Answer:

Step-by-step explanation:

U find the gradient of the line by subtracting the y intercepts and the x intercepts

4-3/1--2=1/3

Y-3/x--2=1/3

3(y-3)=x+2

3y-9=x+2

3y=x+2+9

3y=x+11

Y=x/3 + 11/3

Hii can someone help with this pls :)

Answer:

$R(x,y) = (0.8,-1.2)$

Step-by-step explanation:

The coordinates of QS are:

$Q(x_1,y_1) = (-2,-6)$

$S(x_2,y_2) = (5,6)$

The ratio is represented as:

$R_{m:n} = 2:3$

Required

Find the coordinates of R

The coordinates of R is calculated by:

$R(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})$

Substitute values for m, n, x's and y's

$R(x,y) = (\frac{2 * 5 + 3 * -2}{2+3},\frac{2*6 + 3*-6}{2+3})$

$R(x,y) = (\frac{4}{5},\frac{-6}{5})$

$R(x,y) = (0.8,-1.2)$

Please help 49÷k –3=46

Andreas93 [3]

$\frac{49}{k} -3 = 46$
$\frac{49}{k} = 49$ . . . . add 3
$\frac{49}{49} = k$ . . . . multiply by $\frac{k}{49}$

k = 1

Solve for x y=c(x+b)

sergeinik [125]

Step-by-step explanation: To solve for x in this literal equation, I would first distribute the C through the parentheses to get y = cx + cb.

Now subtract cb from both sides to get y - cb = cx.

Finally, divide both sides by c to get y - cb / c = x.
