Which of the following lines are parallel to 2Y - 3X = 4?
dimulka [17.4K]

Answer:

B. Y = 6/4 X

Step-by-step explanation:

Well to find its parallel line we need to put,

2y - 3x = 4 into slope-intercept.

+3x to both sides

2y = 3x + 4

Now we divide everything by 2,

y = 3/2x + 2

So a line that is parallel to the given line will have the same slope but different y intercept, meaning we can cross out choices A and C.

To check look at the image below ↓

<em>Thus,</em>

<em>answer choice B. Y = 6/4 X is correct.</em>

<em />

<em>Hope this helps :)</em>

The infinite sequence $T=\{t_0,t_1,t_2,\ldots\}$ is defined as $t_0=0,$ $t_1=1,$ and $t_n=t_{n-2}+t_{n-1}$ for all integers $n&g
katrin [286]

t_n are the Fibonacci numbers,

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ...

Taken modulo 7, we get the sequence

0, 1, 1, 2, 3, 5, 1, 6, 0, 6, 6, 5, 4, 2, 6, 1, ...

that repeats with period 16 (this is known as the 7th Pisano period).

This is to say,

t_a\equiv t_{16n+5}\equiv t_5\equiv5\pmod7

t_b\equiv t_{16n+10}\equiv t_{10}\equiv6\pmod7

t_c\equiv t_{16n+15}\equiv t_{15}\equiv1\pmod7

so that

(t_a+t_b+t_c)\equiv(5+6+1)\equiv\boxed5\pmod7

Parallel, perpendicular, or neither? 5x+3y=7 3x+5y=4
emmainna [20.7K]
Neither. They can’t be parallel because both lines have different slopes. They aren’t perpendicular either because their slopes don’t multiply to equal -1.

jolli1 [7]
Well 25% is the same as .25 or 1/4. So first you need to add X and Y so X+Y and since it is both you choose D
