The solution for given linear equation systems is (3,-4).
Option: C
<u>Step-by-step explanation:</u>
The given equations are 5x+3y=3 and x+y= -1.
Let us isolate x value from equation 5x+3y=3.
5x = 3-3y.
.
Substitute this x value in equation x+y= -1.
.
After taking LCM for the denominator,
.
3-3y+5y=-5.
2y=-8.
y=-4.
For
substitute the y value.
.
.
.
x=3.
∴ The solution is (3,-4).
Answer:
2 feet.
Step-by-step explanation:
Here the surface of the water is taken as the reference point. Let us take the depth of the swimmer below the water to be negative. Ali is 6 feet from the surface of the water so his height is -6. He then rose 4 feet so this need to be added to his initial height.
So, Ali has reached a height of
. Hence, Ali is 2 feet from the surface of the water.

Answer:
The correct answer is option D.
(4x² + 12x + 5)/(6x³ - 3x)
Step-by-step explanation:
It is given an expression in variable x
(2x + 5)/3x ÷ (2x - 1)/2x + 1)
<u>To find the correct option</u>
(2x + 5)/3x ÷ (2x - 1)/2x + 1)
= (2x + 5)/3x * (2x + 1)/(2x - 1)
= (2x + 5)(2x + 1)/(3x(2x - 1)
= (4x² + 12x + 5)/(6x³ - 3x)
The correct answer is option D.
(4x² + 12x + 5)/(6x³ - 3x)
