--- Final answer
Hope this helps!
Answer:
16a^2 + 4a or 4a(4a+1)
Step-by-step explanation:
Use the distributive property (or FOIL).
First, the 3a2 becomes 6a.
6a x 4a = 24a^2
4a x -2a = 8a^2
4a x 1 = 4a
Simplify.
24a^2 - 8a^2 + 4a
=16a^2 + 4a
Other options:
=16a^2 + 4a
=4a(4a+1)
Hope this helped.
