Which equation represents the graphed function?

Answer:

it dropped 13 degrees

Step-by-step explanation:

Answer:

Base=3x-1

height =x

As we know that in a triangle

[tex]{\boxed{\sf Area={\dfrac {1}{2}}\times Base \times Height }}[/tex]

[tex]\qquad\quad {:}\longrightarrow\sf 22={\dfrac {1}{2}}(3x-1)(x)[/tex]

[tex]\qquad\quad {:}\longrightarrow\sf x (3x-1)=44 [/tex]

[tex]\qquad\quad {:}\longrightarrow\sf 3x^2-x=44 [/tex]

The equation that correctly shows the area of the triangle is 1/2x(3x - 1) = 22. Correct option is d.

To find the equation that correctly shows the area of the triangle, we use the formula for the area of a triangle:

Area = (1/2) * base * height

Given that the base is represented by 3x - 1 and the height is x, the area of the triangle is:

Area = (1/2) * (3x - 1) * x

Now, we are given that the area of the triangle is 22m^2:

(1/2) * (3x - 1) * x = 22

To solve for x, we can multiply both sides by 2 to eliminate the fraction:

2 * (1/2) * (3x - 1) * x = 2 * 22

x * (3x - 1) = 44

Now, we have the equation that correctly shows the area of the triangle:

x(3x - 1) = 44

So, the correct answer is:

x(3x - 1) = 44

Slope = [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Slope of a straight line passing two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the graph attached,

Line is passing through two points (20, 5) and (80, 20),

Therefore, slope of the line will be,

m = [tex]\frac{20-5}{80-20}[/tex]

m = [tex]\frac{1}{4}[/tex]

The slope is [tex]\frac{1}{4}[/tex].

Answer:

Correct Answer: (8,2)

Step-by-step explanation:

Dilation about the origin

Most dilations in the coordinate plane use the origin, (0,0), as the center of the dilation.

In such cases, every point (x,y) dilated by a factor of k is mapped to the point (kx,ky).

The point R=(4,1) is dilated by a scale factor of 2 (k=2), thus the coordinates of its image are (2*4,2*1) = (8,2)

Answer:

$15

Step-by-step explanation:

So first we see that alicia buys 3 books for $9 and that would be 27 because 3x9=27. Now we also see that she bought 2 magazines for $4 and that would be 8 because we are multiplying 4x2. Now we add 27 and 8 which would give us 35. She uses a $50 card to make the purchase. We subtract, 50-35 and we would get 15. So alicia has $15 left on the card.

Answer:

y=2x-5

Step-by-step explanation:

Answer and explanation is in the picture.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

The equation of the line that passes through the point (3, 1) and (1, -3) is

y = 2x - 5.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of a line is y = mx + c

(3, 1) = (a, b)

(1, -3) = (c, d)

Slope:

= (d - b) / (c - a)

= (-3 - 1) / (1 - 3)

= -4 / -2

= 2

m = 2

Now,

We can choose any point and set it as (x, y) and substitute it in the equation.

(3, 1) = (x, y)

y = mx + c

1 = 2 x 3 + c

1 = 6 + c

c = 1 - 6

c = -5

Now,

m = 2

c = -5

The equation of the line that passes through the point (3, 1) and (1, -3) is

y = 2x - 5.

Answer:

g = 12b /5

Step-by-step explanation:

Given that:

Quarts of green paint = 4

Cup of black paint = 5/3

Quartz of green paint to be mixed with a given proportion of black paint.

Let proportion of black paint = b

Quartz of green paint = g

4 quartz = 5/3 cups

g quartz = b

Cross multiply :

4 * b = (5/3) * g

5/3 * g = 4b

g = 4b ÷ 5/3

g = 4b * 3/5

g = 12b /5

The image of the point (0,1) after a rotation of 270^ ∘ counterclockwise about the origin is (-1, 0).

Let the point be having coordinates (x,y).

Case 1: If the point is in the first quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Case 2: If the point is in the second quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Case 3: If the point is in the third quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

For points on axes, it can take that point in any of the two surrounding quadrants. Since if the point is on the positive x-axis, then it can take as of the first quadrant or fourth quadrant.

There is no effect as we assumed rotation is concerning origin.

(0,1) ---- (-1, 0)

Hence, the image of the point (0,1) after a rotation of 270^ ∘ counterclockwise about the origin is (-1, 0).
