Answer:
the process of isolating a variable in these literal equations is similar to solving a one-step equation because after isolating a variable you solve the rest of the equation,it is different from solving a one-step equation because it is more than one step so it takes longer to solve
4a+9=(-9+30-25). 4a+9=30-34. 4a+9=-4. 4a=-13. A=-3.25 :)
Answer:
4
Step-by-step explanation:
80%=4/5
4/5 of 20 is 4
They lose 4 matches.
Answer:
5 1/8
Step-by-step explanation:
Just add and get a common denominator

The degree of f(x) is 4. Also the leading coefficient is 1 and it is positive
So as x approaches infinity then y approaches infinity
as x approaches -infinity then y approaches infinity
The first and fourth graph goes up and it satisfies the above . so we ignore the second and third graph.
Now we check the x intercepts of the first graph
x intercepts of first graph is -4 and 2
Plug in -4 for x in f(x) and check whether we get 0


Now plug in 2 for x and check

So -4 and 2 are the x intercepts that satisfies f(x)
Hence first option is the graph of
