What ordered pair is a solution to y=x+5 and x-5y=-9

Parallel lines are lines that are always the same distance apart and will never intersect. Intersecting lines are lines that cross or meet at a point. Perpendicular lines are lines that intersect at a right angle (90 degrees).

To determine if lines are parallel, you can look at their slopes. If two lines have the same slope, they are parallel. For example, the lines y = 2x + 3 and y = 2x - 5 are parallel because they both have a slope of 2.

To determine if lines are intersecting, you can look at their slopes and y-intercepts. If two lines have different slopes, they will intersect at some point. For example, the lines y = 2x + 3 and y = -x + 7 are intersecting because they have different slopes (2 and -1, respectively).

To determine if lines are perpendicular, you can look at their slopes. If the product of the slopes of two lines is -1, they are perpendicular. For example, the lines y = 2x + 3 and y = -0.5x + 7 are perpendicular because the product of their slopes (2 and -0.5) is -1.

The value of 12.5 kg into lbs can be converted by multiplying kilogram by 2.204622  so the answer is 27.55 pounds.

Unit conversion is the process of converting the measurement of a given amount between various units, often by multiplicative conversion factors that alter the value of the measured quantity without altering its effects.

The SI unit of mass is the kilogramme (kg). It has the same mass as the international kilogramme prototype. The International Bureau of Weights and Measures maintains a platinum-iridium international prototype similar to this one. A kilogramme is about equivalent to 2.20462262184878 pounds.

The legal definition of a pound, or the international avoirdupois pound, is 0.45359237 kilogrammes.

Pounds = kilograms × 2.20462262184878

= 12.5 x 2.20462262184878

The requried area of the larger triangle is 81 cm².

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not greater than 180°.

Here,
When two triangles are similar, the ratio of their corresponding sides is the same, and the ratio of their areas is equal to the square of this side ratio.

In this case, the ratio of the sides of the larger triangle to the sides of the smaller triangle is 3/2 (since it is given that the ratio of the sides is 2:3). Therefore, the ratio of the areas of the larger triangle to the area of the smaller triangle is (3/2)² = 9/4.

Given that the area of the smaller triangle is 36 cm^2, we can use the area ratio to find the area of the larger triangle:

Area of larger triangle = (9/4) × (Area of smaller triangle)

= (9/4) × 36 cm²

= 81 cm²

The function that can be graphed is option (d) f(x) = √(x + 1) + 8

Functions are commonly used in mathematics to describe relationships between variables.

To determine which of the four functions could be graphed, we first need to identify the curve's intercepts and asymptotes.

From the graph, we can identify the intercepts as (0,8) and (–3,0). The asymptotes are given by the equations x = 0 and y = 8. We can then use these points to compare the given functions and determine which one could be used to graph the curve.

Of the four functions, only f(x) = √(x + 1) + 8 fits the given description. This function has intercepts at (0,8) and (–3,0) and asymptotes at x = 0 and y = 8. Thus, f(x) = √(x + 1) + 8 is the function that could be graphed

Step-by-step explanation:

Applying the inscribed angle theorem, the measure of arc WX is: 126°.

An inscribed angle is an angle that is created by two chords intersecting on the outer edge of a circle.

If two inscribed angles are formed by the same arc, then they have the same degree measurement, according to the inscribed angle theorem. The theorem also states that the measure of the inscribed angle is half of the measure of the intercepted arc.

Angles WVX and WYX are inscribed angles that are subtended by the same arc WX. Therefore:

m<WVX = m<WYX

Substitute:

11x - 3 = 8x + 15

Solve for x:

11x - 8x = 3 + 15

3x = 18

3x/3 = 18/3

x = 6

m<WVX = 1/2(m(WX))

Substitute:

11x - 3 = 1/2(m(WX))

2(11x - 3) = m(WX)

22x - 6 = m(WX)

m(WX) = 22x - 6

Plug in the value of x:

m(WX) = 22(6) - 6

It should take Danielle 4 hours, or 240 minutes (since 1 hour = 60 minutes), to be 12 miles ahead of David.

What is the relative velocity?

Relative velocity is the velocityof an object or a person with respect to another object or person. It is the rate at which one object is moving with respect to another object. In other words, relative velocityis the speed at which an object is moving relative to a reference point.

To answer this question, we can use the formula:

time = distance / relative speed

Here, we need to find the time it takes for Danielle to be 12 miles ahead of David. Let's assume that t is the time in hours it takes for Danielle to be 12 miles ahead of David.

During this time, Danielle would have covered 12 more miles than David. Therefore, the distance between Danielle and David will be 12 miles.

Relative speed between them can be calculated by subtracting David's speed from Danielle's speed, since they are running in the same direction. So, relative speed will be:

relative speed = Danielle's speed - David's speed

= 7 - 4

= 3 miles per hour

Now, we can substitute the values of distance and relative speed in the formula to find the time it takes for Danielle to be 12 miles ahead of David:

time = distance / relative speed

= 12 miles / (3 miles per hour)

= 4 hours

Hence, it should take Danielle 4 hours, or 240 minutes (since 1 hour = 60 minutes), to be 12 miles ahead of David.

Answer: If there are 12 identically matched points on the picture of the sun, then the angle between any two adjacent points is 360/12 = 30 degrees.

When you line up two suns directly on top of each other, all of the matched points on the top sun will line up with the corresponding matched points on the bottom sun.

To find the least number of degrees that you can rotate the top sun so that the two suns are perfectly aligned again, you need to find the smallest angle that is a multiple of 30 degrees.

The smallest angle that is a multiple of 30 degrees is 360 degrees, which is equivalent to rotating the top sun all the way around once. Therefore, the least number of degrees that you can rotate the top sun so that the two suns are perfectly aligned again is 360 degrees.

Answer: the answer is C

Step-by-step explanation:

To make the systems equivalent, we need to multiply both sides of each equation in the first system by the same constant in order to get the corresponding equations in the second system.

If we multiply the first equation in the first system by 4, we get:

16x + 20y = -12

If we multiply the second equation in the first system by -4, we get:

-20x + 12y = 52

Comparing this to the second system, we see that the equation -20x + 12y = 52 matches the second equation in the second system. Therefore, the value of C in the second system must be 52.

So, the answer is C.

The temperature at half past eleven would be 2 °C.

In mathematics, an algebraic expression is an expression built up from constant algebraic numbers, variables, and the algebraic operations.

Given is that the temperature in Austria one morning was -5 degrees Celsius at eight o clock and increased by 2 degrees Celsius every hour until twelve o clock.

We can write the temperature variation as a function of hour {x} as -

T{x} = (- 5 + 2{x})°C

For half past eleven, we will have -

{x} = 3.5

When its input is changed to its negative, the output of an even function remains intact.

An odd function is one whose output changes sign when its parameter is made negative.

We may plot a function and examine its graph to determine if it is even or odd. The function is an even function if the graph is symmetrical around the origin (x=0, y=0). The function is an odd function if the graph is symmetrical around the y-axis (x=0).

The area of the shaded region that is the segment of the circle is equal to 4.6 ft² to the nearest tenth.

To calculate the area of a segment of a circle, you need to know the radius of the circle, the central angle of the segment (in radians or degrees), and possibly the height of the segment (the distance from the chord of the segment to the center of the circle).

The formula for the area of a segment of a circle is:

A = θ/360° × πr² - 1/2 × r² × sinθ

where A is the area of the segment, r is the radius of the circle, and θ is the central angle of the segment in degrees.

From the question;

the central angle = 90°

radius r = 4ft

Area of the segment = 90°/360° × π4² - 1/2 × 4² × sin90°

Area of the segment = 1/4 × π × 4 × 4 - 1/2 × 4 × 4 × 1 {sin90° = 1}
