AlekseyPX3 years ago

Answer:

5y + x = 5c

Step-by-step explanation:

Rewriting the equation, 15x - 3y = 7,

3y = 15x - 7

y = 5x - 7/3. The gradient is 5. The gradient of the perpendicular line is -1/5

The equation of the perpendicular to 15x - 3y = 7 passing through (0,c) is

(y - c)/(x - 0) = -1/5

(y - c)/x = -1/5

y - c = -x/5

y = -x/5 + c

5y = -x + 5c

5y + x = 5c

H(t)=(t+3)
Anarel [89]

Answer:

0

Step-by-step explanation:

h(t) = (t + 3)² + 5, -5 ≤ t ≤ -1

The average rate of change is the change in h over the change in t.

(h(-1) − h(-5)) / (-1 − (-5))

= ((-1 + 3)² + 5 − ((-5 + 3)² + 5)) / (-1 + 5)

= (4 + 5 − 4 − 5)) / 4

= 0

Find an expression which represents the difference when (6x-3y) is subtracted from (9x+2y) in simplest terms.
Alex73 [517]

Answer:

3x+5y

Step-by-step explanation:

Subtract (6x-3y) from (9x+2y):

(9x+2y)-(6x-3y)

This can also be seen as:

(9x+2y)-1(6x-3y)

Distribute the -1 to (6x-3y):

(9x+2y)-1(6x)-1(-3y)\\\\(9x+2y)-6x+3y

Simplify the parentheses:

9x+2y-6x+3y

Group like terms:

(9x-6x)+(2y+3y)

Combine:

3x+5y

This expression can't be further simplified. Therefore, 3x+5y is the answer.

:Done

So you start of by finding the median. The median in this case would be 43. Then you find the median of both the lower (36) and the upper (53) half of the data. Then the find the difference between those two number. So you would do 53-36 which would make the answer 17
