x2=36
We move all terms to the left:
x2-(36)=0
We add all the numbers together, and all the variables
x^2-36=0
a = 1; b = 0; c = -36;
Δ = b2-4ac
Δ = 02-4·1·(-36)
Δ = 144
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
x1=−b−Δ√2ax2=−b+Δ√2a
Δ‾‾√=144‾‾‾‾√=12
x1=−b−Δ√2a=−(0)−122∗1=−122=−6
x2=−b+Δ√2a=−(0)+122∗1=122=6
Answer:

E: (6,10)
Step-by-step explanation:
the image on the grid is after doin x- 1 and y-7
to get the preimage do the inverse , x + 1 , y + 7
note- a coordinate is written as (x,y)
so, add 1 to all the x's and 7 to all the y's on the coordinates on the grid!
and sorry for asking but, if this is right could i please get a thanks & brainliest recently a moderator deleted ALL my answers (over 400 answers) causing me to lose over 3k points so id appreciate it alot thanks xoxo
Answer:
un death somthing
Step-by-step explanation:
(12,200 + 16,211 + 12,050 + 11,350 + 13,325) / 5 = 65136/5 =
13027.2 <== this is the mean (average)
11,350 , 12,050 , 12,200 , 13,325, 16,211
median (middle number) = 12,200
there is no mode...a mode is a number that appears most often...all the numbers appear once in this data.
You just have to cross multiply. 20 x 285 = 5700. 5700 / 95 = 60.
