Answer:

8

Step-by-step explanation:

Let the equation of the function represented by the table is,

y - y' = m(x - x')

Where m = slope of the line

(x', y') is a point lying on the line.

Since, slope of a line passing through (x_1,y_1) and (x_2,y_2) is,

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

Therefore, slope of a line passing through (18, 26) and (35, 43) is,

m = \frac{43-26}{35-18}

   = 1

Therefore, equation of the line passing through (18, 26) and slope 1 will be,

y - 26 = 1(x - 18)

y = x - 18 + 26

y = x + 8

Therefore, missing term of the equation is 8.

Is the function f(x) =(4)^x -2 an exponential function. If so, identify the base. If not, why not?
Ne4ueva [31]

Answer:

Yes.

Base: 4

Step-by-step explanation:

Since we have 4 to the power of x, we do indeed have an exponent. The -2 just signifies vertical movement down.

Find the product of (3x-4)(2x^2+2x-1)
lapo4ka [179]

Answer:

6x^3  - 2x^2  -11x +4

Step-by-step explanation:

(3x-4)(2x^2+2x-1)

Multiply 3x  by the second term

3x* (2x^2+2x-1)

 6x^3  +6x^2 -3x


Multiply -4  by the second term

-4*(2x^2+2x-1)

 -8x^2 -8x+4


Add these together,  lining up the terms

 6x^3  +6x^2 -3x  

            -8x^2 -8x+4

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

6x^3  - 2x^2  -11x +4

Give the following equation in point slopr form, what is the slope of the line?
AVprozaik [17]

Answer:

Slope= 3

Step-by-step explanation:

y - 4= 3(x+6)

y - 4= 3x + 18   distributive property

y - 4(+4) = 3x + 18(+4)  

cancel out the 4 with its oposite and apply to both sides.

y = 3x + 22   final answer

Remember the slope intersept equation... y=mx+b

m is slope

b means the y-intersept.

So the final slope of the line is 3. (demostrated by graph below)
