Answer:
There are many ways to interpret if whether or not a system of equations has solutions or not. Here is one way that is most ideal for most, if not, all equations: using graphs.
- If the graphs of the set of equations do NOT intersect, then there are no solutions (because no x or y value will ever make both equations true)
- If the graphs of the set of equations DO intersect at one point, then ONLY that one point will make both equations true. (One solution)
- If the graphs of the set of equations are identical on the graph, then there are infinite solutions that make both equations true.

Answer:
13.7
Step-by-step explanation:
The computation of the volume of toy A is shown below:
7 × k^2=9
k^2= 9 ÷ 7
k=√9 ÷ 7
k = 1.133893419
Now
= 20 ÷ 1.133893419³
=13.7
Answer:
Quadrant 4
Step-by-step explanation:
Csc = 1/sin
Cos is positive in quadrants 1 and 4
Sin is negative in quadrants 3 and 4
Slope is -2/3 and y-intercept is 400
Step-by-step explanation:
- Step 1: The slope-intercept form of an equation is y = mx + b where m is the slope and b is the y-intercept. Rearrange the given equation to this form to find m and b.
2x + 3y = 1200
3y = -2x + 1200
y = -2/3x + 400
∴ m = -2/3 and b = 400
