Evaluate 4 2/3-(-1 4/5)

Mathematics
1 answer:
Blababa [14]3 years ago
3 0
Find a common denominator by multiplying the two different denominators by each other to get 15. 2/3 then becomes 10/15 and 4/5 becomes 12/15.

You now have 4 and 10/15 minus negative 1 and 12/15. Subtracting a negative number results in addition, so it's 4 and 10/15 PLUS 1 and 12/15. You get 5 and 22/15, which becomes 6 and 7/15.

The answer is C.

 An integer is an element of the numeric set that contains the natural numbers {N} = {1,2,3,4, ...}, its opposite and zero.
 On the number line we find the negative numbers to the left of the zero and to its right the positive numbers.
 We have then, according to the definition, that the following are whole numbers:
 -527, 1
 Answer:
 
B = {x | x is an integer}
 
-527 ∈ B

F(x) = 3x^2 -15<br> g(x) = 1 -2/3x
Oliga [24]

Answer:

f(g(-6)) is equal to 60

Step-by-step explanation:

We can simply solve this by first plugging -6 into function 6, and then applying function f to the result of that.

f(g(-6))\\= f(1 - \frac{2(-6)}{3})\\= f(1 - \frac{-12}{3})\\\\= f(1 + 4)\\= f(5)\\= 3(5)^2 - 15\\= 3 * 25 - 15\\= 75 - 15\\= 60

What do all members of the family of linear functions f(x)=1m(x+3) have in common?
dsp73
All linear functions have in common...
1. Their highest exponent is 1.
2. The graphs of the equations are lines.

When finding things in common between different types of functions, you always have to look at the two sides of math; geometry and algebra. Geometry is all the graphs, and algebra is the equations.

I hope this helps!
