What is the equation of the line that passes through the point (-6, -8) and has a slope of 1/3

ivanzaharov [21]

Answer (assuming it can be in point-slope form):

$y + 8 = \frac{1}{3} (x+6)$

Step-by-step explanation:

With the given information, we can use the point-slope formula, $y-y_1 = m (x-x_1)$ , to write the equation of the line. Substitute values for the $m$ , $x_1$ , and $y_1$ in the formula to do so.

The $m$ represents the slope, so substitute $\frac{1}{3}$ in its place. The $x_1$ and $y_1$ represent the x and y values of one point the line intersects, so substitute -6 for $x_1$ and -8 for $y_1$ . This gives the following answer and equation (just make sure to convert the double negatives into positives:

$y-(-8) = \frac{1}{3} (x-(-6))\\y + 8 = \frac{1}{3} (x+6)$

Answer 1-6 (about square root)

Taya2010 [7]

Answer:

1. For a cube, volume = $edge^{3}$

2. $\sqrt[3]{volume}$ = edge

3. Volume of the cube = 216 so, the edge = $\sqrt[3]{216}$ = 6

4. 1st blank = 6

2nd blank = 6

3rd blank = 216

4th blank = 216

5. 6 is the edge

6. As the room is a square and we have to find the side

Area = 121

Edge = $\sqrt[2]{121}$ = 11

If my answer helped, kindly mark me as the brainliest!!

Thank You!!

Solve for y. 2x-3y=9

cluponka [151]

Answer:

y = 2/3x - 3

Step-by-step explanation:

Step 1: Write equation

2x - 3y = 9

Step 2: Solve for y

Subtract 2x on both sides: -3y = 9 - 2x
Divide both sides by -3: y = -3 + 2/3x
Rewrite: y = 2/3x - 3

Carbon-14 has a half-life of 5730 years. In a plant fossil, you find that the 14C has decayed to 1/8.00 of the original amount.

drek231 [11]

Note that 8.00 = (2.00)^3, that implies that a decay to 1/8.00 means that the Carbon-14 has passed 3 half-life. (1 to decay to 1/2, other to decay to 1/4, and other to decay to 1/8). And, three half-life is 3 * 5730 years = 17,920 years. So, the answer is that the plant was alive 17,920 years.
