X2 + 2y ÷ w + 3z for w = 2, x = 5, y = 8, and z = 3?
melisa1 [442]

Step-by-step explanation:

w = 2

x = 5

y = 8

z = 3

= x² + 2y ÷ w + 3z

= (5)² + 2(8) ÷ (2) + 3(3)

= 25 + 16 ÷ 2 + 9

= 25 + 8 + 9

= 42

Liono4ka [1.6K]

Answer:

Q1.  2 - 5/ 8 - 0 = -3/8

Q2.  1- (-1)/6-2 = 2/4 simplified as 1/2

Q3.  (-5)- (-2)/ (-1)- (-3) = -3/2

Use a ruler to help you graph a line whose slope is 1/3. Label this line “a”

*Answer- 1/3 is being shown for rise/run (Rise over Run, 1 being rise and 3 being run). this means that you go up one and right 3.

Step-by-step explanation:

y2-y1 *over* x2- x1. Also if you can simplify the end fraction do it but if not then leav it as it is. This is the equation that I used for the first 3 problems. Also I didnt quit understand the 1st word problem sorry! I hope this helps :v

Which expression is a linear factor of x6 +x-66?
Naddik [55]

Answer:

Option D.

Step-by-step explanation:

The given expression is

x^6+x-66

It is a polynomial.

(x-c) is a linear factor of polynomial p(x) if p(c)=0.

Substitute x=-1 in the given expression.

(1)^6+(1)-66=-64\neq 0

It means (x+1) is not a linear factor of given expression.

Substitute x=-2 in the given expression.

(-2)^6+(-2)-66=-4\neq 0

It means (x+2) is not a linear factor of given expression.

Substitute x=-4 in the given expression.

(-4)^6+(-4)-66=4026\neq 0

It means (x+4) is not a linear factor of given expression.

None of the given options are a linear factor of given expression.

Therefore, the correct option is D.
