Answer:

$2x+3y=-6$

Step-by-step explanation:

Let the line is $y=mx+b$ where $m$ is slope and $b$ is $y-intercept$ .

The line is parallel to $2x+3y=3$ , slope of both the lines will be same.

Find the slope of $2x+3y=3$

$3y=3-2x\\y=-\frac{2}{3}x+1$

Slope of line $=-\frac{2}{3}$

$m=-\frac{2}{3}$

So the line will be $y=-\frac{2}{3}x+b$

It passes through $(3,-4)$ .

$-4=-\frac{2}{3}\times 3+b\\-4=-2+b\\b=-2\\$

Hence the line is $y=-\frac{2}{3}x-2$

$y=-\frac{2}{3}x-2\\3y=-2x-6\ \ \ \ \ \ \ (Multiply both sides by 3)\\2x+3y=-6$

Answer the following.

vodka [1.7K]

Answer:

(a) 51,100 kilometers.

(b) $y = 7.68 * 10^{-6}$ meters

Step-by-step explanation:

(a) When converting from scientific notation to standard notation, split the equation.

When solving $5.11 * 10^{4}$ , begin by calculating $10^{4}$ .

$10^{4}$ = 10,000

Multiply this by '5.11', resulting in:

5.11 × 10000 = 51,100 kilometers.

(b) When converting from standard form to scientific notation, count the number of zeros until the first non-zero digit. Therefore:

In 0.00000768, the '7' is placed 6 digits from the decimal. Recall that for decimals, the exponent is negative. Therefore in scientific notation, this equals: $y = 7.68 * 10^{-6}$
