what is the sign of f on the interval -5

Answer:

A´= (2, 3)

Step-by-step explanation:

Answer:

1) 1/2

2) 3

3)-5

Step-by-step explanation:

to find slope: divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. so here on 1) you do (3-2)/(2-0)= 1/2.

2) (7-1)/(-1- (-3))= 6/2=3.

3) (-15-0)/(7-4)= -15/3=-5

Answer:

x = 12

Step-by-step explanation:

130 + y = 180   {linear pair}

          y = 180 - 130

         y = 50°

3x - 6 +8x + 4 + 50 = 180        {Angle sum property of triangle}

3x + 8x - 6 +  4 + 50 = 180          {Combine like terms}

          11x + 48          = 180

                    11x        = 180 - 48

                          11x = 132

                            x = 132/11

x = 12°

Answer:

x = 12

Step-by-step explanation:

Reference angle = 45°

Opposite side length = x

Hypotenuse = 12√2

Thus, to find x, apply trigonometric ratio.

[tex] sin(45) = \frac{x}{12\sqrt{2}} [/tex]

Multiply both sides by 12√2

[tex] sin(45)*{12\sqrt{2}} = x [/tex]

[tex] \frac{1}{\sqrt{2}}*{12\sqrt{2}} = x [/tex] (sin 45 = 1/√2)

[tex] \frac{1*12\sqrt{2}}{\sqrt{2}} = x [/tex]

[tex] \frac{12\sqrt{2}}{\sqrt{2}} = x [/tex]

12 = x

x = 12

Answer:

3

Step-by-step explanation:

If the wire is in a square and all the sides are 5 inches when you unfold the wire it will be 20 inches long so if the length of the wire ina regtangle is 7 then the width is 3

Answer: 3.

Step-by-step explanation: The answer is 3 because the original shape was a square with all of the sides with the length 5. Because there are 4 sides in a square, the perimeter of the square is 20(5+5+5+5). Now, the square has been reshaped into a rectangle. If one of the side lengths of the rectangle is 7, the opposite and parrallel side has to be 7. 7+7 is 14. Now the expression is perimeter = 14 + 2(missing width). If you plug in 3, that expression is now 14+6, which is 20. Therefore, the missing side width is 3.

Answer:

Step-by-step explanation:

(3, 1) (6, -1)

(-1 -1)/(6-3) = -2/3

y - 1 = -2/3(x - 3)

y - 1 = -2/3x + 2

y = -2/3x + 3

Answer:

3

Step-by-step explanation:

The slope is 3 because when two lines are parallel, they have the same slope.

Answer:

Two lines that are parallel have the same slope. So in this case, the slope to the function parallel to f(x)= 3x+2 is equal to 3

Answer:

560 cubes

Step-by-step explanation:

Is 2 213 supposed to read 2 1/3? First calculate the volume of the box

V_box = 8/3 * 10/3 * 7/3 = 560/27 cubic inches

Now calculate the volume of your 1/3 inch cube:

V_cube = 1/3 * 1/3 * 1/3 = 1/27 cubic inches

Now divide the V_box by V_cube:

Number of boxes = (560/27) / (1/27) = (560/27) * (27/1) = 560 cubes

Answer:

3.428 or 3 wholes 3/7

Step-by-step explanation:

6 : 7 = n : 4 : 2

6 : 7 = n : 4

6/7 = n/4

7n = 24

n = 24 /7

n = 3. 428 or 3 wholes 3/7

Answer:

Its A) y=3/2x

Step-by-step explanation:

-3/2x would be the exact opposite of 3/2x it would be the same line but facing the left side because its on the negative side. And the others are not the same as 3/2x.

Sorry if i could not explain that well, but I am 99% sure its A, y=3/2x

Answer:

Louis reads faster

Step-by-step explanation:

See attachment for complete question.

The table represents Louis data while the graph represents Ricardo's data.

To solve this question, we simply calculate the slope of the table/graph,

The slope (m) is calculated by:

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

For Louis:

From the table, we pick any corresponding x and y values

[tex](x_1,y_1) = (2,436)[/tex]

[tex](x_2,y_2) = (6,1308)[/tex]

[tex]m_1 = \frac{1308 - 436}{6-2}[/tex]

[tex]m_1 = \frac{872}{4}[/tex]

[tex]m_1 = 218[/tex]

For Ricardo:

From the graph, we pick any corresponding x and y values

[tex](x_1,y_1) = (2,300)[/tex]

[tex](x_2,y_2) = (6,900)[/tex]

[tex]m_2 = \frac{900- 300}{6-2}[/tex]

[tex]m_2 = \frac{600}{4}[/tex]

[tex]m_2 = 150[/tex]

So, we have:

Louis: [tex]m_1 = 218[/tex]

Which means 218 words per minutes

Ricardo: [tex]m_2 = 150[/tex]

Which means 150 words per minutes

Answer:  The last expression shows the result of 3  so it models the distance between x and y.

Step-by-step explanation:

First you will have to  find the distance between the two points by square the x coordinates and squaring the y coordinates to find their sum .  

-4 - (-1) = -3

-5 - ( -5) = 0

-3^2 + 0^2 = d^2   where d  is the distance

9  = d^2

d= 3  

The distance is 3 units  

Now evaluate which expression have a solution as 3.

The last expression is the answer

the absolute value for -4 is 4   , and the absolute value for -1 is 1  and 4 minus 1 is 3.

Ensure to heart if this helps$

Answer:

3-1*1/4

3-1/4

12-1-(/4)

11/4

Step-by-step explanation:

Since N ≡ 0 (mod 2) and N ≡ 0 (mod 3),

N ≡ 0 (mod (2*3)) ≡ 0 (mod 6).

Hence when N is divided by 6,

the remainder is 0. (A)

Step-by-step explanation:

Answer:

24/9 or $2.67/year

Step-by-step explanation:

Answer:

An equation in the slope-intercept form is:

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where  m is the rate of change or slope and b is the y-intercept

Given

Given that every month Monica withdraws $15 from this account for her contact lenses

Given that after 3 months she has $255 left in her account.

i.e. (3, 255)

substituting [tex]m = 15[/tex], [tex]x = 3[/tex] and [tex]y = 255[/tex] in the slope-intercept form to determine the y-intercept

[tex]y = mx+b[/tex]

[tex]255 = 15(3) + b[/tex]

switch sides

[tex]15(3) + b = 255[/tex]

[tex]45 + b = 255[/tex]

[tex]b = 255 - 45[/tex]

[tex]b = 210[/tex]

Thus, the y-intercept b = 210

Now, substituting [tex]m = 15[/tex] and [tex]b = 210[/tex] in the slope-intercept form of the line equation

[tex]y = mx+b[/tex]

[tex]y = 15x+210[/tex]

Hence, an equation in the slope-intercept form is:

0.0002
