Answer:

d. x-axis

Step-by-step explanation:

Consider a point on curve P and its (nearest) image on curve P'. The midpoint between those points is on the line of reflection. That line is the x-axis.

_____

<em>Additional comment</em>

The curve is symmetrical about the y-axis, so each point on P also has an image point that is its reflection across the origin. The reflection of P could be across both the x- and y-axes, or (equivalently) across the origin. We don't know the meaning of "xy-axis", so we suspect that is a red herring. The best choice here is "x-axis."

Two numbers are in the ratio 7:9 if the sum of the number is 112 then the lrger number is?

nordsb [41]

Answer:

63

Step-by-step explanation:

the numbers are in ratio 7 : 9 = 7x : 9x ( x is a multiplier )

given the sum of the numbers = 112 , then

7x + 9x = 112 , that is

16x = 112 ( divide both sides by 16 )

x = 7 , then

9x = 9 × 7 = 63 ← value of larger number

In his motorboat, Bill Ruhberg travels upstream at top speed to his favorite fishing spot, a distance of 264 mi, in 6 hr. Re

Kobotan [32]

Answer:

The values are $x = 46 miles /hr$

$y = 4 \ miles / hr$

Step-by-step explanation:

From the question we are told that

The distance covered is d = 264 miles

The time taken is $t_1 = 6 hours$

The time taken for the return trip is $t_2 = 5.5 \ hours$

Generally during the trip toward fishing spot , the velocity is mathematically represented as

$v_t = \frac{d}{t_1 } = x - y$

=> $v_t = \frac{264}{6 } = x - y$

=> $x - y = 44 \cdots 1$

Generally during the return trip , the velocity is mathematically represented as

$v_r = \frac{d}{t_2} = x+ y$

=> $v_r = \frac{264}{5.5} = x+ y$

=> $48 = x+ y\cdots 2$

add equation 1 and 2

$2x = 92$

=> $x = 46 miles /hr$

substituting this into equation 1

$46 - y = 44 \cdots 1$

=> $y = 4 \ miles / hr$
