Y=1/2x-4
Perpendicular means it is opposite and the reciprocal. 1/2(4) = 2-4 equals -2.
(4,-2)
Hello from MrBillDoesMath!
Answer:
The last choice on the list, -z/y^7
Discussion:
-
(14x)^0 y^-7 z => m^0 = 1 if m <> 0
-1 * y^-7 z => y^-7 = 1/y^7
-z/y^7, which is the last choice on the list
Thank you,
MrB
Answer:
-a + 15
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
3(a + 5) - 2(a + a)
<u>Step 2: Simplify</u>
- Combine like terms: 3(a + 5) - 2(2a)
- Distribute 3: 3a + 15 - 2(2a)
- Multiply: 3a + 15 - 4a
- Combine like terms: -a + 15
You basically simplify for this one,18 / ? = 9
18/2=9
So in this case, 8*2 is 16! Hope this helps!
