Answer:
A system of linear equations has one solution when the graphs intersect at a point. No solution. A system of linear equations has no solution when the graphs are parallel. Infinite solutions.

Answer:
2175
Step-by-step explanation:
y = k sqrt(x)
x = 625
y = 87
87 = k * sqrt(625)
87 = k * 25
87/25 = k
k = 3.48
y = 3.48 * sqrt(390625)
y = 3.48 * 625
y = 2175
Answer:
it is 60
Step-by-step explanation:
you add all the numbers than you round it, the number is 0 so it stays the same, hope it helps, murdle
The answer is .90º + 90º = 180º, <span>.90º is not an obtuse angle</span>
Answer:
21 degrees
Step-by-step explanation:
Triangles have a total angle of 180 degrees.
This makes our equation:
3x+3+4x+135=180
Subtract 135 from both sides and combine like terms
7x + 3 = 45
Subtract 3 from both sides
7x = 42
Divide both sides by 7
x = 6
Plugging the number in:
3x + 3 =
3(6) + 3 =
21
