2^x( not in math type) (so your answer would be 2 to the x power and x is whatever number you out in)
Using the mean concept, the expression that gives the average of the low and high temperatures is:
(-3 + 8)/2.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
In this problem, the two observations are -3 and 8, hence their average is given by:
(-3 + 8)/2.

Your answer is y = -1/2 and y = 2
To solve this quadratic we first need to subtract 2 from both sides to set it equal to 0, which gives us 2y² - 3y - 2 = 0
Then we just need to factorise it:
2y² - 3y - 2 = 0
(2y + 1)(y - 2) = 0
Now we can set each bracket equal to 0 and solve for y:
2y + 1 = 0
2y = -1
y = -1/2
y - 2 = 0
y = 2

Answer: That would be the third option
Step-by-step explanation:
Answer:
(-3, 7)
Step-by-step explanation:
ok so first take the square root of both sides, so you get (x-2)=5, since the square root gets rid of the power, and the square root of 25, is 5, and since we did a square root, we also have to do the - + thing, so the equation really is now x-2=(+-)5
subtract 2 from both sides, and you get x=(+-)5+2
Solving for x we get -5+2=-3
and also
5+2=7 since there was a positive, and a negative 5.
therefore x would equal (-3, 7)
