madreJ [45]2 years ago
5 0

Answer:

D

Step-by-step explanation:

If a function has x in the denominator, it cannot be a polynomial.

The rest of the options either don't apply to the equation, or are not rules for polynomials.

What is the equation of the line that is perpendicular to y = -2/3x + 4 and that passes through (–2,–2)?
Rama09 [41]

Answer:  y = 3/2x + 1

Step-by-step explanation:  For a perpendicular line, take the reciprocal of  "m"  and reverse the sign.

- 2/3 becomes +3/2

Then substitute the y and x values of the given coordinate into the equation and solve for "b"

y = mx + b

-2 = 3/2(-2) + b

-2 = -3 + b

-2 +3 = b

+1 = b   Substitute for b in y = (3/2)x + 1

{ x - 3y= -3 & x + y= 5 We are to use the graph to solve the given system of equations, then enter your solution below. I ge
nasty-shy [4]

Answer:

Solution: (3, 2)

Step-by-step explanation:

It's easier to graph when the equation of the lines are in their slope-intercept form, y = mx + b.

<u>x - 3y = -3</u>

-3y = -x - 3

Divide both sides by -3:

\frac{-3y}{-3}  = \frac{-x - 3}{-3}

y = 1/3x + 1

where slope = 1/3

y-intercept = 1

<u>x + y = 5</u>

Subtract x from both sides to isolate y:

x - x + y = - x + 5

y = -x + 5

where slope = -1  

y-intercept, 5

I started by graphing the y-intercepts of each line. Then, I used the slope of each linear equation (rise over run) to plot the next points on the graph. In the attached screenshot of the graph, <u>x - 3y = -3</u> is the blue line, while <u>x + y = 5</u> is the green line. Their intersection occurs at point, (3, 2).

Therefore, the solution is (3, 2).

Combine the like terms to create an equivalent expression: r+(−5r)
nevsk [136]

Answer:

-4r

Step-by-step explanation:

Since r and -5r both have the same variable, we can combine them

r-5r = -4r

r+(−5r) = -4r
