Explain and Show the equation of line perpendicular to y=-1x+2 going through the point (6, 3)

Answer:

y = x-3 is the equation

Step-by-step explanation:

If two lines are perpendicular, the product of their slopes is -1

The general equation form of a straight line is;

y = mx + b

Fro the equation;

y = -1x + 2

The slope is -1

So the equation of the perpendicular line is as follows;

-1 * m = -1

m = 1

so we can use the point-slope equation form

That would be:

y-y1 = m(x-x1)

y-3 = 1(x-6)

y-3 = x-6

y = x-6+3

y = x-3

The domain is about how far left-to-right the graph goes.
In relation to the x-axis, the graph starts at x = –3 (with an open circle at –3) and then continues over to the right forever.
This is the shown in the picture with the red markup.
In interval notation, this is (-3, infinity).

Remember to use that left-to-right orientation for interval notation!

The range is in turn about how low to how high the graph goes.
On the graph, I’d do the same thing I did on the red marked up graph and compare the graph to the y-axis.
The graph starts down at y = –5 (with an open circle at –5) and then continues on up forever.
In interval notation, this is (-5, infinity).

Don't guess!
Alja [10]

Answer:

The correct answer would be J; \frac{1}{2} r + 2;  

Step-by-step explanation:

Using the algebra;

\frac{1}{2}  * r = \frac{1}{2} r

\frac{1}{2} * 4 = 2

Altogether this would give "J" as the answer.

Hope this helps!

!!!!!!! Why isn't A the correct answer? I am having trouble to reason why A is wrong so please help if can!
docker41 [41]

Answer:

d.  x = -3

Step-by-step explanation:

<u />\sqrt{(x + 3)}÷ (x+8)(x-2) = 0

f(x) / g(x) = 0

Variable x cannot be equal to any of the values −8,2 since division by zero is not defined. Multiply both sides of the equation by (x−2)(x+8).

<u />\sqrt{(x + 3)} = 0 ------ square both sides

x + 3 = 0

solve for x:

x = -3

4.) Which best describes the relationship between &lt; AFB and &lt; AFD?
MAVERICK [17]

Answer:

C. Supplementary angles

Step-by-step explanation:

Given

<AFB = 72

Required

Relationship of <AFB and <AFD

<AFB and <AFD are on a straight line and angle on a straight line is 180

From the presentation of both angles,

<AFB + <AFD = 180

Substitute 72 for <AFB

72 + <AFD = 180

Make <AFB the subject of formula

<AFD = 180 - 72

<AFD = 108

Since both <AFB and <AFD sums to 180, then they are supplementary angles.

Hence, the relationship between both angles is supplementary angles

Allowing 20% discount on the marked price. of 아 a watch, the value of the watch will be Rs. 2378. If the VAT of 10% is added, fi
Harrizon [31]

Answer:

The marked price of the watch is $2,702.27.

Step-by-step explanation:

Since allowing 20% discount on the marked price of a watch, the value of the watch will be Rs. 2378, to determine, if the VAT of 10% is added, it's marked price, the following calculation must be performed:

1 - 0.2 = 0.8

0.8 x 1.1 = 2378

0.88 = 2378

0.88 = 2378

0.8 = X

0.8 x 2378 / 0.88 = X

1,902.4 / 0.88 = X

2,161.81 = X

0.8 = 2,161.81

1 = X

2,161.81 / 0.8 = X

2,702.27 = X

Therefore, the marked price of the watch is 2,702.27.
