Answer:

y = 2x - 12

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3 + 4x = 2y - 9 into this form

add 9 to both sides

12 + 4x = 2y ( divide all terms by 2 )

6 + 2x = y ← in slope- intercept form

with slope m = 2

• Parallel lines have equal slopes, hence

y = 2x + c ← is the partial equation of the parallel line

To find c substitute (4, - 4) into the partial equation

- 4 =8 + c ⇒ c = - 4 - 8 = - 12

y = 2x - 12 ← equation of parallel line

The number from standard form to decimal form is as follows:

2.077 × 10⁻⁴ = 0.0002077

<h3>How to express number in standard form?</h3>

Standard form is a convenient way of writing very large or very small numbers.

Standard form is a way of writing a number so it is easier to read.

Standard form is like scientific notation and is typically used in science.

Standard form is like scientific notation and it is represented in the format as follows:

a × 10ᵇ

Therefore, the number is already in standard form but we can convert it back to decimal form as follows:

2.077 × 10⁻⁴ = 2.077 × 1 / 10000 = 0.0002077

Can someone please help me with these?

Vikki [24]

Answer:

Step-by-step explanation:

One way to find the union of two sets is to list all the elements of both sets in order, then delete any duplicates.

Here, joining the two sets gives ...

{1, 6, 2, 3, 14, 2, 9, 13, 1}

Putting these elements into numerical order, we have ...

{1, 1, 2, 2, 3, 6, 9, 13, 14}

I have highlighted the duplicates. Deleting those gives us the desired union of the two sets:

X ∪ Y = {1, 2, 3, 6, 9, 13, 14} . . . . . matches choice C

Given that v=√u*u- 2qs. Make q the subject of the equation. Find the value of q in the equation if v=8, u=12, and s=40

kifflom [539]

Answer:

Step-by-step explanation:

v=√u*u- 2qs

$\sqrt{20}$ x 20 - 2q40 = 8
$2\sqrt{5}$ x 20 - 2q40 = 8
40 $\sqrt{5}$ - 2q40 = 8
- 2q40 = 8 - 40 $\sqrt{5}$
-80q = 8 - 40 $\sqrt{5}$
q = (8-40 $\sqrt{5}$ ) / -80 = $\frac{-1 + 5\sqrt{5} }{10}$ = 1.018
