Answer:

see explanation

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ), hence

F(- 1, 9) → F'(- 1, - 9)

G(- 2, 1) → G'(- 2, - 1)

H(- 7, 4) → H'(- 7, - 4)

Find the length of x

Goshia [24]

Answer:

x = 8 $\sqrt{2}$

Step-by-step explanation:

The triangle is isosceles with legs congruent, both x

Using Pythagoras identity in the right triangle

x² + x² = 16²

2x² = 256 ( divide both sides by 2 )

x² = 128 ( take the square root of both sides )

x = $\sqrt{128}$ = $\sqrt{64(2)}$ = $\sqrt{64}$ × $\sqrt{2}$ = 8 $\sqrt{2}$

Answer:

13.A) y= 4/3 x+1

D) all real numbers

Step-by-step explanation:

$y= -\frac{3}{4} x+2\\(3,5)=(x,y)\\m_1 =-\frac{3}{4} \\\\m_2 = \frac{-1}{-\frac{3}{4} } \\m_2 =4/3\\Substitute\:values\:into\:y=mx+b\:form\\\\5 = \frac{4}{3} (3) +b\\5 = 4+b\\5-4=b\\1=b\\m =4/3\\\\Substitute \:new\:values\:into\:y=mx+b\:form\\\\y = \frac{4}{3} x +1$
