Y=kx+1 M(2,-7) What is K

Mathematics
1 answer:
Karo-lina-s [1.5K]3 years ago
7 0

Answer:

K = 5m+y/x

Step-by-step explanation:

Let's solve for k.

y=kx+1m(2−7)

Step 1: Flip the equation.

kx−5m=y

Step 2: Add 5m to both sides.

kx−5m+5m=y+5m

kx=5m+y

Step 3: Divide both sides by x.

kx/x = 5m+y/x

Therefore, k = 5m+y/x

A cloud directly above you is about 10° across. From the weather report, you know that the cloud is at an altitude of 2200 m. Ho
Fudgin [204]

The width of the cloud is 12500 meters wide.

The situation forms a right angle triangle.

<h3>What is a right angle triangle?</h3>

Right angle triangle are triangle that has one of its sides as 90 degrees. The sides can be found using trigonometric ratios.

Therefore, the altitude is the opposite side of the triangle formed. The width of the cloud is the adjacent side of the triangle formed.

tan 10 = opposite / adjacent

Therefore,

tan 10° = 2200 / a

cross multiply

a = 2200 / tan 10°

a = 2200 / 0.1763269807

a = 12500 meters

Therefore, the width of the cloud is 12500 meters .

RUDIKE [14]

The ratio of time taken by Henry to time taken by Gavin is 3:5

Step-by-step explanation:

Time taken by Henry for each set = 36 minutes

Time taken by Gavin for each set = 1 hour

We will convert Gavin's time into minutes.

Time taken by Gavin for each set = 60 minutes

Ratio;

Time taken by Henry : Time taken by Gavin

36:60

Dividing by 6

\frac{36}{6}:\frac{60}{6}\\6:10
