Answer:
It's matched left by right side. Steps are not in order!
Step-by-step explanation:
1. Square both sides and simplify
2. Find the distance between the focus and the point on the parabola
3. Choose a point on the parabola
4. Write the equation of the parabola
5. Set the distance from focus to the point equal to the distance from directrix
to the point
6. Find the distance from the point on the parabola to the directrix
Answer: The equation that represents the other equation is
.
The solution of the system is <u>(3,6).</u>
Step-by-step explanation:
Linear equation:
, where m= slope
c = y-intercept.
In the first table, the y-intercept = 5 [ y-intercept = value of y at x=0.
Slope for first table = 
The equation that represents the first table:

So, the equation that represents the other equation is
.
Also, the solution of the system is the common point (x,y) that satisfy both equations in the system.
Here, x=3 and y=6 is the common value in both tables.
So, the solution of the system is <u>(3,6).</u>
Step-by-step explanation:
x is the independent variable
y is the dependent variable
Answer:
Step-by-step explanation:
total weight is 4 tons.
ratio of weight of truck to weight of coal is 7:5....added = 12
so 7/12 of the total weight is the truck's
and 5/12 of the total weight is the coal
7/12 of 4 tons = 7/12 * 4 = 28/12 = 2 1/3 tons <== weight of truck
5/12 of 4 tons = 5/12 * 4 = 20/12 = 1 2/3 tons <== weight of coal
