Here’s a written work of the question hope this helps
Part A: 3x + 15 = 5x - 25
Part B: x = 20
Answer:
Step-by-step explanation:
1). y = - 4x + 7
Reflected across what????
if x-axis, then y ⇒ - y
So the answer would be <em>y = 4x - 7</em>
2). <em>y = 2x - 14</em>
3). <em>y = 2x - 8</em>
4). <em>y = 12x + 9</em>
Answer:
Step-by-step explanation:
The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ is the central angle formed at the center of the circle.
r represents the radius of the circle.
π represents a constant whose value is 3.14
From the information given,
r = 21 inches
θ = 25 degrees
Length of arc formed = 25/360 × 2 × 3.14 × 21 = 9.2 inches,
