Answer:

Step-by-step explanation:

4x + 5y = 0 means : y=(-4/5)x

is the line passes by O(0 ; 0) when the slope is -4/5

Given that

ANEK [815]

Answer:

Given that,

R = 3x + 9y

Also, given that,

y = 6

R = 7

We have to find the value of x

For that, you can to put 6 and 7 to the equation instead of y and R respectively.

R = 3x + 9y

7 = 3x + 9 × 6

7 = 3x + 54

7 - 54 = 3x

- 47 = 3x

$\frac{-47}{3} = \frac{3x}{3}$

$\frac{-47}{3}=x$

Hope this helps you :-)

Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.

Nat2105 [25]

Answer:

Step-by-step explanation:

First choose two points on the line,

Let the points are A and B.

From point A to B we are moving downwards by (5 - 1 = 4 units)

Therefore, Rise = -4

Horizontal distance between A and B = 2 units

Therefore, Run = 2

Since, slope of a line = $\frac{\text{Rise}}{\text{Run}}$

Slope = $\frac{-4}{2}$

= -2

Find sum of three consecutive even integers if the largest integer is Y

KATRIN_1 [288]

Answer:

3y -- 6

Step-by-step explanation:

if the largest number is y, then the other two integers would be (y -- 2) and (y -- 4).

Therefore the sum of the integers would be

y + (y -- 2) + (y -- 4) = 3y -- 6.
