Answer:

(5,4) and (3,4)

Step-by-step explanation:

A line segment has 2 end points which can be denoted as:

[tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

When this line segment intersects at y.

This means that the coordinate on the y axis is the same at both end points

i.e.

[tex]y_1 = y_2 = y[/tex]

[tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] becomes [tex](x_1,y)[/tex] and [tex](x_2,y)[/tex]

x1 and x2 can be any value but the y value must remain unchanged

Using the above analysis, a possible coordinate is:

[tex](5,4)[/tex] and [tex](3,4)[/tex]

Note that there are as many answers as possible as long as the coordinate pair satisfy is of the form [tex](x_1,y)[/tex] and [tex](x_2,y)[/tex]

Take for instance, another possible pair is:

[tex](1,-3)[/tex] and [tex](0,-3)[/tex]

Answer: x = -7 and x = 2

(x,y)

look at the 2 that y=1

Using the graph the input values that correspond with f(x) = 1 is x = -7 and x = 2.

A graph is a visual representation of data or information, often used to show the relationship between variables.

The given graph is of a function f(x) which is shown on the y-axis. The horizontal line at y = 1 is also shown on the graph.

To find the input values that correspond with f(x) = 1, we need to look for the points where the function f(x) intersects with the horizontal line y = 1.

From the graph, we can see that there are two such points:

One point is where the function intersects the line at x = -7. At this point, f(x) = 1, since the function value is equal to the y-coordinate of the intersection point.

The other point is where the function intersects the line at x = 2. At this point, f(x) = 1 as well.

Therefore, the input values that correspond with f(x) = 1 are x = -7 and x = 2. So the answer is "x = -7 and x = 2".

Step-by-step explanation:

Follow the formula: (y2 - y1) / (x2 - x1). So 4-(-4) and 2-(-2). A negative and a negative equal a positive so 8/4. Then simplify. Which gives you 2/1. Hope this helps.

Answer: 2 inches in width

Step-by-step explanation:

4 - 6

divide both by 2

2 - 3

The width of a similar photo comes to be 2 inches.

Width of original photo = 4 inches

Height of the original photo = 6 inches

Height of the scaled photo = 3 inches

A scale factor is a number that multiplies (“scales”) a quantity.

Scale factor = height of scaled photo/ height of the original photo

Scale factor= 3/6 = 1/2

So, the width of the scaled photo = scale factor * width of the original photo

The width of the scaled photo = (1/2)*4

The width of the scaled photo =2 inches.

Therefore, the width of a similar photo comes to be 2 inches.

Answer:

x = 7 (i think..)

Step-by-step explanation:

-3 (4 - 3x) = 5x + 16

* multiple -3 to each number in the parenthesis

-12 + 9x = 5x + 16

* add 12 to both sides to cancel it and combine like terms on the other side

9x = 5x + 28

* subtract 5x from both sides to cancel it out and combine like terms

4x = 28

* divide 4 from both sides to get x alone

x = 7

Answer: C. about 3%

Step-by-step explanation:

In 2006 , Number of dogs in U.S. dogs  = 72 million

In 2010, Number of dogs in U.S. dogs  = 70 million

The percent decrease in the number of dogs in U.S. Homes from 2006 to 2010  =

[tex]\dfrac{\text{Change in number of dogs}}{\text{Number of dogs in 2006}}\times100\%\\\\=\dfrac{(72-70)\text{ million}}{70\text{ million}}\times100\%\\\\=\dfrac{2}{7}\times10\%\approx3\%[/tex]

So, the percent decrease in the number of dogs in U.S. Homes from 2006 to 2010 was about 3%.

Hence, the correct option is C. about 3%

Answer:

The correct option is C: the isotope of iodine contains 81 neutrons.

Step-by-step explanation:

The mass (A) of the iodine isotope is given by:

[tex]A = Z + N[/tex]

Where:

Z: is the number of protons

N: is the number of neutrons

For iodine Z= 53, so if A = 134 the number of neutrons is:

[tex] N = A - Z = 134 - 53 = 81 [/tex]

Therefore, the correct option is C. The isotope of iodine contains 81 neutrons.

Step-by-step explanation:

Here, we want to find the slope of the line

We use the slope equation

m = (y2-y1)/(x2-x1)

m = (35-70)/(25-50) = -35/-25 = 7/5

what it means is that the rate of change of the number of red drops to number of blue drops to form the purple color is in the ratio of 7 to 5

Answer:

The directional bearing of the boat is N 30º E

Step-by-step explanation:

Let [tex]\vec v = (25, 25\sqrt{3})[/tex], where [tex]\vec v[/tex] is the vector velocity. Given that such vector is represented in rectangular, a positive value in the first component is the value of the vector in the east direction, whereas a positive value in the second component is in the north direction. The directional bearing of the boat ([tex]\theta[/tex]), measured in sexagesimal degrees, is determined by trigonometrical means:

[tex]\theta = \tan^{-1}\frac{v_{y}}{v_{x}}[/tex] (1)

If we know that [tex]v_{x} = 25[/tex] and [tex]v_{y} = 25\sqrt{3}[/tex], then the directional bearing of the boat is:

[tex]\theta = \tan^{-1} \sqrt{3}[/tex]

[tex]\theta = 60^{\circ}[/tex]

In consequence, we conclude that the direction bearing of the boat is 30 degrees to the East from the North (N 30º E).

Answer:

y=4x-3

Step-by-step explanation:

We're given that the equation is linear (a line), so it must be in the form y=mx+b. We're also given that it contains the points (0,-3) and (1,1).

Plugging the values of the x and y coordinates in that first point, we get the equation -3=m*0+b, simplifying to -3=b. Therefore, the b-value is -3.

Next, we can plug in the values from the second point to get the equation 1=m*1-3, which simplifies to 1=m-3. Adding 3 to both sides, we get m=4. Therefore, the equation of the line is y=4x-3.

Note that -3 is the value where the line intercepts the y-axis, which means -3 is known as the y-intercept. The value of b is always the y-intercept.
