× = 30-25
× = 5
Therefore, Emily has 5 apples :D
Hope it helps!!!

Answer:
Algebraically, linear functions are a two parameter family. The parameter a is called the function's y-intercept and the parameter b is called the slope. Together, they completely determine a linear function's input-output behavior. Notice that f(0) = a : The y-intercept is the output when the input is 0.
Answer:
(A) m = –3 and b = –3
Step-by-step explanation:
If m=–3 and b=–3
The system of linear equations:
y = –3x + 5
y = mx + b
Becomes
y = –3x + 5 ......(i)
y = –3x – 3 .......(ii)
Notice that 5 is added to -3x in (i) and -3 is added to -3x in (ii) and both equals y. This is impossible. Thus the system has no solution.
Answer:
<J=51°
Step-by-step explanation:
3x-2+4x-9+3x-9=180
10x-20=180
10x=200
x=20
<J=3x-9=3(20)-9=60-9=51°
