Step-by-step explanation:

y = -1.5x + 3 is the equation of the line

The general form of the equation of a line is y = mx + b,

where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).

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

From the graph: x1 = 0, y1 =3 and x2 = 2, y2 = 0

m = (0-3)/(2-0) = -3/2 = -1.5

From the graph: b = 3

Therefore, the equation of the line is y = -1.5x + 3

Answer:

The tides change as the three interact.

Step-by-step explanation:

When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides—both commonly called spring tides.

Answer:

y = -x + 9

Step-by-step explanation:

The line that passes through the points (-2,4) and (0,6) has a slope of 1, and a y intercept of 6. The equation to the first line is y = x + 6. and perpendicular lines always have the opposite, reciprocal slope of the other line. So the slope for the second line would be -1. A line with the slope of -1 and a point of (5,4) would contain the points (5,4) , (4,5) , (3,6) , (2,7) , (1,8) , and (0,9) , which is the y intercept for the second line. So the equation for the second line would be y = -x + 9

The error is the sign of Inequality.

For Inequality, when the variable has negative coefficient, moving to another side would cause the Inequality symbol/sign to swap.

Here we need to learn how to read a graph.

In a normal graph we have the inputs (the values of x) in the horizontal axis and the outputs in the vertical axis.

Here we want to see what is the value of y for the blue graph when x = 2.5

We will find y = -1.5

(the blue graph is the one that corresponds to: y = x^2 - 2x - 3)

To find this:

The first thing we need to do is find x = 2.5 in the horizontal axis.

Now that we found it, we need to draw a vertical line, and see at which point of the blue graph this vertical line intersects the curve. At that point we draw an horizontal line that intercepts the vertical axis.

At that point we have the y-value

You can see an example of this, a good estimation by only looking at the graph is y = -1.5

For the other point, the value of x when y = 1.

We do exactly the same thing but in the inverse order, we first find y = 1

Then we draw an horizontal line that intercepts the graph

Then we draw a vertical line that intercepts the x-axis and we find the value.

We can see that for y = 1 we have x = 3.2 aprox.

Each dog will receive 1/32 pounds of dog treat.

Unitary method is first obtaining the value of a single unit then deriving the given unit from it by multiplying it.

Suppose in 1 hour a car can go 50 miles,So in 3 hours it will go to (3×50) = 150 miles.

According to the given question a pet store owner has a 1/2 -pound bag of dog treats that she divides evenly among 16 dogs.

∴ Each dog will receive (1/2)/16 pounds of dog treat which is

Answer: 3

Step-by-step explanation:

1. 2²=4

2. 4*5=20

3. 180/20=9

4. √9=3

Hope this helped :)

Answer:

x = 3

Choice 2

Step-by-step explanation:

180 = 2^2 * x^2 * 5

180 = 20x^2

9 = x^2

x = 3

Checking:

180 = 2^2 * 8^2 * 5

180 = 4 * 9 * 5

180 = 36 * 5

180 = 180

Answer:

(7 , 5)

Step-by-step explanation:

Add all the x-axis then divide by 3

7 + 3 + 11 = 21

21/3 = 7

Add all the y-axis then divide by 3

9 + 3 + 3 = 15

15/3 = 5

The coordinates of the centroid of triangle ABC.

(x, y)

Where,

x = Sum all the x-coordinates of the vertices ÷ 3

y = Sum o

The coordinates of the centroid is (7, 5).

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

The vertices of the triangle in the diagram below are:

A(7,9), B(3,3), and C(11,3).

Now,

The coordinates of the centroid of triangle ABC.

(x, y)

Where,

x = Sum all the x-coordinates of the vertices ÷ 3

y = Sum of the y-coordinates of the vertices ÷ 3

Now,

x = 7 + 3 + 11 / 3 = 21/3 = 7

y = 9 + 3 + 3 / 3 = 15/3 = 5

Now,

The coordinates of the centroid is (7, 5).

Final Answer: [tex]x = 38[/tex]

Steps/Reasons/Explanation:

Question: What is the value of x in the equation [tex]3(x + 10) = 4(x - 2)[/tex]?

Step 1: Expand.

[tex]3x + 30 = 4x - 8[/tex]

Step 2: Subtract [tex]3x[/tex] from both sides.

[tex]30 = 4x - 8 - 3x[/tex]

Step 3: Simplify [tex]4x - 8 - 3x[/tex] to [tex]x - 8[/tex].

[tex]30 = x - 8[/tex]

Step 4: Add [tex]8[/tex] to both sides.

[tex]30 + 8 = x[/tex]

Step 5: Simplify [tex]30 + 8[/tex] to [tex]38[/tex].
