Yes the first one is a function. The second one with the arrows is not.
Answer:
-1/4x(-4/3) = 1/3
You can use caculator. It's really easy
Answer:
Subtracting with zero: 0 – a = –a. Use the rule for subtracting signed numbers: Change the operation from subtraction to addition and change the sign of the second number. Likewise, a – 0 = a. It doesn’t change the value of a to subtract zero from it.
Step-by-step explanation:
Answer:
A = 200.96 sq ft
Step-by-step explanation:
formula for area of a circle: A = π·r²
A = (3.14)·(8²)
A = 64·(3.14)
A = 200.96
Answer:
The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is 
Step-by-step explanation:
The standard form of equation is 
Finding slope
Using the given points (0,-4) and (-3,-2) we can find slope using formula:

Finding y-intercept
Using point (0,4) and Slope=-2/3 we can find y-intercept

The slope intercept form of the line through the given points. through (0.-4) and (-3,-2) having slope =-2/3 and b=-4 will be:

Now, standard form of equation will be: 
So, The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is
