Square = To the power (exponent) of two

4 times the number = Multiplication by 4

The number = unknown number = x

The two factors multiplied together to make a trinomial is (x-1)(3x-2).

Given equation is 3x²-5x+2.

An algebraic equation which of the second degree in x is known as quadratic equation. The quadratic equation in its standard form is ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.

In the given equation,

Multiply the first coefficient 3 with the last coefficient 2  so we get 2×3=6

Use any two numbers which on multiply give 6 and on adding or subtracting give -5.

Such two numbers are -2 and -3

On multiplying, (-3)×(-2)=6

On Adding, -3-2=-5

So, break -5x into -3x and -2x and we get

3x²-3x-2x+2

Taking out 3x common from the first two terms and -2 from the last two terms as

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

Taking out the common term (x-1) as common and get

(x-1)(3x-2)

Hence, the two factors of the equation 3x²-5x+2 that can be multiplied together to make this trinomial is (x-1)(3x-2).

The calculation of 129 ÷ 3.332 rounded to the appropriate number of significant digits is 39.

Given that;

129 ÷ 3.332

First we convert 3.332 to fraction

3.332 = 3.332/1

3.332 = 3.332/1 × 1000/1000 = 3332/1000

3.332 = 833/250

Hence we have;

129 ÷ 833/250

This can be written as

= 129 × 250/833

= 32250/833

= 38.71549 ≈ 39

By using the table, we see that the correct options are:

a) f(2) = 7

b) f(x) = 3 when x = 8.

c) f⁻¹(7) = 2

d) f⁻¹(x) = 8 when x = 3.

Here we have a table of x and f(x).

First, we want to find f(2). To get that, we need to go to the row where we have x = 2.

In that same row we can see that f(x) = 7.

Then f(2) = 7.

Then it says:

"if f(x) = 3, then x = ?"

This time we do the opposite. We find the row where f(x) = 3, and then we see the value of x in that row.

In the second row (counting from the bottom) we can see that when x = 8, f(x) = 3.

Then:

"if f(x) = 3, x = 8"

Then we want to get the inverse of f(x) evaluated in 7.

Here we use the rule:

[tex]f(x) = y\\f^{-1}(y) = x[/tex]

Then

[tex]f(2) = 7\\f^{-1}(7) = 2[/tex]

The answer here is 2.

Finally:

"if the inverse evaluated in x si 8, then what is the value of x"

Similar to before, we know that when we evaluate f(x) in 8, the outcome is 3.

Then when we evaluate the inverse in 3, the outcome is 8.

So here we must have x = 3.

Answer:

Step-by-step explanation:

The attached graph shows the graph opens downward, so the vertex at (-2, 6) is a maximum. The y-intercept is the constant, +2.

The range is the vertical extent of the function. Its upper limit is the maximum value of the function (6), and its lower limit is negative infinity.

  The range is {y l y ≤ 6}.

The graph opens downward, so it is increasing to the left of its maximum value, and decreasing to the right of its maximum. The x-coordinate of the maximum (-2) defines the upper limit of the increasing interval.

  The function is increasing over the interval (-∞, -2).

The y-intercept of the graph is where it crosses the y-axis. The value of x is zero there, so the value of the function is the value of its constant, +2.

  The function has a positive y-intercept.

Answer:

-1

Step-by-step explanation:

Simply plug in (-1) to both equations and add.

Equation 1:

2(-1)^2 = 2

3(-1) = -3

2 + -3 - 1 = -2

Equation 2:

-( - 1) = 1

Add both together:

-2 + 1 = -1

Answer:

The equation is 2x² + 3x - 1 and here f(x) is -1

Putting f(x) = -1.

[tex]f(x) = 2 {( - 1)}^{2} + 3( - 1) - 1[/tex]

[tex]f(x) = 2 (1) - 3 - 1[/tex]

[tex]f(x) = 2 - 3 - 1[/tex]

[tex]f(x) = - 1 - 1[/tex]

[tex]f(x) = - 2[/tex]

For g(x) put as -1

[tex]g(x) = - ( - 1)[/tex]

[tex]g(x) = 1[/tex]

Last step,

-2 + 1 = -1

Answer: W = 113/20

What we know:

Set up equation                                                W + 3/5 = 6 1/4

Expand                                                              W + 3/5 = 6*4+1 /4

Simplify                                                              W + 3/5 = 25/4

Common denominator                                     W + 3*4/5*4 = 25*5 / 4*5

Simplify                                                              W + 12/20 = 125/20

Subtract                                                                   -12/20    -12 /20

Solve                                                                  W = 113/20

Check:

By converting our answers into decimals, we can see if the sides are equal:

113/20 = 5.65

3/5 = 0.6

5.65 + 0.6 = 6.25

Does 6.25 = 6 1/4?

1/4 = 0.25

6 + 0.25 = 6.25

6.25 = 6.25

Therefore, W = 113/20 is the correct answer.

Answer:

Original Salary: [tex]5,957.14[/tex]

Increase in 3%: [tex]6,135.85[/tex]

Step-by-step explanation:

So when something increases by x%, the new value is (100+x)% the original value. So 6255, is 105% the original value. This means to find the original value, we have to find the number that has 6255 as 105% of it's value. Whenever you try to find x% of a number, you multiply it by the decimal value of the percentage, which is found by dividing by 100. So to find x%, you do: [tex]o*\frac{x}{100}[/tex] where o = original value, x=percent. In this case the percent is 105%, which when divided by 100 is 1.05. So this gives us the equation: [tex]o*1.05=6255 \implies o = \frac{6255}{1.05} = 5,957.14[/tex]. This is his original salary. You need to do this process, do not make the mistake of subtracting 5% from 6255. This is because 5% of 6255 does not equal the 5% of the original value. 5% of 6255 should be greater than 5% of the original value, since the new value is an increase of 5%. So since we have his original salary, we can calculate the salary increase had it been 3%. to do this we multiply by 1.03 (103% divided by 100). This gives us the equation: [tex]5,957.14*1.03=6,135.85[/tex]

Since:

Milk = 2% butter fat

Whipping cream = 30% butter fat.

This implies that  the milk contains the smallest of butter fat and it also implies that Otto would require  a lot more milk than cream, to be able to attain the 12% mixture.

This is known to be when point J is said to meet, and by using that data from point J, Otto require more of milk than the cream to get what he wants.
