Answer:

Step-by-step explanation:

If the equations are true, they can be solved simultaneously.

Consider 2x-10y=-1 as Eq1 and 5x+6y=4 as Eq2

Multiplying Eq1 with 3 and Eq2 with 5 we get,

6x-30y=-3 -- Eq3 and 25x+30y=20 -- Eq4

Adding Eq3 and Eq4,

31x=17 Therefore, x=17/31

Plugin x=17/31 in Eq3,

6(17/31)-30y=-3 --- y=13/62

Plug In values of x and y in 7x-4y we get,

7(17/31)-4(13/62) = 3

So the value of 7x-4y = 3.

x = 3

Answer:

  (a) no

  (b) -1, (2, -1)

  (c) 4, (4, 7)

  (d) no

Step-by-step explanation:

You can check by using x=3 in the function.

  f(3) = 4(3) -9 = 12 -9 = 3 . . . . not -3

The point (3, -3) is not on the graph.

__

Put x=2 into the function and evaluate:

  f(2) = 4(2) -9 = 8 -9

  f(2) = -1

  The point (2, -1) is on the graph.

__

Put f(x) = 7 into the equation and solve for x.

  7 = 4x -9

  16 = 4x

  4 = x

  The point (4, 7) is on the graph.

Answer:

linear functions have no exponents higher than 1

Step-by-step explanation:

Answer:

  C.  {-1, 5, 8}

Step-by-step explanation:

Use each of the domain values in the function to see what the corresponding range value is.

  f(-1) = 5 -3(-1) = 8

  f(0) = 5 -3(0) = 5

  f(2) = 5 -3(2) = -1

The range is the set of numbers {-1, 5, 8}.

_____

Additional comment

The values in a set are generally listed lowest to highest. The coefficient of x in the equation for f(x) is negative, meaning the lowest range value will correspond to the highest domain value. If you start by finding f(2) = -1, you immediately eliminate all answer choices except B and C.

Those choices differ only in the middle value, so you can tell which is correct by evaluating f(x) for the middle domain value: f(0) = 5. Only one answer choice has both -1 and 5 in the set.

(There are two answers here: how you work the problem, and how you game a multiple choice question.)

Answer:

x > 10

Step-by-step explanation:

The B option is correct.

Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.

Given

A number is -906,060.

The equivalent number of the given number.

We know the number is -906,060.

It can be represented as [tex]\rm -906,060 = -9.0606 \ times\ 10^5[/tex].

Thus, the B option is correct.

The expressions for each area are:  28x²-35x ( rectangle ), 9x² ( square ) and 37x²-35x ( total area )

This exercise requires your knowledge about the area of compound shapes. For solving this, you should:

The figure is composed of a square and a rectangle. See the attached image.

Therefore, you should sum the area of these geometric figures for determining the area of the irregular figure.

Area of the rectangle = bh . The figure shows that the sides for this rectangle are equal to 4x-5 and (4x+3x). Then,

b= length of the base= 4x-5

h=height=4x+3x=7x

Thus,  A_rectangle=bh= (4x-5)*7x=28x²-35x

Area of the square= l². The figure shows that the sides for this square are equal to 3x

    l= length of the side= 3x

Thus,  A_square=l²= (3x)² =9x²

A_total= A_rectangle+A_square

A_total= 28x²-35x+9x²

A_total= 37x²-35x

The equation that allows us to find the value of N is 12N + 8 = 123.

Given that at a wedding reception, an equal number of guests were seated at each of 12 large tables, and 8 members of the wedding party were seated at the main table, and the total number of people at the reception, including the bride and groom , was 123, to determine what equation could you use to find the value of N if this letter represents the number of people at large tables, the following calculation must be performed:

Now, despite the fact that the problem is poorly formulated and the number N is not an integer, the equation that allows us to find the value of N is 12N + 8 = 123.

Rearrange the equation as

cos(x) - √(1 - 3 cos²x) = 0

cos(x) = √(1 - 3 cos²x)

Note that both sides have to be positive, since the square root function is non-negative. If we end up with any solutions that make cos(x) < 0, we must throw them out.

Take the square of both sides.

(cos(x))² = (√(1 - 3 cos²(x))²

cos²(x) = 1 - 3 cos²(x)

4 cos²(x) = 1

cos²(x) = 1/4

cos(x) = ± √(1/4)

cos(x) = ± 1/2

We throw out the negative case and we're left with

cos(x) = 1/2

This has general solution

x = arccos(1/2) + 360° n   or   x = -arccos(1/2) + 360° n

(where n is any integer)

x = 60° + 360° n   or   x = -60° + 360° n

Now just pick out the solutions that fall in the interval 0° ≤ x < 360°.

• From the first solution set, we have x = 60° when n = 0.

• From the second set, we have x = 300° when n = 1.

So the answer is D.

Step-by-step explanation:

Given that:

3(4x + 1) - 4x + 3 = -18

Multiply the number outside of the brackets with numbers on LHS.

⇛12x + 3 - 4x + 3 = -18

Shift variables on LHS and constant on RHS, changing it's sign

⇛12x - 4x = - 18 - 3 - 3

Subtract the values on LHS and RHS.

⇛8x = - 18 - 6

⇛8x = -24

Shift the number 8 from LHS to RHS.

⇛x = -24/8

Write the fraction in lowest form by cancelling method.

Therefore x = {-(24÷2)/(8÷2)}

= -12/4

= -3

Answer:

Hammer  cost 300 yen and screw cost 5 yen

Step-by-step explanation:

From given statement can be obtain

Hammer = h     &     screw = s

   Eq 1       4h + 10s = 1250 y

 Eq  2        2h + 40s = 800 y

 Multipyle eq 2 with 2

      2 (2h + 40s = 800) =2(800)

     ⇒  4h + 80s  = 1600      eq 3

Now minus eq 1 from eq 3

        4h + 80s = 1600y

        4h + 10s = 1250

         O  + 70s = 350y

             s = 350/70

     S = 5

To find hammer price put value of s in eq 1

     4h + 10s = 1250

     4 h = 1250 - 50 = 1200

   h = 1200/4 = 300

Answer:

x = 36

Step-by-step explanation:

Rearrange the equations before solving simultaneously

4y = -5x - 28

2y = 7x - 24

now subtract

4y - 2y = 2y

5x - 7x = -2x

-28 - - 24 = -4

put these values together.

2y - 2x - 4.

2y = 2x + 4

y = 2x + 4 / 2

y = x + 2

substitute this into one of the 1st equations in the question.

5x = -4(x + 2) + 28

5x = -4x + 8 + 28

5x = -4x + 36

9x = 36

x = 4.

Answer:

Think of combining like terms when subtracting polynomials. For example, 3x² and -2x². They both have x² in common. So, if you were to combine 3x² and -2x², it would be like 3x² + (-2x²). Think of this like 3 + (-2), which equals 1. In this case, it would equal 1x² or x².

Let's take this problem for example: 6x² - 3x + 4 - (-2x² +2x - 2)

Parentheses are super important; The first thing you want to do is distribute the negative sign out to everything inside the parentheses!

So,

6x² - 3x + 4 - (-2x² +2x - 2) *multiply the neg. to -2x², 2x, and -2

Now, if you do that, the equation would now look like:

6x² - 3x + 4 + 2x² - 2x + 2

Now think of combining like terms. Here are the like terms:

6x² - 3x + 4 + 2x² - 2x + 2 (Let's rewrite it to look like this...)

6x² + 2x² - 3x - 2x + 4 + 2

Let's combine the x²'s first, so... 6x² + 2x² = 8x²

Let's combine the x's, so... -3x - 2x = -5x

Let's combine the constants (numbers with no variable), so... 4 + 2 = 6

Your solution should be 8x² - 5x + 6
