If x + y is rational, must x and y each be rational?

1 answer:

8 0

No.

If a rational number can be an integer, x and y could be 5.5 and .5, or something that adds up to (number).0. This means, if the two non-rational numbers add up, they could be irrational, but the result isn't.

Which line is parallel to the line 8x + 2y = 12?

velikii [3]

Answer:

Step-by-step explanation:

Our line's equation is;

2y = -8x + 12

Dividing throughout by 2 we get;

y = -4x + 6

The slope of our line = -4

We are to choose a line whose slope is -4 (from those four options)

A slope of -4 means that for every positive 1 move along the x-axis, there is a negative 4 move along the y-axis.

The line that satisfies this condition is the third line.

Answer:

$1.62

Step-by-step explanation:

1. To find how much Erin spent, we have to multiply 0.54 by 3.

$0.54 * 3$
$(0.5*3)+(0.04*3)$
$1.5 + 0.12$
$1.62$

Therefore, Erin spent $1.62.

Answer: x=32

Step-by-step explanation:

$\frac{1}{8}x+8=12$

subtract 8 on both sides

$\frac{1}{8}x+8-8=12-8$

$\frac{1}{8}x=4$

multiply 8 on both sides

$8\cdot \frac{1}{8}x=4\cdot \:8$

$4\cdot8=32$

$x=32$
