I guess you just do 4×3 then get get your answer if you have to show your work just do an array
Answer:
For the first equation
Twice a number added to a smaller number is 5 is written as
2x + y = 5
For the second equation
The difference of 5 times the smaller number and the larger number is 3 is written as
x - 5y = 3
Hope this helps you
Evaluate the function at the three values of the range and see what you get. The appropriate choice is ...
... D) {15, 3, 0}
_____
Evaluation can sometimes be simpler if you rearrange the function to a form called "Horner's form."
... f(x) = (x -4)x +3
Then the evaluation looks like (for x=-2) ...
... f(-2) = (-2-4)(-2)+3 = (-6)(-2) +3 = 12 +3 = 15
This is sufficient to identify D as the answer of choice.
Decay functions hav exponential terms that are one of
... (number greater than 1)^(negative exponent)
or
... (number less than 1)^(positive exponent)
The choice that meets these requirements is
... f(x) = 3/2 (8/7)^-x
Answer:
The first quadrant has both positive x, and y coordinates. The fourth quadrant has positive x coordinates but negative y coordinates. The given point is on the boundary between these quadrants where the x coordinates are positive and the y coordinate is always 0; it is called the positive x axis.
