Answer: Yes

Explanation: look at the two points (-5, 1) it is basically (x, y). Now, if you plug in the values (1 = -5 + 6) it would make sense. So, yes it makes the equation true.

(Hope this helps!)

Which of the following numbers can be expressed as decimals that terminate? 5 over 2, 4 over 5, 2 over 7, 4 over 3 5 over 2 and

algol13

Answer:

I hope this helps!!

Step-by-step explanation:

We have given that : numbers - 9 over 7, 5 over 3, 3 over 2, 6 over 4

To find : which are terminating decimal

Terminating decimals are those whose figures to the right of some place are zero or have an end.

Solution : we check one by one,

1) 9 over 7 = 9/7 = 1.285714285714285714.... -Non terminating

2) 5 over 3 = 5/3 = 1.666666666666666...... -Non terminating

3) 3 over 2 = 3/2 = 1.5 - Terminating

4) 6 over 4 = 6/4= 3/2 = 1.5 - Terminating

I'm sorry if this is wrong :(

Write explicit equation for the sequence

Ray Of Light [21]

Step-by-step explanation:

r=14/7=28/14=56/28=2

So it is geometric

By using this equation:

a(n)=a1*(r)^(n-1)

and we have a(1)=7 , r=2

explicit equation : a(n)=7*(2)^(n-1)

hope this helps

Find mDCAˆ. the question says that the angle is 3x+19 the smaller arc is 91 and the bigger is 17x-3 it is one of those problems

valina [46]

Answer: Option C.

Step-by-step explanation:

Let as consider the below figure is attached below.

We know that angle between tangent and secant is half of difference of major and minor arcs.

$\angle ABC=\dfrac{arc(AD)-arc(AC)}{2}$

$3x+19=\dfrac{17x-3-91}{2}$

Multiply both sides by 2.

$6x+38=17x-94$

$38+94=17x-6x$

$132=11x$

Divide both sides by 11.

$12=x$

The value of x is 12.

$arc(AD)=17(12)-3$

$arc(AD)=204-3$

$arc(AD)=201^{\circ}$

Now,

$arc(DCA)=360^\circ-arc(AD)$

$arc(DCA)=360^\circ-201^{\circ}$

$m\widehat {DCA}=159^{\circ}$

Therefore, the correct option is C .

Find the coordinate point for A that would make ABDC a rhombus. coordinate plane with points B 3 comma 4, and C at 2 comma 1, an

mixer [17]

Answer:

B. (1, 3)

Step-by-step explanation:

We know the rhombus has perpendicular diagonals and the diagonals bisect each other.

The diagonals are AD and BC.

Note. The points C and D should have swapped coordinates. This becomes ABDC.

The midpoint of BC is:

([3 + 2]/2,[4 + 1]/2) = (2.5, 2.5)

Use A(x, y) and midpoint formula for the other diagonal AD:

(x + 4)/2 = 2.5 ⇒ x + 4 = 5 ⇒ x = 1
(y + 2)/2 = 2.5 ⇒ y + 2 = 5 ⇒ y = 3

Point A has coordinates (1, 3)

Correct choice is B

See the picture
