3. y-intercept is when x=0, so 2. Slope is change in y divided by change in x, so 4/3, which rounds to 1.3.
4. the equation: y=mx+d, so substitute m for the slope and d as the y-intercept, so you get y=1.3x+2
5. When you look at the graph, when x=7, then y=80. So the student may get an 80.
Step-by-step explanation:
Exterior angle BOA = 250°
Interior angle BOA = 360°- 250° = 110°
Now,
(A) BDA = interior angle BOA / 2 = 55°( Property of circles)
(B) From the figure, we observe that AOBC is a cyclic quadrilateral (i.e. sum of opposite angles is 180°).
Therefore, BCA + BOA = 180°
BCA = 180° - 110° = 70°
Mass equals density times volume
480+10/100(480)
=480+48
=528
The total amount the friend paid to Lynne is $528.
