Which of the following is a solution of y - x &lt; -3?<br><br> (6, 2)<br> (2, 6)<br> (2, -1)
Snowcat [4.5K]
Personally I'd solve this inequality for y first:  y < x-3.

That immediately eliminates (6,2) and (2,6).

Starting from y < x-3 and letting 2 sub for x and -1 sub for y, is the following true or false?

-1 < 2 -3     NO.  -1 < -1 is false.  Was there a fourth answer choice?

What is the slope of a line whose graph is parallel to the graph of -3x+y=2?
liq [111]

Answer:

Step-by-step explanation:

if the lines are parallel they have the same gradient.

rearrange the equation to make y the subject and then use the m value as gradient.

-3x=2-y

-3x-2=-y

y=-(-3x-2)

y=3x+2

therefore m=3

slope is 3

What is y={-\dfrac{1}{3}}x-9y=− 3 1 ​ x−9y, equals, minus, start fraction, 1, divided by, 3, end fraction, x, minus, 9 written i
Kobotan [32]

Answer:

x+3y=-27

Step-by-step explanation:

We are given that

y=(-\frac{1}{3})x-9

We have to find the  standard form of given equation

y=\frac{-x-27}{3}

3y=-x-27

By using multiplication property of equality

x+3y=-27

We know that

Standard form of equation

ax+by=c

Therefore, the standard form of given equation  is given by

x+3y=-27

Which of the following shows the correct evaluation for the exponential expression 6 over 7 to the power of 2?
yaroslaw [1]
For this case we have the following expression:
 6 over 7 to the power of 2
 (6/7) ^ 2
 By power properties we can rewrite the expression as:
 (6/7) * (6/7)
 Calculating we have:
 (6/7) * (6/7) = 36/49
 Answer:
 
6 over 7 times 6 over 7 equals 36 over 49
