Answer:
The answer is one.
Step-by-step explanation:
I'm not exactly sure if I'm right , so sorry, if it's wrong
A line perpendicular to y = -2x + 5 will have an equation in the form of:
y = (1/2)x + b
Since the graph must intersect (-2,9), we plug in this point to solve for b.
9 = (1/2)*(-2) + b
9 = -1 + b
10 = b
So the equation is:
y = (1/2)x + 10
The answer is A.
Answer:
Step-by-step explanation:
![\sqrt{3} *\sqrt[5]{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D%20%2A%5Csqrt%5B5%5D%7B3%7D)
= 3^1/2 x 3^1/5 = 3^(1/2 +1/5) = 3^7/10
Answer: 6 - 5
<u>Step-by-step explanation:</u>
|z - 6| - |z - 5| ; z < 5
Since z < 5, then
|z - 6| will be the absolute value of a negative number. Replace the absolute value with a negative and parentheses:
-(z - 6) = -z + 6
|z - 5| will be the absolute value of a negative number. Replace the absolute value with a negative and parentheses:
-(z - 5) = -z + 5
Now subtract them without the absolute value signs:
-z + 6 - (-z + 5)
Distribute the negative sign:
-z + 6 + z - 5
-z + z = 0 which leaves:
6 - 5
