Answer:

30 and 32

Step-by-step explanation:

Because 31 is an odd numbers must be even. Just subtract 1 from 31 to get 30 and add 1 to 31 to get 32. Another way, just look at a number line and 31 is in between 30 and 32.

Enter an equation in point-slope form for the line. (6,8) and (7,1) is on the line. The equation of the line in point slope form

Yuri [45]

Answer:

$y - 8 = -7(x - 6)$ or $y - 1 = -7(x - 7)$

Step-by-step explanation:

The point-slope form equation is $y - b = m(x - a)$ , where,

(a, b) = a point on the line.

$m = slope = \frac{y_2 - y_1}{x_2 - x_1}$

Given the two points, (6, 8) and (7, 1), find the slope of the line:

$m = \frac{1 - 8}{7 - 6}$

$m = \frac{-7}{1}$

$m = -7$

There are two possible point-slope equation we can come up with using each points on the line given.

Using the point (6, 8) and m = -7,

Substitute m = -7, a = 6, and b = 8 into $y - b = m(x - a)$

$y - 8 = -7(x - 6)$

Using the point (7, 1) and m = -7,

Substitute m = -7, a = 7, and b = 1 into $y - b = m(x - a)$

$y - 1 = -7(x - 7)$

The area of a triangle piece of stained glass is 50 centimeters if the height of the triangle is four times the base, how long a

gavmur [86]

Answer:

Base = 5 cm

Height = 20 cm

Step-by-step explanation:

Points to remember

Area of triangle = bh/2

Where b - base of triangle

h - Height of triangle

<u>To find the Height and Base of given triangle</u>

It is given that,area of a triangle piece of stained glass is 50 centimeters

the height of the triangle is four times the base

h = 4b

Area = bh/2

50 = (b * 4b)/2

100 = 4b²

b² = 100/4 = 25

b =√25 = ±5

b = 5 then h = 4b = 4 * 5 = 20

Base = 5 cm and Height = 20 cm
