First One

If you distribute this
(x*x) + (x*8) + (x*1) + (8*1)
x^2 + 8x + 1x + 8
x^2 + 9x + 8

EXTRA POINTS :) what is the value of x??
vlada-n [284]

Answer:

x = 17

Step-by-step explanation:

corresponding interior angles are supplementary, meaning they have to add up to 180 degrees so

6x + 8 + 4x + 2 = 180°     then combine like terms ( 6x and 4x, 8 and 2 )

10x + 10 = 180         subtract 10 from both sides

        -10     -10

10x = 170            divide each side by 10

/10     /10

x = 17

Write the equation in slope-intercept form: 4x -2y =12
DedPeter [7]

4x - 2y = 12 \\   \:  \:  \:  \:  \:  \:  \frac{ - 2y}{ - 2}  =  \frac{ - 4x}{ - 2}  \:  +  \frac{12}{ - 2}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: y = 2x - 6

Therefore, the answer is 1) y = 2x - 6

kotegsom [21]

Answer:

q(p)= -3000p+12000

Step-by-step explanation:

For the function to be linear,

q(p)= mp + c

where

q(p): number of hamburgers sold

p: price per hamburger

m: gradient of the function

c: constant of the function

q(p)=6000 when p=2

6000=2m+c .................... equation I

0=4m+c

c=-4m........................ equation II

Substitute value of c in equation I

6000=2m-4m

m= -3000

c=12000

q(p)= -3000p+12000

Identiffy the degree of the polynomail 8x3y2 - 10x + 4x2y2+3
Karo-lina-s [1.5K]
8x^3y^2-10xy+4x^2y^2+3
If this is what you mean then the degree of the polynomial would be 3 since 3 is the highest exponent of all the terms.
