The system of equations 6x+4y=14 and 9x+6y=c are linear equations
The value of c that makes the system have infinitely many solutions is 21
<h3>How to determine the value of c?</h3>
The system of equations are given as:
6x+4y=14
9x+6y=c
Divide through the second equation by 3
3x + 2y = c/3
Multiply through by 2
6x + 4y = 2c/3
Subtract the first equation from the above equation
6x - 6x + 4y - 4y = 2c/3 - 14
Evaluate the differences
2c/3 - 14 = 0
Add 14 to both sides
2c/3 = 14
Multiply by 3/2
c = 21
Hence, the value of c that makes the system have infinitely many solutions is 21

Answer:
x = 3.69 feet
11.69 x 13.69 feet
Step-by-step explanation:
new area = (8 x 10) x 2 = 160
(8 + x)(10 + x) = 160
80 + 8x + 10x + x² = 160
combine like terms:
x² + 18x - 80 = 0
factor:
(x - 3.69)(x + 21.69) = 0
x = 3.69
1. C) $30.00
If you find how much each Pound is worth, which is $2.50 you multiply that by 12 which is $30.00.
2. < because -3.4 is father from 0 on a number line and -2.1 is closest to 0 on the number line so -2.1 is greater than -3.4. | -3.4 < -2.1
3. C) 1/4 because you need to be able to turn the fraction into a decimal and you need to multiply 4 and 1 by 5 and that is 5/20 then you multiply 5 and 20 by 5 and that gives you 25/100 and now you can turn it into a decimal which is 0.25 and 0.27 is greater than 0.25.
4. A) I because if point S is at (-2, 10) it would be in quadrant II so if point T is a reflection of point S than point T is in the I quadrant because the y-axis is the vertical line going up and down. So you put point T across the y-axis which is
at (2, 10) in quadrant I.
