Write an equasion of the line in point-slope form that passes through the points (-16, 8) (4,2)

1 answer:

5 0

You start by finding the slope : y2 - y1 / x2 - x1

2 - 8 / 4 - (-16)

- 6 / 20

m = - 3 / 10

Point slope form : y - y1 = m( x- x1 )

You can pick either of the coordinates and substitute them in

POINT SLOPE FORM EQUATION : y - 8 = -3/10 ( x + 16 )

145 300 610 1230

Vlad1618 [11]

Multiplying by 2 and then adding 10 145*2=290+10=300
300*2=600+10=610
610*2=1220 + 10=1230
x=2 y=10
x+y=12

In a triangle the measure of the first angle is twice the measure of the second angle. the measure of the third angle is 8 degre

Rufina [12.5K]

Let's call the missing angles Q, R, and S. We know that Q = 2R and S = R - 8 and we also know that Q + R + S = 180. So that really just means that 180 = 4R - 8 Add 8 on both sides of the equal sign
188 = 4R So we divide on both sides of the equal sign by 4
47 = R And that means that Q = 2 * 47 So Q = 94 and S = 47 - 8 So S = 39
39 + 94 + 47 = 180
The missing angles are 39 degrees 94 degrees and 47 degrees.

Please help me in problem 8 I need help on it plzZ

Answer:

$a.\ -3\\b.\ 6\\c.\ -5\\d.\ 4$

Step-by-step explanation:

First, it is important to remember which are the Negative numbers and the Positive numbers.

The Positive numbers are defined as all those numbers that are greater than zero and the Negative numbers are defined as all those numbers that are less than zero.

Then:

a. "3 degrees below $0\°F$ " indicates that the temperature is actually $-3\°F$ , which is less than zero. Then, it is a negative number:

$-3$

b. Let be 0 represents the sea level, "6 feet above the see level" indicates that the number is positive:

$6$

c. "Lost 5 pounds" indicates that now the actual weight is 5 pounds less than the original, which indicates that it must be expressed as a negative number:

$-5$

d. "Found $\$4$ " means that now the actual amount of money is greater than it was before. Then, the number that represents this is a positive number:

$4$
