The first one IS a function. The rest are not.
Answer:
Step-by-step explanation:
Please type numerals and punctuation for your mixed numbers.
I will have to assume that you meant 2 5/6 and 1 1/3, and that you are subtracting 2 5/6 from - 1 1/3. If that is correct, then we determine the LCD and rewrite -1 1/3 using this LCD:
-1 1/3 -1 2/6
-2 5/6 -2 5/6
----------
-3 7/6 or -4 1/6
The best calculation of this difference is -4 1/6 and the best estimate is
-1 - 3, or -4
Answer:
180.8
Step-by-step explanation:
1. Add all the numbers
2. Divide the sum by 5
3. you get the answer
Answer:
A = 22a
B = 5
C = 3x
D = 2y
Step-by-step explanation:
<span>an equation for the line in point-slope form and general form is :
y = ax+b a : </span>slope ; the <span>Passing through (x' ; y')
</span>y' = ax'+b
y-y' =a(x-x') and : x' =-5 y' =6
calculate a :
let : y = ax+b .....(D)
....<span>y=7x-1...</span>.(D')
.(D) perpendicular to(D') : slope (D) × slope (D') = -1
slope (D') = 7
slop(D)×(7 = -1
slope (D) = -1/7
equation for the line : y-y' =a(x-x')
y-6 =(-1/7) (x+5)
