Use the line of best fit to determine the y-value when the x-value is 7.

A. 25
B. 37
C.53
D.42

Answer:

5:1

Step-by-step explanation:

n:1

25: 5

to get to five you multiple 1 by 5. You have to reverse the equation to n:1, so 25 divided by 5 is 5. So you'd answer would be 5:1 in the form of n:1.

Answer:

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

Step-by-step explanation:

Answer:

-2x + y + 5

Step-by-step explanation:

(5x - 2y + 1) - (7x - 3y - 4)

1) Distribute the negative sign and remove all parenthesis

5x - 2y + 1 - 7x + 3y + 4

2) Combine all like terms

-2x + y + 5

Answer:

x+(x+12)+(x-9)=180

3x+12-9=180

3x=180-3

3x=177

x=177/3

x=59

Each angle is 59°, 71° and 500°

Answer:

A simple exponential function to graph is y=2x . Notice that the graph has the x -axis as an asymptote on the left, and increases very fast on the right. Changing the base changes the shape of the graph. Replacing x with −x reflects the graph across the y -axis; replacing y with −y reflects it across the x -axis.

Answer:

The remaining tea = 0.305 kg

Step-by-step explanation:

The mass of Tea pack = 0.345 kg

The mass of tea taken = 40 g

as

Therefore, all we need is to subtract 0.04 kg from 0.345 kg to determine the tea left:

i.e.

Remaining Tea left = Total tea - Tea taken

                                = 0.345 - 0.04

                                = 0.305 kg

Therefore, the remaining tea = 0.305 kg

Answer:

1. 40-p+w

2. $4 left

I'm not sure about the first one, but I'm pretty sure about the second one.

619 is a prime number, so the fraction is in simplest form already.

Answer:

12

Step-by-step explanation:

2x (3) = 72 so 6x = 72 and so x = 12

Answer:12

Step-by-step explanation:

You divide 72 by 3 then that answer by 2 then you get 12. Then if you do 12•2 =24 Then 24 •3 it equals 72

Given that,

An equation : -9c² +2c +3 = 0

To find,

Find the value of x.

Solution,

We have, -9c² +2c +3 = 0

We can solve it using the formula as follows :

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Here, a = -9, b = 2 and c =3

Put the values,

[tex]c=\dfrac{-2\pm \sqrt{(2)^2-4(-9)(3)}}{2(-9)}\\\\c=\dfrac{-2+\sqrt{(2)^{2}-4(-9)(3)}}{2(-9)}, \dfrac{-2-\sqrt{(2)^{2}-4(-9)(3)}}{2(-9)}\\\\c=-0.47, 0.69[/tex]

So, the solution are -0.47 and 0.69.

Answer:

0.1538

Step-by-step explanation:

first convert 3/11 into a percentage

3÷11=0.272727272727273

0.272727272727273 × 100

27.272727272727/100

27.272727272727%

≈27.27%

27.27% of 22/39

change 22/39 into a decimal

22÷39=0.5641025641》0.564

27.27% of 0.564

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 27.27% * 0.564

Converting percent to decimal:

p = 27.27%/100 = 0.2727

Y = 0.2727 * 0.564

Y = 0.1538

Answer:

Step-by-step explanation:

3/11 of 22/39 is:

Answer:

-1

Step-by-step explanation:

A = (0,0)

B = (1,-1)

Slope = (-1-0)/(1-0) = -1/1 = -1

Step-by-step explanation:

Hey there!

Given;

The points is; (-1 , 2) and slope is 4.

Note: Use one-point formula.

[tex](y - y1) = m(x - x1)[/tex]

~ Put all values.

[tex](y - 2) = 4(x + 1)[/tex]

~ Simplify it.

[tex](y - 2) = 4x + 4[/tex]

[tex]4x - y + 6 = 0[/tex]

Therefore, the required equation is; 4x-y+6=0.

8.8 * 10^(-5)

0.000088

Step-by-step explanation:

(7.5 * 10^(-5)) + (1.3 * 10^(-5)) = 8.8 * 10^(-5)

8.8 * 10^(-5) = 0.000088

Answer:

No. A ticket can't be split into 1/2 ,Right?

Given:

Two end points of a line segment are (7,2) and (10,-5).

To find:

The gradient of the given line segment.

Solution:

We know that, gradient of a line segment is the slope of that line segment.

The end points of the line segment are (7,2) and (10,-5), so slope or gradient of the line segment is

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

[tex]m=\dfrac{-5-2}{10-7}[/tex]

[tex]m=\dfrac{-7}{3}[/tex]

Therefore, the gradient of the given line segment is [tex]\dfrac{-7}{3}[/tex].

Answer:

  400%

Step-by-step explanation:

Suppose sales in 1954 were 500. Then 80% of that amount is 400. A drop of 400 puts sales in 1955 at 500 -400 = 100.

The increase back to 500 in 1956 is an increase of 400 from a base of 100. As a percentage increase, that is ...

  400/100 × 100% = 400% . . . . increase from 1955 to 1956

Answer:

At school, the maximum number of students that can be in a class room is 22. There are 25 students signed up for the geometry class.

Therefore, there are (25-22)=3 extra students.

Hence, no more students can join the class.

Answer: 12 = x + 4

Step-by-step explanation:

We know that the length of the green line is 12.

And the length of the black line will be equal to the sum of the lengths of the two smaller segments, x, and 4

Then the length of the black line is x + 4

We want to write an equation that says that the length of the green line is equal to the length of the black line, this is:

Length of green line = Length of black line

12 = x + 4

That is the equation we wanted.

Now we could solve it if we subtract 4 in both sides of the equation:

12 - 4 = (x + 4) - 4

8 = x

      -6   -6

----------------

2a = 6

take six and divide by 2

a = 3

Answer:

3

Step-by-step explanation:

2a + 6 = 12

2a = 6 - 12

2a = 6

a = 6/2

= 3

1. The dictionary definition of a parallelogram is ...

  a quadrilateral with opposite sides parallel

As a consequence of this condition, a number of additional properties arise:

__

2. The dictionary definition of a trapezoid (US; trapezium, UK) is ...

  a quadrilateral with one pair of parallel sides.

As a consequence of this condition, it is not possible for a trapezoid to be a parallelogram.

3. A rhombus is a special case of parallelogram in which all sides are the same length. A square is a special case of rhombus in which all angles are congruent (as are the diagonals). Yes, a rhombus may be a square.

[tex]\displaystyle 2b.[/tex] A rhombus can never be a square because although opposite interiour angles and all four sides are congruent, their interiour angles are not right angles.
