Answer:
b = a + 3.75
Step-by-step explanation:
a = 4b - 15
You are solving for b. Isolate the b. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, add 15 to both sides
a (+15) = 4b - 15 (+15)
a + 15 = 4b
Next, divide 4 from both sides. Remember to divide from all terms.
(4a + 15)/4 = (4b)/4
b = (4a)/4 + (15)/4
b = a + 15/4
b = a + 3.75 is your answer

hope this helps, sorry if i get wrong
DO NOT PICK ANSWER IT IS WRONG.
2x^2 - 7
we can plug any values of x into this The domain is All Real x.
The graph will be a parabola opening upwards with a minimum value when x = 0 and f(x) will be = -7
so the range is f(x) <= -7 or (-∞, -7]
