Answer:
5( x+5) (x-2)
Step-by-step explanation:
5x^2 + 15x -50
Factor out a 5
5(x^2 +3x - 10)
What 2 terms multiply to -10 and add to 3
5*-2 = -10
5-2 = 3
5( x+5) (x-2)
Answer:
Step-by-step explanation:
Answer:
-4(3-1)+2
-4x2+2
-8+2= -6
since there is only one - and one + the answer will be negative
The answer is choice D
-----------------------------------------
Explanation:
We can rule out choice B and choice C which are y = 2.4^x and y = 3.5^x respectively. Why can we eliminate these? Because they are growth functions (the bases are larger than 1). The graph shown is a decay function. It goes downhill as you read it from left to right.
The answer is either choice A or choice D
If we plug in x = -2 into the equations for A and D, we get
y = 0.65^x = 0.65^(-2) = 2.36686
y = 0.32^x = 0.32^(-2) = 9.765625
The result for choice D is much closer to what the graph is showing. The graph appears to have the point (-2,11) on the curve. So that's why choice D is the best answer.
Note: the graph is a bit small and its not entirely clear which points are on this graph other than (0,1). So this is a bit of educated guesswork.
To be honest the correct answer would be just 5 because of estimation
so it would be 5.1754386 circle the 5 underline the 1 and Badda bing Badda boom because if something is bigger than 5 you round up one if its lower than leave your beautiful number
