Y= 6 + x

Plug the numbers into the equations, for each ordered pair substitute the first number (2) for x and the second number (8) for y...

Do the same thing with (6, 12) and if the number on each side of the equals sign is the same for both ordered pairs then you have the solution.
Hope that helps!

Solve for x: three halves plus one half times x equals two x
Masteriza [31]
I’m pretty sure it is 1 because if you have 3 half’s that equals 1 and 1/2 and then you add 1/2 which equals two so if you multiply it by X and it still equals two then X would have to be 1

The equation, y = 1250x + 22,850, gives the salary of a person as "y" after the stated number of years (x). Model the data with
Sidana [21]

Answer:

(a) y = 6250x +17850 --- The function

(b) y = 49100 --- The salary in 5 years

Step-by-step explanation:

Given

y = 1250x + 22850

Solving (a): Model the function around (1,24100) and (3,36600)

First, we calculate the slope

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{36600 - 24100}{3 - 1}

m = \frac{12500}{2}

m = 6250

The function is then calculated as:

y = m(x - x_1) + y_1

y = 6250(x - 1) + 24100

y = 6250x - 6250 + 24100

y = 6250x +17850

Solving (b): Salary in 5 years

Here:

x = 5

So:

y = 6250x +17850

y = 6250*5 +17850

y = 49100

Replace * with a number in such a way that the trinomial could be written in the form a(x+b)^2 or a(x-b)^2.
weqwewe [10]

Answer:

  • a) 6
  • b) 3.125 or 25/8

Step-by-step explanation:

a)

  • 1.5x² + 6x + * =
  • 1.5(x² + 4x + *) =
  • 1.5(x² + 2*2x + 4) =
  • 1.5(x + 2)²
  • * = 1.5*2² = 6

b)

  • 2x² - 5x + * =
  • 2(x² - 2.5x + *) =
  • 2(x² - 2*1.25x + 1.25²)=
  • 2(x - 1.25)²
  • * = 2*(1.25)² = 3.125  or 25/8

A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books. What is the probability
Gnesinka [82]

Answer:

Probability that one of them is mathematics and other two are either physics or history books = 0.51

Step-by-step explanation:

Given - A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books.

To find - What is the probability one of them is mathematics and other two are either physics or history books ?

Solution -

Given that,

A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books.

So,

Total number of books = 3 + 3 + 1 = 7

The student has to select 3 books

So, Total number of ways = ^{7} C_{3} = 35

So,

Probability that one of them is mathematics and other two are either physics or history books is -

= \frac{^{3} C_{1}. ^{4} C_{2}  }{^{7} C_{3}}

= \frac{(3)(6)}{35}

= \frac{18}{35}

= 0.51

⇒Probability that one of them is mathematics and other two are either physics or history books = 0.51
