(-6,8); perpendicular to y = -3/2x -1

UNO [17]

Answer:

$y = \frac{2}{3} x + 12$

Step-by-step explanation:

$y = - \frac{3}{2} x - 1$

The gradient of a line is the coefficient of x when the equation of the line is written in the form of y=mx+c.

Thus, gradient of given line= $- \frac{3}{2}$ .

The product of the gradients of perpendicular lines is -1.

(Gradient of line)(-3/2)= -1

Gradient of line

$- 1 \div ( - \frac{3}{2} ) \\ = - 1( - \frac{2}{3} ) \\ = \frac{2}{3}$

Substitute m= $\frac{2}{3}$ into y=mx+c:

$y = \frac{2}{3} x + c$

To find the value of c, substitute a pair of coordinates.

When x= -6, y= 8,

$8 = \frac{2}{3} ( - 6) + c \\ \\ 8 = - 4 + c \\ c = 8 + 4 \\ c = 12$

Thus, the equation of the line is $y = \frac{2}{3} x + 12$ .

Find x (Geometry)<br> Full working out pls. Thank you

vichka [17]

in 1st figure

2:1=(x+2):2

2/1=(x+2)/2

4=x+2

x=2.

Similarly in the 2nd figure

8:5=(8+3):(5+x)

8/5 = 11/ (5+x)

8(5+x) =55

40+8x=55

8x=15

x=15/8

x=1.875

You would multiply 6 × 5 and you would get 30.

better explanation : solution would be A = B H = 6 × 5 which would give you 30ft²
