Answer:

RS = 6

Step-by-step explanation:

RS² = SU*ST (secant-tangent rule)

Substitute

(x + 6)² = (x + 4 + 5)(x + 4)

(x + 6)(x + 6) = (x + 9)(x + 4)

x(x + 6) +6(x + 6) = x(x + 4) + 9(x + 4)

x² + 6x + 6x + 36 = x² + 4x + 9x + 36

x² + 12x + 36 = x² + 13x + 36

Collect like terms

x² - x² + 12x - 13x = -36 + 36

-x = 0

x = 0

✔️RS = x + 6

Plug in the value of x

RS = 0 + 6

RS = 6

Which equation shows y= −1/2x + 4 in standard form?

VladimirAG [237]

Y = -(1/2)x + 4

y + (1/2)x =4

(1/2)x + y = 4

Multiply both sides by 2

2*(1/2)x + 2*y = 2*4

x + 2y = 8

Option B.

Please answer question

sweet-ann [11.9K]

Given;

ABCDE is similar to VWXYZ

so, the corresponding segments are proportional

We need to find the length of XY

XY is corresponding to CD

CD = 1.2 cm

Finding another two corresponding sides

DE = 3.2 cm , YZ = 4 cm

so,

$\begin{gathered} \frac{XY}{CD}=\frac{YZ}{DE} \\ \\ \frac{XY}{1.2}=\frac{4}{3.2} \\ \\ XY=\frac{4}{3.2}\cdot1.2=1.5\operatorname{cm} \end{gathered}$

So, the length of XY = 1.5 cm

What is 25.5n - 3 = 5.5n + 10.

klemol [59]

N = 13/20 or 0.65

25.5n - 3 = 5.5n + 10

Add 3 to both sides of the equation.

25.5n = 5.5n + 13

Subtract 5.5n from both sides.

20n = 13

Divide both sides by 20.

n = 13/20 or 0.65
