Answer:
the range of this function is [-7, 2) (Answer A)
Step-by-step explanation:
The "range" of this function is the list of all values that the function can take on according to the rule shown in the graph. The smallest such value (the smallest y-value) is -7, obtained when x = -2. The largest is just less than 2; we know this because there is an empty circle at (1, 2) instead of a shaded circle.
Thus, the range of this function is [-7, 2)
Answer:
y=1/2x-2
you write it in y=mx+b form

Answer:
0.49 or 49/100
Step-by-step explanation:
So what you have to do here is distribute the 4 to the numbers in the parenthesis next to it. You also have to distribute the 0.5 to the numbers in the parenthesis next to it. So then that would make your equation become 48x-22.4=1.5x+0.35. After this step, you then have to solve for the variable, x. To do this, you would have to go backwards using PEMDAS, so first you add the 22.4 to the other side, making the equation 48x=1.5x+22.75. Then you would subtract 1.5x to the opposite side, makint the equation 46.5x=22.75. Now once you're here, you will divide the 46.5 by 22.75, making x roughly equal 0.49, or if you prefer a fraction form, then 49/100.
I think that it might be "c" but I am not sure but hey it is worth a shot sorry if I am wrong!
