What is the equation in point-slope form of the line passing through (1, 9) and (−1, 11)?

ololo11 [35]

Point slope form:
$y-y_1=m(x-x_1)$

m=slope
(x1,y1)

First we need to find the slope using the slope formula:
$\frac{y_2-y_1}{x_2-x_1} =slope$

Given the two coordinates:
(1, 9) and (−1, 11)

Plug them into the slope formula:
 $\frac{11-9=2}{-1-1=-2} =slope$
Simplify:
$\frac{2}{-2} =-1$

Now we know that:
m=-1 and the (x1,y1) would be (1, 9)

Now we simply plug in the info:
$y-9=-(x-1)$

Final answer: y − 9 = −(x − 1)

2+d=2-3(d-5)-2 Pls show work

defon

2 + d = 2 - 3(d- 5) - 2

First, cancel 2 on both sides. / Your problem should look like: $d = -3(d - 5) - 2$
Second, expand. / Your problem should look like: $d = -3d + 15 - 2$
Third, simplify -3d + 15 - 2 to get -3d + 13. / Your problem should look like: $d = -3d + 13$
Fourth, add 3d to both sides. / Your problem should look like: $d + 3d = 13$
Fifth, add d + 3d to get 4d. / Your problem should look like: $4d = 13$
Sixth, divide both sides by 4. / Your problem should look like: $d = \frac{13}{4}$

Answer as fraction: $d = \frac{13}{4}$
Answer as decimal: $d = 3.25$

A farmer saw some chickens and pigs in a field. he counted 30 heads and 84 legs. determine exactly how many chickens and pigs he

loris [4]

12 pigs×4 legs=48 legs
18 chickens×2 legs=36 legs
48 legs+36 legs=84 legs

12 are pigs and 18 are chickens

A ship sails from harbour h on a bearing of 084 for 340 km until it reaches point P. It the sails on a bearing of 210 for 160km

sattari [20]

Answer:

QH = 227.8 km ≅ 228 km

Step-by-step explanation:

∵ The bearing from H to P is 084°

∵ The bearing from P to Q is 210°

∵ The distance from H to P = 340 km

∵ The distance from P to Q = 160 km

∴ The angle between 340 and 160 = 360 - 210 - (180 - 84) = 54°

( 180 - 84) ⇒ interior supplementary

By using cos Rule:

(QH)² = (PH)² + (PQ)² - 2(PH)(PQ)cos∠HPQ

(QH)² = 340² + 160² - 2(340)(160)cos(54) = 51904.965

∴ QH = 227.8 km ≅ 228 km
