Answer:
D. a is equal to 
Step-by-step explanation:
Let us assume that segment PQ is 8 units, so that its midpoint M is at 4 units to both P and Q.
Given that X is the midpoint of PM, this implies that X is at 2 units to both P and M.
Then;
PX = aPQ
⇒ = a x 8
= 8a
Therefore, a must be equal to , so that;
PX = 8a
= 8 x
= 2 units
Thus, a is equal to is the correct option.

Hi, The.
The domain of a function is the set of all possible values for x. The range is all possible values for y.
You should be able to see these pretty easily from the graph. If I understand your function correctly:
f(x) = square root(x+2) - 3
then x cannot be less than -2. Your domain is x > -2. In interval notation [-2,∞)
The lowest value for y is -3 so the range is y > -3. In interval notation [-3,∞)
Hope this helps!
1 1/4 + 1 1/2
First change the mixed fractions into improper fractions.
Do this by multiplying the denominator by the whole number, then adding that to the numerator, leaving the denominator the same.
5/4 + 3/2
Now change the fractions so that they have a common denominator.
Here, you can use 4 as the CD, so leave the first fraction alone and just change 3/2.
3/2 = 6/4
5/4 + 6/4 = 11/4
11/4 can be changed into 2 3/4.
So the answer is 2 3/4 or 2.75.
It it would take Andrew less amount of time than Bailey so think if it took him 22 hours every day for 9 days than it took Bayli 24 hours every day for 9 days then u would compare them then u would have your anaer
Answer:
C
Step-by-step explanation:
The amount of hours she will babysit for is unknown, so it will be 2x. However, she will always get 5 dollars for the gas, so its a constant and does not have a variable.
