Help me please this is for a math test. <br> Thank you

Answer:

x + 3y = -12

Step-by-step explanation:

y = mx + b

m is the slope = rise / run:

rise = 1

run = 3

the line is downhill so its negative

m = - 1 / 3

b is the y intercept which is when the line cross over the y axis: - 4

y = - 1/3x - 4

multiply both sides by 3

3y = -1x - 12

add x to both sides

x + 3y = -12

Kelli swam upstream for some distance in one hour. She then swam downstream the same river for the same distance in only 6 minut
solmaris [256]

Answer:

6.11km/hr

Step-by-step explanation:

Let the speed that Kelli swims be represented by Y

Speed of the river = 5km/hr

Distance = Speed × Time

Kelli swam upstream for some distance in one hour

Swimming upstream takes a negative sign, hence:

1 hour ×( Y - 5) = Distance

Distance = Y - 5

She then swam downstream the same river for the same distance in only 6 minutes

Downstream takes a positive sign

Converting 6 minutes to hour =

60 minutes = 1 hour

6 minutes =

Cross Multiply

6/60 = 1/10 hour

Hence, Distance =

1/10 × (Y + 5)

= Y/10 + 1/2

Equating both equations we have:

Y - 5 = Y/10 + 1/2

Collect like terms

Y - Y/10 = 5 + 1/2

9Y/10 = 5 1/2

9Y/ 10 = 11/2

Cross Multiply

9Y × 2 = 10 × 11

18Y = 110

Y = 110/18

Y = 6.1111111111 km/hr

Therefore, Kelli's can swim as fast as 6.11km/hr still in the water.

VMariaS [17]

Answer:

This is a direct variation where the constant of variation is 5/9

Step-by-step explanation:

The equation for direct variation is y = kx

5x-9y =0

Lets try to get this equation in the above form

Add 9y to each side

5x-9y +9y = 9y

5x = 9y

Divide each side by 9

5/9 x = 9y/9

5/9x = y

This is in the form y = k x where k =5/9

Compare the functions shown below:
emmasim [6.3K]
The intersection with the y axis occurs when x = 0.
 We have then:
 
 For f (x):
 
f (0) = -3 (0) - 5&#10;&#10;f (0) = 0 - 5&#10;&#10;f (0) = - 5

 For g (x):
 
We can observe in the graph that when x = 0, the value of the function cuts to the y axis in y = -3

 For h (x):
 
h (0) = 2cos (2 (0) -\pi) +4&#10;&#10;h (0) = 2cos (0-\pi) +4&#10;&#10;h (0) = 2cos (-\pi) +4
 h (0) = 2 (-1) +4&#10;&#10;h (0) = -2 + 4&#10;&#10;h (0) = 2

 Therefore, the graph with the intersection with the largest y axis is h (x)

 Answer:
 
the greatest y-intercept is for:
