Answer:
The y-intercept in coordinate form is (0, 4.5) and represents the taxi pick-up fee. The equation is y=1.5x + 4.5.
Step-by-step explanation:
This question is asking for the slope and y-intercept of a linear equation. A linear equation makes a straight line based on a constant rate of change. For this problem, the cost per mile is the slope, while the independent variable 'x' is the number of miles and the dependent variable 'y' is the total cost. In order to first find slope, you need to use the two points given (7, 15) and (10, 19.5) to set up a change in y / change in x, or (19.5-15)/(10-7) or 4.5/3 which is 1.5. So the slope, or cost per mile is $1.50. To find the y-intercept (b), or the cost of the pick-up fee, simply fill in your equation y=1.5x + b with your other variables and solve for 'b'. So, 15 = (1.5 x7) + b. or 15 = 10.5 +b, subtract 10.5 from both sides of the equation to get b=4.5.
Answer:
Camille did it right.
Step-by-step explanation:
4x-2y=8
Charlize: | Camille:
-2y=8+4x | -2y=8-4x
y=-4-2x | y=-4+2x
The right answer:
4x-2y=8
+2y +2y
4x=8+2y
-8 -8
2y=4x-8
2y/2=4x/2-8/2
y=2x-4 or y=-4+2x
So Camille is right, because she got y=-4+2x.
perimeter=2(85)+π(12.5)=220+2×12.5π
=170+25×3.14
=170+78.5
=248.5
distance ran=3×248.5=745.5 yards.
i hope this work for you

10 bows in total so every bow will be 10%
Since there is 4 purple bows the probability Nerissa will chose a purple bow is 40/100
