What is the equation in point-slope form of the line passing through (−2, 0) and (2, 8)?

1 answer:

5 0

To express the equation in a point-slope form, obtain first the slope of the line between the points. The slope, m, of this line is,

(y2 - y1)/(x2 - x1) = (8 - 0)/(2--2) = 2

The point-slope form of the line is generally expressed as

y - y2 = m (x - x2)

Thus, in this given the point-slope form is,

y - 8 = 2 (x - 2)

Two groups collect litter along the side of the road. It takes each group 5miniutes to clean up a 200-yard section. How long doe

Snezhnost [94]

2 miles = 3520 yards (Americans wtf)
200 yards for 1 group = 5 minutes
400 yards for 2 groups = 5 minutes
1 minutes for 2 group = 80 yards
3520 yards for 2 groups = (3520:80 or 3520:400*5) minutes
So the answer is 44 minutes.

The diameter of a circle is 3 cm. Find the circumference to the nearest tenth.

nika2105 [10]

Answer:

The answer is 9.4 cm.

Step-by-step explanation:

To solve for the circumference of the circle, use the circumference formula, which is C = 2 $\pi$ $r$ .

Next, in the problem, the circle has a diameter measure but no radius measure. To find the radius of this circle, divide the diameter (3 cm) by 2, and it will equal 1.5 cm. The radius is being divided by 2 because the radius of any circle is equal to half the diameter of the circle.

Then, plug in the information given from the problem into the formula, and the formula will look like C = (2) ( $\pi$ ) (1.5 cm).

Finally, solve the equation, and the answer is 9.4 cm.

15 points! True Or False<br><br> k = 2 over 3 is a solution to the inequality 18k + 4 > 18.

Lilit [14]

$18k+4\ \textgreater \ 18$
$18( \frac{2}{3})+4\ \textgreater \ 18$
$18 (\frac{2}{3})$
$(\frac{18}{1}) (\frac{2}{3})$
$\frac{(18)(2)}{(1)(3)}$
$\frac{36}{3}$
$=12$
$12+4\ \textgreater \ 18$
$16\ \textgreater \ 18$
Answer:
False

In the year 2003, a company made $6.5 million in profit. For each consecutive year after that, their profit increased by 8%. How

Sauron [17]

Answer:

$8,580,000 (rounded) = $9,000,000

Step-by-step explanation:

Keep in mind, 2007 is four years after 2003.

So, 8(%) • 4 = 32(%)

Over the course of 4 years, the companies profits increased by a total of 32 percent.

(*Write 6.5m in standard form)

6,500,000 + 32% = $8,580,000

8,580,000 (rounded up) = 9,000,000
