Answer:
52
Step-by-step explanation:
This one was difficult one but is made to equations like such.
x+7=2y
x+y-9=13
using substitution i came to
x(the first number)=12.333
y(the second number)=9.667
hope i helped
Answer:
i need help this too ,but I don't know how I make this
Option D - Decreasing then increasing
Step-by-step explanation:
Step 1 :
The graph(plot) of the function given f(x) = x^2 is a parabola which opens upwards
The function keeps decreasing as x increases for negative values of x
It reaches the origin for x = 0
Then the function increases as x increases for positive values of x
Step 2 :
Based on the inference in step 1 we can get that the graph of the given function decreases first and them increases.
Hence option D - decreasing then increasing describes the given function.
