which of these tables represents a linear function?​

Answer:

Answer is b or 10.

Step-by-step explanation:

The reason for this is that you will just plug in all the answers in x and the answer has to match 15.

So...

2(10) - 5 = 15

15 = 15

This is true so the answer is 10.

Answer:

If a is positive and c is negative, there will be 2 real numbers solutions

Step-by-step explanation:

To get this, we need to get the value of the discriminant

Mathematically;

D = b^2 - 4ac

In this case , since a is positive and c is negative;

Then b^2 - 4ac will be positive

Thus b^2 - 4ac will be greater than zero

If the discriminant D is greater than zero, then we should expect 2 real-number solutions

Answer:$71.50

Step-by-step explanation:

Hello!

So first you want to find out how many bottles of soap you can make

To do that you want to divide how many ounces you have by how many ounces it takes to make 1 bottle

97.5 / 7.5 = 13

So you know you can make 13 bottles of soap

So now you want to multiply the number of bottles of soap that can be made by the amount of money you can make per bottle

13 * 5.50 = 71.50

So you know that the students can make $71.50

Answer:

If f(x)=g(x), the solution is x=-2

Step-by-step explanation:

We are given:

[tex]f(x)=3x+3\\g(x)= (-1/2)x-4[/tex]

We need to find the solution if f(x)=g(x)

Now solving for f(x)=g(x)

[tex]f(x)=g(x)\\3x+3=(-\frac{1}{2}x)-4\\3x+3=-\frac{1}{2}x-4\\3x+\frac{1}{2}x=-4-3\\\frac{3x*2+x}{2}=-7\\\frac{6x+x}{2}=-7\\\frac{7x}{2}=-7\\x=-7*\frac{2}{7}\\x=-2[/tex]

If f(x)=g(x), the solution is x=-2

The answer is 1

Step-by-step explanation:

14 = 2 × 7

51 = 3 × 17

21 = 3 × 7

Answer: W = 112 carats

Step-by-step explanation: Let W be the original weight.

So we have

W - 45 = 67 add 45 to both sides

And that equals 112 carats

Answer:

Y=-15/2x

Step-by-step explanation:

The equation of line in the form y=mx is y=-15/2x

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given coordinates:

(2, -15) and​ (6, -45).

Now, slope for the equation

slope= [tex](y_2 - y_1)/ (x_2- x_1)[/tex]

slope= (-45 - (-15))/ (6 - 2)

slope= (-45 + 15)/ 4

slope= -30/4

slope= -15/2

Hence, the equation of line in the form y=mx is y=-15/2x

The range of values for x would be 6 < x < 8.

"It  is a ray/line that divides an angle into two equal parts."

From figure,

BD is perpendicular to the base AC.

Since BD is an angle bisector,

⇒ 4x - 8 = 20

⇒ 4x = 20 + 8

⇒ 4x = 28

⇒ x = 28/4

⇒ x = 7

Therefore, the range of the values for x would be,

6 < x < 8.

Answer:

4.8

Step-by-step explanation:

Answer and explanation:

This is an example of negative correlation/inverse relationship between two variables. A negative correlation between two variables, independent and dependent variable, occurs when increase in one variable is associated with decrease in the other. In other words, the two variables tend to go in opposite direction.

The independent variable is the variable that causes a change in the dependent variable. For example, an increase in the independent variable in an inverse relationship will bring about a decrease in the dependent variable.

A good real world example is the increase in inflation and the decrease in purchasing power of money.

An equation for this could be

Y=-0.2(x)

Where y is dependent variable purchasing power and x is independent variable inflation

Answer:

B. 14,000

I hope that this helps you, have a wonderful day!

The best estimate from the option is 14,000 since 14,000 is the nearest value from the option to 12763.

Given,

18 x 709

We need to find the best estimate.

We need to multiply each number of one number with the other number and add them to get the product.

Example:

21 x 34 =

21 x 3 = 63

21 x 4 = 84

    2 1

x  3 4

    84

+ 63    

  71 4

We have,

18 x 709

We can write it as:

709 x 18

709 x 8 = 5672

709 x 1 = 709

             709

            x  18

           5672

     +   709  

          12762

Thus the best estimate from the option is 14,000 since 14,000 is the nearest value from the option to 12763.

Answer:

see explanation

Step-by-step explanation:

x² + 3x + 7 = 5 ( subtract 5 from both sides )

x² + 3x + 2 = 0 ← in standard form

(x + 2)(x + 1) = 0 ← in factored form

Equate each factor to zero and solve for x ( zero product rule )

x + 2 = 0 → x = - 2

x + 1 = 0 ⇒ x = - 1

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

x² - 2 = - 2x² + 5x ( subtract - 2x² + 5x from both sides )

3x² - 5x - 2 = 0 ← in standard form

(3x + 1)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

3x + 1 = 0 ⇒ 3x = - 1 ⇒ x = - [tex]\frac{1}{3}[/tex]

x - 2 = 0 ⇒ x = 2

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

(x + 3)² + 4x = 0 ← expand left side using FOIL and simplify

x² + 6x + 9 + 4x = 0

x² + 10x + 9 = 0 ← in standard form

(x + 9)(x + 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 9 = 0 ⇒ x = - 9

x + 1 = 0 ⇒ x = - 1
