Answer:
1). The rate of change is 30 songs per week — it represents the number of songs Ivy will download every week. This was found by looking at the slope of the graph.
B). The initial value was 150 songs — it represents the maximum number of songs Ivy can download. It was found by looking at the y-intercept of the graph.
C). y = -30x + 150

37/76
Step-by-step explanation:
P=24+13/24+13+39=37/76
Left 9 down 5, inside the bars you flip the sign to go right or left, outside sign doesn’t change
Answer:
x = 7/5 or x = (-7)/5
Step-by-step explanation:
Solve for x over the real numbers:
49 - 25 x^2 = 0
Multiply both sides by -1:
25 x^2 - 49 = 0
x = (0 ± sqrt(0^2 - 4×25 (-49)))/(2×25) = ( ± sqrt(4900))/50:
x = sqrt(4900)/50 or x = (-sqrt(4900))/50
sqrt(4900) = sqrt(4×25×49) = sqrt(2^2×5^2×7^2) = 2×5×7 = 70:
x = 70/50 or x = (-70)/50
70/50 = 7/5:
x = 7/5 or x = (-70)/50
(-70)/50 = -7/5:
Answer:x = 7/5 or x = (-7)/5
