2a+b=-7
5a+b=-13
b=-2a-7
5a-2a-7=-13
3a=-6
a=-2=first number
2(-2)+b=-7
-4+b+-7
b=-3=second
Answer: he has 128 + d
Step-by-step explanation:
well if he had 128 yesterday and today he got d more just add d to 128 and ull see
for example, lets say d = 16

Answer: 5 seconds
<u>Step-by-step explanation:</u>
Maximum height is the y-value of the vertex. The number of seconds at maximum height is the x-value (aka axis of symmetry).
h(x) = -2x² + 20x + 48
a=-2 b=20 c=48
Axis of symmetry: x = 
= 
= 
= 5
