4x + 5y = 3 kx + 15y = 9 find k

9966 [12]

Answer:

Step-by-step explanation:

4x + 5y = 3 ................ (i)

kx + 15y = 9................(ii)

Dividing eqn (ii) by 3, we get,

k/3 x + 5y = 3.............(iii)

Subtracting eqn (iii) by eqn (i), we get,

-4x - k/3 x = 0

or, -(4 - k/3 )x = 0

or, 4 - k/3 = 0/x

or, 4 - k/3 = 0

or, 4 = k/3

or, k = 4*3

:. k = 12 (Ans)

Answer:

$x = \frac{-3d-9}{k-d}$

Step-by-step explanation:

Step 1: Write out equation

d(-3 + x) = kx + 9

Step 2: Distribute d

-3d + dx = kx + 9

Step 3: Subtract 9 on both sides

-3d + dx - 9 = kx

Step 4: Subtract dx on both sides

-3d - 9 = kx - dx

Step 5: Factor out x

-3d - 9 = x(k - d)

Step 6: Divide both sides by k - d

$x = \frac{-3d-9}{k-d}$

Answer:

Question 3: $b \geq 2$

Question 4: $r < -5$

Question 5: $y \leq -6$

Step-by-step explanation:

Question 3:

$b + 2 \geq 4\\b + 2 -2 \geq 4 - 2\\b \geq 2\\$

Question 4:

$13 > 18 + r\\13 - 18 > 18 -18 + r\\\\-5 > r\\ r < -5$ sign flips when r switches sides

Question 5:

$3y \leq 2y - 6\\3y - 2y \leq 2y - 2y - 6\\\\y \leq - 6\\$
