You move 7 units to the right on the x-axis. Then you move 10 units down the y-axis the point will then be on quadrant IV

Answer:

Perimeter = 30

Step-by-step explanation:

hypotenuse = [tex]\sqrt{5^2+12^2}[/tex]

hypotenuse = [tex]\sqrt{25+144}[/tex]

hypotenuse = [tex]\sqrt{169}[/tex]

hypotenuse = 13

Perimeter = 5+12+13

Perimeter = 30

Answer:

a) the velocity of particle is -Aωsin (ωt + δ)

b) the velocity is zero when t =  (nπ - δ) / ω, n ∈ Z

Step-by-step explanation:

Given that;

s = A cos(ωt + δ)

(a)

Find the velocity of the particle at time t

the velocity of the particle is given as; v = ds/dt

so differentiate s = A cos(ωt + δ) on both sides with respect to t

v = ds/dt = d/dt [ A cos(ωt + δ) ]

v = A d/dt cos(ωt + δ)

v = -Asin(ωt + δ) d/dt(ωt + δ)

v = -Aωsin (ωt + δ)

therefore, the velocity of particle is -Aωsin (ωt + δ)

b)

When is the velocity 0?

Now since the velocity will be zero; lets set v = 0

-Aωsin (ωt + δ) = 0

sin (ωt + δ) = 0

ωt + δ = nπ

ωt = nπ - δ

t =  (nπ - δ) / ω, n ∈ Z

Therefore the velocity is zero when t =  (nπ - δ) / ω, n ∈ Z

Answer:

y=29

Step-by-step explanation:

Answer:

y=29

Step-by-step explanation:

We move all terms to the left:

58/y-(2)=0

The domain of the equation: y!=0

y∈R

We multiply all the terms by the denominator

-2*y+58=0

We add all the numbers together, and all the variables

-2y+58=0

We move all terms containing y to the left, all other terms to the right

-2y=-58

y=-58/-2

y=29

Answer:

x=8

y=4

Step-by-step explanation:

Answer:

Your point would be: (0,2)

x = 0

y = 2

Step-by-step explanation:

This would be the case if you're looking for the point by solving with substitution, or any other methods, of the systems of equations.

In any case, you are looking to find either x or y first.

I will demonstrate with the 'y' value, since it is easier when cancelling out the 'x' value.

2x - y = -2

2x + 4y = 8

(I want to make one of the two equations negative, so that I can eliminate or cancel out the 'x' value(s)).

- (2x - y = -2) --> -2x + y = 2

                          2x +4y = 8

---------------------------------------

                                5y = 10

                                ---     ---

                                 5      5

                              ------------

                                 y = 2

(Reason for putting a negative in front of the equation '2x - y = -2' was made in order to eliminate the value(s) '2x' in both equation, and in order to do that, one equation must be negative, while the other is positive, for example:

x + 2y = 6

x + 3y = 5

(You can make any of these equations negative, but only one equation is needed to be negative for the value you want to cancel out,

DO NOT TRY AND CANCEL OUT BOTH X AND Y)

-(x + 2y = 6)

Turn into:

-x - 2y = -6

x + 3y = 5

---------------

y = -1

(Back to the Original Problem)

We now need to find the 'x' value(s):

4(2x - y = -2)

8x - 4y = -8

2x + 4y = 8

----------------

10x = 0

---     ---

10     10

----------------

x = 0

Your final answer will be:

(0,2)

Answer:

I guess it's -2

Step-by-step explanation:

6-8x = 5x - 10x + 12

∴ 10x - 8x - 5x = 12 - 6

∴ 10x- 13x = 6

∴ - 3x = 6

∴ x = -6\3

∴ x = -2

Answer:

-2

Step-by-step explanation:

6-8x=5x-10x+12

5x-10x=-5x

=6-8x=-5x+12         MOVE -5x TO THE LEFT SIDE AND 6 TO THE RIGHT SIDE

= -8x+5x=12-6

= -3x=6

= -x=2

= x=-2

Answer:

4x-1>9

Step-by-step explanation:

4x>9+1

4x>10

x>2.5

Answer:

Please check the explanation.

Step-by-step explanation:

Given the table 1

x              y

-12           2

-10           10

0              -2

5              -6

8               -11

15              -15

From the table, it is clear that for each input there exists a unique output.

i.e.

According to the given table,

y = 2 at x=-12

y = 10 at x=-1 0

y = -1 at x=0

y = -11 at x=8

y = -15 at x=15

From the table, it is clear that for each input x, it has a unique output y.

Hence, table 1 is a function.

Given the table 2

x              y

9            -18

-20           0

-6              1

-17              16

9                17

11              19

This table does not produce a function, because the input x=9 produces two outputs.

i.e.

at x = 9, the y = -18

at x = 9, the y = 17

Therefore, the table 2 does not represent a function.

im not sure if this is right or not but i did the math and got 26

Step-by-step explanation:

Answer: 26

Step-by-step explanation:

Answer:

From the figure, it can be seen that ΔJ'K'L' is formed from ΔJKL by the rotation of ΔJKL by 90 degrees counter-clockwise.

It can also be seen that ΔJ"K"L" is obtained from ΔJ'K'L' by the refrection of ΔJ'K'L' across the x-axis.

Therefore, the rule that describes the composition of transformations that maps ΔJKL to ΔJ"K"L" is given by
