hope I helped! I need to write more words so I can send this

**Answer:**

The answer is A

**Step-by-step explanation:**

|6x + 3| = 27

Use the definition of absolute value6x + 3 = 27

6x + 3 = -27

Subtract three from both sides of the equation.6x = 24

6x = -30

Divide both sides by 6.x = 4

x = -5

So:

x = 4, -5

One package of blueberries cost $3. How many packages of blueberries can you buy for $9?

Round the answer to the nearest whole number!

**Answer:**

3 packages

**Step-by-step explanation:**

To find how many packages you can buy for $9, you have to divide 9 by 3.

Since each package costs $3.

So, 9/3 = 3

So you can buy 3 packages of blueberries.

**Answer:**

3 Packages

**Step-by-step explanation:**

1 package costs $3

2 packages cost $6 (because 3+3=6)

3 packages cost $9- And we have exactly $9 so we can buy 3 packages.

What is the value of x?

**Answer:**

Option D is correct.

**Step-by-step explanation:**

We can tell that

[tex]4x + \frac{x}{2} + 2 + \frac{3x-4}{2} = 180[/tex]Now, let's simplify.

=> [tex]4x + 2 + \frac{4x-4}{2} = 180[/tex]

=> [tex]4x + 2 + 2x-2 = 180[/tex]

=> [tex]4x + 2x = 180[/tex]

=> [tex]6x = 180[/tex]

=> [tex]x = 30[/tex]

Therefore, Option D is correct.

Find two numbers whose sum is 36 and whose difference is 10.

**Answer:**

23 & 13

**Step-by-step explanation:**

23+13=36

**Answer:**

x = 23

y = 13

**Step-by-step explanation:**

Let the number be x and y.

As given,

x + y = 36 ---(i)

x - y = 10 ---(ii)

Adding eq(i) and eq(ii) we get,

2x = 46

x = 23

Now putting the value of x in eq(ii)

23 - y = 10

y = 13

So the two numbers are 23 and 13.

What is the area, in square units of the composite figure?

Enter your answer as a number, like this: 42

**Answer:**

280

**Step-by-step explanation:**

first, find the area of the triangle

formula: 1/2 (base × height)

so the area of the triangle is

= 1/2 (16×5)

= 1/2 (80)

= 40

then, find the area of the rectangle

formula: length × breadth

the area of the rectangle is

= 15 × 16

= 240

the area of the composite figure is the sum of the areas of the triangle and rectangle

= 40 + 240

= 280

Find the equation of the line passing through the points (-1,7) and

(2,-8). Write the equation in slope-intercept form.

A) y = -5x + 2

B) y = -5x + 7

C) y = 5x + 12

D) y = 5x – 18

Please help

A)

slop intercept form is y=mx+b

To find m, it is (y2-y1)/(x2-x1) or (-8-7)/(2-(-1)) which then = -5

To find b, the y-intercept choose one of the points and solve for b using:

y=x(slope)+b

7= -1( -5)+b

7= 5+b

2=b (subtract 5 on both sides)

I hope this helped!

what is the transformation of f(x)=|x-9|

**Answer: X=9**

**Step-by-step explanation:**

**Answer:**

f(x) = x-9 {9 < x}

f(x) = 0 {x = 9}

f(x) = -x - 9 {x < -9}

**Step-by-step explanation:**

I'm not too sure what transformation you want. However,,,

f(x)=|x-9| can be changed to function

f(x) = x-9 {9 < x}

f(x) = 0 {x = 9}

f(x) = -x - 9 {x < -9}

a^2 + b^2 = c^2

**Answer:**

The question cut off but I'm assuming this is basically just a find the area of the shaded region type of question. First thing you need to do is calculate the areas of the right triangle and the rectangle. Subtract the area of the triangle from the area of the rectangle.

Area of rectangle: 8 x 7 = 56ft^2

Area of the triangle: (6 x 2)/2 = 6ft^2

Subtract 6ft^2 from 56ft^2 and you get:

56 - 6 = **50ft^2**

**Area of shaded region is 50ft^2**

An architect designs two similar triangular patos. The first patio has angle measures of (x-30), (y+15), and 60 The second patio has angle measures of X -10 40° and 80°

The values of x and y are 50 and 35 respectively.

The corresponding angles of similar triangles are equal. Therefore,

The first patio angles are:

x + 10

y + 15

70°

The second patio angles are ;

x + 20

50°

60°

Therefore,

x + 20 = 70

x = 70 - 20

x = 50

y + 15 = 50

y = 50 - 15

y = 35

bottles of water, how much does a single bottle of water cost?

**Answer:**

$2.50

**Step-by-step explanation:**

1h + 2w = 9

3h + 4w = 22

Multiply the first expression x 3

3h + 6w = 27

Subtract the 2 equations

3h + 6w = 27

3h + 4w = 22

Determine which postulate or theorem can be used to prove that ASEA = A PEN E O A. ASA OB. SSS O C. AAS O D. SAS

**Answer:**

asa is the correct answer

The **postulate** or theorem can be used to prove that triangles are **congruent** is ASA rule.

Two **triangles** are said to be congruent when they have **congruent** corresponding parts.

Given is a figure having two **triangles**, we need to find the rule, that can prove that both the triangles are **congruent**,

∠ S ≅ ∠ P [given]

∠ SEA ≅ ∠ PEN [**vertically** opposite angles]

SE ≅ EP [given]

∴ Δ SEA ≅ Δ PEN by ASA rule

**ASA rule** :-

If any two angles and the side included between the angles of one triangle are **equivalent** to the corresponding two angles and side included between the angles of the second triangle, then the two triangles are said to be **congruent** by ASA rule.

Hence, the **postulate** or theorem can be used to prove that triangles are **congruent** is ASA rule.

4. Does the scatterplot have positive correlation, negative correlation, or no correlation?

Negative correlation

Positive correlation

O No correlation

Answer:

Negative Correlation

Step-by-step explanation:

Since the points are approximately lined up in a linear line pointing toward the bottom right, the slope of the best fit line would be a negative value. So the scatter plot shows a negative correlation.
