What is the mean of 7, 5, 10, and 2?
06
22
05
O 10

Answer:

The answer is D

Step-by-step explanation:

The rule best represents the dilation that has been applied to triangle JKL to create triangle J’K’L’ is (x, y) → (x + 4.5, y + 3).

Option B is the correct answer.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

From the graph,

J = (-2, 4)

K = (6, 4)

L = (8, -4)

And,

J' = (-3.5, 7)

K' = (10.5, 7)

L' = (14, -7)

Now,

If we apply the dilation:

(x, y) → (x + 4.5, y + 3) on JKL

We get,

J' = (-3.5, 7)

K' = (10.5, 7)

L' = (14, -7)

Thus,

The rule best represents the dilation that has been applied to triangle JKL to create triangle J’K’L’ is (x, y) → (x + 4.5, y + 3).

Answer:

c = 169

Step-by-step explanation:

Given

m² - 26m

To complete the square

add ( half the coefficient of the m- term)² to m² - 26m

m² + 2(- 13)m + (- 13)²

= m² - 26m + 169 ( with c = 169 )

= (m - 13)² ← perfect square

the answer is

[tex]x = \frac{n - c}{p + 1} [/tex]

Step-by-step explanation:

add x to both sides of the equation

subtract c from both sides of the equation

factor x out of px+x

divide each term by p+1 and simplify and that how you get your answer.

Answer:

A, B, C

Step-by-step explanation:

Use a^2 + b^2 = c^2 in each case.

A.

3^2 + (sqrt(27))^2 = 6^2

9 + 27 = 36

36 = 36

A. does form a right triangle.

B.

8^2 + 15^2 = 17^2

64 + 225 = 289

289 = 289

B. does form a right triangle.

C.

240 days

Step-by-step explanation:

Because she went 216 days but its 90% of the school year. we don't know how much days are actually in the school year so we do 90÷100x we had added a x to the 100 because of that. that equals 216 days. X equals 240 days. By 240=100% x=90% 240 divided

Answer:

n = 4

Step-by-step explanation:

Add the powers of 3

4 -5 -3 = - 4

Now these make just 1 power that you have to deal with.

3^-4

and that equates to 1/3 ^ n = 3^ -n

So what is the answer?

3^-4 = 3^-n

Since the bases are the same, the powers can be equated.

- 4 = - n

divide by - 1 to get 4 = n

Answer:

x = 55, y = 70, z = 125

Step-by-step explanation:

125 and x are adjacent angles and are supplementary, then

x = 180 - 125 = 55

The triangle is isosceles ( 2 congruent sides ) thus the base angles are congruent, both 55

The sum of the 3 angles in the triangle = 180° , thus

y = 180 - (55 + 55) = 180 - 110 = 70

55 and z are adjacent and supplementary, so

z = 180 - 55 = 125

Answers:

x = 55

y = 70

z = 125

============================================================

Explanation:

The tick marks indicate those two lines are the same length. We have an isosceles triangle. One base angle is x. The other missing base angle is also x, which is adjacent to angle z. The base angles of any isosceles triangle are always congruent.

Since the 125 and x degree angle form a straight line, they must add to 180

x+125 = 180

x = 180-125

x = 55

We can use this to find y

x+x+y = 180 .... three angles of any triangle always add to 180

2x+y = 180

2(55)+y = 180 .... plug in x = 55

110+y = 180

y = 180-110

y = 70

And,

x+z = 180

55+z = 180 ... plug in x = 55

z = 180-55

z = 125

Answer:

With the first four questions, all you need to do is find a value of x that gives you a zero value in any one of those brackets.  Let's do it.

You said you finished 1, so let's skip it.

I can't give you a full answer for question 2, because you didn't capture the entire expression in the screenshot.  I can see that the values 3 and 0.125 would give zero values, but I can't tell you the last.

For question three, we need to find x values where either 9x + 3 = 0, or x² - 9 = 0.  There are three values that meet those conditions.  You can solve it just by assigning a zero value and solving for x:

[tex]9x + 3 = 0\\3x + 1 = 0\\3x = -1\\x = -1/3[/tex]

For the second term actually has two solutions, because a squaring a number also causes negatives to be converted to positives.  Another way of seeing this is to notice that the second term is actually a difference of squares:

[tex]p(x) = (9x + 3)(x^2 - 9)\\= (9x + 3)(x + 3)(x - 3)[/tex]

so in this case x could be -1/3, -3, or 3 to give a zero value.

For question four, you can only get a zero if you use imaginary numbers, as no real number can be squared to give you a negative.  So the only answers to that are 5i, or -5i.

With questions five six seven and eight, we just need to make exceptions for zero denominators, so:

For question 5, you can x can be any real number except -4, 2 and 7

For 6, x can be anything but 3, 1/8th or 5

for 7, We again have that difference of squares, so the actual denominator is (9x + 3)(x + 9)(x - 9), meaning x can be anything but -1/3, -9, or 9

And finally for question 8, we again have a squaring, meaning that only an imaginary number will cause division by zero, meaning x can't be 5i or -5i.

Answer:

Clare is correct

Step-by-step explanation:

For two shapes to be congruent, the shape and size have to be the same. In other words they ate have to equal length in size and also equal angles(same shape hence equal angles).

Answer:

5 buckets

Step-by-step explanation:

If you have 36 dollars then you would subtract the amount it costs to get into the park:

$36 - $15 = $21

Then, you divide by 4 to see the maximum amount of buckets you can get:

$21/4 = 5 buckets that will be the maximum amount you can get
