I would guess 61 in my school we only do things like this x4 - 5 x times four minus five so I don’t know if that’s right but that would be my guess if that isn’t right it would be 62 times 2

Multiply the following polynomial and write the resulting polynomial in descending order. (3x-8)(2x^2+4x-9)

Step2247 [10]

$(3x-8)(2x^2+4x-9)=6x^3+12x^2-27x-16x^2-32x+72=6x^3-4x^2-59x+72$

Value of the coefficient of the $x^3$ term is $\boxed{6}$

Value of the coefficient of the $x^2$ term is $\boxed{-4}$

Value of the coefficient of the x term is $\boxed{-59}$

The value of the constant is $\boxed{72}$

b) After adding the 0 test score, the mean would be affected-----> is true

c) After adding the 0 test score, the median would be the most appropriate measure of center to describe the data-----> is false

d) Before the missed test, Eva’s median score was 96-----> is false

e) Before the missed test, Eva’s median score was 91------ is true

Whats the output when the input is 1234n and the output is 10 12 14 16.

Grace [21]

Answer:

y=2x+8

Step-by-step explanation:

Alright so, to find the equation, we need to find the slope first. We can do that by turning the input and output into coordinates.

(1,10) and (2,12)

To find the slope, we do:

$\frac{12 - 10}{2 - 1}$

Which equals to 2

So right now we can say that the equation is:

y=2x+b

In order to find b, the constant, we just need to plug in the y values and x value of a coordinate:

10=2(1)+b

10=2+b

8=b

So now we can say that the equation is:

y=2x+8
