Solution :-

Here, we have been given that lines f and g are parallel. Thus, the angle measuring 135° and ∠2 are vertically opposite angles.

And we know that vertically opposite angles measure same. Thus,

∠2 = 135°

Hope that helps ~~~

Answer:

(a) $P" = (-4,-3)$

(b) $(x,y) \to (4,-8)$

Step-by-step explanation:

Given

$P = (4,3)$

Solving (a): Reflect across x and y-axis.

Reflection across x-axis has the following rules

$(x,y) \to (x,-y)$

So, we have:

$P' = (4,-3)$

Reflection across y-axis has the following rules

$(x,y) \to (-x,y)$

So, we have:

$P" = (-4,-3)$

Hence, the new point is: (-4,-3)

Solving (b): Rx . Do,2 (2,4)

$R_x \to$ reflect across the x-axis

Reflection across x-axis has the following rules

$(x,y) \to (x,-y)$

So, we have:

$(2,4) = (2,-4)$ ---- when P is reflected across the x-axis

$D_{o,2} \to$ dilate by a scale factor of 2

The rule is:

$(x,y) \to 2 * (x,y)$

So, we have

$(x,y) \to 2 * (2,-4)$

Open bracket

$(x,y) \to (4,-8)$

What is 2(x+5)<4+5x can i please get answer fast?

Korolek [52]

Answer:

x > 2

Step-by-step explanation:

2(x+5) = 2x + 10 -> 2x + 10 < 4+5x

Subtract 4 from each side.
2x +6 < 5x
Subtract 2x from each side
6 < 3x
2<x

So, x must be > 2

(7,5), (r,9) m=6 What is r?

Igoryamba

Answer:

The answer is that r = 7/6

Step-by-step explanation:

Given point: (7, 5)

Given slope: m = 6

Use the point slope form of the equation:

y - y1 = m(x - x1)

y - 5 = 6(x - 7)

y - 5 = 6x - 7

y = 6x + 2

Now, find r for the point (r, 9) by substitution:

9 = 6x + 2

6x + 2 = 9

6x = 7

x = 7/6

Proof:

y = 6x + 2

f(x) = 6x + 2

f(7/6) = 6(7/6) + 2

= 42/6 + 2

= 7 + 2 = 9, giving (7/6, 9). r = 7/6

Hope this helps! Have a great day!
