Answer:
2. Like terms: 5a 4. Lt: 4y, and y
coefficient: 2,-7 coefficient: 4, -3
Constant: 2,-7 constant: 4
3. like terms: 3h, 2h, and 6h can you follow these and do the remaining??
if no, I'll help u
coefficient: 3,2,6
constant: 9
By better I am assuming you meant faster so,
18 ÷ 2 = 9
22 ÷ 2.5 = 8.8
9 > 8.8
therefore Emily has the faster rate.
Center is at (h,k) in standard form:
(x-h)2 + (y-k)2 = r2
Center: (-8, -3)
Radius (r): sr49 = 7
