Easy question:
Two ends of a line have coordinates (-6,10) and (2,2). What are the coordinates of the midpoint of the line?

Answers

Answer 1

Answer:

midpoint = (-2 , 6)

Step-by-step explanation:

The midpoint can be found with the formula {(x1 + x2 )/2, (y1 + y2.) P1( x1 , y1 ), and P2 (x2 , y2 ) are the coordinates of two points, and the midpoint is a point lying equidistant and between these two points.

please show work 3d – 4 + d = 8d – (-12)

Answers

Answer:

d = -4

Step-by-step explanation:

3d – 4 + d = 8d – (-12)

3d - 4 + d = 8d + 12

4d - 4 = 8d + 12

(4d - 4d) - 4 = (8d - 4d) + 12

-4 = 4d + 12

-4 - 12 = 4d (+ 12 - 12)

-16 = 4d

-16/4 = 4d/4

d = -4

Answer:

d= -4

Step-by-step explanation:

3d- 4 +d = 8d + 12

4d - 4 = 8d + 12

4d = 8d + 16

-4d = 16

d= -4

Answer:

  (a)  y = 5

Step-by-step explanation:

The equation of a horizontal line can be written as ...

  y = constant

In order to make that line pass through a given point, the constant must match the y-coordinate of the point. Here, that is 5.

  y = 5

solve this equation by using the look inside method to rewrite the problem

Solve d=a+c/ac for a

Answers

Answer:

a=d(ac)-c

Step-by-step explanation:

Yes (multiply ac both sides subtract C both sides gets a alone)

Answer:

[tex]d = \frac{a + c}{ac} \\ [/tex]

multiply either sides by ac :

[tex](d \times ac) = ( \frac{a + c}{ac} ) \times ac \\ \\ dac = a + c[/tex]

collect a - terms together, by subtracting a from both sides:

[tex]dac - a = (a + c) - a \\ dac - a = c[/tex]

factorise out a :

[tex]a(dc - 1) = c \\ \\ { \boxed{ \boxed{a = \frac{c}{dc - 1} }}}[/tex]

f(x): -1

Step-by-step explanation:

Answer:

3/2, 1/2, - 1

Step-by-step explanation:

x + 2y = 1 --> this is 'f(x)'. Sub in the each x-value to the equations.

First part:

x = -2

x + 2y = 1

-2 + 2y = 1

2y = 3

y = 3/2

Second part:

x = 0

x + 2y = 1

0 + 2y = 1

2y = 1

y = 1/2

Third part:

x = 3

x + 2y = 1

3 + 2y = 1

2y = -2

y = -2/2

y = - 1

jim invested his savings in two investment funds. the amount he invested in fund A was $3000 less than the amount he invested in fund B. Fund A returned a 8% profit and Fund B returned a 7% profit. How much did he invest in Fund B, if the total profit from the two funds together was $960?

Answers

Answer:

$8000

Step-by-step explanation:

Let it be that investment in A is x dollars, then Jim invested in B x+3000.

x/100*8=0.08x- the profit from A, (x+3000)/100*7= 0.07x+210

0.08x+0.07x+210=960

0.15x=750

x=750/0.15= 5000

5000+3000=8000dollars- investment in B

The required amount invested in Fund A is $5000, and in Fund B is $8000.

What are simultaneous linear equations?

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
Let the amount invested in fund A be x, and the amount invested in fund b be y.
x  = y - 3000 - - - - - -  - - - - -(1)

0.08x + 0.07y = 960 - - - - - - - - (2)

From the equation, 1
[y - 3000]0.08 + 0.07y = 960
y = $8000

Now,
x = 8000 - 3000
x = 5000

Thus, the required amount invested in Fund A is $5000, and in Fund B is $8000.

The correct option is (a) i.e. Regression equations are usually used to predict values of unavailable data. If the data do not closely model a particular type of function, then that type of function is not appropriate to use in statistical regression. The more closely data fit a model, the more accurate predicted values will be.

What is Regression analysis?

A collection of statistical techniques known as regression analysis is used to estimate the associations between a dependent variable and one or more independent variables. It can be used to simulate the long-term link between variables and gauge how strongly the relationships between them are related.

Although there are non-linear regression techniques for more complex data and analysis, simple linear regression and multiple linear regression are the two fundamental types of regression. While multiple linear regression employs two or more independent factors to predict the outcome, simple linear regression just uses one independent variable to explain or predict the outcome of the dependent variable Y. (while holding all others constant).

Professionals in other industries, including banking and investment, might benefit from regression. Regression can also aid in predicting sales for a business based on external factors like the weather, past sales, GDP growth, and other variables. A popular regression model in finance for valuing assets and calculating capital expenses is the capital asset pricing model (CAPM).

We can think of a similar problem involving [tex]8 \div 4[/tex] which could answer the question "if she has 8 cups and pours 4 cups per glass, then how many glasses can she fill?" (that answer being 2 glasses).
