A line passes through (1,6) and has a slope of 9
BaLLatris [955]

Answer:

The answer is 9x - y - 3 = 0

Step-by-step explanation:

The line passing through the point (x₁, y₁) and has a slope of m,

y – y₁ m(x – x₁)

where, (x₁, y₁) = (1, 6) and m = 9

y – 6 = (9)(x – 1)

y − 6 = 9x – 9

-9x + y – 6 + 9 = 0

-9x + y + 3 = 0

Divide both side by (-1) we get,

-9x + y + 3/(-1)= 0/(-1)

9x - y - 3 = 0

Thus, The answer is 9x - y - 3 = 0

Naddika [18.5K]
Depends on how big of rows and columns (side to side or up and down) 3 by 4 for black and white and 3 by 6 for color just reverse the numbers so it'll be in stead 4 by 3 and 6 by 3 hope this makes sense

|3-v| < 6

1) Write the inequality as two inequalities without absolute value:
1st inequality:   3 < 6
2nd inequality: -v < 6

2) 
|3-v| < 6
<u>-3       -3</u>
|-v|   < 3
  v < 3

v = 2

3 - v < 6
3 - 2 < 6

We need help finding the means of the sides of this figure.<br> (Photo attached)<br><br> Thank you
VikaD [51]

Answer:

3) 5

4) 8.2

5) 6.8

6)FG = 6.4

7) EF = 3.6

8)DF = 4.8

Step-by-step explanation:

From the attached triangle, using trigonometric ratio we can find ∠G as; tan^(-1) (6/8)

Thus, ∠G = 36.87°

Still using trigonometric ratios;

FG/8 = cos 36.87°

FG = 8 cos 36.87°

FG = 6.4

3) EF + FG = EG

Since EG is 10, mean of EF and FG = 10/2 = 5

4) mean of EG and FG = (10 + 6.4)/2 = 8.2

5) EF + FG = EG

Thus; EF = EG - FG

EF = 10 - 6.4

EF = 3.6

Mean of EG and EF = (10 + 3.6)/2 = 6.8

6) FG = 6.4

7) EF = 3.6

8) Using trigonometric ratio;

DF/8 = sin 36.87

DF = 8 × 0.6

DF = 4.8
