What is the function of the line?

Answers

Answer:

It is a linear function.

Step-by-step explanation:

The graph shows a straight line. Therefore the function must be linear. Unless you were asking about the equation of the line? Let me know.

To find the equation of this line, you would take the two points it passes through, (-3, 0) and (0, -2), and plug it into the slope formula, (y2-y1)/(x2-x1).

This would get you (-2 - 0)/ (0 - (-3)), which is -2/3.

Then, you can use slope intercept form to write the equation, since you have the y intercept already, (0, -2).  Slope intercept is y=mx+b.

The line of the equation would then be y = -2/3x -2

Answer:

(3, -1)

Step-by-step explanation:

Multiply the 2nd equation (-2x-3y=-3) times -3 to eliminate x

Subtract/add the other terms -y + 9y and -17 + 9

Answer:

54w-9

Step-by-step explanation:

the box to the right is -1 because you are multiplying 6w-1 by 9 (the box next to the blank one on the bottom). the other blank box below the 6w is going to be 54w since you multiply 6w and 9 to get that. therefore, 9(6w-1) is 54w-9.

simplify

Answers

Step-by-step explanation:

given the expression

[tex]x^22y^4(x^2 - 16) - 9y^4(x^4 - 16)[/tex]

we proceed by opening the brackets

[tex]x^2y^4(x^2 - 16) - 9y^4(x^4 - 16) \\\\x^4y^4-16x^2y^4-9x^4y^4+144y^4\\\\[/tex]

collet like terms we have

[tex]x^4y^4-16x^2y^4-9x^4y^4+144y^4 \\\\x^4y^4-9x^4y^4-16x^2y^4+144y^4 \\\\8x^4y^4-16x^2y^4+144y^4[/tex]

factoring we have

solve for p
19/20=3p/18

Answers

Answer:

p=5.7

Step-by-step explanation:

Cross multiply.

Answer:

p = 5.7

Step-by-step explanation:

Given

[tex]\frac{19}{20}[/tex] = [tex]\frac{3p}{18}[/tex] ( cross- multiply )

60p = 19 × 18 = 342 ( divide both sides by 60 )

p = [tex]\frac{342}{60}[/tex] = [tex]\frac{57}{10}[/tex] = 5.7

What are the solution(s) of x2-4-0?

X=-4 or X-4
X=-2 or X= 2
X=2
X=4

Answers

Answer:

X = - 2 or X = 2

Step-by-step explanation:

*completing the square*

X^2 - 4 = 0

X^2 = 4

X = +-√4

x = +-2

x= -2, 2

*factoring*

X^2 - 4 = 0

(x-2)(x+2) = 0

|. |

x = 2, x = -2

________________________________

(x-2)(x+2) = x(x+2) - 2(x+2) = x^2 + 2x - 2x - 4 = x^2-4
