Point P, located at (-3,-4), is reflected across the y-axis.

What are the coordinates of this point after this transformation?

O (3,-4)

O(3,4)

O (4,3)

O (-3,4)​

Answers

Answer:

(3,-4)

Step-by-step explanation:

There is a graphing calculator called desmos that can help you answer questions like this, but, if you don't want to use that, you can just make a graph and imagine the transformation. Remember, when you reflect something over an axis, it is like you are folding the graph along the axis and your new point will be on the other side.

Answer:

(3,-4)

Step-by-step explanation:

The rule to follow for reflecting a figure across the y-axis is to take the original coordinate (x, y) and change it to (−x, y)

Answer:

GCF 35, 28 is 7

GCF 36, 27 is 9

Step-by-step explanation:

Greatest means biggest.

Common means same.

Factor means a number that goes evenly into the number. (3 goes into 27, so 3 is a factor of 27. 5 doesn't go evenly into 27, so 5 is not a factor of 27)

Is triangle EJH congruent to triangle EIH?

Answers

Answer: yes

Step-by-step explanation:

Side JH and side HI are congruent and angle J and angle I are congruent so the two triangles are also congruent

The given two triangles EJH and EIH are congruent by the RHS congruency rule of two triangles.

Congruence of triangles:

If two or more triangles having same size and shape, then they are congruent to each other.

Every angle and sides are must be equal to each other and hence area is also equal.

How to show congruence in right angled triangles?

Here we have given that two triangles EJH and EIH, both are right angled triangles.

In any two right angled triangles having same hypotenuse and base side then they are congruent to each other by the RHS congruency

Here we have given side HJ ≅ side HI

∠EJH = ∠EIH = 90°

The common side EH is hypotenuse for both that is side EH = side EH

Therefore by RHS criteria these two triangles are congruent.

Answers

The order of selecting the balls is an illustration of permutation and combination

The possible number of winning numbers is 269724312The possible number of winning numbers in order is 32366917440The possible number of winning numbers

The given parameters are:

Total white balls = 69Total red balls = 24

The possible number of winning numbers in any order is calculated using the following combination expression

[tex]n = ^{69}C_5 * ^{24}C_1[/tex]

This gives

[tex]n = 11238513* 24[/tex]

Evaluate the product

[tex]n = 269724312[/tex]

Hence, the possible number of winning numbers is 269724312

The possible number of winning numbers in order

When order is important, we make use of permutation.

So, we have:

[tex]n = ^{69}P_5 * ^{24}P_1[/tex]

This gives

[tex]n = 1348621560* 24[/tex]

Evaluate the product

Answers

Answer:

-11 yd/s

Step-by-step explanation:

We basically have to the find slope between the given points

Let h(t)₁ = 0

     h(t)₂ = 33

      t₁ = 6

      t₂ = 3

We have to find the change in distance (h(t)₁ - h(t)₂) then divide it by the change in x (t₁ - t₂)

6 - 3 = 3

This means the change of x is 3

0 - 33 = -33

This means the change in distance is -33

Now divide -33 by 3

-33 ÷ 3 = -11

Find the solution for x if |3 + 10x| = 23.

Answers

Answer:

x=2 and 2.6

Step-by-step explanation:

The required solutions for the given function |3 + 10x| = 23 are x = 2 and x = -2.6.

What is absolute value?

Absolute value is defined as the magnitude or size of a number, no negatives are allowed. The distance a number is from 0 on the number line is known as the absolute value of the number.  

The function is given in the question as:

|3 + 10x| = 23

To solve for x, we can begin by expressing the absolute value as a piecewise function:

|3 + 10x| = 23

(3 + 10x) = 23, if 3 + 10x ≥ 0

-(3 + 10x) = 23, if 3 + 10x < 0

If 3 + 10x ≥ 0, then 3 + 10x = 23, so x = (23 - 3) / 10 = 2.

If 3 + 10x < 0, then -(3 + 10x) = 23, so 3 + 10x = -23. This means that x = (-23 - 3) / 10 = -2.6.

Thus, the solutions for x are x = 2 and x = -2.6.

What are congruent triangles?

23) We are given a rectangle RSTU with diagonal US.

Now, we are told that;

UR is parallel to ST

∠R and ∠T are right angles

We can say that for ΔRSU and ΔTUS, that US is equal to itself in both cases by the reflexive property of congruence.

Now, since ∠R and ∠T are right angles, it means that UR is equal to ST.

Thus for the two triangles;

UR = ST

US = US

∠R = ∠T

There are two corresponding equal sides and one corresponding equal angle and as such, ΔRSU and ΔTUS are congruent by SAS congruency postulate.

18) We are given that;
