Answer:
=45x√5x
Step-by-step explanation:
The provided expression is: 3√5x×3√25x²
We can simplify 3√25x² because √25x²=5x
3×5x=15x
Combine with the rest of the expression through multiplication.
3√5x×15x
=45x√5x
The expression 3√5x×3√25x² is equivalent to 45x√5x.
The expected simplified answer is 45x√5x
Answer:
x=101/65, y=-16/65. (101/65, -16/65).
Step-by-step explanation:
4x+9y=4
9x+4y=13
----------------
9(4x+9y)=9(4)
-4(9x+4y)=-4(13)
------------------------
36x+81y=36
-36x-16y=-52
----------------------
65y=-16
y=-16/65
4x+9(-16/65)=4
4x-144/65=4
4x=4+144/65
4x=404/65
x=(404/65)/4=101/65
x=101/65, y=-16/65.
The first graph is B. x^2 + 6 < 3
It is a parabola and opens upward when x^2 is positive. 6 raises it upwards by 6 units. the circle at
x = 3 means that the function can approach but not be equal to 3.
Check the picture below. You can pretty much just count the units off the grid.
