Answer:
The graph is nor a function og x because tha like y=0 intersects the graph at two points
Answer:
x ≈ 8.9
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, the the square of the tangent is equal to the product of the external part of the secant and the entire secant, that is
x² = 8(8 + 2) = 8 × 10 = 80 ( take the square root of both sides )
x = 
≈ 8.9 ( to the nearest tenth )
Answer:
1. y = 5x + 20
2. $20 the amount you saved mowing your aunt's lawn.
3. 21 weeks
Step-by-step explanation:
1. 5 is the slope because it is the rate. 20 is the y-intercept because that is how much you already have.
2. 20 because that is how much you already have.
3. Since you already have $20, you need to subtract 125 by 20 to get 105. Then you divide 105 by 5 to get 21 weeks.
